[vlc-devel] Notes on building under MacOS-X

[Philip Edelbrock]

Hello, I built and have been playing with VLC on my Mac and ran across 
a few oddities that I thought might be helpful to report:

Checkout from SVN vlc-trunk up to date as of Dec 12.

% ./config.status -V
vlc config.status 0.8.2-svn
configured by ./configure, generated by GNU Autoconf 2.57,
   with options "'--prefix=/sw' '--enable-macosx' 
'--with-mad-tree=./libmad-0.15.1b' 
'--with-ffmpeg-tree=./ffmpeg-cvs/ffmpeg' '--disable-xvideo' 
'--disable-glx' '--enable-opengl' 
'--with-libmpeg2-tree=./mpeg2dec-0.4.1-cvs' 
'--with-dvbpsi-tree=./libdvbpsi-20041028' 'CFLAGS=-mtune=G4 -mcpu=G4 
-fast' 'CXXFLAGS=-mtune=G4 -mcpu=G4 -mtune=G4 -fast -mcpu=G4'"

One change in vlc-config on this line to add optimizations for my 
platform:

cflags_optim=" -O3 -ffast-math -funroll-loops -fast -mcpu=G4 -mtune=G4 
-falign-loops=16"


1) strange configuration warning?

configure warning:
checking net/if.h usability... no
checking net/if.h presence... yes
configure: WARNING: net/if.h: present but cannot be compiled
configure: WARNING: net/if.h: check for missing prerequisite headers?
configure: WARNING: net/if.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to bug-autoconf at gnu.org. ##
configure: WARNING:     ## ------------------------------------ ##


2) Seemingly missing OSD.h include in playlist.m

error:
g++ -DHAVE_CONFIG_H -I. -I. -I../../..   -DSYS_DARWIN -I../../../include
`top_builddir="../../.." ../../../vlc-config --objcflags builtin macosx`
-Wsign-compare -Wall  -no-cpp-precomp -D_INTL_REDIRECT_MACROS -pipe -c 
-o
libmacosx_a-playlist.o `test -f 'playlist.m' || echo './'`playlist.m
playlist.m:56:17: OSD.h: No such file or directory

diff:
55a56
 > #include <OSD.h>

3) Multiple wxEntry definitions.

error:
g++ -DHAVE_CONFIG_H -I. -I. -I../../..   -DSYS_DARWIN -I../../../include
`top_builddir="../../.." ../../../vlc-config --cxxflags plugin 
wxwindows`
-Wsign-compare -Wsign-compare -Wall  -no-cpp-precomp
-D_INTL_REDIRECT_MACROS -pipe -c -o libwxwindows_plugin_a-wxwindows.o
`test -f 'wxwindows.cpp' || echo './'`wxwindows.cpp
wxwindows.cpp: In function `void Init(intf_thread_t*)':
wxwindows.cpp:256: error: call of overloaded `wxEntry(int&, char*[1])' 
is
    ambiguous

wxEntry(int&,
    wxChar**)

./modules/gui/wxwindows/wxwindows.cpp-stock
254a255,256
 > #else
 >     wxEntry( i_args, p_args );

4) Broken references to vout_OSDMessage.  I simply commented out all 
the references to the funtion to get around this.  (Obviously not a 
good fix.)

error:
gcc -Wsign-compare -Wall -no-cpp-precomp -D_INTL_REDIRECT_MACROS -pipe 
-o

ld: Undefined symbols:
_vout_OSDMessage

temp fix:
commented out references to vout_OSDMessage in lirc.c, hotkeys.c,
controls.m, and playlist.m

5) Case-sensitive directory reference.  This may not be a problem when 
building under HFS(?), I'm building on UFS, so I needed to make the 
capitalization fix to continue.

error:
** BUILD SUCCEEDED **
cp -r ./tmp/extras/MacOSX/build/vlc.bundle \
       ./VLC.app
cp: ./tmp/extras/MacOSX/build/vlc.bundle: No such file or directory

Need to fix capitalization for case sensitive filesystems:

diff:
Makefile.am

3698c3698
< @HAVE_DARWIN_TRUE@    cp -r
$(top_builddir)/tmp/extras/MacOSX/build/VLC.bundle \
---
 > @HAVE_DARWIN_TRUE@    cp -r
$(top_builddir)/tmp/extras/MacOSX/build/vlc.bundle \

Other notes: Currently the playlist window does not function.  I'm not 
sure why not. :'(  The button toggles, but no playlist appears.


Thanks for the great work!  I hope this feedback helps.


Phil
