Building VLC1.1.0 for IOS with Xcode4.5 Mountain Lion
Posted: 29 Jan 2013 20:13
VLC1.1.0 for IOS is a little out of date. Since Xcode and some sources have been changed. Compiling VLC1.1.0 for IOS is not easy. I made it once about one year ago. I don't remember how I made it any more. Yesterday I started working on it, and finally I made it again today. Since most information about building VLC for IOS on the Internet is slightly out of date and hard to follow. I want to share my experience here.
I didn't get a macbook, I'm just happen to get a VMware Virtual Machine installed Mountain Lion and Xcode4.5. So I use it. But I suggest using Mac computer.
Here's my environment:
I assume you already get a mac and installed with Xcode4.5. Here we go!
1.Check whether GCC is installed or not.
after Xcode 4.2 in Lion, gcc is an optional component for Xcode. So we must check it.
Open a terminal , type
if it shows this
then your need to install gcc first. if it shows something like "...gcc version 4.2.1..." then go to step 2.
Here's how to install gcc: Xcode-->Preferences-->Downloads-->Components. then Click install Command Line Tools
2.Download three source tars form http://www.videolan.org/vlc/download-ios.html, unpack them.
3.rename the folder you just unpacked.
VLC-iOS-1.1.0-sources ----> vlc
MediaLibraryKit-1.1.0-sources ----> MediaLibraryKit
MobileVLC-1.1.0-sources ----> MobileVLC
4.Put them under one folder then move MobileVLC\buildMobileVLC.sh to that folder.
So here's that folder looks like
┎----vlc
┃
┣----MediaLibraryKit
┃
┣----MobileVLC
┃
┗----buildMobileVLC.sh
5. open /vlc/extras/contrib/bootstrap with text editor.
find this part and add EXTRA_LDFLAGS="${EXTRA_LDFLAGS} -isysroot ${IOS_SDK_ROOT}"
6.vlc/extras/contrib/src/Makefile
add --disable-asm\
or you'll see this
7. vlc\extras\package\ios\build_for_iOS.sh
find them and change
8. /vlc/extras/contrib/src/Makefile
find this
remove ; sh ./bootstrap
or you may see this error
9. /vlc/extras/contrib/Makefile
find this
remove /testing
10. /vlc/extras/contrib/bootstrap
change
to
or you'll meet this error:
11. finally you can run buildMobileVLC.sh if you are lucky,run this script twice,if no error appear, open MobileVLC/MobileVLC.xcodeproj, that's it .
notice: live555 may hit error when you first run the script. try it again, then it wouldn't show up. but some other error information may appear.
if you run buildMobileVLC.sh it may give you 3 or 4 error information, it's so confusing. , it wouldn't stop when it hits error.so I suggest at the beginning, you run build_for_iOS.sh can help you find more details.

You need to add extra symbolic links to /Developer to achieve correctly
