macports / brew / pkgsrc ??? about osxcross

[tpoechtrager]

MacPorts might be worth a try:

Running on platforms other than Mac OS X is not the main focus of The MacPorts Project,
so remaining cross-platform is not an actively-pursued development goal. Nevertheless,
it is not an actively-discouraged goal either and as a result some experimental support
does exist for other POSIX-compliant platforms such as *BSD and GNU/Linux.

I was able to install macports on linux. IIRC the problem would be the need to touch all the port files to use a cross compiler.

[tpoechtrager]

Modifying MacPorts would probably also work, especially libexec/macports/lib/port1.0/portconfigure.tcl.

[maci0]

ok, will look into that then. if i get it working somehow i will write something up

[maci0]

@tpoechtrager i came up with this: https://github.com/maci0/pmmacports
its not perfect but works for my use case and i was able to compile a rather complex project using osxcross

[tpoechtrager]

Good job. I will integrate it into OSXCross soon.
Are you fine with GPL2 and an entry in AUTHORS?

[maci0]

@tpoechtrager take it :) I'm fine with GPL2 as well, just picked BSD for its simplicity.
Might be wise to add a check at the beginning of the script to see if lynx and wget are installed.

also instead of main $PACKAGES one could change it to main $* to accept the packagelist from commandline

[tpoechtrager]

I already got rid of lynx and improved/fixed a lot of other things:

i guess you will run into problems with pkg-config if you dont install this under /opt/local .. perhap sits enough to change the .pc files but im not sure

[tpoechtrager]

I am planning to make MacPorts installed libraries directly usable with OSXCross
(or at least optionally), so there is no need for -isystem /-I / -L/ pkg-config etc.

But seding the *.pc files may not be wrong either.

[tpoechtrager]

Ok, I will go the opt/ + PKG_CONFIG_SYSROOT_DIR + PKG_CONFIG_PATH way, other directories are causing lots of troubles...

i.e.:

export OSXCROSS_PKG_CONFIG_SYSROOT_DIR=/home/thomas/development/osxcross/target/macports
export OSXCROSS_PKG_CONFIG_PATH=/home/thomas/development/osxcross/target/macports/opt/local/lib/pkgconfig

$ x86_64-apple-darwin13-pkg-config --libs SDL2_mixer
-L/home/thomas/development/osxcross/target/macports/opt/local/lib -lSDL2_mixer -lSDL2 
$ x86_64-apple-darwin13-pkg-config --cflags SDL2_mixer
-D_THREAD_SAFE -I/home/thomas/development/osxcross/target/macports/opt/local/include/SDL2 -I/home/thomas/development/osxcross/target/macports/usr/include/SDL2 

Thanks for the hint!

[maci0]

all i did to get my project compiling was
export OSXCROSS_PKG_CONFIG_LIBDIR=/opt/local/lib/pkgconfig might be the wrong way tho. there is lots of conflicting pkgconfig information floating around the net

[tpoechtrager]

Added a minimalistic macports packet manager in 5a21748.
Sorry for the long delay.
