Hi,
I noticed that a cross-compiler produces an unusable libstdc++.so
that contains an unresolved reference to aligned_alloc instead of
posix_memalign, or whatever is actually available.
Therefore it is impossible to link any C++ programs against the
libstdc++.so that comes with the cross-compiler.
That happens for instance in the following configuration:
--target=arm-linux-gnueabihf.
How could this be unnoticed so far?
I did wonder that.
The newlib config is hardcoded, which probably covers a lot of the
cross builds in regular use.
The config mentioned by Bernd (arm-linux-gnueabihf) does not use newlib.
I checked my libstdc++.log files, there's no -static option in use, I don't
use --disable-shared, so I'm not sure why there's a problem?
