This file describes how to make a threaded X11R6.
You need the source-code of XFree-3.2. I used the sources of X11R6.1
(files: xc-1.tar.gz xc-2.tar.gz xc-3.tar.gz) and the patches to
XFree-3.2 (files: README.X11.patch R6.1pl1-3.2.diff.gz cfont32.tgz).
Untar the xc-?.tar.gz files in a directory called XF3.2 and apply
the XFree-3.2 patches as described in README.X11.patch or use the
whole XFree86 source.
Now apply the thread patch with
patch -p0 < XF3.2.xc.diff
Go to the XF3.2/xc directory and make the whole thing:
nice make World >& world.log &
tail -f world.log
Wait a few hours or interrupt the process after the shared libs
are made. The shared libs are:
XF3.2/xc/lib/ICE/libICE.so.6.0*
XF3.2/xc/lib/PEX5/libPEX5.so.6.0*
XF3.2/xc/lib/SM/libSM.so.6.0*
XF3.2/xc/lib/X11/libX11.so.6.1*
XF3.2/xc/lib/XIE/libXIE.so.6.0*
XF3.2/xc/lib/XThrStub/libXThrStub.so.6.0*
XF3.2/xc/lib/Xaw/libXaw.so.6.1*
XF3.2/xc/lib/Xext/libXext.so.6.1*
XF3.2/xc/lib/Xi/libXi.so.6.0*
XF3.2/xc/lib/Xmu/libXmu.so.6.0*
XF3.2/xc/lib/Xt/libXt.so.6.0*
XF3.2/xc/lib/Xtst/libXtst.so.6.1*
(The Program dga didn't compile, but I have not check out why.)
Now you can copy the resulting libs
cp XF3.2/xc/lib/*/*.so.?.? /usr/X11R6/lib/
and create some links
cd /usr/X11R6/lib/
ln -s libXThrStub.so.6.0 libXThrStub.so.6
ln -s libXThrStub.so.6 libXThrStub.so
or use make install (not tested, and needs new configuration).
It is possible with the libXThrSub to compile X11 programs without linking
libpthread to them and not necessary to recompile already installed
unthreaded X11 programs, because libXThrSub keeps the dynamic linker quit.
On the other hand you can link libpthread to a X11 program to use threads.
I used linux 2.0.23 and libc 5.4.7 .
