[Ctk-developers] mingw build failure

Sun Aug 22 17:50:02 EDT 2010

Hi Dean,

commit 
http://github.com/commontk/CTK/commit/713b8883a9a4ec6c38d093367e99c13eb4d7a6ab 
will fix your QtMobility build issue. With commit 
http://github.com/commontk/CTK/commit/e87fe1533d06a96e0fd0df0a19635573cd6b5981 
the CTK compiler flags will also work on MinGW systems.

You will still get unresolved references during linking of CTKCore (in 
Log4Qt) which probably is due to a wrong linking order (Log4Qt is a 
static library, listed at the end of the linker command line). I will 
try and fix it in the next week.

Best,
Sascha
