Support mingw toolchain
-----------------------
Key: MOJO-1109
URL: http://jira.codehaus.org/browse/MOJO-1109
Project: Mojo
Issue Type: New Feature
Components: native
Environment: Gentoo Linux
Reporter: Martin von Gagern
Attachments: generic-windmc-windres.patch
I would very much like to have a mingw toolchain, so that I can cross-compile
Windows applications on Linux.
For that I would need several things:
1. compiler and liker like generic, but with mingw32-gcc as executable.
This can be done in the pom by specifying all the executable names, but that is
rather tedious.
You might consider a more general approach to cross compilers, making target
architecture a pom element, and configuring the comoilers appropriately. Would
require major surgery, I guess, but might be worthwhile in terms of portability.
2. mingw32-windmc as resource compiler.
The interface seems to be pretty much that of the msvc mc, so this can again be
achieved in the pom. If you introduce a new provider for other components, it
would seem reasonable to provide the resource compiler as well.
3. mingw32-windres as message compiler.
The command line syntax is a bit different from msvc, using -I for include
directories and -o for output file. So far things can be changed by providing a
new component. Compiler works well enough, but the gcc linker won't accept the
.res file it generated. Instead, mingw-windres usually generates object files.
As the file extension "res" seems to be hardcoded into the
ResourceCompilerConfiguration, this would require a change to the API.
I'll attach a patch for 2. and 3., although I couldn't test it here, because
the api tests fail even without any modifications, in maven-native-1.0-alpha-2
as well as in current trunk. I'll try to inverstigate these build errors
tomorrow, and update my patch if required.
For the cross compiling issue, 1., I'd like a few more comments before I start
coding.
