5 years ago hi,
I just happened to read your entry. I have to add that I am neither a developer nor a user of p4vasp; I only installed it for others ;-) As a first step you should find the file _cp4vasp.so on your system ($HOME maybe). And then find out via ldd which libraries _cp4vasp.so was linked against. on me, on a linuxmint19 system it looks like this: user@host:~$ ldd /usr/lib/python2.7/dist-packages/_cp4vasp.so linux-vdso.so.1 (0x00007ffe51b8f000) libGLU.so.1 => /usr/lib/x86_64-linux-gnu/libGLU.so.1 (0x00007f4bcc5e1000) libGL.so.1 => /usr/lib/x86_64-linux-gnu/libGL.so.1 (0x00007f4bcc355000) libXext.so.6 => /usr/lib/x86_64-linux-gnu/libXext.so.6 (0x00007f4bcc143000) libXft.so.2 => /usr/lib/x86_64-linux-gnu/libXft.so.2 (0x00007f4bcbf2e000) libfontconfig.so.1 => /usr/lib/x86_64-linux-gnu/libfontconfig.so.1 (0x00007f4bcbce9000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f4bcbaca000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f4bcb8c6000) libX11.so.6 => /usr/lib/x86_64-linux-gnu/libX11.so.6 (0x00007f4bcb58e000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f4bcb205000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f4bcae67000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f4bcac4f000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4bca85e000) libGLX.so.0 => /usr/lib/x86_64-linux-gnu/libGLX.so.0 (0x00007f4bca62d000) libGLdispatch.so.0 => /usr/lib/x86_64-linux-gnu/libGLdispatch.so.0 (0x00007f4bca377000) libfreetype.so.6 => /usr/lib/x86_64-linux-gnu/libfreetype.so.6 (0x00007f4bca0c3000) libXrender.so.1 => /usr/lib/x86_64-linux-gnu/libXrender.so.1 (0x00007f4bc9eb9000) libexpat.so.1 => /lib/x86_64-linux-gnu/libexpat.so.1 (0x00007f4bc9c87000) /lib64/ld-linux-x86-64.so.2 (0x00007f4bccc60000) libxcb.so.1 => /usr/lib/x86_64-linux-gnu/libxcb.so.1 (0x00007f4bc9a5f000) libpng16.so.16 => /usr/lib/x86_64-linux-gnu/libpng16.so.16 (0x00007f4bc982d000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f4bc9610000) libXau.so.6 => /usr/lib/x86_64-linux-gnu/libXau.so.6 (0x00007f4bc940c000) libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007f4bc9206000) libbsd.so.0 => /lib/x86_64-linux-gnu/libbsd.so.0 (0x00007f4bc8ff1000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f4bc8de9000)
Check' if libexpat has been installed on your system-package and libexpat-dev-package; myabe you need to set an LD_LIBRARY_PATH? or, if you have already a higher version than libexpat.so.0 installed, maybe it is sufficient just to link symbolically, let's say libexpat.so.1 to libexpat.so.0 (I know it's dirty but wirth giving it a try) well, just tried to help a bit with some suggestions...
or maybe after having installed the package libexpat-dev you need to compile the whole p4vasp once agin? well, hope I could help at least a little bit!! best Michael

Hello, I installed p4vasp on a unix system and it seemed to be fine. But when I started p4vasp by typing p4v, several errors showed. Could you please let me know what should I do in this case? Best wishes and regards!
