我正在尝试通过遵循教授所做的步骤来编译一个简单的代码，但是我

cc     calculator.c   -o calculator
/usr/bin/ld: /tmp/ccznJMZB.o: in function `main':
calculator.c:(.text+0x19): undefined reference to `get_int'
/usr/bin/ld: calculator.c:(.text+0x2d): undefined reference to `get_int'
collect2: error: ld returned 1 exit status
make: *** [<builtin>: calculator] Error 1

使用的是Linux Mint BTW的问题，已经在安装CS50库时遇到了问题，但这已经完成了。我很乐意收到一个新的错误，但是我需要修复它。谢谢！

i'm trying to compile a simple code by following the steps that the professor made but I have this issue

cc     calculator.c   -o calculator
/usr/bin/ld: /tmp/ccznJMZB.o: in function `main':
calculator.c:(.text+0x19): undefined reference to `get_int'
/usr/bin/ld: calculator.c:(.text+0x2d): undefined reference to `get_int'
collect2: error: ld returned 1 exit status
make: *** [<builtin>: calculator] Error 1

I'm using Linux mint btw, already had problems installing cs50 library but that's done. I'm happy to get a new error tho, but I need to fix it.
Thanks!

参见 https://cs50.readthedocs.io/libraries/cs50/cs50/c/

要使用这些功能，请确保包括#include＆lt; cs50.h＆gt;在您的文件上方并使用-LCS50 flag进行编译。
。

#include＆lt; cs50.h＆gt;需要标题文件cs50.h在编译器的包含路径中。

#include“ cs50.h”期望标题文件cs50.h与您的.c .c文件处于同一目录。

上面的链接还告诉您如何安装库：

$ curl -s https://packagecloud.io/install/repositories/cs50/repo/script.deb.sh | sudo bash
$ sudo apt install libcs50

故障排除
如果编译程序时，您会看到：
/usr/bin/ld：找不到-lcs50：
将导出library_path =/usr/local/lib添加到您的.bashrc。
致命错误：未找到'CS50.H'文件：
添加导出c_include_path =/usr/local/include indor your .bashrc。
无法打开共享对象文件：没有这样的文件或目录：
将fort ld_library_path =/usr/local/lib添加到.bashrc。

See https://cs50.readthedocs.io/libraries/cs50/c/

To use these functions, make sure to include #include <cs50.h> atop your file and compile with the -lcs50 flag.

#include <cs50.h> requires the header file cs50.h to be in the include path of your compiler.

#include "cs50.h" expects the header file cs50.h to be in the same directory as your .cfile.

The link above also tells you how to install the library:

$ curl -s https://packagecloud.io/install/repositories/cs50/repo/script.deb.sh | sudo bash
$ sudo apt install libcs50

Troubleshooting
If when compiling your program, you see:
/usr/bin/ld: cannot find -lcs50:
Add export LIBRARY_PATH=/usr/local/lib to your .bashrc.
fatal error: 'cs50.h' file not found:
Add export C_INCLUDE_PATH=/usr/local/include to your .bashrc.
cannot open shared object file: No such file or directory:
Add export LD_LIBRARY_PATH=/usr/local/lib to your .bashrc.
