Build the ifm3d from source

[piranda85k]

Hello, I'm struggling to install the ROS 2 driver package, especially with the set-up of ifm3d. I've got the same issues as https://github.com/ifm/ifm3d/issues/357#issue-1315071373. But even when I download manually the zip code of the project, the errors appear. I am working on Ubuntu 20.04. Does anyone have a solution ?

Thank you for your support.

For working with ifm3d-ros package you need to build the tagged version (0.93.0) of ifm3d. Current o3r/main-next branch is work in progress for next major release of ifm3d.

Please use following instruction to build the ifm3d for Ros

$git clone -b v0.93.0 https://github.com/ifm/ifm3d.git
$ cd ifm3d 
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr -DBUILD_MODULE_OPENCV=ON -DBUILD_MODULE_PCICCLIENT=ON -DBUILD_MODULE_IMAGE=ON  ..
$ cmake --build .
$ sudo cmake --build . --target install
``

I've tried this several times with the stable compatible versions (0.93.0, 0.92.0, 0.91.0). And I've got always the same issue :

Cannot generate a safe runtime search path for target ifm3d-image-tests
Cannot generate a safe runtime search path for target ifm3d-opencv-tests
Cannot generate a safe runtime search path for target  ifm3d-pcicclient-tests

Hi @piranda85k, Note that in the latest updates of ifm3d-ros2, we actually removed the dependency to openCV and PCL. So you should be able to build ifm3d from the tagged ifm3d release with the usual cmake instructions:

$git clone -b v0.93.0 https://github.com/ifm/ifm3d.git
$ cd ifm3d 
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr  ..
$ cmake --build .
$ sudo cmake --build . --target install

Since you had issues with previous installations, I would also double check that there is no version conflicts. Check in /usr/lib/cmake: is there leftover files there from other versions? Remove them. Same in /usr/lib, you can cleanup all the libifm3d*.so files. Also remember to remove the CMakeCache.txt from the build folder or build from an empty build folder. After that try the build again. You also can check which ifm3d and make sure it uses the library in /usr/bin.

I've cleaned all my old files using the command below to locate them : sudo find / | grep ifm3d\n And it worked. Thanks for your help.
