| Description: |
When compiling Tk8.5.11 on a x86_64 multilib linux system for a 32-bit native target, configuring the build (with a config.site script) to use CC="gcc -m32 -march i686", the resulting Makefile shows:
X11_LIB_SWITCHES= -L/usr/lib64 -lX11 $(XFT_LIBS)
The explicit search path /usr/lib64 is misleading because the linker will find 64-bit libraries only in that place. It doesn't break the build, but it produces a lot of messages like these:
gcc -m32 -march=i686 -g -pipe -Wl,--export-dynamic tkAppInit.o -L/usr/local/src/BUILD/i686-linux/tk8.5.11 -ltk8.5 \
-L/usr/local/src/BUILD/i686-linux/tcl8.5.11 -ltcl8.5 -L/usr/lib64 -lX11 -ldl -lieee -lm -Wl,-rpath,/usr/local/lib -o wish

This is a Tk issue bgriffin added on 2013-01-28 05:00:22: I've been having a similar problem on SuSE Enterprise 10.4 and here's what I learned. To begin with, the --disable-64bit option doesn't work when it comes to just the basic compiler, which is why CC="gcc -m32" is required in the first place. This shouldn't be necessary. I found a missing link in /usr/lib libfreetype.so -> libfreetype.so.6, libfontconfig.so -> libfontconfig.so.1 Because the linker was looking for lib<name>.so for -lfreetype -lfontconfig, it failed to find it and then tried /usr/lib64 which gives the misleading error message about incompatible libraries. The xft-config script does not, and cannot, report the correct options for 32-bit xft library usage. This causes the configure script to feed the wrong options to the test compiles. There are more problems then I could sort out with the configure script and the underlying OS support for 32-bit development. Bottom line is the SuSE environment is screwed up when it comes to 32-bit development. Much of the OS seems to make a base assumption that it's 64-bit all the time and 32-bit is reluctantly present for legacy support of existing programs. eriklns added on 2012-06-14 04:08:17: File Added - 446030: config.log | |||
