Simon,
I have 3 different ARM toolchains installed into /usr/bin via distro
packages. How do I tell buildman which of those to use?
I had originally thought that ~/.buildman's [toolchain] section
contained CROSS_COMPILE-like values, so I tried:
[toolchain]
root: /
arm0-not-installed: arm-none-gnueabi-
arm1: arm-none-eabi-
arm2: arm-linux-gnueabihf-
arm3: arm-linux-gnueabi-
arch64: aarch64-linux-gnu-
[toolchain-alias]
arm: arm1
aarch64: aarch64
(I intended to change the "arm: arm1" line to point at arm1/2/3 based on
which I wanted to use at a particular time).
However, running "buildman --list-toolchains" and re-reading the docs
shows me that the [toolchain] values are absolute directories that
buildman searches for files named *-gcc:
- scanning path 'arm-none-gnueabi-'
- looking in 'arm-none-gnueabi-/.'
- looking in 'arm-none-gnueabi-/bin'
- looking in 'arm-none-gnueabi-/usr/bin'
If buildman finds multiple toolchains, there doesn't seem to be a way to
tell it which one to use. Am I missing something?
I suppose a solution wouuld be to move the compiler binaries into
different separate directories, and only list one of those directories
in ~/.buildman. However, I can't do that for distro-packaged toolchains
(well, I suppose I could manually mv everything all over the place, but
that's really fragile since it'd break any time the package got upgraded
or removed and re-installed).
I think it makes sense to add new syntax into ~/.buildman to specify
"don't do automagical searching, just use this CROSS_COMPILE value that
I say". Does that sound reasonable? Automagic stuff makes for great
defaults, but if it can't be overridden, it sucks when you actually know
what you want.
