This is a Debian-based 32-bit Linux distribution developed by the Raspberry Pi Foundation. Raspberry Pi runs on its own operating system called Raspberry Pi OS (formerly Raspbian). If your project doesn't exit you can use CTRL+SHIFT+C to forcibly exit it in LXTerminal.It's this democratization of Pi that ultimately laid its foundation as a device that's now widely used by many to learn about concepts of computers, electronics, and other hardware verticals. your project uses the IO pins) then run it as the root user by using "sudo. If you get a permissions denied error (i.e. Run the exe by typing "./output_file_name.a" Using LXTerminal change to your project directory (e.g. Go to the projects directory and enter the command: Running Make from the command line instead of in Geany You have a C++ project and need to select g++ instead of gcc in two places in the makefile (or you can sometimes add this -lstdc ++ to the makefile LIBS= if you want to use gcc) Lots of errors like this: "undefined reference to `std::allocator::allocator()'" Make will not work properly if it's not there. There must be a tab (not spaces) at the beginning of any command. There is a tab before the gcc or g++ command in the makefile. If not Geany will build that source file instead using its default settings but it won't give you an error message to tell you its doing that. $(CC) -c -o $ Build > Make (SHIFT+F9) to cause Geany to run the makefile and if no errors are found it will produce your exe ready to run.Įnsure your makefile is saved if you've made any changes! #define a rule that applies to all files ending in the. #Set the filename extensiton of your C files (e.g.c or. #Set the compiler you are using ( gcc for C or g++ for C++ ) I/usr/include/somefolder `pkg-config -cflags gtk+-3.0` ), or leave blank #Set any compiler flags you want to use (e.g. lbcm2835 -lrt `pkg-config -libs gtk+-3.0` ), or leave blank #Any special libraries you are using in your project (e.g. main.h some_subfunctions.h some_definitions_file.h ), or leave blank #Set any dependant header files so that if they are edited they cause a complete re-compile (e.g. #Set all your object files (the object files of all the. #Change output_file_name.a below to your desired executible filename #This sample makefile has been setup for a project which contains the following files: main.h, ap-main.c, ap-main.h, ap-gen.c, ap-gen.h Edit as necessary for your project Just copy the following into a new file and save it as "makefile" in your projects folder, then edit the settings for your project. This is a more powerful solution to use instead based on excellent examples here. The "-lbcm2835" assumes you are using the Mike McCauley bcm2835 library for IO control, if not just remove it.Ī really useful makefile for geany C or C++ projects Make will not work properly if it's not there.Īn example simple makefile for a project with a single file called main.c, to show you the basics of what a makefile does: Important note – there is a tab before the gcc or g++ command in the makefile. Geany's "make" command will use the make file called "makefile" by default, so you can simply give your makefile that name and save it in the same folder as your project files. To solve this you need to use a makefile. Geany doesn't compile projects it compiles files. Its worth getting straight into using a makefile so that using multiple files in a project is really easy. However as you will see if you try and compile the sample blink project code above, changes are already needed to include the bc2835 library object file. This can be all you need for simple projects or where you edit the Geany project build properties. Give the project a name and choose where to save it.Īs a good starting point copy the bcm2835 blink project sample code into your new main.c file and connect a LED positive pin to Pin 11 of your RPi P1 header:īcm2835_gpio_fsel(PIN, BCM2835_GPIO_FSEL_OUTP) Ĭompile – Compile the currently selected source file into a binary object file.īuild – Link the currently selected source files object file into an executable (compile it first if the object files don't exist)
