"unknown type name ‘intmax_t’" issue

[DavidPeicho]

I had exactly the same problem, when installing the library on Ubuntu 16.10, using CMake.
In order to fix it, I added myself the stdint.h include and it fixed the problem. I do not know why the check_type_size did not complain when using cmake.

Can you let me know:

• the version of Check you are attempting
• the OS you are building on and the compiler
• the output of "cmake ." before attempting to build

I am on linux mint 17.3; I run apt-get install check and it installed the v0.9.10 version

The output of cmake .. (I am in the build folder):

-- The C compiler identification is GNU 4.8.5
-- The CXX compiler identification is GNU 4.8.5

Looking at the CMake configuration for the example project, there is the following section which is likely relevant:

# Check for integer types
# (The following are used in check.h. Regardless if they are used in
# the project, they will need to be checked in order to use Check).
check_type_size(intmax_t INTMAX_T)
check_type_size(uintmax_t UINTMAX_T)

The check.h header should be pulling in the stdint.h header if it exists, which should define intmax_t and uintmax_t. Can you attempt to add the CMake checks mentioned above and see if it discovers something off about intmax_t on the system?
