Could someone please explain some very basic stuff about
compiling/linking C and C++ code? For a new version of Myth, the
configure script succeeds with XCode 5 on Mtn Lion and _fails_ with
XCode 4.3 on Lion. The bit that I'm looking at just tests whether
certain libraries (faac in this case) are installed and, if so,
enables additional features in the package. The 'config.ep' file
(btw, is that a Unix/Linux standard thingy?) shows how it tried to do
the test:
BEGIN
/opt/local/var/macports/build/_Users_mytthtv_macports_mythtv-core.27_dev/mythtv-core.27/work/.tmp/mythtv_conf.xUGXlOJK.c
1 #include <stdint.h>
2 #include <faac.h>
3 long check_faacEncGetVersion(void) { return (long) faacEncGetVersion; }
4 int main(void) { return 0; }
END
/opt/local/var/macports/build/_Users_mytthtv_macports_mythtv-core.27_dev/mythtv-core.27/work/.tmp/mythtv_conf.xUGXlOJK.c
/usr/bin/clang -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64

/opt/local/var/macports/build/_Users_mytthtv_macports_mythtv-core.27_dev/mythtv-core.27/work/.tmp/mythtv_conf.CaP65ZOS.o
-lfaac -lm -lbz2 -lz
ld: library not found for -lfaac
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
ERROR: libfaac not found
faac _is_ installed:
MediaMini:~ mytthtv$ port installed |grep aac
faac @1.28_2 (active)
I actually don't know how the test _can succeed_ with XCode 5? There
is no '-L' flag to indicate that the library is under /opt/local/lib.
I must be missing something obvious. Pointers to introductory
material gratefully accepted.
