Problem with Pyside2 sha256 mismatch, building from sources on Apple Silicon Monterey

[neurodigitaltechnologies]

I have this problem when trying to build it against Apple Silicon on Monterey:

The main issue is I cannot find where that especific sh256 is in any formula inside homebrew-freecad.
Any way to solve this, please?

brew tap --HEAD Freecad/freecad
brew install Freecad/freecad --HEAD --build-from-source --verbose

i don't have access to M1 machine, so it's difficult for to test issues specific to M1. since there are only bottles for amd64 / x86 processors at the moment. it might be that when you attempt to install freecad it's downloading the dependencies for freecad ie. pyside2 there could be a invalid sha256sum for the pyside2 tarball. i'll investigate this and see what i can find.

[vidmik]

I'm also seeing this issue. FWIW the "Actual" checksum seems to be different on every retry.

Edit: Confirmed, for whatever reason the contents downloaded from https://codereview.qt-project.org/gitweb?p=pyside/pyside-setup.git;a=snapshot;h=c7f4942dda0cf72032e7d8c601b1b32b22c4d8f0;sf=tgz differ for every download, both in size and actual data.

Edit2: The mtime (modification time) field in the tar header seems to be the blame, I'm guessing it will be set to the time when the download happens by the code review (Gerrit?) server.

thats some good detective work there. 👍 i bet if you look at the upstream pyside@2 formula theyll have the correct path to the targz file that uses the same shasum.

all that said, im presently afk for the next few hours but if you want to send a pr with an updated url i can def merge it in. thanks again for the detective work. 🙏

im still banging my head with app bundling issues, ...getting closer though

[ipatch]

did y'all attempt to install pyside2 from this tap again, after i merged the below PR?

I'm new to homebrew and tap so ELI5: anything in particular I need to do to get the latest change? Simply running brew install --only-dependencies freecad --with-packaging-utils still leads to the same checksum mismatch problem. This is on macOS 12.0.1 (Monterey) if that matters..?

[ipatch]

homebrew-core provide the pyside2 package as well. for the moment there are quite a few issues that need to be resolved in order to install freecad from using brew install freecad so probably not what you wanna here, but you could try to install the dependencies individually until i or somewhere can work through the issues.

[vidmik]

Understood. Let me know if there's anything specific you want me to try.

[ipatch]

this is what i'm seeing locally on my machine when running the below command

 brew install freecad/freecad/pyside2 -s --verbose 

output of above command

omitted the rest of the output as it just goes through the cmake, make, make install process but it looks there isn't any issues with the sha256.

also you may want to run a

brew update

and make sure your local clone of this git repo aka homebrew tap has 385 commits in it.

the below commands assume you're using a POSIX based shell ie. bash, or zsh (the default macos)

cd (brew --repository freecad/freecad)   
git rev-list --count HEAD          

385

the master branch on my local clone has 385 commits.

and you'll have to build pyside2 from source as this homebrew tap does not presently provide bottles for "montgomery burns"

---

and installing pyside@2

ie.

brew install pyside@2

will supply the freecad dep of pyside2 but you'll have to configure (cmake) , make, make install from a fresh git clone in the meantime until i or someone else can resolve the issues with the freecad formula.

[vidmik]

FWIW brew install freecad/freecad/pyside2 -s --verbose completes successfully, and I do indeed have the latest/greatest master changes (385 commits).

IIUC the source url in the shiboken2.rb file still needs to be updated to something stable, correct? If so, it's not immediately clear to me why it's not using the same url as [email protected] - after all they both appear to refer to 5.15.2. That said, I should probably back away from this slowly now because I'm clearly in over my head.

[vidmik]

Because I'm notoriously bad at giving up on technical challenges I decided to update the url and checksum fields to the same ones used in [email protected] and that does seem to get me past the checksum issue. 🎉

Next up I'm running into the boost issue (#237).

[neurodigitaltechnologies]

Hi @vidmik and @ipatch
The problem is that although you solve the thing related to shiboken, as you are identifying, then we have the thing with "boost on https://github.com/FreeCAD/homebrew-freecad/issues/237.
I modified all .rb Formulas to switch from local versions of the formulas AKA (./$Formula) for home-core or "vanilla" versions. We must do this change recursively across all dependencies.
For example:

In Freecad.rb, changing "[email protected]" with "boost" will use the untouched and latest version from the core.
This eventually works till we face nglib. It's not compiling due to a miss OCC Lib included in the CmakeList.txt I cannot solve. Anyone else is reaching this point?
Kindest!
Luis.

[ipatch]

this issue should be resolved at this point. please comment or reopen if issues arrises again.
