Hi Guix,
the configure flags defined in “cross-gcc-arguments” disabled the C++
compiler to prevent an error that happens when building libstdc++-v3.
Since I needed a C++ cross-compiler for ARM I added “c++” to the list of
enabled languages and added the configure flag
“--disable-libstdc++-v3”. This is now the same as what is done in
“gcc-boot0” in “commencement.scm”.
Will this cause a rebuild of every package on ARM? Is it okay to push
this to core-updates?
~~ Ricardo
