Doing minimal linux system setup with mkroot and trying to create a minimal environment with a native toolchain to run autoconf in. This would mean getting the native static toolchain for my architecture from https://landley.net/toybox/downloads/binaries/toolchains/latest/. Mounting the image (Why are cross compilers tarballs while native compilers are fs images? Wouldn't making them tarballs mean that you could extract their contents without running losetup and dealing with mounting devices and needing root permissions ? I trust they were made fs images for a good reason, but... _why_). And ideally running a mkroot overlay on it because that's what the overlays seem to be made for, but...:
/sbin/cp: cannot overwrite non-directory '[Path to root/host/fs]/././lib' with directory '[Path to toolchain]//./lib' It's whining that It's trying to copy a directory to a symlink of a directory. A working but non-viable solution is to use rsync -Ka (You also need --exclude=usr when copying the native toolchain, maybe a CPFLAGS for the overlay?). But rsync is non-standard. Have you considered or ran into this problem before? Then even after that, it whines that cc1 isn't there because it didn't copy the usr/ symlink: # echo 'int main() {printf("123\n");}' | gcc -xc - gcc: fatal error: cannot execute 'cc1': execvp: No such file or directory compilation terminated. Because it's trying to exec /usr/x86_64-linux-musl/bin/cc1, which we _can't copy_ for multiple reasons. Okay, linking them manually on the host image. Now I'm able to use the compiler. The configure script for the thing I'm working with fails (something about the read builtin), but I can remedy with my host bash copying package for now. Is running a compiler under mkroot a goal, and if so why haven't you made a package for it? (I'm assuming this is a MUCH larger and more complex issue than I was originally expecting, but still something to just copy the native toolchain to the filesystem isn't hard (It is if you are doing it with raw overlays, but not if you have bash scripting at your disposal)) Is it a situation where it's a TODO item and just not ready yet? - Oliver Webb <aquahobby...@proton.me> _______________________________________________ Toybox mailing list Toybox@lists.landley.net http://lists.landley.net/listinfo.cgi/toybox-landley.net
