ABINIT Discussion Forums

Hello,

I am trying to build abinit latest version on a Cray using the gnu compiler ( I tried different versions ) and I get the following syntax error. Is this a known problem?

Thanks

libtool: compile: CC -DHAVE_CONFIG_H -I. -I.. -I/lus/scratch/cpsosa/csm/abinit-6.12.1/tmp/fallbacks/exports/include -O3 -MT lda.lo -MD -MP -MF .deps/lda.Tpo -c lda.c -o lda.o

LibXC makes a heavy use of preprocessing. You should check that your setting of CPP is consistent with your compiler. In your case, I guess that not setting it manually has induced the build system of abinit to detect another - probably incompatible - C preprocessor.

Please contact directly the developers of LibXC if the problem persists.

Thanks. Do you know what is the best way to contact the libxc developers?

Problem solved, I was using CC=CC which compiles c code with c++ compiler that is more restrictive. CC=cc.
