libpng with CgBI support. CgBI is Apple's proprietary extension, to the PNG image file format. This library is an extension to libpng supporting CgBI file format. The usage is basically identical to that of libpng,. Additionally, color_type returned by png_get_IHDR equals 7 if the opened PNG file is in CgBI format. Note that it does not byteswap the pixels.

            How to deal with build dependencies in source RPM?
            Asked 2022-Mar-12 at 17:02

            I don't usually use Fedora or RPMs, so I'm flying blind here. There are lots of similar questions around here, but none that I found are to the exact point where I'm stuck.

            I have the source RPM for an old game program on Fedora ("six" is the game). I want to add a couple of features, but first I want to make sure I know how to compile it so that any future problems are new. I have not made any changes yet at all.

            How to install local package with conda
            Asked 2022-Feb-05 at 04:16

            I have a local python project called jive that I would like to use in an another project. My current method of using jive in other projects is to activate the conda env for the project, then move to my jive directory and use python setup.py install. This works fine, and when I use conda list, I see everything installed in the env including jive, with a note that jive was installed using pip.

            But what I really want is to do this with full conda. When I want to use jive in another project, I want to just put jive in that projects environment.yml.

            So I did the following:

            1. write a simple meta.yaml so I could use conda-build to build jive locally
            2. build jive with conda build .
            3. I looked at the tarball that was produced and it does indeed contain the jive source as expected
            4. In my other project, add jive to the dependencies in environment.yml, and add 'local' to the list of channels.
            5. create a conda env using that environment.yml.

            When I activate the environment and use conda list, it lists all the dependencies including jive, as desired. But when I open python interpreter, I cannot import jive, it says there is no such package. (If use python setup.py install, I can import it.) How can I fix the build/install so that this works?

            Here is the meta.yaml, which lives in the jive project top level directory:

            ANSWER

            Answered 2022-Feb-05 at 04:16

            The immediate error is that the build is generating a Python 3.10 version, but when testing Conda doesn't recognize any constraint on the Python version, and creates a Python 3.9 environment.

            I think the main issue is that python >=3.5 is only a valid constraint when doing noarch builds, which this is not. That is, once a package builds with a given Python version, the version must be constrained to exactly that version (up through minor). So, in this case, the package is built with Python 3.10, but it reports in its metadata that it is compatible with all versions of Python 3.5+, which simply isn't true because Conda Python packages install the modules into Python-version-specific site-packages (e.g., lib/python-3.10/site-packages/jive).

            Typically, Python versions are controlled by either the --python argument given to conda-build or a matrix supplied by the conda_build_config.yaml file (see documentation on "Build variants").

            Try adjusting the meta.yaml to something like

            conda install matplotlib results in huge list on incompatibilities
            Asked 2022-Jan-11 at 22:09

            I have a conda env that I build from a requirements.yml file that I obtained from a classmate so we could work on a project together. I tried installing matplotlib and it resulted in a gigantic list of incompatibilities that I don't think I could even start tackling manually.

            Here are the most important packages I'm using (the ones that have come up in a few other posts I've looked at and what the error looks like):

            • python 3.9.7
            • tensorflow 2.6.0
            • anaconda 4.11
            • numpy 1.21.2

            • Create separate conda environments. keras-tf should be in a separate environment from (base), which you're doing, but you may want to create it from scratch.
            • When creating an environment from scratch, conda works out the correct dependencies, but if installing from a requirements file, specific versions are being forced. If the yml file being used wasn't from conda, there may be version conflicts.
            • The more packages with a specific version, the more likely there is to be an version conflict.
            • See conda: Creating an environment with commands and Anaconda Tensorflow Documentation

            Wrong PHP version used when installing composer with Alpine's apk command

            Huh. This surprised me a bit.

            composer is correctly reporting the PHP version it's using. The problem is that it's not using the "correct" PHP interpreter.

            The issue arises because of how you are installing composer.

            Apparently by doing apk add composer another version of PHP gets installed (you can find it on /usr/bin/php8, this is the one on version 8.0.14).

            Instead of letting apk install composer for you, you can do it manually. There is nothing much to install it in any case, no need to go through the package manager. Particularly since PHP has not been installed via the package manager on your base image.

            I've just removed the line containing composer from the apk add --update command, and added this somewhere below:

            Puppeteer not working NodeJS 17 on Arch Linux
            Asked 2021-Nov-28 at 07:25

            I've started working with Puppeteer and for some reason I cannot get it to work on my box. This error seems to be a common problem (SO1, SO2) but all of the solutions do not solve this error for me. I have tested it with a clean node package (see reproduction) and I have taken the example from the official Puppeteer 'Getting started' webpage.

            How can I resolve this error?

            There's too much for me to put this in a comment, so I will summarize here. Maybe it will help you, or someone else. I should also mention this is for RHEL EC2 instances behind a corporate proxy (not Arch Linux), but I still feel like it may help. I had to do the following to get puppeteer working. This is straight from my docs, but I had to hand-jam the contents because my docs are on an intranet.

            I had to install all of these libraries manually. I also don't know what the Arch Linux equivalents are. Some are duplicates from your question, but I don't think they all are:
            pango libXcomposite libXcursor libXdamage libXext libXi libXtst cups-libs libXScrnSaver libXrandr GConf2 alsa-lib atk gtk3 ipa-gothic-fonts xorg-x11-fonts-100dpi xorg-x11-fonts-75dpi xorg-x11-utils xorg-x11-fonts-cyrillic xorg-x11-fonts-Type1 xorg-x11-fonts-misc liberation-mono-fonts liberation-narrow-fonts liberation-narrow-fonts liberation-sans-fonts liberation-serif-fonts glib2

            If Arch Linux uses SELinux, you may also have to run this:
            setsebool -P unconfirmed_chrome_sandbox_transition 0

            It is also worth adding dumpio: true to your options to debug. Should give you a more detailed output from puppeteer, instead of the generic error. As I mentioned in my comment. I have this option ignoreDefaultArgs: ['--disable-extensions']. I can't tell you why because I don't remember. I think it is related to this issue, but also could be related to my corporate proxy.

            There is none by default, as neither distutils nor setuptools support the field. Also, requires_external keyword arg is not supported as well - it is silently ignored, just as any other unknown keyword arg.

            To add local support for requires_external kwarg, you need to provide your own distribution implementation. Minimal example (requires Python 3.9):
