I’ve been trying unsucessfully for the last few days to get buildroot to build in a Nix Shell. The first problem I hit is that buildroot hardcodes that file must be in /usr/bin which pushed me to use a buildFHSUserEnvBubblewrap. In order to get make menuconfig to work I had to add /usr/include to C_INCLUDE_PATH and now that seems to work. I’ve been trying different combinations of wrapped/unwrapped compilers and binutils and it seems like using the wrapped version gets me furthest but neither work. The current build error is something to do with timezone_t but I’ve been in states where the issue is O_BINARY is undefined.
Has anyone gotten buildroot to work successfully in nix? Am I headed in the right direction? Does anyone have suggestions for other approaches that I’m not taking?
If anyone is interested, the nix expression I’ve been using is here, it’s probably got some unnecessary stuff in since I’ve been actively trying a bunch of different things. The current build error I’m seeing is below:
