Re: [CMake] The else() in CMAKE_TOOLCHAIN_FILE
Hi, Daniel, I've tried this, but it doesn't work, it returns same error as before. And there are 2 lines in CMakeCache.txt: //No help, variable specified on the command line. A:BOOL=ON Best Regards, ashi On Tue, Apr 2, 2013 at 7:44 PM, Daniel Pfeifer dan...@pfeifer-mail.dewrote: http://cmake.org/cmake/help/v2.8.10/cmake.html#opt:-Dvar:typevalue What is missing in the documentation, is that no cache entry is created if the type is not given. Set A as a cache entry of type BOOL like this: $ cmake -DCMAKE_TOOLCHAIN_FILE=./config.cmake -DA:BOOL=ON . 2013/4/2 Ashi ashi08...@gmail.com I think I find something to explain this: the config.cmake(the CMAKE_TOOLCHAIN_FILE) is reloaded several times. on first-load, the A is set, but on second-load and later-load, the A is not set. I think I can get around this problem when A is kept set. However, I don't know how can I keep the value set in cmake. Could anyone give me some suggestion? Thanks!

Re: [CMake] The else() in CMAKE_TOOLCHAIN_FILE
Yeah, my current approach is exactly creating different toolchain files.

I'm not entirely sure what you're trying to do, but it seems like you would want to make A, B, and C into cache variables. That way subsequent cmake runs will use the same value... Johannes Hi, I'm thinking that one solution could be to create three (or four?) toolchain files, one for each if clause?
