“undefined reference to XXX”是一类挺常见的链接错误,原因通常是链接时找不到声明成extern类型的函数的定义点。不过这次遇到的undefined reference中的XXX函数明明在一个库中定义,而且该库明明已经在命令行用-l指定了,ld –verbose也显示能找到该库文件。 Table of Contents 1 快速解决方案 2从extern说起 3 链接...
说道undefined reference error,先提一下Linux gcc链接规则: 链接的时候查找顺序是: -L 指定的路径, 从左到右依次查找 由 环境变量 LIBRARY_PATH 指定的路径,使用":"分割从左到右依次查找 /etc/ld.so.conf 指定的路径顺序 /lib 和 /usr/lib (64位下是/lib64和/usr/lib64) 动态库调用的查找顺序: ld的-...
看到这里,你也就知道了由于上面三个虚函数没有被实现,所以会有undefined reference to `vtable for * * * '这种错误。 4. 小结 认真生活, 努力感悟!

(.text+0x24): undefined reference to `main' collect2: error: ld returned 1 exit status 在使用g++编译链接两个C++源文件main.cpp以及VecAdd.cpp时出现了以上编译报错。main.cpp中引用了VecAdd.cpp中定义的函数vecAdd来实现两个向量的加法。我们先说原因,再来分析一下g++为什么会报这样的错误。出现这个error...

我在使用SDL2的时候,遇到undefined reference to `SDL_Init'的问题,只要使用SDL2相关的函数,就会报函数未定义。后来百度到一篇文章https://blog.csdn.net/hank12580/article/details/45949995,经过测试可以使用,原来是编译的时候后面要加一些参数,具体我不知道是干啥的,至少给了我一个方向,我应该去看看SDL2相关的教...
Without minimal example it is hard to tell, but I think that linking is source of your problem. Look at these two stacks: https://stackoverflow.com/a/61085569 https://stackoverflow.com/questions/27672572/embedding-python-in-c-linking-fails-with-undefined-reference-to-py-initialize...
Hi @Hrohn It seems like you are facing an issue with the linker not finding the reference to the `ceilf` function. To resolve this issue, you need to add the math library to your project's linker settings. Here's how you can do that: In S32 Design Studio, right-click on your proj...
