    initial v1  
    1 at present, on systems that support @rpath, meson uses @rpath during the build and test phase.

    33From the top of the build directory, the @rpath library references are constructed and embedded into the executables. The libraries are all named with the @rpath/dylibname.dylib syntax, no matter where they are in the build tree, usually.
    … …  
    55Then later, at the install phase, all the @rpath references are stripped out, the libraries are installed with their final full static names, and any installed executables are rejigged to point to those final installed library names.

    7 meson assumes darwin is a standard @rpath using system, which it is, on 10.5+, and so meson is written assuming darwin is using @rpath.

    9 I hacked meson to use @loaderpath instead of @rpah for the library names, and this works surprisingly well, except with the libraries in the build directory are not in the same folder as the executables in the build directory, in which case it fails as it doesn't know what subdirectory to look in.

    11 Instead of @loaderpath, if I could make meson use the full library path name, even in the build directory, then it would all work. Some other systems, like Windows, do this with meson. But there are intricacies to it and you can't just Bogart meson to use the full library path name on darwin like it does on windows, as there are many places in meson that windows or darwin code paths diverge.

    13 I often can fix these manually -- changing the library path names in the build directory, or symlinking or moving a library into a workable spot -- but I'm not about to write a bunch of spaghetti like that for meson ports in general, so I have not been uploading that crud to MacPorts.

    15 It can be done -- making darwin not use @rpath, but use full path names like windows does -- but meson is a moving target, and it would be a project to do it -- and unless upstream is interested in taking this on, it's kindof a lost cause. And upstream has almost NO darwin users, and certainly NONE that use legacy systems. So that is a long long long shot.

    1717We could fork meson and make it not use @rpath -- I am not interested in that project. Life is too short for me to do that.

    1919SO -- we hack a bit, hope for the best, peg the really tricky ones like at-sp2-atk.

    21 I am wondering if a wrapper script for ld might be written that could make @rpath references work. OR if the dyld from Leopard could be built and installed on Tiger as that one supports @rpath.

    23 BUT unless we sort this out soon, Tiger is doomed as meson, with all it's warts, seems to be taking up a prime place in the GNOME world.
