[CMake] CMAKE 2.8.5 - CMAKE_GENERATOR Bug?

Mon Feb 6 00:45:37 EST 2012

Hello Everyone

http://www.cmake.org/Bug/view.php?id=12936

I have uploaded a "repro" case here.  Should be reproducible in a matter of 1 minute.
I am interested to see if any of you could reproduce the bug.
Windows 7 64-bit is what I use here to reproduce the issue with CMAKE 2.8.7

I have not uploaded the workaround though.
The workaround is very simple. One just needs to manually invoke "cmake" through a custom configure and build script.

Thanks,
Best Regards,
Sarnath

Hi Sarnath,

Could you create an issue in the tracked where you will describe the problem, the work around and also attach the configure.bat file ?

I am sure that will be helpful in solving the problem.

If there is already an issue .. could you mention the corresponding # number ?

Thanks for your help

Hello,

I managed to find a workaround.

Instead of allowing CMAKE to work out the configuration and build of the  external CMAKE project,
I just wrote a batch file (configure.bat) which would invoke "cmake" internally to generate the makefiles.
After that, I could use "cmake --build" command to build the external project.

With these workarounds, I was able to generate a 32-bit tool alongside 64-bit executables and 64-bit libraries.

Sigh of relief!! But CMAKE authors would want to look into this issue,

Thanks,
Best Regards,
Sarnath

Hello John,

I can +vely see this behavior with the latest 2.8.7 version as well.
I am using a windows 64-bit machine with Visual studio 2008 installed on it.

This is how I use Externa Project Add command:
"
   include(ExternalProject)
   ExternalProject_Add(
       gen
       CMAKE_GENERATOR "Visual Studio 9 2008"
       URL file://${CMAKE_SOURCE_DIR}/src/tools/gen
       INSTALL_COMMAND ""
   )
"

The CMakeLists.txt hosting this ExternalProject_Add is generated using "NMake Makefiles" - which uses the default 64-bit build configuration.
A verbose Makefile generation nails the issue.
The "gen" project is generated as <cmake "-G Visual Studio 9 2008"> which screws things up.

Can somebody please help me with this?

Thanks,
Best Regards,
Sarnath

I am not seeing this breakage. However you are 2 versions behind in cmake.
