Batch checking library functions

2016-07-16

xmake provides some api, which can detect whether exist some library functions.


target("test")

    -- checks some libc functions from the header files: wchar.h and stdlib.h
    add_cfuncs("libc", nil,         {"wchar.h", "stdlib.h"},            "wcscat",
                                                                        "wcsncat",
                                                                        "wcscpy",
                                                                        "wcsncpy",
                                                                        "wcslcpy",
                                                                        "wcslen",
                                                                        "wcsnlen",
                                                                        "wcsstr",
                                                                        "wcscasestr",
                                                                        "wcscmp",
                                                                        "wcscasecmp",
                                                                        "wcsncmp",
                                                                        "wcsncasecmp",
                                                                        "wcstombs",
                                                                        "mbstowcs")

    -- checks the interfaces: pthread_mutex_init, pthread_create in the pthread
    -- the first argument is the library alias name
    add_cfuncs("posix", nil,        "pthread.h",                        "pthread_mutex_init", "pthread_create")

    -- checks the pthread interfaces and attempt to links it using flags: -lpthread
    add_cfuncs("posix", "pthread",  "pthread.h",                        "pthread_mutex_init", "pthread_create")

We can run xmake f -v to get the verbose info:

xmake will generate the results into the config.h after checking if the config file has been enabled.

target("test")
    -- set the auto-generated config.h
    set_config_h("$(buildir)/tbox/tbox.config.h")
    set_config_h_prefix("TB_CONFIG")

And the content of config.h is:

Please use the following api if we want to check the c++ function in the static library.

add_cxxfuncs(...)
