My colleagues have discovered some difficulties using the Qt4 toolset
and our custom build variant.
We've created a custom build variant like this:
# define custom variant
# - without NDEBUG defined (with assert())
# - with debug-symbols
variant custom : <optimization>speed
This enables quick runs with all asserts() triggering and a minimal
backtrace. Enough to get large logfiles very quickly ;-))
I've attached a simple testcase.
The problem is that the current Qt4 toolset provides two alternatives
for "release" and "debug".
When running the testcase, I get errors like
error: No best alternative for /QtCore
next alternative: required properties: <variant>release
next alternative: required properties: <variant>debug
so it seems to be a good idea to default to "release" when using another
(full message in custom/error.txt in testcase archive).
The attached patch removes the explicit "<variant>release" from the
declaration of the release libraries.
I'd like to apply the patch to both HEAD and RC_1_34_0.
Okay to proceed ?
Trolltech disabled support for building parallelel debug and release
variants with 4.2.0rc1.
I think we have to think about the toolset in 1.35.0 or maybe
