_FORTIFY_SOURCE seems to break compilation

[tammela]

Compiling with _FORTIFY_SOURCE, which might standard in some distros, seems to break the compilation process with an error on libc's function vnsprintf().

The following patch can fix the compilation:

-set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS} -Wall")
-set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -O3")
+set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS} -U_FORTIFY_SOURCE -Wall")
+set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -U_FORTIFY_SOURCE -O3")

Might need more info as alpine uses musl.

Setup: Alpine 39 gcc (Alpine 8.3.0) 8.3.0

i want to look on this issue. Is this error arose after addition of libraries to make work on all platform?

[tammela]

No.

Just do a build on a alpine virtual machine and it shall reproduce the issue.

Thanks, Pedro
