Makefile - 如何修复 libc 依赖性？

Question

我想将 Tk 静态链接到我的代码中。由于依赖性，我遇到了麻烦。我对 Makefile 所做的修改是：

TK_LIBS_64 = \
    -L/usr/X11R6/lib64 \
    -lX11 \
    -lXss \
    -lXext \
    -L/usr/X11R6/lib64 \
    -lXft \
    -lX11 \
    -lfontconfig \
    -lfreetype \
    -lxmlparse \
    -lexpat \
    -L/usr/X11R6/lib64 \
    -lXrender  \
    -lpthread \
    -ldl \
    -lpthread \
    -lieee \
    -lm

LIBS64 = \
    -L$(TCL_ROOT)/lib/ -ltk8.5 \
    $(TK_LIBS_64)

编译时出现以下错误：

未定义的引用位于 libc.a 或 libc_p.a 中，将它们添加到依赖项中没有帮助。由于未定义的引用是系统调用，我想我在这里遗漏了一些基本的东西。如果有人能指出错误，我将不胜感激。

使用 -pthread 而不是 -lpthread
