comandline tool for c backend
PBCEX tools to facilitate using inline c and to make precompiled static libs
Author idle 2022
Version 1.0 for windows purebasic 6.00 c backend
Linux and Raspberry PI version will be on their way
It's my hope that Fred will eventually add this to the c backend.
Set up: Compile gcc and polink to the source folder. navigate to your purebasic compilers directory and rename Gcc and polink to gcc_real and polink_real copy your compiled gcc and polink to the purebasic compilers directory.
Use:
The tool facilitates you to control gcc compiler flags and utilize c libs directly in PB and also make precompiled libs to save compile times flags are entered as inline c comments !// followed by command and argments that end in ;
!//gccflags -O3; optimize to O3
!//useclang; if you've installed mingw64 and added the enviroment path to the compiler you can use that in place of the supplied gcc
!//#include path\to\some\clibheader.h; ;this will inlude the entire c lib so it's available to use with inline c
!//makestatic path\to\your\libray.a; ;this will generate a static lib all function marked as procedureCDll will be exported
Some examples make use of llvm mingw64 you can download it here and install c:\ or where ever

;Edit your environment PATH variable to include the paths
c:\llvm-mingw-20211002-msvcrt-x86_64

Examples *Note you will need to modify all the inline c paths used on all examples and use c backend for compile
librb - ringbuffer as a static lib.
portaudio - ffttest and dueltest requires librb.a
raylib4 - screen and julia set.
miniaudio - single header c lib compiled as dll coming native to PB
librb a static lib example librb.a allows you to create a static lib and compile as a dll the file patern used allows you to easily work on and precompile a lib and use it in a project easily. Set compiler to c backend, set to the compile type to shared dll, turn off debuger and hit F5 to compile to static lib
files:
librb.a the generated static lib compiled with optional !//useclang;
librb.dll the compiled dll from using create executable
librb.lib the import lib to the dll
testlibrb.pb test for librb compile as thread safe for debug messages
ringbuffer.pbi lockfree ring buffer to produce librb.a
Notes the filepattern used in ringbuffer.pbi facilitates you to easily create test and use precompiled libs in a project to save compile times while the static libary generated is usable with pb it may not be usable from another language as it misses out the intialization functions also note that while the generated static libries are large, the resultant executable won't be anywhere near as large.
Example PortAudio
Portaudio x64 build only uses gcc as compiler
Dueltest ;example of bridging streams via a ring buffer from two threads (note you need to build the ring buffer librb first)
FFTtest ;uses a single callback on the input output streams and runs an FFT iFFT
Example Raylib4
Raylib4 x64, requires Mingw64 to be installed
Screen basic hello world example
juliaset creates an anmiate fullscreen juilia set fractal with glsl shader
Example MiniAudio x64 build of miniaudio requires mingw64 install miniaudio_duplex test recoreding from defalt mike and plays back on default speaker
