I have a rather basic problem with compiling a simple C++ program, or rather
with the final linking using collect2. This is the call made:
/opt/experimental/bin/gcc -v -O2 -o CPPTest ../CPPTest.cpp ../CPPTestMain.cpp
The following is the verbose output for the final collect2 stage:
/opt/experimental/lib/gcc-lib/i486-suse-linux/3.0.1/collect2 -m elf_i386
-dynamic-linker /lib/ld-linux.so.2 -o CPPTest /usr/lib/crt1.o /usr/lib/crti.o
/opt/experimental/lib/gcc-lib/i486-suse-linux/3.0.1/crtbegin.o
-L/opt/experimental/lib/gcc-lib/i486-suse-linux/3.0.1
-L/opt/experimental/lib/gcc-lib/i486-suse-linux/3.0.1/../../..
/tmp/cc3xAK5D.o /tmp/ccq0irtE.o -lgcc -lc -lgcc
/opt/experimental/lib/gcc-lib/i486-suse-linux/3.0.1/crtend.o /usr/lib/crtn.o
/tmp/ccq0irtE.o: In function `__FRAME_BEGIN__':
/tmp/ccq0irtE.o(.eh_frame+0x12): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status
As you see this is with SuSE7.3 LInux gcc 3.0.1 'experimental' build - but I
get the same problem with a cygwin compiled gcc 3.1 on Win9X.
The problem occurs with the most minimal C++ class so I presume it's
something fundamental I'm doing wrong!
(It always worked with gcc 2.95.x)
