I am using MonoDevelop version 2.4.2 with iOS SDK 4 installed. I am encountering a problem whereby simply adding -gcc_flags to the project [build/iphone build/extra arguments] setting causes linking errors in MonoDevelop.
This is easily reproducible, just create an empty iPhone Window-based Project. Confirm that it compiles correctly. Then add a simple include path with in [build/iphone build/extra arguments] as follows:
-v -v -v -gcc_flags “-I${ProjectDir}”
With this added, when I try compile I get the following linking errors (I have removed the paths to the temporary directory to make the error messages more readable):
main.m:9:26: error: mono/jit/jit.h: No such file or directory
main.m:10:36: error: mono/metadata/assembly.h: No such file or directory
main.m:11:39: error: mono/metadata/mono-config.h: No such file or directory
main.m:12:38: error: mono/metadata/mono-debug.h: No such file or directory
main.m:13:26: error: monotouch/gc.h: No such file or directory
main.m:14:33: error: monotouch/monotouch.h: No such file or directory
It seems, therefore, with the -gcc_flags option set that MonoDevelop does not seem to find the path to the required mono and monotouch header files. Is this a known problem? Does anyone know a work around for this problem?
I am new to MonoTouch, and so maybe I am doing something wrong here… and if I am, then I would appreciate it if someone could let me know what I am doing wrong and how I can get MonoTouch to compile with -gcc_flags set.
Thanks,
Bruce
Your MonoTouch and iOS SDK versions are out of sync. Install MonoTouch 3.2.4 and iOS SDK 4.2.
