I cannot reproduce this. You have the most recent version of rosdep. Have you recently called brew update?

[NikolausDemmel]

It turns out the part of the code constructing above error message is slightly faulty and thus does not contain enough information such as for which formula this failed, and what the output that it is trying to parse is.

Would you be comfortable installing an updated version of rosdep manually to aid debugging? The instructions are as follows:

1. Download rosdep source:

cd ~
git clone https://github.com/ros-infrastructure/rosdep.git
cd rosdep
git checkout osx_installer_debugging

2. Uninstall pip version of rosdep and install development version:

sudo pip uninstall rosdep
cd ~/rosdep
python setup.py develop

3. To later go back to the released version from pip, you can do the following:

cd ~/rosdep
python setup.py develop -u
sudo pip install rosdep

[jmtatsch]

that branch osx_installer_debugging does not exist anymore

[jmtatsch]

ah its merged into master already

rosdep install --from-paths src --ignore-src --rosdistro indigo -y

tango-icon-theme is installed in brew but if i want to reinstall it cannot find the formula.
brew tap yields:
homebrew/science
homebrew/versions
osrf/simulation
ros/deps

[NikolausDemmel]

Can you brew update and brew tap --repair?

the formula should be in ros/deps, see https://github.com/ros/homebrew-deps/blob/master/tango-icon-theme.rb

[jmtatsch]

Thanks, after repairing the tap, i could reinstall icon-theme. Then rosdep more or less worked:

[NikolausDemmel]

@MrTatsch thanks for trying out the current version from source. The branch had indeed been merged before you did tried it. Concerning the remaining messages you got:

executing command [brew install boost --with-python]
Warning: boost-HEAD already installed

Rosdep sees boost as "not installed", since it does not have the right options (--with-python missing). But it does not uninstall the existing install. The attempted brew install boost --with python fails with that warning.

executing command [brew install gcc]
Warning: gcc-4.9.1 already installed, it's just not linked

Similar to above, rosdep notices gcc is not linked, so it sees it as "not installed". Executing brew install gcc fails with that warning.

The above two cases are current limitations of rosdep homebrew, requiring manual intervention. Both cases don't happen on a virgin system, or when choosing the --reinstall option for rosdep (but that might not exactly be what you want either).

I suggest the following manual action to get rid of these errors for future installs:

1. Uninstall boost and install again (brew install boost --with-python; takes a while to compile). I suspect you installed the "HEAD" version a while ago, back when the python libs where still included in the boost formula by default. "HEAD" installs will never get automatic upgrades (via brew upgrade). If you now install boost without --with-python, some ROS packages will fail to compile.
2. Execute brew link gcc. If you get errors, it is likely because of an installed gfortran formula. This is no longer needed and gfortran now comes with gcc, so do brew uninstall -f gfortran and then again brew link gcc.

[jmtatsch]

Your suggestions all worked very well.
Let's hope that reduces errors for future installs ;)

I have a very similar problem. I have a clean Mac OS install 10.9.5. I followed http://wiki.ros.org/indigo/Installation/OSX/Homebrew/Source as well as I could but I get the error:
rosdep install --from-paths src --ignore-src --rosdistro indigo -y
executing command [brew install boost --with-python]
Warning: boost-1.56.0 already installed
ERROR: the following rosdeps failed to install

I tried what you suggested "Uninstall boost and install again (brew install boost --with-python; takes a while to compile). " and everything goes fine :

mbp-de-tiberio:ros_catkin_ws tiberio$ brew uninstall boost

But the error continues.

If I try to go on and do ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release
it results in:

brew switched the boost formula recently.
brew install boost --with-python
does not work anymore. instead use
brew install boost-python

unfortunately rosdep still complains and I don't know how to fix it, but the catkin_ws compiled fine after installing boost-python.

[tiberiusferreira]

Thanks!

[ghost]

but how did you install the other dependencies with rosedep complaining?
i also installed boost-python, but /src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release fails!

[jmtatsch]

how exactly does it fail?

[jmtatsch]

Now the same thing with jade, repairing the taps did not help.

rosdep install --from-paths src --ignore-src --rosdistro jade -y

Please use the fully-qualified name e.g. homebrew/science/pcl to refer the formula.

[wjwwood]

@jmtatsch thanks for digging into the issue, can you open a pull request against ros/rosdistro to change the rule to use the homebrew/science/pcl instead of just pcl?
