C 链接错误（使用 tcc）

Question

我正在尝试从名为 的小型 cc (tcc-0.9.26-win64-bin.zip)运行该示例libtcc_test.c。

我已将libtcc.hfrom libtccintoinclude复制libtcc.def到lib.
然后我运行tcc ./examples/libtcc_test.c并收到链接错误：/

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'

我缺少什么？

要链接到库中，您需要在所有文件或文件-l${library_basename}后面添加一个标志。如果库被命名为或（在 Windows 上可能是或），则需要添加.colibtcc.alibtcc.sotcc.dlllibtcc.dll-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 repo 中的libtcc_test.cfrom还需要库（动态加载的标准库）来构建：test/libtcc_test.cdl

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

（它抱怨 undefined dlopen、dlclose、 和dlsym已知来自libdl）。
