Compiling TeX binaries on Solaris
(The document describes the procedures used on Sparc Solaris binaries,
but the same rules should apply to i386 and x86_64 as well.)
Solaris 9 has been out of official support for a while and making
software compile on that platform is challenging, so it hardly makes any
sense to try to support it.
Solaris 10 reaches end of support in January 2021:
http://en.wikipedia.org/wiki/Solaris_(operating_system)#Version_history
and TeX Live binaries try to stay compatible with that OS version.
Every once in a while a new Update is shipped:
U1 2006-01
U2 2006-06
U3 2006-11
U4 2007-08
U5 2008-05
U6 2008-10
U7 2009-05
U8 2009-10
U9 2010-09
U10 2011-08
U11 2013-01
and the problem is that binaries compiled on an updated system might not
run on an older one.
You can check the libc version with
> pvs -no /usr/lib/libc.so
> pvs -d /lib/libc.so.1 | grep SUNW
SUNW_1.23;
SUNW_1.22.7;
SUNW_1.22.6;
/.../
SUNW_1.1;
SUNW_0.9;
SUNW_0.8;
SUNW_0.7;
Building wget
=============
Building wget on the latest version of Solaris 10 will make the binary
useless on older Updates of Solaris 10 as it would depend on SUNW_1.22.7.
One option to build wget in a "compatible way" would be to build it on
Solaris 9 with "cc". The other hack is the usage of map files.
To make it work on older systems the following hack was used (thanks to
the OpenCSW community):
https://buildfarm.opencsw.org/source/xref/opencsw/csw/mgar/pkg/wget/trunk/files/map.wget
> cat mapfile
libc.so - SUNW_1.22.5 SUNWprivate_1.1 $ADDVERS=SUNW_1.22.5;
export LD_OPTIONS="-M $PWD/mapfile"
And the following configuration was used to get rid of dependencies (which
are not installed on Solaris by default):
> ./configure --enable-ipv6 --disable-iri --disable-nls \
--disable-ntlm --disable-pcre --without-libiconv-prefix \
--without-libintl-prefix --without-libuuid --without-libpsl \
--without-ssl --without-zlib
The binary was built with gcc 4.9.2.
> pvs Master/tlpkg/installer/wget/wget.sparc-solaris
libsocket.so.1 (SUNW_1.4);
libnsl.so.1 (SUNW_1.7);
librt.so.1 (SUNW_1.2);
libc.so.1 (SUNW_1.22.5, SUNWprivate_1.1);
> ./Master/tlpkg/installer/wget/wget.sparc-solaris --version
GNU Wget 1.16.3 built on solaris2.10.
+digest -https +ipv6 -iri +large-file -nls -ntlm +opie -psl -ssl
(That list of configure options is current as of the above version of
wget; not all those dependencies are present in earlier versions.)
Building xz
===========
The xz binaries would likewise depend on SUNW_1.22.6 by default, so we
used the same hack with a map file to make it work on slightly older
systems.
> export LD_OPTIONS="-M $PWD/mapfile"
> ./configure --disable-nls --disable-shared
> pvs Master/tlpkg/installer/xz/xz.sparc-solaris
librt.so.1 (SUNW_1.2);
libpthread.so.1 (SUNW_1.2);
libc.so.1 (SUNW_1.22);
> pvs Master/tlpkg/installer/xz/xzdec.sparc-solaris
libc.so.1 (SUNW_1.22);
If users need binaries to run on even older systems, we can target what
is desired by changing the map file.
Building texlive
================
Two extra settings were needed to compile TeX Live with gcc 5.2:
* export LIBPNG_USER_CPPFLAGS="-D_XOPEN_SOURCE=600"
* ./Build --without-iconv
The second option makes sure to avoid linking against libiconv
which is not available on SunOS by default.
The first option is only needed on Solaris 10 to circumvent a problem
in libpng <https://sourceforge.net/p/libpng/bugs/245/>.
Using `#define _POSIX_SOURCE 1` will fail to compile on Solaris 10 with gcc 5.x
unless one of `_XPG6`, `_XOPEN_SOURCE = 600`, or `_POSIX_C_SOURCE = 200112L` is set.
