Installing zlib

Installing zlib from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, libzlib, libzlib-wapi, zlib, zlib-wapi can be installed with conda:

conda install libzlib libzlib-wapi zlib zlib-wapi

or with mamba:

mamba install libzlib libzlib-wapi zlib zlib-wapi

It is possible to list all of the versions of libzlib available on your platform with conda:

conda search libzlib --channel conda-forge

or with mamba:

mamba search libzlib --channel conda-forge

Alternatively, mamba repoquery may provide more information:

# Search all versions available on your platform:
mamba repoquery search libzlib --channel conda-forge

# List packages depending on `libzlib`:
mamba repoquery whoneeds libzlib --channel conda-forge

# List dependencies of `libzlib`:
mamba repoquery depends libzlib --channel conda-forge

About conda-forge

conda-forge is a community-led conda channel of installable packages. In order to provide high-quality builds, the process has been automated into the conda-forge GitHub organization. The conda-forge organization contains one repository for each of the installable packages. Such a repository is known as a feedstock.

A feedstock is made up of a conda recipe (the instructions on what and how to build the package) and the necessary configurations for automatic building using freely available continuous integration services. Thanks to the awesome service provided by Azure, GitHub, CircleCI, AppVeyor, Drone, and TravisCI it is possible to build and upload installable packages to the conda-forge anaconda.org channel for Linux, Windows and OSX respectively.

To manage the continuous integration and simplify feedstock maintenance conda-smithy has been developed. Using the conda-forge.yml within this repository, it is possible to re-render all of this feedstock's supporting files (e.g. the CI configuration files) with conda smithy rerender.

For more information please check the conda-forge documentation.

Terminology

feedstock - the conda recipe (raw material), supporting scripts and CI configuration.

conda-smithy - the tool which helps orchestrate the feedstock. Its primary use is in the construction of the CI .yml files and simplify the management of many feedstocks.

conda-forge - the place where the feedstock and smithy live and work to produce the finished article (built conda distributions)

Updating zlib-feedstock

If you would like to improve the zlib recipe or build a new package version, please fork this repository and submit a PR. Upon submission, your changes will be run on the appropriate platforms to give the reviewer an opportunity to confirm that the changes result in a successful build. Once merged, the recipe will be re-built and uploaded automatically to the conda-forge channel, whereupon the built conda packages will be available for everybody to install and use from the conda-forge channel. Note that all branches in the conda-forge/zlib-feedstock are immediately built and any created packages are uploaded, so PRs should be based on branches in forks and branches in the main repository should only be used to build distinct package versions.

In order to produce a uniquely identifiable distribution:

• If the version of a package is not being increased, please add or increase the build/number.
• If the version of a package is being increased, please remember to return the build/number back to 0.

zlib-feedstock's Issues

tracking issue for pkgconfig challenges with lib

Comment:

• gstreamer-audio conda-forge/gstreamer-feedstock#83
• freetype (had to modify conda-forge/celiagg-feedstock#21)

inflatePrime missing

Solution to issue cannot be found in the documentation.

• I checked the documentation.

Issue

While trying to add my package, which depends on zlib, I found that the conda-packaged zlib version seems to be missing the inflatePrime symbol. I get:

undefined symbol: inflatePrime

Out of interest, I tried to do a find /miniconda3/ -iname '*zlib*so' and nm /miniconda3/lib/python3.10/lib-dynload/zlib.cpython-310-x86_64-linux-gnu.so | grep -i inflate and got the output:

                 U inflate
                 U inflateCopy@ZLIB_1.2.0
                 U inflateEnd
                 U inflateInit2_
                 U inflateSetDictionary
00000000000045ff t set_inflate_zdict

inflatePrime simply seems to be missing, even though it should be there since zlib version 1.2.2.4, which was released in 2005.

libzlib package does not contain file *.a but the test exist

Comment:

libzlib test for osx (the same for linux) involve checking the existence of library *.a, which are not in the source package, which makes the test fails:

test ! -f ${PREFIX}/lib/libz.a

https://github.com/conda-forge/zlib-feedstock/blob/main/recipe/meta.yaml#L47
The contents of lib directory shows that no such files exist:

ls pkgs/libzlib-1.2.13-hfd90126_4/lib/
libz.1.2.13.dylib       libz.1.dylib

MNT: The zlib recipe has some lint :(

This is the friendly conda-forge-admin automated user.

I've ran the conda-smithy linter and found some lint in this feedstock 😢.

Here is what I have got:

• The recipe must have a build/number section.

Thanks!

zlib depends on gcc_linux-64 v10*

Comment:

Because zlib depends on gcc v10*:
"build_number": 4,
"build_string": "h166bdaf_4",
"channel": "conda_channel",
"dist_name": "zlib-1.2.13-h166bdaf_4",
"name": "zlib",
"platform": "linux-64",
"version": "1.2.13",
"dependencies": [
"gcc_linux-64 10.*"
],
this can cause conflicts with components that depend on gcc v11*, if try to collect these packages in the one environment and install the dependencies needed for the tests, such as the compiler.
Is it possible to rebuild zlib with gcc 11*?

Something broken with zlib vs. libzlib files (or run-export)

Currently the output libzlib contains (e.g. on linux):

 "files": [
  "lib/libz.so.1",
  "lib/libz.so.1.2.12"
 ],

whereas zlib contains:

 "files": [
  "include/zconf.h",
  "include/zlib.h",
  "lib/libz.a",
  "lib/libz.so",
  "lib/pkgconfig/zlib.pc"
 ],

On top of that, zlib only run-exports a dependence on libzlib (and not zlib), so stuff like libz.so (and the package config) will not be found, leading i.a. (AFAICT) to stuff like:

CMake Error at /home/conda/feedstock_root/build_artifacts/googleapis-cpp_1660576007096/[...]/lib/cmake/grpc/gRPCTargets.cmake:77 (set_target_properties):
  The link interface of target "gRPC::grpc" contains:

    ZLIB::ZLIB

  but the target was not found.

despite the respective package run-depending on libzlib (based on having zlib as a host-dep for grpc-cpp).

As far as I can tell, we need to either:

• run-export zlib (instead of libzlib) from zlib output
• make zlib a thin wrapper around zlib, so that the contained files are identical

PTAL @conda-forge/zlib
CC @hmaarrfk (since you added conda-forge/grpc-cpp-feedstock#197)

Upgrade to 1.2.10

I'll take a look at doing this.
Hopefully can be my 1st conda-forge patch ;)

Remove static libs linux
