Compiling on Mac OS Yosemite 10.10.5

[nyholku]

Hi,

slowly recovering from summer and considering getting back to work on FreeCAD and my Navicube.

I don't know if I've lost my memory completely but I was under the impression that I could use FreeCAD under Mac OS Yosemite 10.10.5

Now, looking at the precompiled binaries for 0.17 they work only in 10.11 or later.

UpgradingMac OS is going to be major hassle so not going to do that in a hurry.

Before I see if I can compile 0.17 on 10.10.5 I thought I'd as first are there any known
road blocks i.e. why is it that the pre compiled 0.17 only work on 10.11 or later.

You remember correctly. I changed it to 10.11 because a lot of homebrew formulas didn't have bottles for 10.10 anymore and it took too long to compile them from source on travis ci. Everything still compiles fine on 10.10, though.

Ok, great, thanks!

Since my previous successful build environment has rotted in the half year I've been away from this project I decided to start over. Hate bit rot!

I completely erased homebrew including all the taps.

I dowloaded the latest source from github.

I specifically did NOT try to install the FreeCAD dependencies before hand as I wanted to try Qt5.

0.17 support Qt5 right?

So the first CMake failed with:

Code: Select all

 Qt4 libraries not found.

So I installed Qt5 (up to this point there is no Qt in this system):

Code: Select all

brew install qt5

==> Caveats
We agreed to the Qt opensource license for you.
If this is unacceptable you should uninstall.

This formula is keg-only, which means it was not symlinked into /usr/local,
because Qt 5 has CMake issues when linked.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/qt/lib
    CPPFLAGS: -I/usr/local/opt/qt/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/qt/lib/pkgconfig

==> Summary
🍺  /usr/local/Cellar/qt/5.9.2: 9,021 files, 282.4MB, built in 112 minutes 52 seconds

Gee what waste of CPU cycles and human time building from source is.
(As noted before the world of C/C++ tool chain is broken beyond repair
and this is not FreeCAD's fault. Nobody's fault, it just is).

Above some patch seemed to fail in some way (did understand that and did not investigate).

Should I do something with those LDFLAGS/CPPFLAGS as instructed and what and where is the proper place to do that?


At this point CMake FreeCAD still fails to find Qt (and it looks like it would prefer Qt4):

Since this topic is about compiling, I moved it from Dev forum to here.

0.17 support Qt5 right?

Yes, but there are issues, I think the main issue is one of the associated libs is not yet feature complet with its earlier qt4 version, also on OSX there were some qt4 bugs so it's not perfect either.

[sgrogan]

0.17 support Qt5 right?

There is a CMake flag BUILD_QT5, on Win at least it's un-checked by default. If you can use CMake-gui it will help working through these issues.
Also QT5 builds for OSX are available: https://github.com/FreeCAD/FreeCAD/rele ... g/0.17_pre they are .dmg's and are available for every commit to master. There have been some auto build issues lately, that may be fixed already, but if the file is less than 200+ MB there is probably a problem and shouldn't be downloaded.

Hi!

At this point CMake FreeCAD still fails to find Qt (and it looks like it would prefer Qt4):

You have to use -DBUILD_QT5=1

You should start in a new build folder since adding this flag won't make it work. The CMake cache is "polluted" with Qt4 stuff.

HTH.

Cheers,
Mateusz

[nyholku]

@sgrogan the pre-built binaries are nice but they don't work with MacOS Yosemite so I can't use them and the final goal, besides learning to use FreeCAD, is to be able to contribute something.

@f3nix,@sgrogan thanks for the -DBUILD_QT5=1 info, I will try that next

[peterl94]

In addition to setting BUILD_QT5, you also have to add the qt5 cmake prefix to the cmake prefix path. It will also save you a bunch of trouble if you use the freecad formula to install the needed libraries. You need to install qt 5.6 instead of the latest 5.9 because pyside2 does not work with qt 5.9 yet. This is basically how it is done on travis:

Code: Select all

brew tap homebrew/science
brew tap freecad/freecad
brew install --only-dependencies freecad
brew install --only-dependencies freecad #Ensure all dependencies are satisfied
cmake -DCMAKE_BUILD_TYPE="Release" \
  -DBUILD_QT5=1 \
  -DCMAKE_PREFIX_PATH="/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake"  \
  -DFREECAD_USE_EXTERNAL_KDL=1  \
  -DBUILD_FEM_NETGEN=1 \
  ../FreeCAD-git

[nyholku]

@peterl94

thanks, that (almost) did it!

I installed Qt 5.6 like this:

Code: Select all

curl -O https://raw.githubusercontent.com/Homebrew/homebrew-core/fdfc724dd532345f5c6cdf47dc43e99654e6a5fd/Formula/qt5.rb
brew install ./qt5.rb

I also had to install eigen which your instructions apparently missed:

Code: Select all

brew install eigen

I then built it using:

Code: Select all

cmake -DBUILD_QT5="1" -DBUILD_ROBOT="0" -DFREECAD_USE_EXTERNAL_PIVY="1" -DBUILD_FEM_NETGEN="1"  -DFREECAD_CREATE_MAC_APP="1" ../FreeCAD-git

Now it builds cleanly and launches without problem!

Great, thank you very much.

Now if I only could locate those nice Onshape like icons that someone had made and could install those...
