I have two nearly identical 64-bit Linux systems, one of which runs OpenSuSE 12.1 and the other 11.4. Running an identical build script on both has different effects, neither of which is entirely correct. Under 12.1, it builds the 64-bit libraries correctly, but does not build the 32-bit cilkrts or tsan ones, which is a very minor problem as I regard 32-bit as obsolete for such systems. Under 11.4, it does the same, but also installs the cilkrts libraries into the 32-bit directory! There is a difference in the build output, where they say (respectively):
Libraries have been installed in:
/home/nmm/CilkPlus/lib64/../lib64
Libraries have been installed in:
/home/nmm/CilkPlus/lib/../lib64
Manually moving the libraries into the right directory works. The build script is:
#!/bin/sh
set -eux
export PATH=/home/nmm/GCC/bin:$PATH
svn update svn://gcc.gnu.org/svn/gcc/branches/cilkplus
# mkdir object /home/nmm/CilkPlus
cd object
../configure --prefix=/home/nmm/CilkPlus --disable-bootstrap \
--enable-languages=c,c++,fortran \
--enable-werror=yes --disable-decimal-float
# --enable-werror=yes --enable-checking=all --disable-decimal-float
make
make install
and the update script is:
#!/bin/sh
set -eux
export PATH=/home/nmm/GCC/bin:$PATH
svn update
cd object
make
make install
I can easily insert diagnostics into the building mechanism, if that would help.
