Hello,

It produce this error:

Code: Select all

error: can't exec 'xcrun clang' (No such file or directory)
I have try command below but there is no change:

Code: Select all

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/
Steps to reproduce the error:

Code: Select all

git clone http://code.videolan.org/videolan/VLCKit.git cd VLCKit ./buildMobileVLCKit.sh -f
This is a more complete log of the error:

Any help is very welcome.
I'm on latest MacOs Sierra with latest Xcode.

The command alone works fine:

Code: Select all

Someone know where in the build process the SharedPrecompiledHeaders folder is build with MobileVLCKit_Prefix.pch.data file that contain this line:

The start has a backslash that i want to remove:

Code: Select all

CommandLine xcrun\ clang
But after hours of search i can't find how to remove it at build time.
If i remove it in file created, when i compile again the file is generated again with this backslash.

Well, if i compile the project myself with command line, i now have this line that works:

Code: Select all

CommandLine /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -x objective-c-header...
Don't know how to solve the problem but for people who want to compile it by hand and as a note for myself in the future, this how to do.

Clone the branch you need.

If you don't have it, install xz with brew(google for brew if need to install it):

Code: Select all

brew xz
Go into cloned repo and start a first build try:

Code: Select all

./buildMobileVLCKit.sh -f
The compilation probably fail because of some archive missing, download them and put them in vlc/contrib/tarballs.
Another archive is need but i don't know where to copy it then just edit the file in vlc/extras/tools/packages.mak and replace the ANT line with this:

Code: Select all

ANT_VERSION=1.9.7 ANT_URL=$(VIDEOLAN)/apache-ant-$(ANT_VERSION)-bin.tar.bz2
Compile again but with -n option added:

Code: Select all

./buildMobileVLCKit.sh -fn
Compilation may fail when build Framework, just do it by hand.

For Iphone:

Code: Select all

xcodebuild -project "MobileVLCKit.xcodeproj" -target "MobileVLCKit" -sdk iphoneos -configuration Release ARCHS="armv7 armv7s arm64" IPHONEOS_DEPLOYMENT_TARGET=8.0
For simulator:

Code: Select all

xcodebuild -project "MobileVLCKit.xcodeproj" -target "MobileVLCKit" -sdk iphonesimulator -configuration Release ARCHS="i386 x86_64" IPHONEOS_DEPLOYMENT_TARGET=8.0
And to build framework:

Code: Select all

cd build mkdir MobileVLCKit.framework lipo -create Release-iphoneos/libMobileVLCKit.a Release-iphonesimulator/libMobileVLCKit.a -o MobileVLCKit.framework/MobileVLCKit chmod a+x MobileVLCKit.framework/MobileVLCKit cp -pr Release-iphoneos/MobileVLCKit MobileVLCKit.framework/Headers
