| − | MythTV currently does not build on the new Intel based Apple Macintosh platforms. This page is intended to share information among the people attempting to get this working.
| + | #REDIRECT [[Myth on Mac OS X]] |
| − | | |
| − | In the 'contrib' directory of the MythTV source code, there is a perl script which automates the build process for MythTV on MacOS systems. The script is called osx-packager.pl. My descriptions of changes needed assume that script as a starting point.

| − | ==Changes Needed==
| |
| − | Here's a brief summary of chages I made to get further into the build process (updated with Brendan White's config info):
| |
| − | | |
| − | * Override URL for libdvdnav in osx-packager.pl, was not available where the script was looking for it. I set it to: http://umn.dl.sourceforge.net/sourceforge/dvd/libdvdnav-0.1.10.tar.gz
| |
| − | | |
| − | * libdvdnav: Endian byte swapping missing from bswap.h. Probably due to not recognizing the arch. Added the generic example macro in the 'else' case & it compiled.
| |
| − | | |
| − | * libexif: compile failed. comment out the 'static' in exif-utils.c line 83.
| |
| − | | |
| − | * libdvdread: Endian byte swapping missing from bswap.h. Probably due to not recognizing the arch. Added the generic example macro in the 'else' case & it compiled.
| |
| − | | |
| − | | |
| − | MythTV changes:
| |
| − | | |
| − | * Update osx-packager.pl to add configure parameters used in building MythTV. In the section "configure mythplugins, and mythtv, etc", the 'mythtv' portion should look something like this:
| |
| − | | |
| − | 'mythtv'
| |
| − | => [
| |
| − | '--disable-distcc',
| |
| − | '--disable-mmx',
| |
| − | '--arch=i686',
| |
| − | '--extra-cxxflags=-msse -msse2 -msse3',
| |
| − | '--prefix=' . $PREFIX,
| |
| − | ],
| |
| − | | |
| − | * Fix mythtv/libs/libavcodec/liba52/resample.c -- Even though mmx has been disabled, there are some silly assumptions in this file. remove the ifdef that includes resample_mmx.c. Also remove the ifdef ARCH_X86 stanzas.
| |
| − | | |
| − | * 3rd bswap.h patch, this time in mythlibdvd
| |
| − | | |
| − | * Fix BaseClasses.h (called from Actions.cpp), #include <malloc.h> to #include <sys/malloc.h>

| − | The binary is compiling now. But, when it is executed, a bus error is generated, apparently in QT:

| − | '/proc/cpuinfo/' is used to determine CPU type in linux builds. In MacOS, "/usr/sbin/system_profiler SPHardwareDataType" could be used to determine the architecture and CPU type.
