undefined reference to “functionA” 在既有的一个c库基础上(c源代码),开个jni接口给Android App使用,竟然折腾了两个小时,郁闷死我了。不过总算搞定了,呵呵。 有个顽固的错误,搞得我不知所措,最后发现竟然是因为我的jni代码后缀cpp,而c库中分开放接口的头文件没有加可被c++使用的申明,导致出现“undefined ref...
test.a(test.o): In function `test': test.c:(.text+0x13): undefined reference to `func' collect2: ld returned 1 exit status 因此,我们需要注意,在链接命令中给出所依赖的库时,需要注意库之间的依赖顺序,依赖其他库的库一定要放到被依赖库的前面,这样才能真正避免undefined reference的错误,完成编译链接。
1. /tmp/ccCPA13l.o: In function `main':2. main.c:(.text+0x7): undefined reference to `test'3. collect2: ld returned 1 exit status 其根本原因也是找不到test()函数的实现⽂件，由于该test()函数的实现在test.a这个静态库中的，故在链接的时候需要在其后加⼊test.a这个库，链接命令修改为...

4.gcc "undefined reference to" 问题解决方法 5.Linux gcc链接动态库出错:LIBRARY_PATH和LD_LIBRARY_PATH的区别 1.linux下查找库文件所在位置 ldconfig -p | grep libcrypto 1. glibc的库版本号查询 因为ldd命令也是glibc提供的,所以也能查看 ldd --version ...
/tmp/ccJjiCoS.o: In function `main': main.cpp:(.text+0x7): undefined reference to `test()' collect2: ld returned 1 exit status 原因就是main.cpp为c++代码,调用了c语言库的函数,因此链接的时候找不到,解决方法:即在main.cpp中,把与c语言库test.a相关的头文件包括加入一个extern "C"的声明就...
You need to properly qualify that xora() is part of the class and that it is not just a function in the global scope. int decof::xora(int q, int i) But really there is not much point of our class since it doesn't have any class member variables. I also suggest you start us...
Then the linker creates the executable by combining the object files (and libraries). If your project is not set to compile every .cpp and link all the results, or if no .cpp provides implementation for function, then you get the undefined reference. Dec...
