Cannot Setup ICUBcontrib

[pattacini]

@YANGGANG1971 aked the following in vvv-school/vvv18#62:

Brief description

When trying to set up the ICUBcontrib, the reminder said that I need to change CMAKE_INSTALL_PREFIX entry to the path of your liking, preferably in your home and set up the environment. However, I was unable to do so.

Accompanying material

I cannot change the CMAKE_INSTALL_PREFIX entry and it does not work as follows.

Also, while setting up the new environment, ICUBcontrib_DIR, CMAKE_PREFIX_PATH, YARP_DATA_DIRS cannot be found in the setting panel as follows.

@YANGGANG1971 honestly it's very unclear what your problem is about. Try to better describe the context.

The main problem is that I cannot set up ICUBcontrib correctly followed by the links.
http://wiki.icub.org/wiki/Linux:Installation_from_sources

1. The tutorial said that I must change CMAKE_INSTALL_PREFIX entry. I tried and but failed (cannot save these settings). Or is any special requirement for this CMAKE_INSTALL_PREFIX entry? Or is any causal path (/home/icub/robot-code) OK?
   Note: the following settings cannot be saved and no 'g' option can choose to generate this project.

2. I am not sure whether I need to configure the environment.

Configure your environment

If you installed YARP and/or iCub or ICUBcontrib to non-default directories, you need to set your environment.

Set the ICUBcontrib_DIR env var to point to the installation directory.
Append $ICUBcontrib_DIR/bin to your PATH.
Set the CMAKE_PREFIX_PATH env var to point to the installation directory $ICUBcontrib_DIR.
Modify the variable YARP_DATA_DIRS accordingly, i.e.:

YARP_DATA_DIRS=<YARP_INSTALL_PREFIX>/share/yarp:<ICUB_INSTALL_PREFIX>/share/iCub:<ICUBCONTRIB_INSTALL_PREFIX>/share/ICUBcontrib

While configuring the environment, I cannot find the following variables (ICUBcontrib_DIR, CMAKE_PREFIX_PATH, YARP_DATA_DIRS).

Maybe, because I cannot set up the configuration correctly. I must type sudo command line in the terminal as the prefix each time.
e.g.

$ sudo yarpview ....

1. Since YARP gets found correctly 👍 make sure that:
   1. the path /home/icub/robot-code does exist;
   2. press the key c to let CMake configure the project first;
   3. the option g should bring up soon afterward; press g then.
   4. run make install.
2. You might have installed YARP with root privileges (e.g. sudo make install), hence the need for sudo. You could try to revert the installation and repeat it without sudo.

I made a recording video to show the installation error as follows.

The directory path "/home/icub" did exist.

Hi @YANGGANG1971

I might have missed the point of the video and I'm not sure about what kind of message you meant to convey. Maybe you're not familiar with the use of ccmake, so why don't you try the following instead?

$ export ICUBcontrib_DIR=/home/icub/robot-code/iCubContrib
$ mkdir -p ${ICUBcontrib_DIR}
$ cd /home/icub/robot-code/icub-contrib-common
$ mkdir -p build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=${ICUBcontrib_DIR} ../
$ make install

Great! It works!
