[Bug]: Cannot build wheel v19.24.4

[FedericoCozziVM]

What Operating System(s) are you seeing this problem on?

Linux (x86-64)

dlib version

19.24.4

Python version

3.10.12

Compiler

Cmake 3.29.0

Expected Behavior

It should install dlib at its latest version with pip installing syntax:

pip install --upgrade dlib

Current Behavior

pip install dlib

Steps to Reproduce

pip install --upgrade pip
pip install ---upgrade wheel cmake
pip install dlib

Anything else?

(cmake is installed correctly and it successfully install dlib==19.24.2)

[davisking]

cmake isn't really installed right. Try apt install cmake. For whatever reason the version of cmake that comes from pip is broken on a lot of systems.

[FedericoCozziVM]

@davisking Unfortunately I already tried that :( Running sudo apt install cmake gives me cmake is already the newest version (3.22.1-1ubuntu1.22.04.2)

[arrufat]

Are you sure you're using the system-wide CMake instead of the one installed by pip?

[FedericoCozziVM]

@arrufat you're right, I was using pip's one I guess, as you can see from the error traceback it takes it from virtualenv... however, I tried to uninstall it and the error is the same, this time taking the system-wide cmake (in /.local):

      ERROR: CMake must be installed to build dlib
      
      [end of output]

I checked, and the version installed in venv (via pip) was 3.29.0.1 and the system-wide is 3.25.2. Do you know how to force some cmake version during pip install command?

Also, I tried to re-install dlib==19.24.2 forcing it the build (pip install --no-cache-dir) and it ran correctly

[FedericoCozziVM]

@arrufat that's what I tried, in fact the command in error comes from /home/user/.local/bin/cmake ... but still no success

[arrufat]

I would try the following things

• remove all cmake installations (until which cmake returns nothing)
• build dlib in a new and clean virtualenv (python -m venv venv && source venv/bin/activate && pip install cmake==3.25 && pip install dlib)

FYI, I am using CMake 3.29.1 and it works fine.

[Goktug]

I am experiencing the same issue as well. dlib==19.24.2 is working fine but I am having an issue with the latest release.

P.S. Trying it in dockerized env.

[FedericoCozziVM]

I still haven't solved it in my env, but I must say that it's probably a cmake installation issue as @arrufat and @davisking suggested. In fact, I tried to install everything from scratch in an Ubuntu docker image and version 19.24.4 is build and installed just fine

[escalate007]

I am experiencing the same issue as well. dlib==19.24.2 is working fine but I am having an issue with the latest release.

P.S. Trying it in dockerized env.

I tried again and again about 19.24.4 but failed, then follow your advice, replace it with 19.24.2 .It's working now.

[Yuanyuan-888]

I am using linux system, and now the cmake version is okay (>3.8)

However, I can not "pip install dlib"

It showed the following error " cmd_obj.run()
File "/tmp/pip-build-env-_31gghmv/overlay/lib/python3.9/site-packages/setuptools/_distutils/command/build.py", line 132, in run

ERROR: Failed building wheel for dlib

ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects"

I think the same with this bug --cannot build wheels for dlib.

• I had the same problems installing the face-recognition library and got it working after trying these versions of cmake and dlib:

pip install cmake==3.25.2
pip install dlib==19.24.2

• I'm using a virtual environment with Python 3.9.1 and Windows 11, Also in python global I do not have cmake or dlib installed, only in my virtual environment

I am using linux system:

This method did not work for me, still "ERROR: Failed building wheel for dlib

[davisking]

Try getting cmake from cmake.org and installing it with their official installer. The versions of cmake available in pip are often broken. I would really only use the official cmake.

help me, i have this problem when downloading dlib

[jeltiy]

This worked for me (CentOS 8)

yum install python3-devel
yum groupinstall 'Development Tools'
pip install dlib

[LTPPPP]

but i use win 11

[davisking]

Cmake isn't installed correctly. You should get cmake from cmake.org. That will work. There are lot of other places that repackage it into semi-broken cmake installers. You probably have one of those.

This worked out for me while developing for Python in Docker container. Manually changed the version of the package.

[nmww]

win11

`pip install cmake==3.25.2

pip install dlib==19.24.2`

(CentOS 8)

`yum install python3-devel

yum groupinstall 'Development Tools'

pip install dlib`
