openVG test, compiler errors

[XPUIPC]

Hi,

i am trying out openVG on the raspberry (3B+) with debian and latest firmware. I am crosscompiling with MS VS 2019 and made the following settings:

includes: -I "/opt/vc/include/interface/vcos/pthreads" -I "/opt/vc/include" -I "/opt/vc/include/interface/vmcs_host"
libs: -l"wiringPi" -l"pthread" -l"bcm_host" -l"OpenVG" -l"EGL" -l"GLESv2"-L"/opt/vc/lib"

It compiles but then i get unresoved issues in EGL.lib:
1>/usr/bin/ld : error : //opt/vc/lib/libEGL.so: undefined reference to `glDiscardFramebufferEXT'
1>/usr/bin/ld : error : //opt/vc/lib/libEGL.so: undefined reference to `glPointSizePointerOES'

I browsed through several forums, also here but did not find the clue how to solve this... Is there someone who can help me here ?

Thank you

Looks like you're missing a space here:

Code: Select all

-l"GLESv2"-L"/opt/vc/lib"

So it went looking for a library called libGLESv2-L/opt/vc/lib.so and of course couldn't find plain old libGLESv2.so where those functions reside.

It's also preferred to use the newer less-ambiguous names brcmEGL and brcmGLESv2. I wonder how yours found /opt/vc/lib/libEGL.so, unless you're running on an older distro like Jessie.

Hi,

thank you for the hint. I am now using the brcm library and everything works fine…


Thank you
