Title: Error 2 when compiling
Post by: ggrif on December 17, 2017, 09:54:50 pm

Finally trying to learn how to compile Next, need a little help please.  Non-coder btw, this is all greek to me!

Followed instructions in the Wiki, tried compiling 16.09 and got this far:

...

next is currently broken on windows because of a msys2 dependency issue.

I'll try to come up with a workaround tomorrow.

Thanks. But please, no rush or pressure, from me anyway.

At this point this is simply an intellectual exercise for me.

Glad I didn’t just make another mistake!!

If you disable osg/osgearth GCS should compile fine.

Edit the Makefile at the root of the LP checkout and find the following section:

else ifeq ($(UNAME), Windows)
    UAVOBJGENERATOR := $(BUILD_DIR)/uavobjgenerator/uavobjgenerator.exe
    GCS_WITH_OSG      := 1
    GCS_WITH_OSGEARTH := 1
    GCS_COPY_OSG      := 1
    GCS_WITH_GSTREAMER := 0
    GCS_COPY_GSTREAMER := 0
endif

In there, simply change the 1s into 0s and do a clean build.

OK, thanks 
I'll see if I can figure out how to do this.  Should be interesting.

Actually, just setting GCS_WITH_OSGEARTH to 0 should be enough.
