It's not impossible at all, clang, gcc and icc use a common C++ ABI
and should be link-compatible
Well my experience says that this does not work with gcc and solstudio.
You've picked the wrong person to complain about C++ too so let's
No I don't complain to you but I complained through your message :-)
ignore that ... you didn't say whether you looked at the libstdc++.so
libs in /opt/gcc-4.6.0 and whether any of them use ELF symbol
versioning, which might make them incompatible.
I have compiled Qt with gcc 4.5.3 and 4.6.0 and now I am trying again
with 4.6.0 that has been configured to use GNU ld and GNU as. As about
the versioning thing I am not sure what you mean, bur I hope the
following help:
