Building SITL

Linux and FreeBSD:

Almost like normal, ruby, cmake and make are also required. With cmake, the option "-DSITL=ON" must be specified.

mkdir build_SITL
cd build_SITL
cmake -DSITL=ON ..
make

Windows:

Compile under cygwin, then as in Linux. Copy cygwin1.dll into the directory, or include cygwin's /bin/ directory in the environment variable PATH.

If the build fails (segfault, possibly out of memory), adding -DCMAKE_BUILD_TYPE=MinRelSize to the cmake command may help.

Build manager

ninja may also be used (parallel builds without -j $(nproc)):

cmake -GNinja -DSITL=ON ..
ninja

Compiler requirements

  • Modern GCC. Must be a real GCC, macOS faking it with clang will not work. GCC 10 to GCC 13 are known to work.
  • Unix sockets networking. Cygwin is required on Windows (vice winsock).
  • Pthreads

Supported environments

  • Linux on x86_64, ia-32, Aarch64 (e.g. Rpi4), RISCV64 (e.g. VisionFive2)
  • Windows on x86_64
  • FreeBSD (x86_64 at least).
