Missing library symbolic link preventing compile with C++

[Javier Lopez]

Binary package hint: gcc-4.4

Hi,

System: Kubuntu 10.04 (Lucid) 64 bit
Package: gcc-4.4
Package version: 4.4.3-4ubuntu5

Problem: Compiling a C++ program with 32 bit flag (that is, -m32) fails as it cannot be linked with (allegedly) missing library lib32stdc++6. On inspection of /usr/lib32 directory we can see that the library is indeed installed, but the symbolic link libstdc++.so is missing (it should be pointing to existing symbolic link libstdc++.so.6 that in turns points to also existing file libstdc++.so.6.0.13).

Solution: Upon creation of such a link, the linking process succeeded.

Regards.

just install gcc-multilib, the lib32stdc++6 only holds the runtime files.

Hi,

Thanks for the reply.

I already had gcc-multilib installed, as I was crosscompiling (-m32 in a 64 bits environment). Pure C was fine, but C++ was lacking the aforementioned symbolic link.

Thanks anyway.

Bye!

then it's g++-multilib

Hi again,

Thanks for taking the time to answer me.

I dind't have that package installed. I deleted the hand-created link and installed g++-multilib. Still the link is missing, and I had to recreated again by hand.

Sorry if I'm targeting the wrong package, but I'm a bit lost regarding package handling. I asked for the proper package in the ubuntu-bugsquad list and was kindly pointed to the one I posted about.

Regards.

did you try to build/link after removing the symlink and installing the package?

Hi,

No, I didn't.

I have just removed (--purge) g++-multilib, deleted the hand-created link, and reinstalled g++-multilib, and the linking succeeded. No need to create any link by hand.

Thank you very much, and I am deeply sorry for having wasted your time.

Regards.
