[SOLVED] IfcPlusPlus compiled on Gentoo - questions and alternatives?

The extended app for windows can be downloaded here: http://www.ifcquery.com/

if Fabian is with us this would be a good GSoC too. Only C++ and Qt is required, no special app or ifc knowledge.

I use it for teach IFC basics (until I find a cross-platform equivalent).

Since you are based in Geneva (like me in Switzerland ), where and who do you teach?

Unfortunately this project use WPF which is not implemented in Mono : https://www.mono-project.com/docs/gui/wpf/.

Since I do not know anything about Mono it is a very value information.

too bad pythonocc seems not yet compatible with occt7.3...

As I understand it, it seems like they want to stick with OCE, too, so I wouldn't hold your breath on this one.

I just noticed that PythonOCC is now compatible with OpenCASCADE (official) 7.4.

The older PythonOCC was intended to be used with OCE 0.18 (OCCT 6.9.x).

However, it seems that the author finally gave in, so after a year, the newer PythonOCC is intended for the official OCCT 7.4; this is good news for FreeCAD and for the IFC ecosystem like IfcOpenShell and IfcPlusPlus.

Now the central library is called PythonOCC-core. Maybe this can also be packaged in Debian?

I'd like to add info about how to compile IfcPlusPlus on Arch Linux:

You probably need http://www.openscenegraph.org/, at least that was the single package missing for me. Everything else was already installed

Code: Select all

pacman -S community/openscenegraph

clone the repo

Code: Select all

git clone https://github.com/ifcquery/ifcplusplus.git

In the repo directory, do

Code: Select all

cmake .
make -j$(nproc --ignore=2)
make install

1) observe the dot after the cmake
2) the make options will use all CPU cores -2. If you do a simple make, it will use just one (for me that's a 6x speedup)

In case calling the binary will throw an error

Code: Select all

> SimpleViewerExample
SimpleViewerExample: error while loading shared libraries: libcarve.so: cannot open shared object file: No such file or directory

Then that's because the path /usr/local/lib (where libcarve.so has been installed) is unknown to the linker.

create e.g. a file 99-local.conf (containing the line /usr/local/lib) in the path /etc/ld.so.conf.d
and call

Code: Select all

> ldconfig -v

and you should be set:
