cDetect is a tool to help you port software to different platforms.

cDetect detects the existence of features and tools at built-time.

• Detected features includes functions, types, header files, and libraries.
• Detected tools includes the compiler, the shell, and similar built tools.

cDetect only needs an ANSI C compiler to run.

All your customized detection code is written in ANSI C.

Example

The following code

#include "cdetect.c"

int main(int argc, char *argv[])
{
  config_begin();

  if (config_options(argc, argv)) {

    config_check_compiler();
    config_check_kernel();
    config_check_cpu();

    config_check_type("long long");

    if (config_check_header("stdio.h")) {
      config_check_function("snprintf");
      config_check_function("vsnprintf");
      config_check_function("asprintf");
      config_check_function("vasprintf");
    }
  }

  config_end();
  return 0;
}

produces the following output
