g++ 3.3 and AIX

[Peter Keller]

Hello,

Is there any way that I can force a static linking of libstdc++.a into a
binary produced by g++ 3.3 on AIX 5.1?

Even if I put the libstdc++.a file directly on the command line, it still ends
up linking it dynamically. If I use -bnso, then ALL libraries are linked
statically, but I don't want libc.a linked statically into the executable,
only libstdc++.a.

Any ideas on how to fix it? Thanks.

Try "... -bstatic -lstdc++ -bdynamic ..." as long as g++ maintains
command line ordering when it calls the linker.

I thought -b was for choosing a target machine when you have a compiler
that can compile for multiple architectures. -B(in case this is what you
meant to say) is for fixing the search paths for things like ld and cpp.

I think you meant: -Bstatic and -Bdynamic supplied to the _GNU Linker_.
Trouble is, I'm not using the GNU linker for this phase of the link.
I'm using collect2 under gcc which uses the AIX linker, which doesn't
understand -Bstatic and -Bdynamic in the capacity I need it.

I found -bnso and -bso for the AIX linker, but it seems all or nothing.

Is there anyway I can ask for SOME .a files(which contain .so files) to be
statically brought in, but leave other libraries shared. Basically
the -Bstatic/-Bdynamic effect for the AIX linker?

Thanks.

My mistake. You are correct.

If my command line looks like this:

AIX aix-machine > /usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/collect2
-bpT:0x10000000 -bpD:0x20000000 -btextro -bnodelcsect
/lib/crt0.o -L/usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3
-L/usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/../../.. foo.o
-bstatic -lstdc++ -bdynamic -lm
/usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/libgcc.a
/usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/libgcc_eh.a
-lc /usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/libgcc.a
/usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/libgcc_eh.a -m

then it works as expected. I didn't know that -bstatic and -bdynamic were
valid flags for the AIX linker. But now, after careful reading of the man
page, I see what you are talking about. I've tried it and it works.

Thank you VERY much.

Well, it is what I do :-)

Happy to assist.
