I am Following this tutorial to cross compile a Qt app for RPi 4:
https://github.com/alexandraB99/embedded_development_Qt_course_aux?tab=readme-ov-file
I started building the toolchain.
- Using ubuntu 20.04:
- Installed binutils 2.31 with following :
../../src/binutils-2.31/configure --target=${TARGET}
--prefix=${PREFIX}--with-arch=armv8-a --with-fpu=vfp --with-float=hard
--disable-multilib
make -j6
make install // no errors
then building gcc for raspberry pi 4 :
Download gcc-8.3.0
contrib/download_prerequisites
../../src/gcc-8.3.0/configure --prefix=${PREFIX} --target=${TARGET}
--with-sysroot=${SYSROOT} --enable-languages=c,c++ --disable-multilib
--enable-multiarch --with-arch=armv8-a --with-fpu=vfp --with-float=hard
make -j6
Compilation error :

somehow /home/sofiane/rpi0/toolchain/build/gcc2/./gcc/as is called I don't know
why.
I added the lib path to gmp, mpc and mpfr libs, LD_LIBRARY_PATH :
/home/sofiane/rpi0/toolchain/toolchain/lib:/lib:/home/sofiane/rpi0/sysroot/usr/lib/aarch64-linux-gnu::/usr/local/qt6/lib/
/home/sofiane/rpi0/sysroot/usr/lib/aarch64-linux-gnu contains the gmp, mpc and
mpfr libs :
libmpcdec.so.6 libmpcdec.so.6.1.0 libmpc.so.3 libmpc.so.3.2.0
libmpfr.so.6 libmpfr.so.6.1.0
libgmp.so.10 libgmp.so.10.4.1
I spent two days trying to figure out the source of the problem, I'm stuck.
