no strace on osx.
i have both gdb & ktrace -- but i haven't figured out how to capture
the trace/output of a not-yet-launched app via finder event.
but, given you're asking about file opens, i'm guessing (?) that
fs_usage /may/ provide what you're looking for ...
{
cref:
http://devworld.apple.com/documentation/Darwin/Reference/ManPages/man1/fs_usage.1.html
http://rentzsch.com/macosx/fs_usageIntro
}
on launch via cmd line, from the qt-console dir,
cd src/qt-console
./bat.app/Contents/MacOS/bat
fs_usage shows,
fs_usage -w | grep "libqwt"
11:46:01.825 open F=3
libqwt.5.0.2.dylib
0.000088 bat
which, apparently, works.
on dubl-click in Finder,
fs_usage -w | grep "qwt"
11:47:53.040 open [ 2] libqwt.5.dylib
0.000101 bat
11:47:53.040 open [ 2]
/Volumes/SystemFiles/local/lib/libqwt.5.dylib
0.000058 bat
11:47:53.040 open [ 2]
/usr/lib/libqwt.5.dylib
0.000028 bat
shows the app attempting to open the symlink:
libqwt.5.dylib
rather than
libqwt.5.0.2.dylib
where,
ls -al /usr/local/qwt-5.0.2/lib/libqwt.5.dylib
lrwxr-xr-x 1 root wheel 18 2007-08-01 22:10
/usr/local/qwt-5.0.2/lib/libqwt.5.dylib -> libqwt.5.0.2.dylib
in the cmd line example. then also,
/Volumes/SystemFiles/local/lib/libqwt.5.dylib
/usr/lib/libqwt.5.dylib
neither of which exists.
finally, again on launch via cmd line, but from a DIFFERENT dir that
the qt-console dir,
cd /tmp
/build/bacula/src/qt-console/bat.app/Contents/MacOS/bat
fs_usage shows, as before,
fs_usage -w | grep "libqwt"
11:51:01.873 open F=3
libqwt.5.0.2.dylib
0.000091 bat
so, when dubl-clicking the qt-appin finder, something's pointing to
the wrong path, or failing to point to the right one ....
