在挂载目录上运行时cmake错误

Question

I have issue running cmake on a package residing in a mounted folder. I have full permissions on this mounted folder.

CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:50 (MESSAGE):
The C compiler "/usr/bin/gcc" is not able to compile a simple test program.

It fails with the following output:

Cmake seems to run fine when I copy the package on to my linux filesystem.

Thanks, Gudge

Answer 1

According to this link , the error Value too large for defined data type has to do with gcc executing stat() on Samba-mounted file systems. The inode returned is apparently rather large for those file systems.

The solution is to ensure your mount command has nounix,noserverino in the options column (in /etc/fstab or equivalent).

See the mount.cifs man page for further details.

Answer 2

This problem with mounted folders can also manifest itself with a failure for the cmake command " file(GLOB VAR PATTERNS) " to find anything. In my case, the subsequent command " add_library " would end up with no source files and fail with the following error:

You have called ADD_LIBRARY for library ... without any source files. This typically indicates a problem with your CMakeLists.txt file.

I hope that by mentioning this here that it will cut the search time of others from 4 to 2 minutes.
