Hello, Please CC as I'm not subscribed. Hope line breaks are ok, I hate Lotus Notes :) I'm having a lot of trouble getting gcc 4.2.1 compiled and run on AIX 5.3 on the power5 architecture. Even after GCC compiles successfully it seems libstdc++.a isn't built correctly. We have the IBM binary gcc-4.0.0 compiler installed in /opt/freeware/bin so I know its possible to get GCC on here somehow. It builds fine but compilation of this simple test program fails with g++. gcc SEEMS to function ok but I havent checked it in depth yet. Take a look at the session below (edited for readability + mask user+hostname only) where it first fails to find libgcc_s even though the configure script placed it in /sys/usr/lib just like I asked, Next it cant link against libstdc++.a. Once I turn on the verbose output I see that libstdc++.a has no symbols being imported! I dont know much about compilers but it seems that I need SOME symbols from libstdc++ are needed. Last, if I force it to link against IBM's libstdc++.a it works fine. Am I building gcc wrong? I did build it with GNU make and the AIX as+ld. I borrowed IBM's config flags from 4.0.0. Any additional info needed? ============================================================ user@host:~/tmp/gcc$ cat hello.c #include <cstdio> int main(int argc, char *argv[]) { printf("Hello, world!\n"); return(0); } ============================================================ user@host:~/tmp/gcc$ g++ -o hello hello.c ld: 0706-006 Cannot find or open library file: -l gcc_s ld:open(): No such file or directory ld: 0706-006 Cannot find or open library file: -l gcc_s ld:open(): No such file or directory collect2: ld returned 255 exit status ============================================================ user@host:~/tmp/gcc$ g++ -o hello hello.c -L/sys/usr/lib ld: 0711-317 ERROR: Undefined symbol: __gxx_personality_v0 ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. collect2: ld returned 8 exit status user@host:~/tmp/gcc$ g++ -v -o hello hello.c -L/sys/usr/lib -Wl,-bnoquiet Using built-in specs.
