It is written in the POD format (see pod/perlpod.pod) which is +specially designed to be readable as is. + +=head1 NAME + +README.cygwin - Perl for Cygwin + +=head1 SYNOPSIS + +This document will help you configure, make, test and install Perl +on Cygwin. This document also describes features of Cygwin that will +affect how Perl behaves at runtime. + +B<NOTE:> There are pre-built Perl packages available for Cygwin and a +version of Perl is provided in the normal Cygwin install. If you do +not need to customize the configuration, consider using one of those +packages. + + +=head1 PREREQUISITES FOR COMPILING PERL ON CYGWIN + +=head2 Cygwin = GNU+Cygnus+Windows (Don't leave UNIX without it) + +The Cygwin tools are ports of the popular GNU development tools for Win32 +platforms. They run thanks to the Cygwin library which provides the UNIX +system calls and environment these programs expect. More information +about this project can be found at: + + F<http://www.cygwin.com/> + +A recent net or commercial release of Cygwin is required. + +At the time this document was last updated, Cygwin 1.5.24 was current. + + +=head2 Cygwin Configuration + +While building Perl some changes may be necessary to your Cygwin setup so +that Perl builds cleanly. These changes are B<not> required for normal +Perl usage. + +B<NOTE:> The binaries that are built will run on all Win32 versions. +They do not depend on your host system (Win9x/WinME, WinNT/Win2K) +or your Cygwin configuration (I<ntea>, I<ntsec>, binary/text mounts). +The only dependencies come from hard-coded pathnames like C</usr/local>. +However, your host system and Cygwin configuration will affect Perl's +runtime behavior (see L</"TEST">). + +=over 4 + +=item * C<PATH> + +Set the C<PATH> environment variable so that Configure finds the Cygwin +versions of programs. Any Windows directories should be removed or +moved to the end of your C<PATH>. + +=item * I<nroff> + +If you do not have I<nroff> (which is part of the I<groff> package), +Configure will B<not> prompt you to install I<man> pages. + +=item * Permissions + +On WinNT with either the I<ntea> or I<ntsec> C<CYGWIN> settings, directory +and file permissions may not be set correctly. Since the build process +creates directories and files, to be safe you may want to run a +C<chmod -R +w *> on the entire Perl source tree. + +Also, it is a well known WinNT "feature" that files created by a login +that is a member of the I<Administrators> group will be owned by the +I<Administrators> group. Depending on your umask, you may find that you +can not write to files that you just created (because you are no longer +the owner). When using the I<ntsec> C<CYGWIN> setting, this is not an +issue because it "corrects" the ownership to what you would expect on +a UNIX system. + +=back + +=head1 CONFIGURE PERL ON CYGWIN + +The default options gathered by Configure with the assistance of +F<hints/cygwin.sh> will build a Perl that supports dynamic loading +(which requires a shared F<libperl.dll>). + +This will run Configure and keep a record: + + ./Configure 2>&1 | tee log.configure + +If you are willing to accept all the defaults run Configure with B<-de>. +However, several useful customizations are available. + +=head2 Stripping Perl Binaries on Cygwin + +It is possible to strip the EXEs and DLLs created by the build process. +The resulting binaries will be significantly smaller. If you want the +binaries to be stripped, you can either add a B<-s> option when Configure +prompts you, + + Any additional ld flags (NOT including libraries)? [none] -s + Any special flags to pass to g++ to create a dynamically loaded library? + [none] -s + Any special flags to pass to gcc to use dynamic linking? [none] -s + +or you can edit F<hints/cygwin.sh> and uncomment the relevant variables +near the end of the file. + +=head2 Optional Libraries for Perl on Cygwin + +Several Perl functions and modules depend on the existence of +some optional libraries. Configure will find them if they are +installed in one of the directories listed as being used for library +searches. Pre-built packages for most of these are available from +the Cygwin installer. + +=over 4 + +=item * C<-lcrypt> + +The crypt package distributed with Cygwin is a Linux compatible 56-bit +DES crypt port by Corinna Vinschen. + +Alternatively, the crypt libraries in GNU libc have been ported to Cygwin. + +The DES based Ultra Fast Crypt port was done by Alexey Truhan: + + ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/porters/Okhapkin_Sergey/cw32crypt-dist-0.tgz + +NOTE: There are various export restrictions on DES implementations, +see the glibc README for more details. + +The MD5 port was done by Andy Piper: + + ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/porters/Okhapkin_Sergey/libcrypt.tgz + +=item * C<-lgdbm_compat> (C<use GDBM_File>) + +GDBM is available for Cygwin. + +NOTE: The GDBM library only works on NTFS partitions. + +=item * C<-ldb> (C<use DB_File>) + +BerkeleyDB is available for Cygwin. + +NOTE: The BerkeleyDB library only completely works on NTFS partitions +and db-4.3 is flawed. + +=item * C<cygserver> (C<use IPC::SysV>) + +A port of SysV IPC is available for Cygwin. + +NOTE: This has B<not> been extensively tested. In particular, +C<d_semctl_semun> is undefined because it fails a Configure test +and on Win9x the I<shm*()> functions seem to hang. It also creates +a compile time dependency because F<perl.h> includes F<<sys/ipc.h>> +and F<<sys/sem.h>> (which will be required in the future when compiling +CPAN modules). CURRENTLY NOT SUPPORTED! + +=item * C<-lutil> + +Included with the standard Cygwin netrelease is the inetutils package +which includes libutil.a. + +=back + +=head2 Configure-time Options for Perl on Cygwin + +The F<INSTALL> document describes several Configure-time options. Some of +these will work with Cygwin, others are not yet possible. Also, some of +these are experimental. You can either select an option when Configure +prompts you or you can define (undefine) symbols on the command line. + +=over 4 + +=item * C<-Uusedl> + +Undefining this symbol forces Perl to be compiled statically. + +=item * C<-Uusemymalloc> + +By default Perl uses the C<malloc()> included with the Perl source. If you +want to force Perl to build with the system C<malloc()> undefine this symbol. + +=item * C<-Uuseperlio> + +Undefining this symbol disables the PerlIO abstraction. PerlIO is now the +default; it is not recommended to disable PerlIO. + +=item * C<-Dusemultiplicity> + +Multiplicity is required when embedding Perl in a C program and using +more than one interpreter instance. This works with the Cygwin port. + +=item * C<-Duse64bitint> + +By default Perl uses 32 bit integers. If you want to use larger 64 +bit integers, define this symbol. + +=item * C<-Duselongdouble> + +I<gcc> supports long doubles (12 bytes). However, several additional +long double math functions are necessary to use them within Perl +(I<{atan2, cos, exp, floor, fmod, frexp, isnan, log, modf, pow, sin, sqrt}l, +strtold>). +These are B<not> yet available with Cygwin. + +=item * C<-Dusethreads> + +POSIX threads are implemented in Cygwin, define this symbol if you want +a threaded perl. + +=item * C<-Duselargefiles> + +Cygwin uses 64-bit integers for internal size and position calculations, +this will be correctly detected and defined by Configure. + +=item * C<-Dmksymlinks> + +Use this to build perl outside of the source tree. This works with Cygwin. +Details can be found in the F<INSTALL> document. This is the recommended +way to build perl from sources. + +=back + +=head2 Suspicious Warnings on Cygwin + +You may see some messages during Configure that seem suspicious. + +=over 4 + +=item * Win9x and C<d_eofnblk> + +Win9x does not correctly report C<EOF> with a non-blocking read on a +closed pipe. You will see the following messages: + + But it also returns -1 to signal EOF, so be careful! + WARNING: you can't distinguish between EOF and no data! + + *** WHOA THERE!!! *** + The recommended value for $d_eofnblk on this machine was "define"! + Keep the recommended value? [y] + +At least for consistency with WinNT, you should keep the recommended +value. + +=item * Compiler/Preprocessor defines + +The following error occurs because of the Cygwin C<#define> of +C<_LONG_DOUBLE>: + + Guessing which symbols your C compiler and preprocessor define... + try.c:<line#>: missing binary operator + +This failure does not seem to cause any problems. With older gcc +versions, "parse error" is reported instead of "missing binary +operator". + +=back + +=head1 MAKE ON CYGWIN + +Simply run I<make> and wait: + + make 2>&1 | tee log.make + +=head1 TEST ON CYGWIN + +There are two steps to running the test suite: + + make test 2>&1 | tee log.make-test + + cd t; ./perl harness 2>&1 | tee ../log.harness + +The same tests are run both times, but more information is provided when +running as C<./perl harness>. + +Test results vary depending on your host system and your Cygwin +configuration. If a test can pass in some Cygwin setup, it is always +attempted and explainable test failures are documented. It is possible +for Perl to pass all the tests, but it is more likely that some tests +will fail for one of the reasons listed below. + +=head2 File Permissions on Cygwin + +UNIX file permissions are based on sets of mode bits for +{read,write,execute} for each {user,group,other}. By default Cygwin +only tracks the Win32 read-only attribute represented as the UNIX file +user write bit (files are always readable, files are executable if they +have a F<.{com,bat,exe}> extension or begin with C<#!>, directories are +always readable and executable). On WinNT with the I<ntea> C<CYGWIN> +setting, the additional mode bits are stored as extended file attributes. +On WinNT with the default I<ntsec> C<CYGWIN> setting, permissions use the +standard WinNT security descriptors and access control lists. Without one of +these options, these tests will fail (listing not updated yet): + + Failed Test List of failed + ------------------------------------ + io/fs.t 5, 7, 9-10 + lib/anydbm.t 2 + lib/db-btree.t 20 + lib/db-hash.t 16 + lib/db-recno.t 18 + lib/gdbm.t 2 + lib/ndbm.t 2 + lib/odbm.t 2 + lib/sdbm.t 2 + op/stat.t 9, 20 (.tmp not an executable extension) + +=head2 NDBM_File and ODBM_File do not work on FAT filesystems + +Do not use NDBM_File or ODBM_File on FAT filesystem.

However, in addition to the items noted above, there are +some differences that you should know about. This is a very brief guide +to portability, more information can be found in the Cygwin documentation. + +=over 4 + +=item * Pathnames + +Cygwin pathnames can be separated by forward (F</>) or backward (F<\\>) +slashes. They may also begin with drive letters (F<C:>) or Universal +Naming Codes (F<//UNC>). DOS device names (F<aux>, F<con>, F<prn>, +F<com*>, F<lpt?>, F<nul>) are invalid as base filenames. However, they +can be used in extensions (e.g., F<hello.aux>). Names may contain all +printable characters except these: + + : * ? " < > | + +File names are case insensitive, but case preserving. A pathname that +contains a backslash or drive letter is a Win32 pathname (and not subject +to the translations applied to POSIX style pathnames). + +For conversion we have C<Cygwin::win_to_posix_path()> and +C<Cygwin::posix_to_win_path()>. + +Pathnames may not contain Unicode characters. C<Cygwin> still uses the +ANSI API calls and no Unicode calls because of newlib deficiencies. +There's an unofficial unicode patch for cygwin at +F<http://www.okisoft.co.jp/esc/utf8-cygwin/> + +=item * Text/Binary + +When a file is opened it is in either text or binary mode. In text mode +a file is subject to CR/LF/Ctrl-Z translations. With Cygwin, the default +mode for an C<open()> is determined by the mode of the mount that underlies +the file. See C<Cygwin::is_binmount()>. Perl provides a C<binmode()> function +to set binary mode on files that otherwise would be treated as text. +C<sysopen()> with the C<O_TEXT> flag sets text mode on files that otherwise +would be treated as binary: + + sysopen(FOO, "bar", O_WRONLY|O_CREAT|O_TEXT) + +C<lseek()>, C<tell()> and C<sysseek()> only work with files opened in binary +mode. + +The text/binary issue is covered at length in the Cygwin documentation. + +=item * PerlIO + +PerlIO overrides the default Cygwin Text/Binary behaviour. A file will +always be treated as binary, regardless of the mode of the mount it lives +on, just like it is in UNIX. So CR/LF translation needs to be requested in +either the C<open()> call like this: + + open(FH, ">:crlf", "out.txt"); + +which will do conversion from LF to CR/LF on the output, or in the +environment settings (add this to your .bashrc): + + export PERLIO=crlf + +which will pull in the crlf PerlIO layer which does LF -> CRLF conversion +on every output generated by perl. + +=item * F<.exe> + +The Cygwin C<stat()>, C<lstat()> and C<readlink()> functions make the F<.exe> +extension transparent by looking for F<foo.exe> when you ask for F<foo> +(unless a F<foo> also exists). Cygwin does not require a F<.exe> +extension, but I<gcc> adds it automatically when building a program. +However, when accessing an executable as a normal file (e.g., I<cp> +in a makefile) the F<.exe> is not transparent. The I<install> included +with Cygwin automatically appends a F<.exe> when necessary. + +=item * Cygwin vs. Windows process ids + +Cygwin processes have their own pid, which is different from the +underlying windows pid. Most posix compliant Proc functions expect +the cygwin pid, but several Win32::Process functions expect the +winpid. E.g. C<$$> is the cygwin pid of F</usr/bin/perl>, which is not +the winpid. Use C<Cygwin::winpid_to_pid()> and C<Cygwin::winpid_to_pid()> +to translate between them. + +=item * Cygwin vs. Windows errors + +Under Cygwin, $^E is the same as $!. When using L<Win32 API Functions|Win32>, +use C<Win32::GetLastError()> to get the last Windows error. + +=item * C<chown()> + +On WinNT C<chown()> can change a file's user and group IDs. On Win9x C<chown()> +is a no-op, although this is appropriate since there is no security model. + +=item * Miscellaneous + +File locking using the C<F_GETLK> command to C<fcntl()> is a stub that +returns C<ENOSYS>. + +Win9x can not C<rename()> an open file (although WinNT can). + +The Cygwin C<chroot()> implementation has holes (it can not restrict file +access by native Win32 programs). + +Inplace editing C<perl -i> of files doesn't work without doing a backup +of the file being edited C<perl -i.bak> because of windowish restrictions, +therefore Perl adds the suffix C<.bak> automatically if you use C<perl -i> +without specifying a backup extension. + +Using C<fork()> after loading multiple dlls may fail with an internal cygwin +error like the following: + + C:\CYGWIN\BIN\PERL.EXE: *** couldn't allocate memory 0x10000(4128768) for 'C:\CYGWIN\LIB\PERL5\5.6.1\CYGWIN-MULTI\AUTO\SOCKET\SOCKET.DLL' alignment, Win32 error 8 + + 200 [main] perl 377147 sync_with_child: child -395691(0xB8) died before initialization with status code 0x1 + 1370 [main] perl 377147 sync_with_child: *** child state child loading dlls + +Use the rebase utility to resolve the conflicting dll addresses.
