Agreed to a certain degree. Using gyp/whatever to generate qmake
files, to generate Makefile/Xcode files etc seems akward to me as well.
What we really need to resolve is adding/removing files from
compilation, that's the most common
task that has to be done in 5+ build systems at the moment. So I have
a new proposal:
1) Maintain a list of headers/source files to be compiled for ALL
platforms (ie. dom/Node.cpp, etc..)
2) Keep all existing Makefile.am, WebCore.pro etc files as
"templates", ie. WebCore.pro.template, with a special
variable somewhere marking the $$HEADER_LIST$$ and the $
3) Use a script that generates individual build files (eg.
WebCore.pro) from WebCore.pro.template, it only
needs to insert the file list with the correct syntax in the
4) Keep all platform specific files to be compiled in the individual
build system files (eg. WebCore.pro.template)
I think we'll never find a consensus on a single build system, there
are too many different needs. I only care
about the most repetitive work in order to keep the build system
up2date: adding/removing cross-platform files.
Of course this is some kind of meta-meta build system, but we could
also agree to move the "template" files in a WebCore/build-templates
folder and run a "update-project-files" script after adding/remove
files, that generates the build files, like WebCore.pro and commit them.
This way only the person who added/removed a file from build would
need to run that script, instead of every one, this would effectively
hide the "meta-meta" build system.
If we find an acceptable solution for just adding/removing cross-
platform buildable files that it would already make me happy :-)
Looking for comments!
