Compilation error - missing zlib h

Question

I am trying to compile software on Blue Gene Q using IBM XL compilers and I got this error message    iostreams zlib cpp   line 19 10  1540-0836  S  The  include file  zlib h  is not found  make 3        zlib o  Error 1   I have installed a new version of zlib and updated LD LIBRARY PATH with  HOME zlib include  Am I missing something

You have installed the library in a non-standard location ($HOME/zlib/). That means the compiler will not know where your header files are and you need to tell the compiler that.

You can add a path to the list that the compiler uses to search for header files by using the -I (upper-case i) option.

Also note that the LD_LIBRARY_PATH is for the run-time linker and loader, and is searched for dynamic libraries when attempting to run an application. To add a path for the build-time linker use the -L option.

All-together the command line should look like

$ c++ -I$HOME/zlib/include some_file.cpp -L$HOME/zlib/lib -lz

Maybe you can download zlib h from https   dev w3 org Amaya libpng zlib zlib h  and put it in the directory to solve the problem

In openSUSE 19 2 installing the patterns-hpc-development node package fixed this issue for me

I also had the same problem  Then I installed the zlib  still the problem remained the same  Then I added the following lines in my  bashrc and it worked   You should replace the path with your zlib installation path   I didn t have root privileges   export PATH   PATH  HOME Softwares library Zlib zlib-1 2 11  export LD LIBRARY PATH  LD LIBRARY PATH  HOME Softwares library Zlib zlib-1 2 11 lib  export LIBRARY PATH  LIBRARY PATH  HOME Softwares library Zlib zlib-1 2 11 lib  export C INCLUDE PATH  HOME Softwares library Zlib zlib-1 2 11 include  export CPLUS INCLUDE PATH  HOME Softwares library Zlib zlib-1 2 11 include  export PKG CONFIG PATH  HOME Softwares library Zlib zlib-1 2 11 lib pkgconfig

You are missing zlib h header file  on Linux install it via   sudo apt-get install libz-dev   As a matter of fact  the module presents as zlib1g-dev in the apt repo  so this is the up-to-date call  Feb 2019    sudo apt install zlib1g-dev   On Fedora  sudo dnf install zlib-devel  in older versions  sudo dnf install libz-devel    This will provide the development support files for a library implementing the deflate compression method found in gzip and PKZIP   If you ve already zlib library  make sure you re compiling your code sources with -lz  See  How to fix undefined references to inflate deflate functions
