[M3devel] [cm3] [partially-solved] unresolved pthread symbols during bootstrap

[Ronny Forberger]

Hi,

the pthread symbol problem has solved for me. I was using development
version of cm3. Now having checked out release_cm3_5_4_0 the symbols
weren't needed, not even it was necessary to add PTHREAD to any array in
cm3.cfg.

But I now getting another issue:

Though the build process successfully went though the

    ./do-cm3-core.sh buildship
    ./install-cm3-compiler.sh upgrade
    ./do-cm3-std.sh buildship

commands, I can't see m3build binary having been built or installed.

The documentation couldn't give me any answer on here as well.

Have you got ideas again ?

Thank you.

Ronny
