我有一个包含源文件的项目（每个func也有一个.h）：
我在test_functions.c中为func3.c中定义的函数获取了未定义的引用。
到目前为止的步骤：
make VERBOSE=1显示构建func3.c并链接func3.c.o nm func3.c.o显示符号已定义readelf -s func3.c.o显示符号也已定义make VERBOSE=1显示正在使用gcc，而不是名称重整问题这里有趣的地方，我狂野地移除了func3.c重新编译，现在我得到了func3的明确引用（显然），现在也是对func2的未定义引用！ ！但是我之前已经用这个函数编译过了！
如果我将func3.c添加回来源，请将功能调用注释为func3()我可以致电func2()就好......我完全失去了。

答案 0 :(得分：0)
这是经典的PEBCAK。如果你仔细查看编译行，那么rplink-path后面没有路径。我猜gcc链接器将下一个目标文件作为rplink-path的参数附加。
