[gentoo-user] overnetclc: error while loading shared libraries: libstdc++.so.5: cannot open

[gentoo-user] overnetclc: error while loading shared libraries: libstdc++.so.5: cannot open

[Bo Andresen]

I am having a problem with overnet on an amd64 computer. For some reason it 
connat load libstdc++.so.5.

$ overnetclc 
overnetclc: error while loading shared libraries: libstdc++.so.5: cannot open 
shared object file: No such file or directory

I checked and realized that I did not have this file so I emerged 
libstdc++-v3. This did get me the file in /usr/lib64. Still no luck. I 
suppose the problem is that overnet is a binary package which requires a 32 
bit library. Still I don't know how to solve this problem. Perhaps the 
problem is that I need multilib but I don't know how to select that since the 
multilib use flag is missing.

Multilib is handled by profiles now.  From the part of your post I've 
trimmed (DOH) you are using a multilib profile, so the use flag is treated 
as always on.

Also, you might need one (or more) of the packages from 
app-emulation/emul-x86-*.

But shouldn't libstdc++-v3 install both 64 bit and 32 bit libraries then? It 
most certainly doesn't.

/usr/lib64/libstdc++-v3/libstdc++.so.5 -> libstdc++.so.5.0.7
/usr/lib64/libstdc++-v3/libstdc++.so.5.0.7

Also this leads me to believe that  the use flag is actually off. This may 
have no importance (because of the profile) but I am quite confused on how 
this is supposed to work.

The description leads me to believe that this is for non-multilib systems. But 
I want multilib. Am I missing anything here?

If anyone can direct me towards some proper documentation of how multilib is 
supposed to work I would appreciate that.

And as always thanks for your replies. :)

What is multilib and how can I use it?
 Every AMD64 processor is able to run 32-bit code as well as 64-bit code. 
However, when you have a 32-bit application, you are unable to mix it with 
64-bit libraries or vice versa. You can, however, natively run 32-bit 
applications if all shared libraries it needs are available as 32-bit 
objects. You can choose whether you want multilib support or not by 
selecting the according profile. The default is a multilib-enabled 
profile.

The description must be out of date with current practice; from my system 
(a multilib system):

As you can see from your own mail emul-linux-x86-compat does not install any 
libs into /usr/lib32. Therefore I still think that the description may be 
correct and that package may be unaware of multilib being enabled. 
Nonetheless it does solve the problem and that's good enough for me. :)

While this does explain that multilib is in fact enabled it tells me nothing 
about how it is supposed to work. Just above it [1] there is a section about 
the emul-linux-x86 packages which apparently explains that 
emul-linux-x86-compat should have been a dependency of overnet. But it does 
not state anything about multilib being required for those emul-linux-x86 
packages to work. And if multilib isn't required for it then I am uncertain 
about what good it actually does.

Yep, those packages don't work under a no-multilib profile.
