Look in config.log and work out the name of the compiler. Fix in .../build-data/platforms/x86_64.mk or override from the command line.

There are several examples. Note the rule: xxx_native_tools = vppapigen This rule builds the missing build-host tool. Then: “make PLATFORM=xxx TAG=xxx_debug vpp-install” or similar. Caveat: the main Makefile “.../build-root/Makefile” is non-trivial. In the past, we’ve used it to self-compile full toolchains, and to use the resulting toolchains to cross-compile embedded Linux images with squashfs / unionfs disk images. All of the mechanisms are there to do interesting things, but since we seldom do those things anymore you can expect a certain amount of trouble.

Initially, I did the following: CC=x86_64-rumprun-netbsd-gcc make bootstrap, but I saw the following error If you meant to cross compile, use `--host'. See `config.log' for more details As a work-around based on the config.log, I did this following /src/configure (Stripped other output ) --build=x86_64-linux-gnu --host=x86_64-rumprun-netbsd --target=x86_64-linux-gnu However, I saw the following error: checking for vppapigen... no configure: error: Externaly built vppapigen is needed when cross-compiling...
