question about compiling polymake in ubuntu 14.04

[vissarion]

Hello,

I'm trying to compile polymake 2.13-1 on an Ubuntu 14.04 LTS and get the following error.

Code: Select all

g++ -shared -L/usr/local/lib -fstack-protector -o ../../lib/graph.so GraphIso.o ../../staticlib/nauty/libnauty.a -lmpfr -lgmp -lpthread /usr/bin/ld: ../../staticlib/nauty/libnauty.a(naugraph.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC ../../staticlib/nauty/libnauty.a: error adding symbols: Bad value collect2: error: ld returned 1 exit status make[1]: *** [../../lib/graph.so] Error 1 make[1]: Leaving directory `/home/vissarion/workspace/polymake-2.13-1/build.x86_64/bundled/nauty/apps/graph' make: *** [compile] Error 2

I recompiled nauty inside build.x86_64/bundled/nauty/staticlib/nauty with -fPIC but I still get the same error message.
I got the same error also with the current polymake version from github.

I'll appreciate any help or comment.

Thanks

Actually, -fPIC should be added automatically by configuration script at the very beginning and applied to all object files, not only libnauty.

Please look into build.x86_64/conf.make and check whether it contains a line like this:

CsharedFlags := -fPIC

If yes, please recompile everything: make clean; make all

If not, please tell your GCC version; also please post the complete contents of conf.make.

Hello. Thanks for your reply!

The answer is yes, "CsharedFlags := -fPIC" is contained. I make clean and then make all but I still got the same error.

However, I managed to compile the polymake Perpetual Beta, so I am ok with it! (nauty is replaced by bliss and this probably fixes my problem).

For your information I post my conf.make.
