libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

[probonopd]

Debian 11 Bullseye (Build 4) has the following issue:

./AppRun: symbol lookup error: /usr/lib/x86_64-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

Debian 11 Bullseye (Build 3) did not have the issue.

How can it be that such things break from one build to the next?

I am so sick and tired of this kind of BS.

• linuxdeployqt blacklists libfontconfig probonopd/linuxdeployqt#261
• libfontconfig  probonopd/linuxdeployqt#259

Just confirming that the proposed fix of excluding libharfbuzz.so.0 and libfreetype.so.6 from the AppImage works for me as well to get my own AppImage of Peek run again on Arch.

TODO: Check workaround:

LD_PRELOAD=/usr/lib/libfreetype.so ./AppRun

./xxx: symbol lookup error: /lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

same issue,
work for me:

if [ -L /usr/lib64/libfreetype.so ];then
    export 'LD_PRELOAD=/usr/lib64/libfreetype.so' 
fi
exec my_c++_bin

Then make an AppImage that includes dependencies needed for the app to work ;) You can't just link against some random libfontconfig where the app was built and think it will work on other systems. You need to package the application properly.

The exclude list (probonopd/linuxdeployqt#261) is doing more harm than good.
