Having trouble building this on Linux - ZLIB cmake files not found.

[philstopford]

Trying to build, I get this error. I don't see anything missing in my package list, so I'm not sure how to resolve this.

CMake Error at /usr/share/cmake/Modules/CMakeFindDependencyMacro.cmake:76 (find_package):
  By not providing "FindZLIBNG.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ZLIBNG", but
  CMake did not find one.

  Could not find a package configuration file provided by "ZLIBNG" with any
  of the following names:

    ZLIBNGConfig.cmake
    zlibng-config.cmake

  Add the installation prefix of "ZLIBNG" to CMAKE_PREFIX_PATH or set
  "ZLIBNG_DIR" to a directory containing one of the above files.  If "ZLIBNG"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  /d/development/Release/install/lib/cmake/minizip/minizip-config.cmake:27 (find_dependency)

I do see zlib-ng-config.cmake under /usr/lib/cmake/zlib-ng

so I wonder if this is what's being sought and not found...

[philstopford]

This worked, combined with a symbolic link,

CMAKE_PREFIX_PATH=/usr/lib/cmake/zlib-ng/ cmake --build Release -j 4 --config Release

Both where needed - without the prefix path, the build system failed to see the symbolic link. Just curious if the build system could figure it out based on the name and also the path.

Hi, are you using the cmake "super build" script? That will compile ZLIB and all of the required dependencies:

[philstopford]

Exactly per the instructions. On one of my other machines that workaround doesn’t work and I’ve no idea why yet

Which version of Linux are you running? Also if you can post the build log I'll take a look.

[philstopford]

I’m traveling for a while so it will take me a bit to get you that. I’m running EndeavourOS

Thanks for the logs; I see the error at the end of the log, but not where it originates. Did you capture both stdout and stderr? I think something like this:

command &> logfile

[philstopford]

for: cmake -S tlRender/etc/SuperBuild -B Release -DCMAKE_INSTALL_PREFIX=$PWD/Release/install -DCMAKE_PREFIX_PATH=$PWD/Release/install -DCMAKE_BUILD_TYPE=Release &> conf.log cmake --build Release -j 4 --config Release &> build.log

Looks like the attachments got lost.

Thanks for the files; it looks like there are network errors trying to clone some of the code repositories:

error: RPC failed; curl 92 HTTP/2 stream 5 was not closed cleanly: CANCEL (err 8)
error: 7515 bytes of body are still expected
fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF
fatal: fetch-pack: invalid index-pack output
Had to git clone more than once: 3 times.
CMake Error at /d/development/Release/nlohmann_json/tmp/nlohmann_json-gitclone.cmake:50 (message):
  Failed to clone repository: 'https://github.com/nlohmann/json.git'

I have also seen that occasionally and am not sure why it happens. Maybe try building again at some point and see if the errors persist.

It is likely an upstream issue, see zlib-ng/minizip-ng#722 and zlib-ng/minizip-ng#886.

I am having the same issue but can't really wrap my head around it. There seems to be some conflict between a system-installed zlib-ng and whatever is being built, but I don't know if that is the whole story.
