$Id$ Public domain. Originally written 2005 by Karl Berry. For a high-level overview of building TeX Live, see http://tug.org/texlive/build.html. In brief: To configure and make the source tree, run ./Build. To build (mostly) without optimization, run ./Build --debug. To make without configuring, run TL_CONFIGURE=true ./Build. Email tlbuild@tug.org if problems. (Nearly everything the Build script does can be overridden via environment variables; just take a look to see the names.) Many more details about the TL build system, such as configuring to work on a single program, adding new programs or libraries, recompiling after fixing problems, etc., are in the doc/tlbuild* document and the sibling README* files here (which are generated from that document). Build information for some of the platforms. i386-linux: gcc 4.9.2, Linux 2.6.18-* (CentOS 5.10, tug.org:~karl/bin/mybuild) Except for dvisvgm, where we must use the system compiler (gcc 4.1.2, Red Hat 4.1.2-54) or libgs.so crashes trying to use gcc 4.8.2's libstdc++. On the other hand, the system compiler has an optimization bug that causes lcdf-typetools's tfm.test to fail, so it can't be used for everything. Sigh. x86_64-linux: gcc 4.8.2, libc 2.3.6, Linux 2.6.28.6 amd64-netbsd: gcc version 4.5.3 (NetBSD nb2 20110806) NetBSD/amd64 6.1.3 TL_MAKE=gmake LDFLAGS='-L/usr/X11R7/lib -Wl,-rpath,/usr/X11R7/lib' ./Build i386-openbsd, amd64-openbsd: e.g., see CONFIGURE_ARGS in the Makefile in http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/print/texlive/base/ i386-solaris, x86_64-solaris: Solaris 10. See doc/README.solaris. i386-cygwin, x86_64-cygwin: gcc-4.8.2, cygwin-1.7.29. ./Build (with --enable-xindy for i386). powerpc-linux (Debian Squeeze): Linux homer 2.6.32-5-powerpc64 #1 SMP Tue Mar 8 02:01:42 UTC 2011 ppc64 Debian GNU/Linux 6.0 (only the kernel is 64bit, the entire userland is 32bit) sparc-solaris: Solaris 10, gcc.
