[Gcl-devel] gcl compilation with gcc 6.2.1 20161209

[Wolfgang Brehm]

Hi

I am trying to compile GCL with a more recent version of gcc.

gcc   -o raw_pre_gcl  -L.  -Wl,-Map raw_pre_gcl_map  -lpre_gcl -lX11    -lm  -lreadline -lc -lgclp  
./libpre_gcl.a(alloc.o): In function `m__gmpz_add':
alloc.c:(.text+0x4a00): multiple definition of `m__gmpz_add'

...

gcc --version

gcc (SUSE Linux) 6.2.1 20161209 [gcc-6-branch revision 243481]

I suppose this is because of multiple linking or multiple inclusion of gmp. I am experimenting with adding include guards or different compiling and linking options, any suggestions?

Thank you very much in advance for any advice I should recieve,
