[Linphone-developers] linphone-3.0.0: mediastreamer2/configure.ac

[Andrey G. Grozin]

Hello *,

PKG_CHECK_MODULES is first called in configure.ac inside

if test "$artsc" = "true" ; then

Comments in aclocal.m4 say

# PKG_CHECK_MODULES(VARIABLE-PREFIX, MODULES, [ACTION-IF-FOUND],
# [ACTION-IF-NOT-FOUND])
#
#
# Note that if there is a possibility the first call to
# PKG_CHECK_MODULES might not happen, you should be sure to include an
# explicit call to PKG_PROG_PKG_CONFIG in your configure.ac

As a result,

./configure --disable-artsc

fails with an error message that pkg-config is not found in the PATH 
(which is not the case).

I think it is necessary to insert

PKG_PROG_PKG_CONFIG([some-minimal-version])

(or just PKG_PROG_PKG_CONFIG() ) somewhere near the beginning of this 
configure.ac
