macOS homebrew Error: freecad/freecad HEAD-d6a9a94 did not build

[doia]

Yes, there seems to be an error, and I think I suspect where it comes from.

I tried the install myself with

Code: Select all

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

which resulted in an error you described as the process detects python3.10 for the python executable.

I --force removed python3.10 and made sure, only python3.9 is installed and linked:

Code: Select all

$ brew uninstall python@3.10
Error: Refusing to uninstall /opt/homebrew/Cellar/python@3.10/3.10.2
because it is required by certbot, coin3d, llvm, llvm@11, pyside2@5.15.2, pyside@2, shiboken2@5.15.2 and sphinx-doc, which are currently installed.
You can override this and force removal with:
  brew uninstall --ignore-dependencies python@3.10
$ brew uninstall --ignore-dependencies python@3.10
Uninstalling /opt/homebrew/Cellar/python@3.10/3.10.2... (3,145 files, 57.2MB)
$ which python3 && python3 --version
/opt/homebrew/bin/python3
Python 3.9.10
$ ls -al /opt/homebrew/bin/python3
lrwxr-xr-x  1 dirkolbrich  admin  39 23 Mär 10:00 /opt/homebrew/bin/python3 -> ../Cellar/python@3.9/3.9.10/bin/python3

Trying again with brew install freecad/freecad/freecad --build-from-source --HEAD --verbose reinstalls python3.10, the llvm@11 dependency of the freecad formulae does that, but it does not link python3.10. The linked python3 --version stays at Python 3.9.10.

And the shiboken2@5.15.2 dependency itself also depends on llvm (which in turn depends on python3.10). Shiboken builds from source while specifying llvm as it compiler, thus setting python3.10 for its executable. But further down the line specifies the python3.9 libraries to use.

In conclusion: the current homebrew-freecad formulae is broken, as its dependencies and sub-dependencies all have mismatching reliance on different python versions. What a mess.

Meanwhile you can build FreeCAD directly from source. I succeed on an M1 machine with that. Can later try with an Intel machine if you need help.

[FreddyFreddy]

Thanks for testing. In the mean-time I have a fresh copy of Monterey in a new volume to eliminate over-time self-induced problems.
Yes, I have Xcode installed (full).
So far I have only run

Code: Select all

brew install freecad/freecad/freecad

as it seemed to be the simplest thing I could test.
I did notice

Code: Select all

==> Installing dependencies for freecad/freecad/freecad: ... python@3.9, boost-python3, python@3.10  ...

and

Code: Select all

which, after our discussions was unexpected.

Moved app bundle -> Applications. Side note: There is no mention of where the app has been placed. In the cellar folder was a surprise.

Anyways, I fired up FreeCAD and errors displayed

{/quote]
Does your M1 build still work? I note the .19.4 release doesn't support Mac or Linux (too busy preparing .20).
If your build script does work on intel, or even if you haven't tested, would it be possible to share it? I'm getting nowhere fast.

[doia]

OK, sorry for the late response. I took me a while to undust my old Intel machine. Here is a very basic build setup for Mac Intel, which does not uses the SMESH or FEM module and does not build an App bundle to keep it as simple as possible.

Code: Select all

# install xcode-select dev tools, needed by the home-brew python@3.9 bottle
xcode-select --install

# make sure git, cmake and python3 are installed
brew leaves
# the returns lines should contain these packages
cmake
git
python@3.9

# check python path and version
which python3 && python3 --version
# this should show the info
/usr/local/bin/python3
Python 3.9.12

# create a FreeCAD folder and clone the freecad source into a freecad-source folder
mkdir -p freecad && cd freecad
git clone https://github.com/FreeCAD/FreeCAD.git freecad-source

# create a build directory
mkdir -p freecad-build && cd freecad-build

# install the base dependencies as per the wiki
brew tap freecad/freecad
brew install eigen
brew install --only-dependencies freecad

# link packages which where installed keg-only
# brew link icu4c -> this somehow fails, as linking icu4c under Mac Intel is prohibited, Mac M1 is ok, we will set the path later
brew link pyside@2 tbb@2020

# export path to installed dependencies
export PREFIX_PATH="\
  /usr/local/opt/coin3d;\
  /usr/local/opt/hdf5;\
  /usr/local/opt/opencascade@7.5.3;\
  /usr/local/opt/qt@5;\
  /usr/local/opt/vtk@8.2;\
  /usr/local/opt/xerces-c"

# prepare cmake with a minimal setup
cmake \
  -DCMAKE_BUILD_TYPE="Release" \
  -DBUILD_ENABLE_CXX_STD=C++17 \
  -Wno-dev \
  -DPYTHON_EXECUTABLE=/usr/local/bin/python3 \
  -DPYTHON_INCLUDE_DIR=/usr/local/opt/python@3.9/Frameworks/Python.framework/Versions/3.9/include/python3.9 \
  -DPYTHON_LIBRARY=/usr/local/opt/python@3.9/Frameworks/Python.framework/Versions/3.9/lib/libpython3.9.dylib \
  -DBUILD_SMESH=OFF \
  -DBUILD_FEM=OFF \
  -DCMAKE_PREFIX_PATH="$PREFIX_PATH" \
  -DCMAKE_INSTALL_PREFIX="./.." \
  ../freecad-source

# set path to icu4c library
export LIBRARY_PATH="/usr/local/opt/icu4c/lib"

# start the build using the cmake —build command, but pipe it through 'time' to measure build duration
# set the -j number according to your available cpu cores, which you can check with 'sysctl -n hw.logicalcpu'
time sh -c 'cmake --build . -j8'

The build should succeed and you can find the executable under freecad-build/bin/FreeCAD. On start this opens a separate Terminal window and the FC Gui should come up.

Thanks!

I'm working through a post by ipatch https://github.com/FreeCAD/homebrew-fre ... git-master dated a few days ago. Its not working yet. Coin3D, PySide2 errors.

Next I'll go wipe that and try yours. If you fired it up, could I impinge on you to show the output? I think there are some things that might appear wrong, but don't matter?

[doia]

Yeah, just post here for further help.

I just saw the post by @ipatch you mentioned, but [edited] it is very confusing to me. I don‘t understand all of the magic he does yet and could not reproduce the script. Maybe I missed some of the steps.

[FreddyFreddy]

Yeah, just post here for further help.

Cool. Just preparing a new Monterey volume. In the mean-time, is there a reason why the path to icu4c is set after the make cmd? I guess I'm getting picky - want to document this all as precisely as possible when it finally works.

[doia]

No reason at all. AFAIK you could also put it before the cmake command.

On macOS Monterey Intel, the command brew link icu4c does not work, as macOS provides some part of this library. You would need brew link icu4c --force to link the homebrew package. Yet I haven't tried the linking of this package, instead provided the path as described. Not providing the path results in an error during cmake --build .

I just checked on macOS Monterey M1, there icu4c was not linked as well. But somehow there is no error during cmake --build. I do not (yet) know the reason why.

[FreddyFreddy]

Yeah, just post here for further help.

OK, moved to your suggestions, clean Monterey volume.

./makefc_3: line 56: -DCMAKE_BUILD_TYPE=Release: command not found

[doia]

Did you specify the paths with export PREFIX_PATH= ...? Can you post your complete workflow from folder setup, package installs with homebrew and cmake command?

The [export PREFIX_PATH=" \] and [cmake \] commands must be entered/copied as complete block into the terminal prompt.

The error messages [string sub-command STRIP requires two arguments.], [Use -Wno-dev to suppress it.] and [./makefc_3: line 56: -DCMAKE_BUILD_TYPE=Release: command not found] suggest that there was some typo in the cmake command and it is not interpreted as a complete block with all argument, but instead line after line.
