When I install Qt 4 without the deprecated Qt3Support module, AMOS fails to configure correctly:
```
checking for Qt4... yes
checking whether Qt4 works... no
```
And in config.log
```
configure:7163: ++ -lz -lc -lm -o amos_qt amos_qt.o moc_amos_qt.o -F/usr/local/Cellar/qt/4.8.4/lib -L/usr/local/Cellar/qt/4.8.4/lib -framework Qt3Support -framework QtGui -L/usr/local/Cellar/qt/4.8.4/lib -F/usr/local/Cellar/qt/4.8.4/lib -framework QtCore
ld: framework not found Qt3Support
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
Is Qt 3 actually needed by AMOS?
Cheers,
Shaun
Hey Shaun,
Hawkeye is the only amos tool that uses Qt. It was originally written in Qt3. Mike updated the code to Qt4 using the Qt3 compatibility classes, so yes, I think Qt3Support is required ... Mike could confirm ... If you don't need Hawkeye, then you can just ignore the build error.
Best,

Okay. Thanks for clarifying, Adam.
