Undefined reference to 'inflateInit2_'

Question

I'm using Code Blocks IDE and I want to install Tiled Map Editor for SFML. So, I downloaded the source and imported it to my project. Unfortunately, the build finished with an error due to missing zlib library. I downloaded it and built again. This time I received an error that reads:

undefined reference to `inflateInit2_'|
undefined reference to `inflateEnd'|
undefined reference to `inflateEnd'|

On the Internet I found the advice to join the linker command -lz, but the compiler refuses throwing the error: cannot find -lz. Does anyone know how to fix it?

Answer 1

Use the option -L<path> to tell the linker where to find libz.so.x.y.z.

For your reference: http://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html

Answer 2

you can see where your zlib is installed like this :

/sbin/ldconfig -p| grep libz.so

it should find one or more entries if installed, otherwise it will return blank line
