I'm working on a new build of PyQt-Mac. Everything seemed to build fine (Qt 3.3.4, latest versions of QScintilla, SIP, and PyQt), and install without incident. However, PyQt applications no longer launch: it seems they don't see libqscintilla. Here's a typical message:
Contents/MacOS/Eric 3 can't open library: libqscintilla.5.dylib (No such file or directory, errno = 2)
This is puzzling because that library is correctly installed in
/Developer/qt/lib, which is where it should be. So I don't see why these
other apps can't see it.
Looking at the logs from building PyQt, I ran across this strange warning:
ld: warning -L: directory name (/Users/kevin/Desktop/qt-mac-free-3.3.4-shared/lib) does not exist
The directory that "does not exist" is the build directory for Qt. After
~ building Qt, I moved the build folder to /Developer and renamed it qt.
Then I began building PyQt and the other bits.
I'm pretty sure that these other apps think that libqscintilla.dylib
should be in /Users/kevin/Desktop/qt-mac-free-3.3.4-shared/lib. But why?
~ What difference does it make, especially when I have $QTDIR set in my
path to point to /Developer/qt? And if this is a problem, how do I fix
it (short of rebuilding Qt in /Developer/qt--groan...)
The problem here is that the Qt developers did a poor job of porting to the Mac and don't set the proper install_name on these libraries. You will need to run install_name_tool over them after putting them in the bundle. Better yet, run macho_standalone from py2app svn on the app.
