RE: [XMakemol-discuss] Problems installing xmakemol

[Berit Hinnemann]

Hi Matt,

I am not sure what to enter, because if I try out these commands I get

address@hidden xmakemol-5.15]$ CC="gcc -m64" ./configure
CC=gcc -m64: Command not found.
address@hidden xmakemol-5.15]$ CC="gcc -m32" ./configure
CC=gcc -m32: Command not found.
address@hidden xmakemol-5.15]$

Could you explain a bit more what you would like me to try? Is there another
way I can find out what the default mode of gcc is?

Thanks,
Berit

I don't have access to an Opteron machine so can't test locally.  Is
there a problem with the development libraries being 32-bit and the
default mode of GCC being 64-bit (or vice versa)?  If so, maybe you
could try:

    CC="gcc -m64" ./configure

or

    CC="gcc -m32" ./configure
