Incompatible library version after running L2A_Process --help

Optical Toolbox sen2cor
#1

hi trying to execute L2A_Process --help this is the output :slight_smile:

ImportError: dlopen(//anaconda/lib/python2.7/site-packages/osgeo/_gdal.so, 2): Library not loaded: @rpath/./liblzma.5.dylib
Referenced from: /anaconda/lib/libgdal.20.dylib
Reason: Incompatible library version: libgdal.20.dylib requires version 8.0.0 or later, but liblzma.5.dylib provides version 6.0.0

I already tried to update gdal but is up to date
I did search for the liblzma.5.dylib or the libgdal.20.dylib libraries but nothing happened.

Im on mac trying to run from command line

thanks in advance for your help

#2

It’s a (new occurring) dependency problem from libgdal wich is described here:

The solution which is described there worked for me as well:
execute: conda update xz from the command line.
Seems like libgdal should have a version dependency on xz.

after following this procedure L2A_Process runs again:

Referenced from: /Users/XXX/anaconda/lib/libgdal.20.dylib
Reason: Incompatible library version: libgdal.20.dylib requires version 8.0.0 or later, but liblzma.5.dylib provides version 6.0.0

why sen2cor could not work? I have to integrate sen2cor with SNAP when I open SNAP every time.
