[CMake] convert variable from hex to integer

[Olaf Peter]

Hi,

for a generated version header I need to convert a given hex to an 
integer. I've wrote:

set(RELEASE_LEVEL_ALPHA	0xA)	# For internal use
set(RELEASE_LEVEL_BETA	0xB)	# For internal use
set(RELEASE_LEVEL_GAMMA	0xC)    # For release candidates
set(RELEASE_LEVEL_FINAL	0xF)	# For final release

set(VERSION_MAJOR 0)
set(VERSION_MINOR 1)
set(VERSION_MICRO 0)
set(RELEASE_LEVEL ${RELEASE_LEVEL_ALPHA})
set(RELEASE_SERIAL 0)

in CMakeLists.txt and in version.h.cmake:

     enum {
         MAJOR          = (@VERSION_MAJOR@ << 24),
         MINOR          = (@VERSION_MINOR@ << 16),
         MICRO          = (@VERSION_MICRO@ <<  8),
	RELEASE_LEVEL  = (@RELEASE_LEVEL@ <<  4),
         RELEASE_SERIAL = (@RELEASE_SERIAL@ <<  0),
         VERSION        = MAJOR | MINOR | MICRO | RELEASE_LEVEL | 
RELEASE_SERIAL
     };

which results into:

     enum {
         MAJOR          = (0 << 24),
         MINOR          = (1 << 16),
         MICRO          = (0 <<  8),
	RELEASE_LEVEL  = (0xA <<  4),
         RELEASE_SERIAL = (0 <<  0),
         VERSION        = MAJOR | MINOR | MICRO | RELEASE_LEVEL | 
RELEASE_SERIAL
     };

The 0xA doesn't compile.

Thanks,
Olaf
