I don't want to get into too much background here as the project I'm
working on has lots of mundane details and crazy history.
The short version:
Application is a GTK app using DirectFB.
I've got two systems:
System 1 (no build details known)
- Application displays fine.
- #ldd <app> (these are the libraries in addition to the libraries
found on System 2)
+ libpng12
+ libselinux
- #ldd -u <app> lists libpng12 as unused.
System 2 (all build details known)
- Application does not display properly
- Some GtkImages/GtkFixed/GtkEventBox/GdkDrawingArea don't
display.
- Despite not displaying properly, the events on the
GtkEventBox(s) are still received and handled.
- Posting the source is not an option as it's way too complex
and obfuscated.
- #ldd <app> (these are the libraries in addition to the libraries
found on System 1)
+ libcairo
+ libiconv
+ libpangocairo
+ libpixman
Notes:
- Selinux is disabled on System 2 and the libraries are compiled that
way (System 1::+ libselinux shouldn't matter)
- PNGs are not used in the app, so I left that library out of System 2
as well (System 1::+ libpng12 shouldn't matter)
- libiconv is used as glibc and its charset conversion isn't part of
System 2 - this works fine (System 2::+ libiconv doesn't matter).
Questions:
- Why doesn't System 2 display properly when the same source code is
used on System 1?
- In compiling GTK libraries, cairo(+pixman) were listed as required.
Is this not right?
ANY help/suggestions would be appreciated before I begin rewriting the
application in a less obscure (and working) way.
Thanks in advance,
- Gareth
