OS X prototype app rendering is broken

jakepetroules commented 12 years ago

The prototype app will not render HSS; only a blank screen is displayed. Additionally, if a simple XML file is loaded, the app will crash. Stack trace below:

This seems to have something to do with GLib but linking to it seems to have little effect. I observed this issue I think immediately after converting the app to CMake. Also note that the prototype app given to me by @veosotano linked to more libraries than our current app does, so this issue may be related to that...

Here's the otool -L output of the app given to me by @veosotano:

An overview of the differences:

The current version links to libAXR_core... this is just because I've built it as a shared library while the original's is statically linked
The current version does not link to Boost... this is just because the current version is linked statically
The original links to ApplicationServices (current doesn't) but this is probably of no consequence
cairo, pango, pangocairo, pangoft2, gobject, glib are all slightly newer versions in the current version (shouldn't be a problem)
expat is loading from different paths (but seems to be the same version)

After this, the old version links to the following libraries that the new one does not:

libffi.5.dylib (compatibility version 6.0.0, current version 6.10.0)
libgmodule-2.0.0.dylib (compatibility version 3001.0.0, current version 3001.2.0)
libgthread-2.0.0.dylib (compatibility version 3001.0.0, current version 3001.2.0)
libiconv.2.dylib (compatibility version 8.0.0, current version 8.1.0
libpixman-1.0.dylib (compatibility version 21.0.0, current version 21.2.0)
libpng15.15.dylib (compatibility version 18.0.0, current version 18.0.0)

And the new version links to the following libraries that the old one does not:

libfontconfig.1.dylib (compatibility version 7.0.0, current version 7.0.0)
libfreetype.6.dylib (compatibility version 16.0.0, current version 16.0.0)

The files I was testing with are the following:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet src="index.hss" type="application/x-hss" version="1.0"?>
<root>
    <button>Click me</button>
</root>

and

#import UIFramework;

*
{
    padding: 5;

    button
    {
        isA: UIButton;
    }

    #new box
    {
        background: @linearGradient
        {
            startColor: #f00;
            endColor: #a00;
            endY: 100%;
        };

        width: 90%;
        height: ref(width) / (16 / 9);
        alignX: center;
        alignY: middle;

        // or @roundedRect (it's the default)
        shape: @
        {
            left: 10;
            right: 20;
        };
    }
}

Loading the XML file will crash; loading the HSS file displays a blank white screen. @veosotano's app works loading either file (the button is only displayed if the XML file is loaded, which makes sense of course).

jakepetroules commented 12 years ago

Apparently something is wrong with ref() as my text file now works with the height changed to a plain integer. XML file loading is still broken.

jakepetroules commented 12 years ago

I don't know why this issue was re-opened. The XML loading was due to bad -devel packages from MacPorts and @veosotano later fixed ref(). Closing again.
