Detect glob_pattern_p()
|
|
|
|
The current popt build system tests the existence of <glob.h>, and
|
|
then assumes that if __GLIBC__ is defined, then glob_pattern_p() must
|
|
be available. Unfortunately, that's not true with uClibc: <glob.h> may
|
|
be installed, but not necessarily the GNU glob extensions... and
|
|
uClibc defines __GLIBC__. This is causing build issues with certain
|
|
uClibc toolchains that do not have GNU glob extensions enabled.
|
|
|
|
To fix this, this patch adds an AC_CHECK_FUNCS() test for
|
|
glob_pattern_p, and uses that to find out whether glob_pattern_p() is
|
|
available or not.
