Compile modified mupen64core

[TheCherry]

Hallo,

i have to compile a modified mupen64core to RPI for our Modloader64 project.
Its a COOP launcher for games like Zelda oot and mm, banjo kazooie, dk64 and more.
Is all what I need this script? https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/mupen64plus.sh
And is it able to cross compile the core?
Can I just take the video, input and sound plugins from a installed retropie system?

Greetings

I tried to compile the mupen64core. But I get every time the error

#error SDL is not build with OpenGL support. Try USE_GLES=1
 ^
Makefile:784: recipe for target '_obj/api/vidext.o' failed

And I tried a lot of things with SDL now, the Version 1 and 2
Precompiled for RPI and self compiled the default version and a extra version for RPI.
I tried at last this configure:

./configure --host=arm-raspberry-linux-gnueabihf --enable-video-opengl --disable-video-x11 --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland

@TheCherry said in Compile modified mupen64core:

USE_GLES=1

Have you tried putting this on the command line when you compile (i.e on the end of your "make" command).

The hint is right there.

@ledow sure ... but its give me the same result.

That was my last try:

make V=1 VC=1 USE_GLES=1 CROSS_COMPILE=/opt/toolchain/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- all 

/opt/toolchain/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-gcc -O3 -flto -Wall -ffast-math -fno-strict-aliasing -fvisibility=hidden -I../../src -I../../src/asm_defines -DM64P_PARALLEL -fPIC -I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/vmcs_host/linux -I/opt/vc/include/SDL2 -DNDEBUG -I../../subprojects/md5 -I../../subprojects/xxhash -DDYNAREC -MD -MP   -c -o _obj/api/vidext.o ../../src/api/vidext.c

personally, if i was doing this i would make a fork in github with my changes, and then edit the retropie build script to point at it, then compile it through retropie - update via source.

eg https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/mupen64plus.sh#L32

if i made a change to the master branch of my fork of mupen64plus-core, i would this line to
'dankcushions core'

note that when you edit retropie scripts the script updater will complain when you come to update it.
