[Solved] Zlib not found when compiling Kodi

[thegrind]

I wanted to upgrade to Kodi 22 so I tried to emerge from the Gentoo repo but it failed saying Zlib not found even though it is installed and it is the latest version. I then tried the kodi-overlay for Gentoo on Github and it gave me the same error. Finally, I just did a git pull from xbmc and did cmake and got the same Zlib error. Does anyone know how to fix this?I looked at the logs and it is looking in the /usr/lib64 and /usr/include where one has the so file and the other has the .h file.

When the ebuild failed, Portage should have directed you to post certain information. We stand a better chance of helping you if you post the information that it told you to share. You may need to use a pastebin for the larger logs.

Here is the log from when I tried to compile kodi.

Okay, I added this to the compile Kodi from git cmake line -DZLIB_LIBRARY=/usr/lib64/libz.so and it didn't give me the Zib error.

The problem is that I don't know how to fix this when I do an emerge. Export?

[Hu]

That pastebin link does not appear to be the build.log, nor to contain any of the standard Portage troubleshooting output. It looks like one part of a manual build, outside of Portage.

The ebuild should produce a working program without you needing to export anything. If it does not, then either something is wrong with your system or there is a bug in the ebuild. In either case, we can try to help you isolate the problem. To start, please provide the standard Portage troubleshooting output. Also, show the output of namei -l /{usr/,}lib{,64}.

[thegrind]

Here is the build log. I tried exporting the Clfag and adding it to the emerge command neither worked.

I had the same problem
In /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake it go to line 603 in this condition

Code: Select all

if(NOT VERSION_OK)

So maybe gentoo zlib is too old.

[Hu]

Gentoo packages, and OP has, zlib 1.3.1, which is the newest available according to https://zlib.net/[b][/b]. According to the build log, it failed to find the associated library.

OP appears to be on an aarch64 system. This may or may not be related.

[Ridrok]

Yes I checked, but can the problem be related to this newest commit
https://github.com/madler/zlib/commit/d ... 8cf3646638
Maybe having it may also fix kodi

The commit message for that commit is Repair MinGW cmake build. The body of the commit is solely for the benefit of Windows users. OP is using Linux on aarch64, which is not Windows.

I met this issue as well (x86-64)

So I run this:

Code: Select all

# USE=static-libs emerge -av1 sys-libs/zlib

These are the packages that would be merged, in order:

Calculating dependencies... done!
Dependency resolution took 2.84 s (backtrack: 0/20).

[ebuild   R    ] sys-libs/zlib-1.3.1-r1:0/1::gentoo  USE="static-libs* -minizip -verify-sig" ABI_X86="(64) -32 (-x32)" 0 KiB

and then kodi-9999 went to compile phase without the cmake failure.

Will add the use flag to zlib therefore through portage. I advise to request such flag in kodi-9999 dependencies.

[Hu]

Static libraries are almost never the right answer. This may suffice as a workaround, but the build should be fixed to work with dynamic libraries.

[thegrind]

It turned out to be an easy fix. I just went to the /var/db/repo and then went to the repo I am using which in my case is kodi-overlay. I then just went to the kodi-9999 ebuild file and just searched for cmake and where it lists the flags I just added -DZLIB_LIBRARY=/usr/lib64/libz.so to the list and kodi merged without issue.

I didn't see this problem with the kodi-pvr-iptvsimple emerge as this didn't have any issues.

Kodi 22 is really nice. Well worth the effort.

It's a shame that none of the people who hit this filed a bug (someone else did on IRC too). Oh well.

Anyway, the real issue was introduced by https://github.com/xbmc/xbmc/pull/26797 and is fixed by https://github.com/xbmc/xbmc/pull/26886[b][/b]. It only affected the live ebuild.
