Toolchain fails to compile on Debian buster: "glob.c:(.text+0x8fb): undefined reference to `__alloca'"

  • when i try to build for x86_64 on debain buster the build fails right at the beginning with the following error:

    can this have sth. to do with the (recently updated) gcc-version? about a month ago everything used to compile.

    Code
    ice@rice:~/le/LibreELEC.tv$ gcc -v

    as a (dirty) workaround i built the first part on linux mint 18.3 , then compiles almost to the end up to this quemu-error on this debian release.

    any idea/workaround?

    THX for your input!

    thx, i will try this as soon as i'm back at this machine again.

    meanwhile i got everything to compile on debian stretch with one little adjustment: in

    Code
    build.LibreELEC-Generic.x86_64-9.0-devel/xorg-server-1.19.6/glx/glxscreens.c

    i had to delete line 46.

    it compiled, but i haven't tested the resulting build yet.
