Mono 3.4.0 mkbundle under Mac OS X failed

Question

I`m trying to make static binary under MAC OS X 10.9 (Mavericks) which is not require mono runtime. This is almost clean machine with the latest updates and the latest XCode.

If I do not set the build architecture, I have the following:

mkbundle client-patcher.exe -o client-patcher
OS is: Darwin
Sources: 1 Auto-dependencies: False
   embedding: /Users/radubalan/tmp/client-patcher.exe
Compiling:
as -o temp.o temp.s
cc -g -o client-patcher -Wall temp.c `pkg-config --cflags --libs mono-2`  temp.o
ld: warning: ignoring file /Library/Frameworks/Mono.framework/Versions/3.4.0/lib/libmono-2.0.dylib, file was built for i386 which is not the architecture being linked (x86_64): /Library/Frameworks/Mono.framework/Versions/3.4.0/lib/libmono-2.0.dylib

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
ERROR: [Fail]

If I do set architecture by

export AS="as -arch i386"
export CC="cc -arch i386"

I`m getting the following:

mkbundle --deps --static -z client-patcher.exe -o client-patcher
OS is: Darwin
Note that statically linking the LGPL Mono runtime has more licensing restrictions than dynamically linking.

Is the possibility to make MRE-independent bundle completely broken under Mac OS X?

The same bundle under Linux (Debian) is produced without any problems.

Thank you in advance!

Answer 1

To clarify, you need to add the following to that last cc command:

-framework CoreFoundation -lobjc -liconv 

So in your case the command:

cc -arch i386 -o client-patcher -Wall pkg-config --cflags mono-2 temp.c -lz pkg-config --libs-only-L mono-2 pkg-config --variable=libdir mono-2/libmono-2.0.a pkg-config --libs-only-l mono-2 | sed -e "s/\-lmono-2.0 //" temp.o

Should be re-written with those flags in front of cc:

cc -framework CoreFoundation -lobjc -liconv -arch i386 -o client-patcher -Wall pkg-config --cflags mono-2 temp.c -lz pkg-config --libs-only-L mono-2 pkg-config --variable=libdir mono-2/libmono-2.0.a pkg-config --libs-only-l mono-2 | sed -e "s/-lmono-2.0 //" temp.o

Simply cut/paste that last cc command, add those flags to it, cut/paste back into the terminal, hit enter and enjoy.

Answer 2

You need to link the binary with the CoreFoundation framework. This is a recent change in Mono 3.4 as per the Mono 3.4 release notes. A similar issue was reported a while ago.
