This command line does not retrieve the compiler for me I need to make it:
COMPILER_INSTALL_PATH=$HOME/0day GCC_VERSION=9.3.0 make.cross
ARCH=arm64
Sorry for inconvenient.
Have you update the make.cross script by redownload it? Parameter GCC_VERSION is for old
version of make.cross.
The latest make.cross parse COMPILER=gcc-9.3.0 correctly on my side. And also set
LD_LIBRARY_PATH to find the libs.
Let me know if still have problem. Thanks.
