I try to cross compile gcc 14.1.0 for an older arm linux.
During compilation it fails with a long list of linking problems for
libstdc++.so
I configured gcc with:
../configure --prefix=/opt/armv7_$(GCC_VERSION) --enable-languages=c,c++
--with-sysroot=/opt/podman_debian8/merged --enable-multiarch
--with-fpu=vfpv3-d16 --with-mode=thumb --with-arch=armv7-a
--target=arm-linux-gnueabihf --disable-multilib --with-stdc++lib=static
Is it possible to add/remove some flags for ./configure to get the new
compiler to work even with the libm.a library from the target system
which was not compiled with fPic.
I don't know if this could work. I certainly don't think I've ever tried it before, but it's really beyond my sphere of expertise. If you're building a shared libstdc++ that links against a static libm, I certainly don't think you want to be pulling the symbols from libm into your shared library (that would cause it to export symbols that should be in libm itself).
I also wondered that the build tries this. But my question still is: How
to configure to get a compiler with needed libs working for the given
environment. I still sitting in the dark :-)
