OSXCROSS-MACPORTS

osxcross-macports is a small "packet manager" for 16.000+ binary MacPorts packages.

Packages are installed to target/macports/pkgs.

Dependencies:

bash, wget and openssl

Also ensure that you are using the 10.6 SDK (or later).

Installation:

Run OSXCross's ./build.sh, then you should have osxcross-macports in PATH.

Setting up osxcross-macports:

MacPorts doesn't support 10.5 anymore, so we need to change OSXCross's
default target to 10.6 (better 10.7, or later).

--

It may be worth to mention that you should stay below 10.10, there aren't
a lot packages for 10.10 yet.

You can of course use (for example) 10.6 libraries on 10.10.

--

To achive this, add the following to your bashrc (or similar):

export MACOSX_DEPLOYMENT_TARGET=10.7

Then run osxcross-macports <cmd>.

Things you should know:

shortcuts:

osxcross-mp, omp

--

pkg-config:

OSXCross's pkg-config (<arch>-apple-darwinXX-pkg-config)
is automatically aware of MacPorts packages.

If you want pkg-config to be unaware of MacPorts packages
(for whatever reason), do the following:

export OSXCROSS_PKG_CONFIG_NO_MP_INC=1

--

automatic compiler includes:

You can set up automatic compiler includes (-I / -L / -F) by doing the following:

export OSXCROSS_MP_INC=1

--

verbose messages:

Can be enabled by adding '-v' or '--verbose'.

--

upgrading packages:

Run osxcross-macports upgrade.

This will simply re-install the latest version of all your installed packages.

listing all available packages:

osxcross-macports search $

Commands:

osxcross-macports [...]

  • install <pkg1> [<pkg2> [...]]

    • Install and its deps.

  • search <pkg>

    • Prints a list of matching package names.

  • update-cache

    • Updates the search index cache.

  • clear-cache

    • Clears the download and search cache.

  • remove-dylibs

    • Removes all *.dylib (useful for static linking).

  • upgrade

    • Reinstalls the latest version of every package.

Useful flags:

  • '-v', '--verbose':

    • Print verbose messages.

  • '-v=2', '--verbose=2':

    • Print more verbose messages.

  • '-s', '--static':

    • Install static libraries only.

  • '-c', '--cflags' <lib>:

    • Shows cflags for <lib> (same as pkg-config).

  • '-l', '--ldflags' <lib>:

    • Shows ldflags for <lib> (same as pkg-config).

Uninstalling is not supported (and probably never will be).

However, you can remove packages by hand. A simpler (and cleaner) way would
be to remove the whole macports directory (target/macports) and to reinstall
all other packages again.

Example:

LIB INSTALLATION EXAMPLE:

$ osxcross-macports install libsdl2
searching package libsdl2 ...
downloading libsdl2-2.0.3_0.darwin_11.x86_64.tbz2 ...
installing libsdl2 ...
installed libsdl2
