C 链接错误(使用 tcc)

Question

我正在尝试运行来自 tiny cc 的示例(tcc-0.9.26-win64-bin.zip) 调用了 libtcc_test.c。

我已经将 libtcc.h 从 libtcc 复制到 include 并将 libtcc.def 复制到 库.
然后我运行 tcc ./examples/libtcc_test.c 并得到一个链接错误:/

tcc: error: undefined symbol 'tcc_new'
tcc: error: undefined symbol 'tcc_set_lib_path'
tcc: error: undefined symbol 'tcc_set_output_type'
tcc: error: undefined symbol 'tcc_compile_string'
tcc: error: undefined symbol 'tcc_add_symbol'
tcc: error: undefined symbol 'tcc_relocate'
tcc: error: undefined symbol 'tcc_get_symbol'
tcc: error: undefined symbol 'tcc_delete'

我错过了什么？

要在库中链接，您需要在所有c 文件或o 文件之后添加一个-l${library_basename} 标志。如果库名为 libtcc.a 或 libtcc.so(在 Windows 上它可能是 tcc.dll 或 libtcc.dll)，需要添加-ltcc。

tcc  ./examples/libtcc_test.c  -ltcc

您可能还需要添加一个 -L 标志来添加搜索路径，以防您要链接的库不是您系统的标准库目录:

tcc -L . ./examples/libtcc_test.c -ltcc
#also look for libtcc.so or libtcc.a in the current directory (.)

tinycc 仓库中 test/libtcc_test.c 中的 libtcc_test.c 还需要 dl 库(动态加载的标准库)构建:

tcc -L .  tests/libtcc_test.c  -ltcc -ldl #worked 

(它提示未定义的 dlopen、dlclose 和 dlsym，它们已知来自 libdl) .
