Undefined reference to temp_file

Hello, after installing CppAD on arm architecture, I wrote a test file to test it. When I compiled it, I encountered the following error.

How did you solve your problem ? It seems from the message above that you were missing -lcppad_lib on the link line ?

Just connect the library to the terminal prompt.

Lower the Cppad version,I use the 20220000.0 and it works.

Checking version 20220000
https://github.com/coin-or/CppAD/tree/stable/20220000/cppad_lib

The temp_file utility is not in cppad_lib
https://github.com/coin-or/CppAD/tree/stable/20220000/cppad_lib

I suspect that the following answer would solve your problem in the current version:
#182

On unix systems, perhaps this is a good way to solve this problem.

1. Let prefix be the cppad_prefix; see
   https://cppad.readthedocs.io/en/latest/cmake.html#cppad-prefix
2. Execute the command find prefix -name='*.pc'
3. Let dir be one of the directories where cppad.pc is located
4. Execute the command export PKG_CONFIG_PATH=dir
5. Execute the command pkg-config --libs --cflags cppad

The output of the last command above will give you all the flags necessary to link cppad.
