sudo make install on pi zero doesn't get past glfwGetProcAddress #31

Closed techmaticsnz closed 3 years ago

techmaticsnz commented 3 years ago

is this a typo?

it recommends changing it to eglGetProcAddress

This looks like an issue with the original C library, Raylib, rather than the Raylib Python CFFI bindings so suggest you report it to Raylib's GitHub and/or Discord.

techmaticsnz commented 3 years ago

Got it. thanks!

:79:1: Directives not supported yet ` I've placed a compiled library libraylib.a file in /usr/local/lib as per the build file
electronstudio commented 3 years ago

The build error is caused by the patch failing, which is due to the file being missing. I have added the missing file if you do a git pull.

electronstudio commented 3 years ago

The /usr/local/lib/libraylib.a file should be installed when you compile and install Raylib, you shouldn't have to put it there yourself. If you haven't compiled and installed Raylib yourself you may hit other issues.

electronstudio commented 3 years ago

btw once you get it to build, if you send me the dist/raylib*.whl file I will put it on pypi so other Pi users dont need to go through the hassle of building.

electronstudio commented 3 years ago

I haven't ever used Raylib on Pi, only @simonchatts has reported it works. I have an old RPi3, I will give it a go on that.

electronstudio commented 3 years ago

before you build Raylib you have to do:

sudo apt install libasound2-dev mesa-common-dev libx11-dev libxrandr-dev libxi-dev xorg-dev libgl1-mesa-dev libglu1-mesa-dev
electronstudio commented 3 years ago

I think the reason you're not getting the librarylib.a file is that the BUILD_SHARED_LIBS flag prevents the static libs from being built. I'm sure it used to build both. I will remove that flag. We don't need the shared libs with raylib.static anyway, they are only for raylib.dynamic

electronstudio commented 3 years ago

and there's an error in my RPI build script, my fault, now fixed

electronstudio commented 3 years ago

OK, instructions have been updated, bug has been fixed, (thanks for reporting) and it works on my RPi3.

Here is the wheel file. raylib-rpi3.tar.gz You can install it with:

tar xvfz raylib-rpi3.tar.gz
pip3 install raylib-rpi3/raylib-3.7.0-cp35-cp35m-linux_armv7l.whl

(I also had to upgrade my version of pip to get this to run)

Now the question is, is this binary likely to work on other RPi3 installs, and is it likely to work on other models?

techmaticsnz commented 3 years ago

Thank you very much! trying the wheel now

techmaticsnz commented 3 years ago

The wheel file didn't run on pi 0

techmaticsnz commented 3 years ago

now im getting this patch -p0 <raylib_modified.h.patch File raylib.h is not a regular file -- refusing to patch 7 out of 7 hunks ignored -- saving rejects to file raylib.h.rej

I had to git pull on raylib-c in order to get the build to work.

electronstudio commented 3 years ago

looks like there's something wrong with the patch file, i will fix it later.

the patch step is actually optional and not required. could you try:

  1. delete everything
  2. checkout from github again
  3. follow instructions again but skip the 2 steps i have now marked 'optional'.
electronstudio commented 3 years ago

the patch file should be fixed now, but still easier just not to do patching at all, since it isn't required unless you update to a newer than 3.7 raylib.

That’s very strange. I would guess it’s some kind of version mismatch. We are expecting Raylib version 3.7 - that’s what you will find in the raylib-c sub folder after checkout. But your raylib.h looks like a different version, possibly the latest version from GitHub. Did you replace Raylib 3.7 with a different version?

Maybe you did a git pull on Raylib and updated it to a newer version?

could you try deleting everything and following the instructions again from the beginning?

Please reopen if you are still having issue.
