How i can compile under Devuan Ascii?

RetroArch Linux devices
#1

Hi there, again i am trying to compile Retroarch from git.

Well this time i need to specify SDL2 root dir is =/usr/local becuase the system version is too old for this release, and if i try to uninstall from synaptic, that want to broke all my system, becuase of that i had compile manually and install the latest version of SDL2 + image + ttf inside /usr/local

Because for another proyects like “solarus” engine for be build sucessfully.

#Get the source code & update it

cd /media/Compartido/Liñux/cdf/git
git clone https://github.com/libretro/RetroArch retroarch
cd retroarch
git pull
./fetch-submodules.sh

#Configure & Try make & Install

./configure \
--disable-systemd \
--enable-ffmpeg \
--enable-steam \
--prefix=/usr ; \
export {C,CXX}FLAGS='-O2 -fPIC -march=native -mtune=native -pipe' ; \
export OPTFLAGS='-O2 -fPIC -march=native -mtune=native -pipe' ; \
make

#SDL2 Fail :

make: *** No hay ninguna regla para construir el objetivo '/usr/include/SDL2/SDL_sensor.h', necesario para 'obj-unix/release/input/input_keymaps.o'.  Alto.

And well this is searching in /usr/include, and not inside /usr/local/include

cat /usr/include/SDL2/SDL_sensor.h
cat: /usr/include/SDL2/SDL_sensor.h: No existe el fichero o el directorio

cat /usr/local/include/SDL2/SDL_sensor.h

… rest of the output

why the configure not had options like cmake i need use something like :

sdl2dir=/usr/local

well thanks for any help can you give me

#2

Well i don’t remeber which thing i do to SDL2 read the right path but in Devuan i had error on ffmpeg like on Slackware 14.2

make

                    ^~

building stuff with dynamic ffmpeg in linux is almost always problematic. I would just --disable-ffmpeg for now unless you absolutely need it for some reason.

#4

i want ffmpeg support for record gameplays, because had better compression instead of use SimpleScreenRecorder. to record directly opengl and better flow / fps

Look this happen if i record using SSR (This was with retroarch 1.7.8) -> https://www.mediafire.com/file/0w92nprxvbns3fu/SSR_-_RetroArch_Contra.mp4/file

And this happend if i record directly from RetroArch (1.7.8 in this case) -> https://www.mediafire.com/file/o8rryt9g5lz2d4v/Contra_(J)_[T+Spa_Djt]-190913-174213.mkv/file

#5

What about OBS? I know some people have had good luck with it.

#6

Well the actual git version v1.8.4 can compile fine with ffmpeg :smiley: Sadly the first thing i try to record “Akumajou Dracula X : Moonlight in Nocture” aka “Castlevania : Symphony Of The Night”, Sega Saturn Version

When i try record Sega Saturn Game :

./retroarch

xD LOOL!
