Hi, I have trouble running ghemical (after installing from a precompiled deb) with the following errors generated: jason at jdrig2-wired-self:~$ ghemical OpenGL extension version - 1.3 WARNING : SetCurrent() called before widget was realized ; skipping... GL is not yet initialized -> skipping light setup! added local light. WARNING : SetCurrent() called before widget was realized ; skipping... WARNING : Update() called before widget was realized ; skipping... InitGL : setting up lights for cam 0 ghemical: symbol lookup error: ghemical: undefined symbol: _Z15TransformVectorR3v3dIfEPKf This error occurs if I click the black area where you draw the molecule straight after opening the application - it crashes straight away. If I select the draw tool and attempt to place an atom, this error is generated: jason at jdrig2-wired-self:~$ ghemical OpenGL extension version - 1.3 WARNING : SetCurrent() called before widget was realized ; skipping... GL is not yet initialized -> skipping light setup! added local light. WARNING : SetCurrent() called before widget was realized ; skipping... WARNING : Update() called before widget was realized ; skipping... InitGL : setting up lights for cam 0 draw state is 1 orbit_xy skipped ; counter = 1 BUG: invalid crd_table_size_loc found. Again, the application crashes instantly. If I open and exit the application using the close option from the file menu (without doing anything more), I receive the following error: jason at jdrig2-wired-self:~$ ghemical OpenGL extension version - 1.3 WARNING : SetCurrent() called before widget was realized ; skipping... GL is not yet initialized -> skipping light setup! added local light. WARNING : SetCurrent() called before widget was realized ; skipping... WARNING : Update() called before widget was realized ; skipping... InitGL : setting up lights for cam 0 *** glibc detected *** corrupted double-linked list: 0x00000000006a62c0 *** Aborted The version of Ghemical is 1.91. If anyone could suggest a solution, it would be greatly appreciated. Also, is there a precompiled deb available for AMD64 of the new 2.01 version of ghemical? Thanks, Jason
