Hi all,

I have tried to install LyX 2.0.0&  2.0.1 several times on my Ubuntu-run laptop 
... without success. After apparently successfully compiling, LyX spits out the 
following error when launched:

lyx: symbol lookup error: lyx: undefined symbol: _ZN9QListData11detach_growEPii

A quick browse on the internet established a link between this error and the Qt 
4 Frontend libraries as similar errors have been reported for other programs. I 
have nonetheless not been able to find a solution when it comes to dealing with 
LyX.

Any help will be welcome. I attach:
  - config.log: the log file of the ./configure command;
  - configure.log: the output to stdout of the ./configure command;
  - make.log: the output to stdout of the make all command.

None of those came through.

What version of Qt are you trying to use here?

Richard

PS I'm cross-posting to lyx-devel, which is probably a better bet.

It looks like you're trying to run lyx with a different version of Qt than the one which you used during building.
