Summary

0003478: CHECK_TYPE_SIZE doesn't work on Mac OS X

Description

SET(CMAKE_REQUIRED_INCLUDES sys/types.h)
CHECK_TYPE_SIZE("dev_t" DEV_T_SIZE)
SET(CMAKE_REQUIRED_INCLUDES)

and

SET(CMAKE_EXTRA_INCLUDE_FILES sys/types.h)
CHECK_TYPE_SIZE("dev_t" DEV_T_SIZE)
SET(CMAKE_EXTRA_INCLUDE_FILES)

both fail to get the size of dev_t on the latest released version on Mac OS X Tiger.

I tried getting the latest version of CheckTypeSize.cmake from CVS and including it in my project's own include directory. After this I was able to get the sizeof(int) but not dev_t.

Without this feature properly functioning I will be unable to use CMake for anything as it doesn't work on Mac OS X.

I can work around this by writing individual programs that determine the size of the 4 types I need and just doing "return sizeof(type)" but that's a huge annoyance and certainly no better than our current autoconf code.

The project I'm trying to port is "xar". The eXtensible ARchiver. See URL for details.

Thanks in advance!

Notes
(0004440) Bill Hoffman (manager) 2006-07-11 13:18	CMAKE_EXTRA_INCLUDE_FILES works here. Although if HAVE_SYS_TYPES_H is set to TRUE before calling this, it will include sys/types.h automatically. Look at CMakeFiles/CMakeError.log to see why it failed, it will also include a copy of the file that gets compiled.

(0004446) David Leimbach (reporter) 2006-07-11 17:53	CMakeFiles/CMakeError.log made my error clear. Thanks Bill, I think you can close this... in case I didn't just do it.
