I don't know exactly what to make of it, but here's the difference in searching between the ct-ng g++ and the system g++ (which is only 4.4.4 on this box, not 4.5 or 4.5.1.) [tony@whisper tmp]$ cat foo.cpp #include <fenv.h> int main( int argc, char * argv [] ) { return 0; } [tony@whisper tmp]$ strace -f -tt -e open g++ -o foo foo.cpp 2>&1 | grep fenv | grep -v ENOENT [pid 13349] 00:35:01.677651 open("/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/fenv.h", O_RDONLY|O_NOCTTY) = 5 [pid 13349] 00:35:01.682285 open("/usr/include/fenv.h", O_RDONLY|O_NOCTTY) = 5 [pid 13349] 00:35:01.682768 open("/usr/include/bits/fenv.h", O_RDONLY|O_NOCTTY) = 5 [tony@whisper tmp]$ strace -f -tt -e open /opt/cross/platforms/foo/xtools/bin/powerpc-e500v2-linux-gnuspe-g++ -o foo foo.cpp 2>&1 | grep fenv | grep -v ENOENT [pid 13357] 00:35:10.575325 open("/opt/cross/platforms/foo/xtools/powerpc-e500v2-linux-gnuspe//sys-root/usr/include/fenv.h", O_RDONLY|O_NOCTTY) = 4 /opt/cross/platforms/foo/xtools/powerpc-e500v2-linux-gnuspe//sys-root/usr/include/fenv.h:36:24: fatal error: fenv.h: No such file or directory So it looks like maybe the ct-ng install is missing the fenv.h file in the first place? Hm... doesn't help that this is an "oddball" FPU (being SPE, and not a "proper" FPU...) Thanks, t. -- For unsubscribe information see http://sourceware.org/lists.html#faq
