I caught error with crossdev

[Dawn_Xu]

I tried every arch and libc, but when compiling stage1 gcc, It said
"mv: cannot stat '/var/tmp/portage/cross-riscv64-linux-musl/gcc-13.2.1_p20240210/image/usr/lib64/libcc1*': No such file or directory"
or others in same error
so how to solve this?

Dawn_Xu,

I was able reproduce the same error in your post.

This is problem crossdev incompleteness, It just does not support riscv64's gcc structure. And the main problem lie on gcc installed in usr/lib whereas the emerge want to get it from usr/lib64

There are two workarounds I tested,

• Manully quick modify /etc/portage/env/cross-riscv64-linux-musl/gcc.conf -- change the line LIBDIR_lp64d='lib64' to LIBDIR_lp64d='lib'. You have to do quick enough before gcc start compile. because those env files are generated on the fly by crossdev.
  
• Use Ebuild Phase Function Hooks -- by creating a /etc/portage/bashrc with

  Code:

  pre_src_install() {   echo "Enter pre_src_install"   if [ "$PN" = "gcc" ]; then     echo "set LIBDIR_lp64d=lib"     LIBDIR_lp64d='lib'   fi }

  
  

I build my test on LicheePi4 in a gentoo docker container using gentoo/portage:20240503. No special setup, just start the container, build crossdev then use the command
