clang 4.0.0+ can not compile version 1.4.0

[blacklion]

clang 4.0.0 or newer can not compile 1.4.0 release because it uses

add_cflag_if_supported("-Wall")
add_cflag_if_supported("-Wextra")
add_cflag_if_supported("-Werror")

in CFlags.cmake, and later add integer to string literal (in logging code), which is warning for clang. Build log is attached,

build.txt

This is the same error as build with ninja and GCC in PR #624. We need to fix this in the logging module.

[slyshykO]

we can use strrchr for extracting the base name.
Another problem is the dir separator on windows depends on compiler and cmake generator. And can be both '\' and '/' .

[xor-gate]

Yes for windows you can have multiple path separators (cygwin/mingw/native).

[slyshykO]

Is it still a bug?

[blacklion]

I've checked very last "master" (95b6e03), and it build flawlessly with clang 5.0.0 on 64-bit system.
Thank you!

[xor-gate]

Thanks all for being proactive. Probably fixed this issue by PR #648
