./ddns4cdn -c config.tomlTips for developers using macOS:
You don't need Xcode (but still need to install command line tools) to build executables and libraries (including Swift).
I created this project without opening Xcode at all, you can do the same.
Xcode sucks. It doesn't provide a human-readable configuration file. When I search on Google for development problems about macOS, most of the results are about Xcode (even on Stack Overflow). Using the mouse to click buttons is not a good way to develop. It is not efficient and not reproducible. I don't want to use a tool that I don't know how it works.
go build -o build/ddns4cdn[.exe] ./srcSet GOOS and GOARCH to build for other platforms.
-
Mingw-w64 (GCC, required for
go build)WinLibs's build is recommended, tested with MCF and UCRT.
-
Microsoft C Build Tools (MSVC, optional)
go builddoesn't support MSVC, but you can use MSVC to build exe and dll.
GCC or Clang
go build can use GCC or Clang, set CC to switch.

# set DYLD_LIBRARY_PATH to load shared library
