[Scons-users] CheckFunc doesn't give correct result due to "error: too few arguments to function"

[Alex Fan]

Hi, Happy New Year

Reproducer:

env = Environment()
conf = Configure(env)
conf.CheckFunc(
            'getxattr',
            header=
                '#include <sys/types.h>\n#include <sys/xattr.h>'
        )

It produces a config.log like:

...
gcc -o .sconf_temp/conftest_c10cc6ce1defa319be0b1e0d1eeface9_0.o -c .sconf_temp/conftest_c10cc6ce1defa319be0b1e0d1eeface9_0.c

   15 |   getxattr();
      |   ^~~~~~~~

   60 | extern ssize_t getxattr (const char *__path, const char *__name,
      |                ^~~~~~~~
scons: Configure: no


My gcc version is gcc version 11.3.1 20221209 (Gentoo 11.3.1_p20221209 p3)

Any clue if this can be fixed?
