Hi Helmut,

Thanks for the prompt reply. Now I am able to compile and start GRASS, but still have a small issue. Below are my procedures:

1. I changed back to 64bit packages because I can't go through in the 32bit environmental follow the tutorial [0] (I think might because my OS is 64bit).

2. Thanks for your advice, after deleted:
there no lidar error reported (r.in.lidar, r3.in.lidar, v.out.lidar, v.in.lidar). GRASS can be built successfully.

3. As mentioned in the previous threads, the C:\OSGeo4W64\bin\grass71svn#L8 need to be changed to e.g. "SET OSGEO4W_ROOT= C:\OSGeo4W64"

4. Then run grass71svn, it reported 3 dll files are missing respectively: "libintl-8.dll/ libsystre-0/ libiconv-2 is missing from your computer";  each time it report one dll missing, I copy this file from "C:\msys64\mingw64\bin" to " C:\OSGeo4W64\bin". I don't know why still come dll missing. I installed all the components required in [0]

5. Afterward GRASS can be started in both text mode and g.gui mode.

6. I change to i.segment folder and run 'make'. It reported:
$ make
if [ "/usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin/i.segment.exe" != "" ] ; then GISRC=/usr/src/grass_trunk/dist.x86_64-w64-mingw32/demolocation/.grassrc71 GISBASE=C:/msys64/usr/src/grass_trunk/dist.x86_64-w64-mingw32 PATH="/usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin:/usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin:/usr/src/grass_trunk/dist.x86_64-w64-mingw32/scripts:$PATH" PYTHONPATH="C:/msys64/usr/src/grass_trunk/dist.x86_64-w64-mingw32/etc/python;C:/msys64/usr/src/grass_trunk/dist.x86_64-w64-mingw32/gui/wxpython;$PYTHONPATH" PATH="/usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin:/usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin:/usr/src/grass_trunk/dist.x86_64-w64-mingw32/scripts:/usr/src/grass_trunk/dist.x86_64-w64-mingw32/lib:/usr/src/grass_trunk/dist.x86_64-w64-mingw32/lib:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/c/ProgramData/Oracle/Java/javapath:/c/Windows/system32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0:/c/Program Files (x86)/Skype/Phone" LC_ALL=C /usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin/i.segment.exe --html-description < /dev/null | grep -v '</body>\|</html>' > i.segment.tmp.html ; fi
C:/msys64/usr/src/grass_trunk/dist.x86_64-w64-mingw32/bin/i.segment.exe: error while loading shared libraries: libgrass_imagery.7.1.svn.dll: cannot open shared object file: No such file or directory
../../include/Make/Html.make:14: recipe for target 'i.segment.tmp.html' failed
make: *** [i.segment.tmp.html] Error 1
rm i.segment.tmp.html

This error appeared previous, I go to C:\msys64\usr\src\grass_trunk\include\Make\ Html.make#14 and comment line14:
#	if [ "$(HTMLSRC)" != "" ] ; then $(call htmldesc,$<,$@) ; fi
Then run make in this folder, no error reported, and i.segment can be start via GRASS GUI or i.segment --ui itself.

Do you know will it be anything wrong in the future if commenting this line? 
Thanks again for the help.

as already mentioned in an earlier reply, please delete

from your local package.sh
