GUDHI
GudhUI will not compile because of alleged missing Qt5 components, despite Qt being installed.
I compiled GUDHI, but the UI part did not compile.
++ GudhUI will not be compiled because Qt5 COMPONENTS Widgets Xml OpenGL are not foundI've installed qt via brew, which I thought would satisfy the requirements, but it did not.
brew install qt
I'm asking for clarification on whether Widgets, Xml, and OpenGL are included in Qt5, and if I can download Qt5 through brew.
Also, I have done the following, but none make the error go away:
brew cask install qt-design-studio
brew cask install qt-creator
Hello, thank you for your report. First, if you don't specifically mean to use the edge-contraction algorithm on skeleton-blocker datastructure, you can probably ignore GudhUI. Did cmake say anything interesting before that? Did cmake find parts of Qt5 but not some components, or did it not find it at all? You can use cmake-gui or ccmake to examine the result. Maybe you just need to tell it where Qt is with Qt5_DIR. You could check if there are files with a name similar to libQt5Widgets.so.5 (maybe .dylib on mac?) in your brew directory, same with xml and opengl. I am not a pro of cmake, the first thing that comes to mind is running cmake with the --trace option, and looking at the parts that talk about Qt...
I reproduced the issue on a OSx virtual machine.
I know it also requires opengl. I did brew install glfw but it doesn't help.
[EDIT]
I found a fix in this really long thread (update the path regarding your configuration):
brew link --force qt5 && sudo ln -s /usr/local/Cellar/qt/5.14.1/mkspecs /usr/local/mkspecs && sudo ln -s /usr/local/Cellar/qt/5.14.1/plugins /usr/local/plugins
Then you need to install QGLviewer
Thanks to both @mglisse and @VincentRouvreau for their replies. First comes my response to mglisee, and then a response to VincentRouvreau.
CMake
I reduced the number of missing Qt5 components to just QGLViewer since my last post by erasing CMakeCache.txt and refreshing $PATH$. I installed QGLViewer according to the Mac OS X instructions in the QGLViewer website.
Did cmake say anything interesting before that?
Previously I got the following output with some CMake warnings, most of which I was able to avoid by implementing this solution from StackOverflow.

Did cmake find parts of Qt5 but not some components, or did it not find it at all? You can use cmake-gui or ccmake to examine the result.
Originally the only message I got regarding Qt5 was the one in my original post (its components were missing). But running cmake again with the commands you recommended I get the following:
- I don't have
cmake-guiinstalled, so I couldn't try it out. - I run
ccmakewith thec(configure) option and get the following output:

Maybe you just need to tell it where Qt is with Qt5_DIR.
How do I do that?
You could check if there are files with a name similar to libQt5Widgets.so.5 (maybe .dylib on mac?) in your brew directory, same with xml and opengl.
find /usr/local/Homebrew/Library/Taps/homebrew -name "libQt5*"

I tried to run cmake again despite the warnings from the QGLViewer install, but CMake says that the Gudhi UI was still not installed. Maybe I need to pass -CMAKE_BUILD_TYPE="Release"? What is the syntax to do that? Is it like this:
cmake -DPython_ADDITIONAL_VERSIONS=3 -CMAKE_BUILD_TYPE="Release" .. ?
cmake -DPython_ADDITIONAL_VERSIONS=3 -CMAKE_BUILD_TYPE=Release .. will fix the CGAL warning (should be better documented on our side - cf. #87 ).
From what I see in your logs, Qt5 is well installed. CMakeLists.txt says find_package(Qt5 COMPONENTS Widgets Xml OpenGL QUIET) and ccmake on your side clearly shows them:
Qt5OpenGL_DIR */usr/local/opt/qt/lib/cmake/Qt5OpenGL
Qt5Widgets_DIR */usr/local/opt/qt/lib/cmake/Qt5Widgets
Qt5Xml_DIR */usr/local/opt/qt/lib/cmake/Qt5Xml
GudhUI is not compiled because of qglviewer. I will try to install it on my VM and will let you know.
I installed libQGLViewer this way:
cd install/libQGLViewer-2.7.2/QGLViewer/
qmake -spec macx-g++ PREFIX=/usr/local
make
sudo make install
CMake did not manage to find QGLViewer that has been installed in /usr/local/lib/QGLViewer.framework/.
You can hard code the path in the CMake command this way:
cmake -DPython_ADDITIONAL_VERSIONS=3 -CMAKE_BUILD_TYPE=Release -DQGLVIEWER_INCLUDE_DIR=/usr/local/lib/QGLViewer.framework/Headers ..
If I understand well, there should be an environment variable QGLVIEWERROOT that should be set by the QGLViewer installer and it is not done.
Thanks again @VincentRouvreau for helping me out with this issue.
Installing QGLviewer
I tried
qmake -spec macx-g++ PREFIX=/usr/local
But it gave me this output and error:
Info: creating stash file /Users/herman/install/libQGLViewer-2.7.2/QGLViewer/.qmake.stash
Project ERROR: failed to parse default search paths from compiler output
According to some online sources[1][2] the "preferred compiler" on mac OS is clang, so I tried something different and did the following.
qmake -spec macx-clang PREFIX=/usr/local # Returns no output.
make # Returns over 700 lines of output, which are attached (makeOutput.txt)
sudo make install # returns over 200 lines of output, which are attached (makeInstallOutput.txt)
Compiling GudhUI
According to the CMake documentation all the options need to be prefixed with -D. (Scroll down to "Create or update a CMake CACHE entry" in the linked documentation.)
cmake -DPython_ADDITIONAL_VERSIONS=3 -DCMAKE_BUILD_TYPE=Release -DQGLVIEWER_INCLUDE_DIR=/usr/local/lib/QGLViewer.framework/Headers ..
The entire output is below.
I don't get the bug you describe, but when I try to run an example in IPython3 I get the following:

Did you stop after cmake? That's just the configuration step (like qmake), then you actually need to build, see the installation instructions.
Compiling GudhUI (a Qt/C++ user interface for gudhi) is different from the Python module (the gudhi python module). It seems you confuse both. What I see from the cmake logs, you can now compile GudhUI, you have all the required dependencies. To fix your python issue while playing the example:
cd /your/gudhi/path/build/src/python # or cd /your/gudhi/path/build/python
make
export PYTHONPATH="/your/gudhi/path/build/src/python:$PYTHONPATH" # or export PYTHONPATH="/your/gudhi/path/build/python:$PYTHONPATH"
python3
>>> import gudhi
# Shall report no error
Output_Gudhi_cmake.txt Output_Gudhi_make.txt
I did confuse Gudhi with its python package. I tried to install the python package since it seemed it would be simple, but I'm also having problems with it so now I'm troubleshooting both installations to see which one works first.
Installing Gudhi
Did you stop after
cmake? That's just the configuration step (like qmake), then you actually need to build, see the installation instructions.
When I run
cd ~/gudhi/
mkdir build
cd build/
cmake -DPython_ADDITIONAL_VERSIONS=3 -DCMAKE_BUILD_TYPE=Release -DQGLVIEWER_INCLUDE_DIR=/usr/local/lib/QGLViewer.framework/Headers -DWITH_GUDHI_EXAMPLE=ON ..
make
I get this output for cmake
and this output for make (returns 2 warnings and 1 error).
Installing Gudhi Python Package Via Miniconda
@VincentRouvreau, I run
conda install -c conda-forge gudhi
and I see the python package installed at /usr/local/Caskroom/miniconda/base/, but in IPython3 when I type gu, it won't autocomplete to gudhi. Compare to when I type nu, it will autocomplete to numpy. If I type in gudhi, it doesn't return an error, but I still can't run the example.

Quite strange... Do you see gudhi when you do:
conda list
You shall see something like
...
gudhi 3.1.1 py36hb3f55d8_0 conda-forge
...
Sorry I've been gone the last few days. I've been distracted with the virus outbreak, and it's supposed to be spring break...
Calling conda list gives me
gudhi 3.1.1 py37he63e17b_1 conda-forge
Same here with virus outbreak, and no school for the children...
Ok so now what do you have in your folder /usr/local/Caskroom/miniconda/pkgs/gudhi-3.1.1-py37he63e17b_1/lib/python3.7/site-packages/gudhi ?
If it does not exist, you can find it by doing:
find /usr/local/Caskroom/miniconda -name gudhi
It shall contain some .py files and some .dylib, if I remember well how it is named on OSx.
Just some very basic checks:
I see the python package installed at
/usr/local/Caskroom/miniconda/base/, but in IPython3
Are you running the ipython3 provided by miniconda?
when I type
gu, it won't autocomplete togudhi
You mean after doing import gudhi, right? And you aren't running ipython3 from a directory that contains a subdirectory named gudhi?
I was able to run an example by adding the miniconda python paths to my preferred instance of python. The work-around was to add the path of the gudhi modules in miniconda to the list of paths of my preferred python instance. I'm wondering if this is the best fix, however. Details below.

which ipython3
returns

But, going off of your suspicion, I did the following:

So I guess the problem has something to do with the paths. By the way, as far as I know, I have
- Python 2.7, which comes with macOS,
- Python 3, which I downloaded, and whose packages I all install using
pip install --user - Python 3, which was installed by Miniconda.
I also had
- Python 3 installed by brew as a prereq for Qt5, but which is now deleted.
So I guess the solution would involve adding the miniconda packages path to the path of my preferred Python instance.
miniconda python paths:
/usr/local/Caskroom/miniconda/base/bin/python

>>> for x in sys.path:

According to this SO answer, the problem could stem from a bad PYTHONPATH.
So I can add the paths after starting IPython, but not before. So the only solution is to add the minicondapaths to my ipython_config.py file. And indeed this works.

But I'm worried why I wasn't able to add the paths to PYTHONPATH. This implies some incompatibility, and I don't want it to come and haunt me later.
when I type
gu, it won't autocomplete togudhiAnd you aren't running ipython3 from a directory that contains a subdirectory named gudhi?
Are you referring to this directory?
/Users/herman/Library/Python/3.7/lib/python/site-packages
The "gudhi" folder there was from when I confused the GUDHI python package with the regular GUDHI. I have since deleted that "gudhi" folder.
You mean after doing
import gudhi, right?
In IPython3, before importing, it will autocomplete names, like for numpy or just about everything else. After adding the miniconda python paths, IPython3 has been able to autocomplete gu to gudhi :+1:
