Hello
I am currently installing packages manually when missing dependencies are occurring on compile
is there a way to make this easier ? I mean if it is possible to compile ros from code, there must be some alternative to aptitude ?
regards
If you run the following command in the root of your workspace folder, it will search through all the package.xml files in the src directory and automatically install missing package binaries using apt:
rosdep install --from-paths src --ignore-src -r
Make sure rosdep is up to date first:
rosdep update
Any package included as a <depend>, <exec_depend>, <build_depend> etc. in any package.xml will be found by the command, so make sure all packages you need to build or run a package are listed it its package.xml.
No, that's not necessarily needed. I just wanted to draw attention to the fact that what @robustify writes is not a complete answer to your question.
If we're talking about packages that have been released, you could try something like this:
rosinstall_generator <the_package> --rosdistro <your_distro> --deps --tar --exclude RPP > the_package_deps.rosinstall
this will ask rosinstall_generator to generate a list of files/repositories to download (actually: .tar files) which you then merge into your workspace using wstool. Then you can run rosdep, which installs the system dependencies, and then you can run catkin_make.
See also #q346123 for a recent Q&A about this procedure.
I am talking about raspbery pi 4 and the fact that I had to compile ROS from the appropriate tutorial
I'll try to use rosdep, but I am pretty sure, I'll end up doing this on my RPI3 in the end :-(
-bash: rosinstall_generator: command not found
but 'rodep update' and 'rosdep install --from-paths src --ignore-src -r' installed some packages
then I could go further installing hector slam...it installed opncv deps , but I keep having unmet dependencies, so I install them manualy
ok but I have an error about some package being not homogenous and such, I checked the logs and there are some compilation errors, I decided to stop tinkering with an unfinished ros package, I'll try on a RPI3 ready to go image
