I don't have a GCW0 yet (waiting for one in March when the kickstarter succeeds) but today I installed the linux devkit in a VirtualBox Ubuntu installation and managed to compile GpMark (the latest source on Opendingux for Dingoo, hope the keymappings are similar, even though it's not important for benchmarking). I would be happy if someone would try to run this on his GCW0 and report the results. Just curious how good it performs compared to Caanoo or other handhelds.
ftp://ftp.untergrund.net/users/optimus/progs/gcw0/preview/gpmark_gcw0_test.zip (if fail, try twice, sometimes untergrund fails and seems like file does not exist, but needs click twice or right click, save as)
Inside I have the OPK with essential binary file (the big 2MB 3d bunny mesh and the draculin texture for rotozoomer) and the source code too.
If it fails at first time I won't beg you to try other tests (it's tedious by distance, I prefer to wait for the handheld) and if someone wants he can try to compile the source and make it work properly. But if it runs at first time (hopefully there isn't any bug that makes it underperform), it would be awesome to read results.
