Hi Fab
I have managed to compile 6224
I could not compile previously because I needed to take the oculars, satellites
and telescope modules out.
other problems found
No sound, I need sound for scripts
Nebulae textures did not display. I checked the log file and stellarium was
trying to load them from
users/barry/appdata/roaming/stellarium/nebulae/default/nebulae/default
instead of
users/barry/appdata/roaming/stellarium/nebulae/default/
Placing the textures into the seeking folder allowed loading.
All these will need to be fixed before 0.13.x is released

OK, I found some time due to bad weather...
Qt5.1 comes only preconfigured in OpenGL configuration. Apparently Qt devs
have changed their minds about the importance of ANGLE on Windows given
current mainstream hardware (not caring for computers of 2011). Either
build 5.1 from sources or wait for 5.2 scheduled for November. I
downgraded to Qt5.0 (offline windows installer,
qt-windows-opensource-5.0.2-mingw47_32-x86-offline.exe) and tried my luck
up to the point where it again compiles&links successfully. After patching
the CMakeList.txt to find and link libEGL and libGLESv2 and adding some
diagnostics to StelPainter, I am stuck again. Now the version returned is
QFlags(0x800), i.e. OpenGLES 2.0. OK, this means ANGLE.
My CMakeList patch is very dirty and depends on the installed Qt system,
so I should rather not commit it. Qt forum indicates a solution is in the
works for Qt5.2.
Logs attached. The shader linker fails with "warning X3206: implicit
truncation of vector type." If I start Stellarium configured in fullscreen
mode, there is no window, but the process is visible in the task bar. If I
configure it non-fullscreen, there is a definite program crash and clearer
diagnostics, indicating that this shader code currently makes trouble with
ANGLE. I may look into it a bit more, but am no expert both in GLSL and
cmake files.
Kind regards,
Georg
