Trouble compiling on MacOS 12.3.1

[manroygood]

I am trying to install soqt as part of the installation of the bifurcation software AUTO-07p. The README says to ask for help if you can't get it to build, so here I am.

In the AUTO manual, the instructions are straightforward. Install a few things from home-brew and then make and install soqt

brew install cmake qt@5 coin3d; brew link qt@5 –force
export PATH="/usr/local/opt/qt@5/bin:$PATH"
curl -O -L \
https://github.com/coin3d/soqt/releases/download/SoQt-1.6.0/soqt-1.6.0-src.tar.gz
tar xf soqt-1.6.0-src.tar.gz
cd soqt/build
cmake ..
make
sudo make install

The make step returns many pages of warnings (I'll paste a few to give a flavor and will save them in a file if we need to look at them in more detail.) The program that I use it to build runs, but the window that pops up is mostly just a black rectangle, with a few broken interface elements and containing none of the plots it's supposed to.

Here's a few snippets of the output from make, showing a few typical warnings. A lot are about &&

/Users/goodman/Downloads/soqt/soqt/src/Inventor/Qt/SoQt.cpp:443:18: warning: use of logical '&&' with constant operand [-Wconstant-logical-operand]
  if (SOQT_DEBUG && 0) { // debug
                 ^  ~

Many others complain of deprecated constructors:

/Users/goodman/Downloads/soqt/soqt/src/Inventor/Qt/SoQtGLWidget.cpp:195:43: warning: 'QFlags' is deprecated: Use default constructor instead [-Wdeprecated-declarations]
  PRIVATE(this)->glformat = new QGLFormat(0);
                                          ^
/usr/local/include/QtCore/qflags.h:123:5: note: 'QFlags' has been explicitly marked deprecated here
    QT_DEPRECATED_X("Use default constructor instead") Q_DECL_CONSTEXPR inline QFlags(Zero) noexcept : i(0) {}

Any help would be appreciated.

Did you already tried the prebuilt artifacts or the accompanying source tarballs (coin-latest-src.tar.gz and soqt-latest-src.tar.gz) from the coin CI builds and soqt CI builds prerelease? They are built using Github actions for Catalina, Monterey, and Big Sur. It just might be that we need a new release.

Where do I install these files?

Looking at the output of make one more time, and this particular error stands out as possibly more significant:

ld: warning: dylib (/usr/local/lib/libCoin.4.0.0.dylib) was built for newer macOS version (12.0) than being linked (11.3)
ld: warning: dylib (/usr/local/lib/libX11.dylib) was built for newer macOS version (12.0) than being linked (11.3)

To use the build artifacts you should extract them to a common directory, say /Users/roy/coininstall.
A directory named Coin3D will be created in this common directory.
Then build one of the soqt examples, say tripleview.cpp.
For that to work you need to write a CMakeLists.txt file as follows:

cmake_minimum_required(VERSION 3.0)
project(tripleview)
find_package(Coin REQUIRED)
find_package(SoQt REQUIRED)
add_executable(tripleview tripleview.cpp)
target_link_libraries(tripleview PUBLIC SoQt::SoQt Coin::Coin)

To build your local project run the following commands:

cmake -S tripleview -B tripleview_build -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=Release -D CMAKE_PREFIX_PATH="/Users/roy/coininstall/Coin3D:/opt/local/libexec/qt5"
cmake --build /Users/roy/tripleview_build --target all --config Release

Otherwise you can always try to manually built Coin and SoQt. Extract coin-latest-src.tar.gz and soqt-latest-src.tar.gz to a common directory.
Then run:

cmake -S coin -B coin_build -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/Users/roy/coininstall -D CMAKE_PREFIX_PATH="/Users/roy/coininstall:/opt/local/libexec/qt5" -D COIN_BUILD_DOCUMENTATION=OFF -D COIN_BUILD_TESTS=OFF -D COIN_BUILD_MAC_FRAMEWORK=OFF
cmake --build /Users/roy/coin_build --target install --config Release
cmake -S soqt -B soqt_build -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/Users/roy/coininstall -D CMAKE_PREFIX_PATH="/Users/roy/coininstall:/opt/local/libexec/qt5" -D SOQT_BUILD_DOCUMENTATION=OFF -D SOQT_BUILD_MAC_FRAMEWORK=OFF
cmake --build /Users/roy/soqt_build --target install --config Release
./soqt_build/bin/tripleview

Hope that helps you further
Cheers, Volker

I'm getting closer to what I need, I think. I moved the .dylib files to usr/local/lib and the makefile runs a lot longer before giving any warnings or errors.

Eventually, I encounter a fatal error:

./printToPS.h:7:10: fatal error: 'Inventor/Xt/viewers/SoXtExaminerViewer.h' file not found
#include <Inventor/Xt/viewers/SoXtExaminerViewer.h>

which refers to these lines in a header file

#ifdef USE_SOQT
#include <Inventor/Qt/viewers/SoQtExaminerViewer.h>
#else
#include <Inventor/Xt/viewers/SoXtExaminerViewer.h>
#endif

It appears to me as if USE_SOQT is undefined and it's trying to find an SoXt equivalent. How/where should it be finding one or the other of these headers?
