Changeset 8729 for code/trunk/cmake/tools/TargetUtilities.cmake

Timestamp:

Jul 4, 2011, 2:47:44 AM (13 years ago)

Author:

Message:

Merged unity_build branch back to trunk.

Features:

• Implemented fully automatic build units to speed up compilation if requested
• Added DOUT macro for quick debug output
• Activated text colouring in the POSIX IOConsole
• DeclareToluaInterface is not necessary anymore

Improvements:

• Output levels now change appropriately when switch back and forth from dev mode
• Log level for the file output is now also correct during startup
• Removed some header file dependencies in core and tools to speed up compilation

no more file for command line options

• Improved util::tribool by adapting some concepts from boost::tribool

Regressions:

• It is not possible anymore to specify command line arguments in an extra file because we've got config values for that purpose.

Location:

code/trunk

Files:

• . (modified) (1 prop)
• cmake/tools/TargetUtilities.cmake (modified) (8 diffs)
