Binary bundling under macosx?

Postby gradha » Mon Jan 17, 2011 3:05 pm

I'm trying to embed a cobra binary with mono so it is standalone and can be run from the command line. For this purpose I compile the cobra source into an exe. Then, I try to follow the instructions at http://www.mono-project.com/Guide:Runni ... plications, mainly:
Code: Select all
mkbundle -o build/bbiribbabba src/bbiribbabba.exe --deps

However, at some point it all fails with some junk character errors:
Code: Select all

I've tried this with a recent cobra and 2.8.2 mono, along with the CSDK, though I'm not sure if that's even needed. Has somebody else tried building a standalone cobra binary with success under macosx?

Ack, just figured out I would test at least a normal binary and it doesn't work either. I'll look somewhere else, sorry. I found http://go-mono.com/forums/#nabble-td1549390 but I'm lost as to how I'm supposed to figure out the pkg-config local problem, I only have the pkg-config from macports.

Let us know how it goes. I tried mkbundle on Mac with Mono 2.6.7 and got the same errors. I tried on another Mac with Mono 2.8.1 and then 2.8.2 and also got errors. I tried different combinations of flags which only changed which errors occurred.

I don't need mkbundle at this time, but it would be interesting to know what it takes to get it working on Mac.

I managed to get it going after tinkering with the answers found at http://go-mono.com/forums/#nabble-td2717076. My current binary build script is:
Code: Select all
#!/bin/sh

export AS="as -arch i386"
export CC="cc -arch i386"
export PATH=/Library/Frameworks/Mono.framework/Commands/:$PATH

rm -Rf build &&
mkdir -p build &&
mkbundle src/bbiribbabba.exe --deps -c -o temp_prog.c --keeptemp &&
$CC -O -o build/bbiribbabba -Wall temp_prog.c \
   `pkg-config --cflags --libs mono-2` temp.o \
   -framework CoreFoundation


Since mkbundle is not being used, I don't know what magic it uses for parameters like --static or -z, both of which don't work. The former presumably because I'm linking manually with gcc, the latter because the as command seems to fail with linking issues due to missing decompression code.

At least I get a dynamically linked 6MB cobra hello world binary. Not that bad. Maybe I'll try later the mono-osx mailing list for support.

Finally got it working. The details are at http://lists.ximian.com/pipermail/mono- ... 03716.html. I ended up using upx (http://upx.sourceforge.net/) in the end since it achieves a higher compression ratio: 3.5MB cobra hello world statically linked binary, which works at the other side of a dropbox. My updated script:
Code: Select all
#!/bin/sh

export AS="as -arch i386"
export CC="cc -arch i386"
export PATH=/Library/Frameworks/Mono.framework/Commands/:$PATH

rm -Rf build temp.* temp_prog.? &&
mkdir -p build &&
mkbundle src/bbiribbabba.exe -z --deps --static -o build/bbiribbabba
