Cmake question

[zarzor2010]

Hi All,
I have a problem with cache variables in cmake.

I want to check the combiler for a certain flag -C99 flag. So, I used the following statement
CHECK_C_COMPILER_FLAG("-C99" FLAG_OK)

The problem is that we I ran cmake for the first time it said that c99 is not found and set the FLAG_OK variable in CMakeCache.txt to 0.

Now, I fixed the problem =in the compiler to make it support -C99. But cmake doesnot check the flag any more and just keep saying not found. This is becuase the FLAG_OK is already equals to 0 in cache file.

Is there any way to delete the cahce variable. or force cmake to check for the flag every time I run it?

Thanks for your help

There should be a CMake cache file somewhere in your output directory. Try messing with it!

Thank you so much for your reply.

I tried deleteing the cmake.cache file and it worked fine. But if another user who is not experienced with cmake and tried to compile the code it wount work.

even if he fixed the problem, cmake will tell him to fix the -C99 flag.

So, is there any way to make it automated for normal users.?

Thanks
