When I was trying to compile my code, I got this error from linker: undefined reference to `Serial_Init' Where Serial_Init is a function declared in a file serial_cli.h which is in the same directory and workspace. What's more, I declared some macros there, and can use them no prob...
c语言不可能是txt的扩展名 要么是c要么是h ,c用来放函数实现,h用来放函数声明,所以你main包含的时候包含.h就好了,不用包含c的文件,链接的时候把.o链接进来就好了,你这个错误是说你duiyi这个玩意没定义,也就是调用的函数没找到函数实现
It is day 3 and i am getting this linker error now though and i can't for the life of me figure out why. This is what i have in my CMakeLists.txt: cmake_minimum_required(VERSION 3.4) if ( ${CMAKE_SOURCE_DIR} STREQUAL ${CMAKE_BINARY_DIR} ) message( FATAL_...
1、是函数声明的时候用分号结束,也就是第一行 2、main函数最后缺了一个大括号“}”,或者说你把大括号放到了最最后 3、mul函数定义的时候,没有分号 4、我第一次复制你的代码时,min是灰的,不知道是不是关键字,不过我运行了,不影响 最后,我把return注释了,最后那个大括号去了(参考第2条...
I have a c library. The build works fine. Initially, it was a DLL build. but I changed it do a static library and removed the dll export things. Then I want to use this library in a C++ project.I wrapped an extern "C" around the include of the header files to eliminate name ...
main.o: In function `main': main.c:(.text+0x7): undefined reference to `test' collect2: ld returned 1 exit status 这就是最典型的undefined reference错误,因为在链接时发现找不到某个函数的实现文件,本例中test.o文件中包含了test()函数的实现,所以如果按下面这种方式链接就没事了。

源文件后缀应该是cpp而不是c 我猜你用的是c++
