nextpnr-ice40 --gui not working #271

Open jmhmot opened 5 years ago

jmhmot commented 5 years ago

I have compiled nexpnr and all seems to be working fine in non-gui mode, but when I run: nextpnr-ice40 --gui at the terminal nothing happens, no CPU activity, no output, terminal held waiting.... I'm using Ubuntu 16.04. gdb attach to process states: ...Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". pthread_cond_timedwait@@GLIBC_2.3.2 () at ../sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:225 225 ../sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S: No such file or directory. Sorry I'm not really experienced to know if this is a clue to the problem or not. Is the gui having some thread-locking issues?

I built nextpnr from the instructions given at: http://www.clifford.at/icestorm/

Please, does anyone have any suggestions?

@jmhmot, I just ran nextpnr-ice40 --gui at my terminal on an Ubuntu 16.04 platform with no problems. Could this problem be due to a missing dependency? Dan

@ZipCPU Thanks for your reply. How would I go about finding which missing dependency? Could it be a graphics driver issue? I'm using 2 graphics card (for 4 monitors). Output from lshw -c video is: -display

Can you run glxinfo | grep "OpenGL version and let us know what version of OpenGL you are using?

jmhmot commented 5 years ago

Hi ZipCPI $glxinfo | grep "OpenGL version" gives: $OpenGL version string: 3.0 Mesa 18.0.5

mmicko commented 5 years ago

Ok, so probably issue is hardware/OpenGL supported version. Minimal version nexpnr is supporting and enforcing is 3.2, we are letting users run anyway since 3.1 could even work on some, but it is unsupported. So bad news is that you hardware just can not be supported due to opengl calls use by shaders inside nextpnr :(

ric96 commented 5 years ago

same as #240 ?

ric96 commented 5 years ago

@jmhmot can you check now with --gui-no-aa ? Its solved for me

jmhmot commented 5 years ago

@ric96 I just cloned the latest code and rebuilt it. Then ran : $nextpnr-ice40 --gui --gui-no-aa and.... no change, command line hangs doing nothing as before. BTW I do have it all working on another PC also with Ubuntu 16.04 (but different hardware, an X220 laptop). Anyone any idea why it would hang doing nothing?

This happened to me a while ago. The problem was that I had upgraded some of the underlying OS packages. The fix, I believe, was to rebuild nextpnr.
