Undefined reference to `qBadAlloc()' all over the place

jbcolmena

Hi all.

I made an application at home, compiled it, and works nicely. Now it's in a server. When I run make I get a lot of @undefined reference to `qBadAlloc()'@, from different files and fuctions... using xubuntu, just installed qt using apt-get, and well, it just doesn't compile. qmake runs fine. This is the output of make. What library am I missing? what didn't I install? have no idea...

@qmake distclean@

everything works now. Quite obvious, but well, this is my first qt app.

Cheers.

bq. qmake distclean

Just for the reference - that should be "make distclean"

You compiled your application against a Qt version that was built with exception support, but then try to partially link it again against a Qt version without exception support.

When you switch Qt versions like that, you should always run "make clean" to do a clean build.
