Users invoke a language-specific driver program (gcc for C, g++ for C++, etc.), which interprets command arguments, calls the actual compiler, runs the assembler on the output, and then optionally runs the linker to produce a complete executable binary.

I would like my compiles to exclude some code depending upon the flash/program space available. To be used in the demo code of a library I support. Whereas my current solution is to use a #ifdef of processor type. But I would like to be more general…

I'd like to write my sketches so that I can either build/upload them using the Arduino IDE, or optionally using GCC and a makefile. I know about including the function declarations at the top, but is there anything else to do in order for my sketch…

Accessing a C++ static variable from gcc inline asm

For some reason I want to mix a bit of assembly with C++ (not C). To allow the code to be compilable using the standard Arduino IDE, I don't want to use direct assembly source. I don't want to use a wrapper C file either. My problem is as follows: I…

Works with gcc, not with Arduino. error: taking address of temporary array

I need to hard code 8 byte addresses into char arrays of length 8. This must be done many places in my code (in function scope), so I have tried to come up with a one-liner. The following works perfectly in C when compiling with gcc. char…

I'm trying to use Atom as an IDE for arduino and arduino-based boards. I'm using arduino-cli for compilation and avrdude for upload, and now I'm trying to use linter-gcc for linting. g++ is running and the linter seems to be working ok, but it's…

How do I make Arduino IDE use a specific version of GCC in Debian?

Using Raspbian Stretch. I installed gcc-4.9 with specified version. Then I installed arduino (2.1.0.5) which in turn pulled gcc 4.6. When I try to compile Marlin in it, it says Marlin requires C++11 support (gcc >= 4.7, Arduino IDE >= 1.6.8). …

using references to SFRs in gcc inline assembler

I want to write a driver that can use either timer0 or timer2, based on a choice made at compile time. So I want all references to timer registers to be abstracted, e.g. OCRA for OCR0A/OCR2A, etc. I could do it with plain macros, like so: #define…
