4 Almost like normal, ruby, cmake and make are also required.
5 With cmake, the option "-DSITL=ON" must be specified.
15 Compile under cygwin, then as in Linux.
16 Copy cygwin1.dll into the directory, or include cygwin's /bin/ directory in the environment variable PATH.
18 If the build fails (segfault, possibly out of memory), adding `-DCMAKE_BUILD_TYPE=MinRelSize` to the `cmake` command may help.
22 `ninja` may also be used (parallel builds without `-j $(nproc)`):
25 cmake -GNinja -DSITL=ON ..
29 ### Compiler requirements
31 * Modern GCC. Must be a *real* GCC, macOS faking it with clang will not work. GCC 10 to GCC 13 are known to work.
32 * Unix sockets networking. Cygwin is required on Windows (vice `winsock`).
35 ## Supported environments
37 * Linux on x86_64, ia-32, Aarch64 (e.g. Rpi4), RISCV64 (e.g. VisionFive2)
39 * FreeBSD (x86_64 at least).
