Cannot mix incompatible Qt library with this library #2894

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
In Fritzing versions 0.8.6b and 0.8.7b, the `Fritzing` executable script in the 
root directory of the Linux download does not work for me. I get:

  $ cd fritzing-0.8.7b.linux.AMD64
  $ ./Fritzing
  Cannot mix incompatible Qt library (version 0x40803) with this library (version 0x40805)
  Aborted

I've found a simple workaround, which is simply to comment out this line of the 
`Fritzing` script:

  export LD_LIBRARY_PATH

but I haven't dug into it further to figure out why it happens. I'm on 
LinuxMint 14 (Ubuntu-based) with a stock 3.5.0 kernel; there's various Qt stuff 
installed on my system, looks like 4:4.8.3. Please let me know if any other 
info is needed.

Thanks for the helpful info and the workaround. If you open up the Fritzing 
about box (under the Help Menu), the version number of the Qt Fritzing is using 
should be at the top. I wonder whether you will see 4.8.5 (which is the library 
we ship with Fritzing) or 4.8.3 which you report is the version number for the 
Qt installed on your system.

The Fritzing "About" dialog indicates Qt 4.8.5.

Interesting. I am no Linux expert, but it sounds like we should do some 
tinkering with the launch script. The idea for it at least, was to run Fritzing 
using the Qt libraries that we ship with it, as opposed to whatever Qt 
libraries might already be installed on the machine. The launch script is meant 
to be only relevant for our Ubuntu builds; if you are using a third party 
build, that script is likely not correct.
