Compile error on Raspberry Pi 2

[diogomsantos]

I am getting this error compiling apkenv on Raspberry Pi 2:

...
-e CC linker/strlcpy.o
-e CC linker/dlfcn.o
-e CC compat/gles2_wrappers.o
In file included from compat/gles2_wrappers.c:4:0:

makefile:84: recipe for target 'compat/gles2_wrappers.o' failed

Any ideas ?

What is the code surrounding line 49 in /opt/vc/include/GLES2/gl2.h?

try disabling the -DGLchar=char option (in platform/YOURPLATFORM.mk)

[diogomsantos]

There is no platform for RPi 2. Maybe pandora ? But there is no -DGLchar=char in platform/pandora.mk...

[krnlyng]

you probably have to create a new platform makefile, it can be set in config.mk (PLATFORM)

[diogomsantos]

I do not have the knowledge to create the platform.mk for the raspberry pi 2 but i can provide any info if needed to the developers.

[enen92]

A specific build for the pi 2 would indeed be very cool

[krnlyng]

@enen92 @diogomsantos check out https://github.com/krnlyng/apkenv/tree/beaglebone this should be also usable to build for the rpi 2 (BUT: it does not work yet)

[diogomsantos]

Sorry for the late response, have been some days out.
@krnlyng tried your beaglebone branch but I got the exactly same error.
I just cloned your branch and did BEAGLEBONE=1 make, should I use anything else ?

[krnlyng]

sorry i was away too. you have an incorrect command line, it is supposed to be: PLATFORM=beaglebone make

[diogomsantos]

It passed the gles error but now I get this:

Beaglebone is armv6 right? Raspberry Pi 2 is armv7 maybe thats the problem.

[krnlyng]

please try my rpi2 branch: https://github.com/krnlyng/apkenv/tree/rpi2
compile with: PLATFORM=rpi2 make

[diogomsantos]

I tried to change platform/rpi2.mk to LDFLAGS += -lSDL_mixer but with the same error. Dont know if SDL2_mixer is really needed, it is not on Raspbian repos, but I have SDL_mixer installed and SDL_mixer.h by default is in /usr/include/SDL/SDL_mixer.h. I can try to compile SDL2 Mixer if it is really needed.

[krnlyng]

@diogomsantos: can you install SDL2 and SDL2_mixer from the default repositories? also the devel packages. for beaglebone these were available so i figured it should work for the rpi2 too, if not we have to rewrite a little bit of the platform code, but not much
EDIT: maybe join #apkenv on freenode

I'll close this issue the next time I'll go through the list of open issues if there's no progress here.
