Error "cannot find -lz"

athlonshi · September 19, 2010, 10:53

Hi,

I encountered compilation error when installing OpenFOAM 1.7.1 on my ubuntu 9.0.4
The error message was shown when entering the src/OpenFOAM folder, which is "cannnot find -lz"
This was also shown when compiling Scotch decomposition library

I am not sure what the z library is. I assumed it is zlib as I noticed that in my ThirdParty-1.7.1, there was not zlib-1.2.3 folder originally when unpacking the downloaded zip file. So, I manually installed z library. This solved other compilation errors when zlib.h was missing. However, the error due to "cannot find -lz" is still there.

Does anyone have suggestion? Thanks very much in advance!

Problem solved after copy libz.so to /usr/local/lib

Greetings Yu Shi,

The package you were missing for libz is this:

Code:

zlib1g-dev

This will install both the library and the headers for it!

Best regards,
Bruno
