Hi Guix, I’m trying to update my custom package for the Axoloti audio board, which is not yet in Guix because it depends on bundled Java jars. The package includes a user interface written in Java and a cross-compiled firmware for the board.
The latest version includes C++ sources for the firmware. Unfortunately, our “arm-none-eabi” cross-compiler package does not build libstdc++, nor does it come with any of the required C++ headers like “cmath”. So I tried to change our “arm-none-eabi” cross-compiler packages to also build and install libstdc++ but failed in a multitude of ways. The end result is always that either the compiler fails to build (e.g. when enabling libstdc++ via configure flags) or that the compiler fails to find the header files that are included via “#include_next” directives (e.g. when building libstdc++ as a separate package). Could someone with GCC experience give me a hint despite my vague problem description? -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
