Tried to build the GCS package, but continuously getting Error 2816, even I started every thing from fresh (install msys2, mingw, clone, make, etc.):

(Remark: I can build the GCS package previously.)

Msys pushed a broken binutils. See https://github.com/Alexpux/MINGW-packages/issues/3330.

They have since downgraded to the last good one.

You'll need to run 'pacman -Suuy' to fix your msys install and do a clean build of LibrePilot.

[kaycekwan]

After <pacman -Suuy>, <make all_clean>, <make package> didn't give Error 2816 but Error 2:

mingw32-make: *** [Makefile:308: gcs] Error 2

As in https://forum.librepilot.org/index.php?topic=4044.0 changed ~librepilot/Makefile to:

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

finally it compiled ok (but with a dirty word.)

LibrePilot-16.09+r589-g4c9c3c2-dirty_x86_64.exe

Thanks.

Glad you got it working.

Msys2 is a moving target, always pushing newer versions of libraries.
So things are sometimes broken (like osgearth currently).

As for the 'dirty' in the package name it indicates that your git clone contains uncommitted changes.

And no problem to generate the installer?

It seems it's looking for LibrePilot-16.09+r550-g213893e-dirty_x86_64.exe while librepilot-gcs.exe
 was generated.

[kaycekwan]

As I knew what I have changed in the code, I used the .exe generated (with a dirty word) to install and start. It starts and works alright, though I haven't yet tested each of the function of GCS.

[sam028]

All good on my side, I figured it out.
