lbuild force module outputPath from outside
kikass13 opened this issue · comments
Hello,
is it possible to force a the env.outbasepath of a module from the outside (when calling lbuild build or via the project.xml) ?
I could not find anything regarding that problem inside the lbuild readme, only ways to specificly add an option which could be set. In the case of pre existing modm repository + modules, this could be difficult.
Is there a way to have the lbuild generated files inside a separate dir?
Like this? lbuild --path path/to/folder build
oh ... you are right im an idiot :D
i totally misinterpreted what the --help was saying about the path option.
edit: shouldnt this be a argument within the build command instead?
when invoking scons after doing lbuild --path "build" build
scons: Reading SConscript files ...
scons: warning: Calling missing SConscript without error is deprecated.
Transition by adding must_exist=0 to SConscript calls.
Missing SConscript 'modm/SConscript'

the stuff inside the build directory builds, but failes at the end because the linker can't find main() (because my source files are not in the build dir, do i have to invoke scons in a specific way, can this be solved via lbuild instead?
You probably want to have a custom SConstruct, ie. copy the generated one to your source dir and fix the path to the modm/SConscript. It is intended to call multiple SConscripts to integrate other custom (non-lbuild) libraries/sources via SCons. But lbuild cannot help much here, since the specialization happens after the code gen phase, you need to solve this via SCons.

doesn't that just mean, that a export_path_prefix has to be propagated through to the module build-file generator after lbuild invocation? I would try looking into hacking that into lbuild because i dont like the iea of versioning my sconstruct scripts :/
I'm honestly a little bit lost on what you're trying to do, but I'm happy to review whatever you hack together.
hmm, i can try saying it in another way:
- i want this lbuild --path prefix to be present wherever the scons files are generated (this should be possible right?)
- i also want to add that path to the generated scons file, so that the sconstruct file inside my application will build whatever is in build as well ?
whaht reason is there that this path prefox (builld/whatever) is not in the generator?
well i have added my feature and will create a pull request...
it's not clean ... but it works. maybe you can give more tips on how to it more "properly"
I have changed the scons module inside modm in a way, that allows other modules to generate the SConstruct.in template inside the current working directoy and link the repositories (via name) in it to the correct build export paths.
A detailed explanation can be seen in the MR.
