I would appreciate insight on a compilation error while building GCC 11 to run on Windows, targeting bare metal ARM, from a GNU/Linux build environment (specifically Ubuntu via WSL2). I have a current (within a few days) clone of the Git repo at the HEAD of releases/gcc-11. *** Source tree: $ git status On branch releases/gcc-11 Your branch is up to date with 'origin/releases/gcc-11'. *** Build environment: $ gcc -v Using built-in specs.

Extracting the recipe steps, here is how I'm attempting to build GCC: Recipe steps: # Obtain GCC source for the release branch of interest. # # "If you do not intend to make changes to the source, you can avoid installing these build tools by running contrib/gcc_update." # https://gcc.gnu.org/git.html git clone --branch releases/gcc-11 --depth 1 git://gcc.gnu.org/git/gcc.git $(COMPILER_ROOT)/gcc cd $(COMPILER_ROOT)/gcc && contrib/gcc_update # "If you also intend to build binutils (either to upgrade an existing installation or for use in place of the corresponding tools of your OS), unpack the binutils distribution ... in the same directory..." # https://gcc.gnu.org/install/download.html # https://www.gnu.org/software/binutils/ git clone --branch binutils-2_37 --depth 1 git://sourceware.org/git/binutils-gdb.git $(COMPILER_ROOT)/gcc/binutils # "Likewise the GMP, MPFR and MPC libraries can be automatically built together with GCC.

I think these flags are only needed for a compiler that is actually running on Windows, which I am NOT doing; I am building a compiler FOR Windows. When I encountered another error, and another beyond that, I concluded that I must be making an error myself, because I doubt that a released version of GCC would have multiple errors with respect to cross compilers.

[Makefile:53: /home/tsobczynski/Compiler/build/foo] Error 2 Granting that I am proceeding from a position of ignorance, I am not expecting an attempted invocation of "arm-none-eabi-gcc". My reasoning is that the build process is taking place on GNU/Linux, while "arm-none-eabi-gcc" is the name I expect for one of the compiler executables that will run on Windows. Just prior to the error, the GCC build copies xgcc.exe to gcc-cross.exe, which I presume is the compiler executable that will ultimately correspond to "arm-none-eabi-gcc.exe". Because I don't know what I don't know here, I don't have a crisp question, except perhaps: where am I going astray in my thinking and/or build steps for the goal I'm trying to attain? Did I already go off the right track when I modified the config file earlier in the process? Thanks, Tom
