armhf linux build failure. about ppsspp

[kivutar]

When you're getting this kind of errors, it means you-re trying to compile with your own g++, not the cross compiler.

[orbea]

Yes, its hardcoded to g++, but its hard to fix blindly...

[kivutar]

In Lakka, I build it using this https://github.com/libretro/ppsspp/blob/master/libretro/Makefile#L100-L112

Or like this

make platform=armv-gles-neon CC=$CC CXX=$CXX

[gouchi]

We should try to remove the hardcoded version and use the correct ones which are present in the default configuration ?

[orbea]

Thanks for taking a look at this!

[gouchi]

No problem, you are welcome.

New log after specifying CC and CXX.

[orbea]

I suppose there is a problem with the ffmpeg submodule included, its missing or the Makefile is not using it for some reason?

[gouchi]

Not sure if it is related to this include flags as it is not present elsewhere.

[orbea]

@gouchi Mind making an issue for an more current repo?

[orbea]

Here is a new build log.

[gouchi]

We should not get

/ffmpeg/linux/x86_64/include

The compilation starts with

make -f Makefile platform=unix -j6 platform=armv7-neon-hardfloat ARCH=arm CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ clean

There are two platform variables.

[orbea]

Looks like that is a buildbot issue, I'll try to figure out where the extra platform=unix is coming from.

[orbea]

platform=armv7-neon-hardfloat is set in the recipe.

ppsspp libretro-ppsspp https://github.com/libretro/ppsspp.git master YES GENERIC_GL Makefile libretro platform=armv7-neon-hardfloat ARCH=arm CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++

https://github.com/libretro/libretro-super/blob/master/recipes/linux/cores-linux-armhf-generic

and platform=unix is in the buildbot script.

eval "set -- ${HELPER} ${MAKE} -f ${MAKEFILE} platform=${PLATFORM} -j${JOBS} ${CORE_ARGS}"
echo "BUILD CMD: $@" 2>&1 | tee -a "$LOGFILE"
"$@" 2>&1 | tee -a "$LOGFILE"

New log after this commit.

CPUFLAGS are wrong they are coming from Makefile.common from here because TARGET_ARCH is not arm.

I will be glad to know why there are those lines in the beginning of the Makefile.
