Resolution: Works for me
Status: newclosed

My suspicion is that /Users/myusername/Documents/mythtv/.osx-packager/build/lib/libmythavformat.dylib is a bad file - either empty, or PPC. Try this:

file /Users/myusername/Documents/mythtv/.osx-packager/build/lib/libmythavformat.dylib

and report back what it says? It should say:

% file /Users/myusername/Documents/mythtv/.osx-packager/build/lib/libmythavformat.dylib
/Users/myusername/Documents/mythtv/.osx-packager/build/lib/libmythavformat.dylib: Mach-O dynamically linked shared library i386


A purge of all the built .dylibs, or a osx-packager.pl --clean, might be in order. The former would be:

find src/mythtv -name \*.dylib -delete

I tried all, but the file is not there. It gets not copied/installed. I have Xcode 4 installed, could this be the problem. 1 month before i could compile all. I have attached a config.mak, could you compare it with yours?

After editing the build paths to be the same, most of the diffs are due to backend vs frontend, Core Duo vs Core 2 Duo, and GIT head vs 0.24? I still use XCode 3.2.4, but any compiler differences should be very minor.
I think the only way for me to work this out is to do a -distclean, and then attach a full build log. e.g.:

osx-packager.pl --distclean
osx-packager.pl --verbose | tee fullbuild.txt

Got it to compile.

Here is what I did..

ran : ./git/packaging/OSX/build/osx-packager.pl -debug -srcdir=/Users/jeanyves_avenard/Work/mythtv/git -force -verbose -m32

this failed with the error above. Went into the folder: .osx-packager/src/myth-git/mythtv ran the command: find . -name "libmyth*.dylib" -exec cp {} ~/Work/mythtv/.osx-packager/build/lib/ \; -print to install the .dylib files in the build folder

Edited the osx-packager.pl script and commented line 777:

#&Syscall([ '/bin/rm', @mythlibs ]) or die;

so it wouldn't delete the libmyth file from the build directory

Re-ran osx-packager.pl with -noclean -nohead

Peter, thanks for fullbuild.txt. As Jean-Yves has hinted, it is some sort of sequencing problem.
FFmpeg makes these libraries:

LD      libavutil/libmythavutil.50.dylib
LD      libavcore/libmythavcore.0.dylib
LD      libavcodec/libmythavcodec.52.dylib
LD      libavformat/libmythavformat.52.dylib
LD      libswscale/libmythswscale.0.dylib
LD      libpostproc/libmythpostproc.51.dylib
LD      libavdevice/libmythavdevice.52.dylib
LD      libavfilter/libmythavfilter.1.dylib

but not the install lib file names that MythTV expects (i.e. there is no libmythavformat.dylib in ../../external/FFmpeg/libav*). If I turn FFmpeg verbose building on:

% git diff Makefile
diff --git a/mythtv/Makefile b/mythtv/Makefile
index 4de0ae1..cf7ae49 100644
--- a/mythtv/Makefile
+++ b/mythtv/Makefile
@@ -61,7 +61,7 @@ $(addsuffix /Makefile,$(QT_SUBDIRS)): %/Makefile :
        cd $*; $(QMAKE) QMAKE=$(QMAKE) -o $(@F) $(<F)
 
 $(SUBDIRS): $(addsuffix /Makefile,$(SUBDIRS)) libs/libmythbase/version.h
-       $(MAKE) -C $@
+       $(MAKE) -C $@ V=YES  # Verbose building
 
 $(addsuffix _clean,$(SUBDIRS)): $(addsuffix /Makefile,$(SUBDIRS))
        $(MAKE) -C $(subst _clean,,$@) clean

then it both creates the dylibs, and creates the links for me:

% ./osx-packager.pl --enable-backend --verbose
...
cd ./libavcodec/ && ln -sf libmythavcodec.52.dylib libmythavcodec.dylib
gcc -dynamiclib -Wl,-single_module -Wl,-install_name,/Volumes/Backups/MythTV/.osx-packager/build/lib/libmythavformat.dylib...
...
cd ./libavformat/ && ln -sf libmythavformat.52.dylib libmythavformat.dylib

so I am still at a loss. Perhaps make that same verbose mod and attach a fresh fullbuild.txt?

Nigel. libmythavformat and other libmythav* are present for me in the external/FFmpeg/libav* folder. That's not the problem

The issue is that when linking the main apps, it is trying to link against libmythavformat in the .osx-packager/build/lib directory rather than the one in externel/FFmpeg. This libraries haven't been copied to build/lib yet at this point of the compilation.

Once you've successfully built once, and provided you do not delete libmyth* in build/lib ; then everything works okay.

comment:8 Changed 13 years ago by nigel@…

Not sure about apps - the errors I have seen for for filters/kerneldeint?
For you guys, linking the filters seems to be using something that refers to */.osx-packager/build/lib, but as far as I can tell, that shouldn't happen. My HEAD .pro/Makefiles on 10.6.5 Core Duo do this:

% cd src/mythtv/filters/kerneldeint               
% rm -f ../../../../../build/lib/libmyth*
% rm *.dylib
% make
rm -f libkerneldeint.dylib
ccache g++ -headerpad_max_install_names -arch i386 -single_module -dynamiclib -o libkerneldeint.dylib filter_kerneldeint.o    -L../../external/FFmpeg/libavcodec -lmythavcodec -L../../external/FFmpeg/libavcore -lmythavcore -L../../external/FFmpeg/libavutil -lmythavutil -lmyth-0.24 -L../../libs/libmyth -lmythbase-0.24 -L../../libs/libmythbase -lmythui-0.24 -L../../libs/libmythui -lmythupnp-0.24 -L../../libs/libmythupnp
%

i.e. no refs to the installed library directory there. Perhaps something in your environments?

I have attached a litte shell script. With this the build works, but's a hack.

comment:10 Changed 13 years ago by Nigel

OK. I still don't know why it is only a problem on 10.5, but on 10.6 if I do a distclean and then half a full build (i.e. control-C after it has created FFmpeg + myth libs) and examine the libs:

% cd src/mythtv
% find . -name \*.dylib -exec otool -L {} \;
./external/FFmpeg/libavcodec/libmythavcodec.52.dylib:
	/Volumes/Backups/MythTV/.osx-packager/build/lib/libmythavcodec.dylib (compatibility version 52.0.0, current version 52.86.1)

ls: /Volumes/Backups/MythTV/.osx-packager/build/lib/libmythavcodec.dylib: No such file or directory

it reveals the problem. The FFmpeg libraries have references to the future install path!
Their makefiles use stuff like:

-install_name,/Volumes/Backups/MythTV/.osx-packager/build/lib/libmythavcore.dylib

which I think is causing the problem. Fixes? 1) change our top-level makefile to make and install FFmpeg before making everything else, or 2) change configure:

% git diff configure
diff --git a/mythtv/configure b/mythtv/configure
index 44d8c0b..d7b9beb 100755

Can a few others check that fixes the 10.5 link problem?

Can you send me diff as file? in the ticket seem to get something lost.
