How to fix undefined reference to deflate/inflate

I am trying to run code that use zlib on Debian by using this command

gcc -o new double.c -lz -lm

But I have these errors : how to fix the errors please?

/usr/bin/ld: cannot find -lz
collect2: error: ld returned 1 exit status
Solution

  • You need to install the library and the associated header files. This can be done using the following command:

    sudo apt-get install zlib1g-dev

    Note that you have indicated you have a file named zlib.h in your project directory. This is wrong. Delete it, and use #include <zlib.h> instead of #include "zlib.h". This will use the correct zlib.h, the one installed by the above command.
