Does MongoDB require the gcc version 4.0.0 or higher? - mongodb

Question

I am using MongoDB Solaris package. When I use ldd command to check the mongod, the output is:
bash-3.2# ldd mongod
libsocket.so.1 => /lib/64/libsocket.so.1
libresolv.so.2 => /lib/64/libresolv.so.2
librt.so.1 => /lib/64/librt.so.1
libnsl.so.1 => /lib/64/libnsl.so.1
libstdc++.so.6 => /usr/sfw/lib/amd64/libstdc++.so.6
libm.so.2 => /lib/64/libm.so.2
libgcc_s.so.1 => /usr/sfw/lib/amd64/libgcc_s.so.1
libgcc_s.so.1 (GCC_4.0.0) => (version not found)
libpthread.so.1 => /lib/64/libpthread.so.1
libc.so.1 => /lib/64/libc.so.1
libaio.so.1 => /lib/64/libaio.so.1
libmd.so.1 => /lib/64/libmd.so.1
libmp.so.2 => /lib/64/libmp.so.2
libscf.so.1 => /lib/64/libscf.so.1
libdoor.so.1 => /lib/64/libdoor.so.1
libuutil.so.1 => /lib/64/libuutil.so.1
libgen.so.1 => /lib/64/libgen.so.1
From the output, I notice the following lines:
libgcc_s.so.1 => /usr/sfw/lib/amd64/libgcc_s.so.1
libgcc_s.so.1 (GCC_4.0.0) => (version not found)
Per my understanding, I think it means the version of libgcc_s.so.1 must be 4.0.0 or higher. Does MongoDB require the gcc version be 4.0.0 or higher? I can't find this requirement in its website.

Yes.
From the source code on Github, we can see:
#if __GNUC__ < 4
#error gcc < 4 not supported
#endif
https://github.com/mongodb/mongo/blob/master/src/mongo/pch.cpp
I can't find this in the official docs though, but the docs do state that you need GNU C++ Toolchain, which I would imagine implies whatever is the most current release.
