configure: error: pkg-config not found
igorfuna opened this issue · comments
I'm trying to buld raylib-php on Raspberry Pi 4.
I get the following error after running ./configure
checking for raylib support... yes, shared
checking whether to enable raylib support... yes, shared
checking for pkg-config... /usr/bin/pkg-config
checking for libraylib... configure: error: pkg-config not found
Please advise.
You need the build tools first:
sudo apt install build-essential autoconf libtool bison re2c
Second, you will need to compile and install raylib itself:
sudo apt-get install --no-install-recommends raspberrypi-ui-mods lxterminal gvfs
sudo apt-get install libx11-dev libxcursor-dev libxinerama-dev libxrandr-dev libxi-dev libasound2-dev mesa-common-dev libgl1-mesa-dev
sudo apt-get install libdrm-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev
More info on Raylib on Raspberry Pi 4: https://github.com/raysan5/raylib/wiki/Working-on-Raspberry-Pi
git clone https://github.com/raysan5/raylib.git
cd raylib
git checkout tags/4.0.0
cd src
make PLATFORM=PLATFORM_DRM
sudo make install
Then you can compile the Raylib-PHP extension:
phpize
./configure
make
make install
Thank you very much for the reply.
I already had the tools and Raylib installed.
The Raylib library is located in
/usr/local/lib/libraylib.a
and works fine.
I can compile c examples and they work.
But I would like to use PHP.
pkg-config is located here:
/usr/bin/pkg-config
When I run ./configure I get

Not sure if this is important but pkg-config does not recognize raylib
If I run pkg-config raylib --libs I get
Package raylib was not found in the pkg-config search path.
Perhaps you should add the directory containing `raylib.pc'
to the PKG_CONFIG_PATH environment variable
No package 'raylib' found
raylib.pc doesn't seem to be generated, there is only raylib.pc.in in the Raylib download/compile folder.
Ah, thats most likely due to that the default build system for Raylib does not install the pkg-config files. You can try using CMake:
https://github.com/raysan5/raylib/wiki/Working-with-CMake
This will properly generate the pkg config files
