In boilerplate function 'get_program_name', basename is used.
When libgen.h is incuded in your program, the basename gets the POSIX
version (no const char*, see 'man basename'):
char *basename(char *path);
This results in the following compiler warning:
boilerplate/setup.h: In function 'const char* get_program_name()':
boilerplate/setup.h:107: error: invalid conversion from 'const char*' to 'char*'
boilerplate/setup.h:107: error: initializing argument 1 of 'char*
__xpg_basename(char*)'
Test application:
#include <libgen.h>
#include <psos/psos.h>
int main(int argc, char * const argv[])
{
return 0;
}
When the libgen.h is not included, the warning is not seen.
This patch solve the above issue creating a string on the stack instead of
a constant string.
