Hi all, The adventure continues ... Now analysis won't open at all. I get the following error message when I try to open. Error, the Analysis module will not work, something is wrong with the C code. Traceback (most recent call last): File "/home/douglas/Documents/Programs/software/analysis/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/AnalysisGui.py", line 70, in ? from ccpnmr.analysis.AnalysisPopup import AnalysisPopup File "/home/douglas/Documents/Programs/software/analysis/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/AnalysisPopup.py", line 90, in ? from ccpnmr.analysis.Analysis import Analysis File "/home/douglas/Documents/Programs/software/analysis/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/Analysis.py", line 83, in ? from ccpnmr.c.ContourFile import ContourFile ImportError: Failure linking new module: /home/douglas/Documents/Programs/software/analysis/ccpnmr/ccpnmr1.0/python/ccpnmr/c/ContourFile.so: Symbol not found: __cg_png_create_info_struct Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO Expected in: /sw/lib/libPng.dylib I tried to recompile the C code. It went off without a hitch but analysis still spits out an error message. Justin
