[GRASS-dev] Seeking advices for image segmentation algorithms and windows compile question

Sun May 8 21:12:12 PDT 2016

Hi All,

Thanks Moritz! Actually, this weekend I've tried both. I assume win10 is too new so I tried win 7 and win8.1 using different computers. I followed same tutorial [0], after I compiled for release builds on 64bit, I got the error report for both win 7 and win 8.1 OS:
>Errors in:
>/usr/src/grass_trunk/raster/r.in.lidar
>/usr/src/grass_trunk/raster3d/r3.in.lidar
>/usr/src/grass_trunk/vector/v.out.lidar
>/usr/src/grass_trunk/vector/v.in.lidar

I tried to change into the directory with error and run 'make'. The error msg was long and I think I need time to read them.

I've also tried compile GRASS on VM OS X El Captain using homebrew[1] first. But got stuck at:

brew install --HEAD grass-71
==>Installing grass-71 from rkrug/head-only
==>Cloning https://svn.osgeo.org/grass/grass/trunk
then the terminal freezing here forever. 

Sorry for the slow progress. I think I need more time to do the research work. Any help would be appreciated.

Best,
Bo Yang

Hi all,

[Bo, please keep such discussions on the list.]

Even though I agree with Maris that compiling in GNU/Linux is easier, I do think that we should rather support those who want to develop in a windows environment. We lack windows devs, and telling everyone at the first difficulty to move over to GNU/Linux will not increase that number.

Helmut, would you have any advice to give to Bo on his issue in launching the windows version ?

Moritz
