Hello,
I'm trying to build hwloc on a cray machine with cray compiler
:/opt/cray/craype/2.5.4/bin/cc
I get the following error :
$> CC=cc ./configure --prefix=$PWD-cc-install
$> make
Making all in src
make[1]: Entering directory `/home/j0306818/xavier/hwloc-1.11.5/src'
CC bitmap.lo
/bin/cc

Do you mean __GNUC__? And which value does it have?
In other words: what, exactly, actually gets included from that file?
:)
Yes, with no warning, and I can also execute my a.out.
$> cc toto.c
$> ./a.out
$> cat toto.c
int main(int argc, char *argv[])
{
return __builtin_ffsl((unsigned long) argc);
}
