Dear edk2-devel subscribers,
A few moments ago, I have published a patch to the EDK2 BaseTools with the
subject "BaseTools: Add Multiple Workspaces support for custom Makefiles.",
which is aimed at providing Custom Makefile modules support for Multiple
Workspaces. Writing the patch, I noticed that in quite a few areas WORKSPACE is
still used (especially in MODULE_DIR, which is the reason custom Makefile
modules would not be buildable in a different workspace from the primary). In
the places in which it isn't, mws.join() is called to construct a path by also
checking the PACKAGES_PATH list.
To simplify the process and ending with cleaner code, I propose to have the
PLATFORM_DIR variable fixed to point to the correct, absolute path and
construct other variables (such as MODULE_DIR) from that value, so PLATFORM_DIR
serves as a central variable (changes to it affect all paths = easier to
maintain).
Sadly, I do not think I either have the Python skills, or the insight in the
inner workings of BaseTools to implement such a patch. I would be grateful if
someone would look into implementing this, or a similar behavior to fully
support Multiple Workspaces and have an easier to maintain codebase.
Regards,
Marvin.
