Hi there,

I have just installed GIP on my macbook (OS: El Capitan) using ./GPI_Install_Latest-rc.sh ~/gpi_stack.

When I attempt to open GIP I get the following console output:

Reason: Incompatible library version: libQtGui.4.dylib requires version 39.0.0 or later, but libpng16.16.dylib provides version 34.0.0

I did a re-installation of pnglib, which did not change anything. Should I also re-install GIP, and if so, how do I do that? Any other suggestions to overcome this error?

Best regards,
Esben

Hi Esben,

I see the same issue. It looks like the latest pyqt package might not be compiled with the correct version of libpng (similar to this past Anaconda problem https://groups.google.com/a/continuum.io/forum/#!topic/conda/vTn7xNkCkhM) it looks like reverting back to the last pyqt and qt builds works for me. Try this:

/Users/esbenplenge/gpi_stack/bin/conda install pyqt=4.11.4=py35_1 qt=4.8.7=1

@aganders3 This doesn't seem to affect the Linux install.

I updated the GPI_Install_Latest.sh script so that it won't install the conflicting qt and libpng packages. Its posted on https://github.com/gpilab/framework/releases

@nckz Thanks!

/Users/esbenplenge/gpi_stack/bin/conda install pyqt=4.11.4=py35_1 qt=4.8.7=1

did the trick.

Ok it seems that the following Anaconda packages are in conflict:

  • pyqt 4.11.4 py35_3
  • qt 4.8.7 3
  • libpng 1.6.17 0

GPI v1.0.2 will require the 2nd build number for these packages so it is advisable not to upgrade these to the 3rd build.

I'm going to close this since we have a work around.
