I wonder what would happen if you put it in the '[toolchain]' section of ~/.buildman ?
buildman --list-tool-chains cannot detect the toolchain if doing so.
No, it works by looking for filenames rather than running the command line. But that should not affect operation.
The path in ./.buildman is partial. buildman appends other stuff to make a complete path. I need to put double quote for "distcc <my path prefix>". I don't see how that could work.
It doesn't have to - if you give a complete path then it will use it. You might need to change things in toolchain.py to make it work. See MakeEnvironment() which sets up the environment for Make - CROSS_COMPILE, PATH.
Yes, one problem is that buildman uses objsize to find out the code/data size. How can that work with distcc?
Probably it won't.
I wonder how the build copes with things like 'objcopy' then, which are in the Makefile.
If not using buildman, I can modify Makefile to prefix distcc to CC and keep using MAKEALL.
Indeed. I wonder why that doesn't work with buildman?
Doesn't buildman checkout each commit? Modifying the Makefile doesn't survive a checkout.
Well if you are using that feature out certainly can't use MAKEALL since it doesn't support it. If you leave off the branch (-b) buildman will build the current source and not check anything out.
I like to use buildman to build all the commits.
Can I force CC with buildman?
If you add that feature you can. But maybe you just need to force CROSS_COMPILE?
