sdfformat on Ubuntu

[dellaert]

I can't get sdformat to install on Linux with instructions on website. I did:

apt-get -y install libtinyxml2-dev libxml2-utils pkg-config ruby-dev ruby wget
apt-get -y install libignition-math4-dev
cd /usr/src
wget http://osrf-distributions.s3.amazonaws.com/sdformat/releases/sdformat-10.5.0.tar.bz2
tar -xvjf sdformat-10.5.0.tar.bz2
rm -f sdformat-10.5.0.tar.bz2
mkdir build
cd build
cmake ..

But get

I can update the README, but can someone comnment on how they got past this? I hope it does not involve also installing urfdom from source etc...

[varunagrawal]

Use the homebrew instructions in the README. Homebrew supports both Mac and Linux so it should work perfectly.

[dellaert]

So, why do we have the Ubuntu instructions if they do not work?

[varunagrawal]

I believe I used those instructions to initially install SDFormat10 to Ubuntu.

I looked up urdfdom and it looks like doing sudo apt install urdfdom-dev should be sufficient to get that dependency. I would still prefer to kill the source install instructions though.

[dellaert]

Installing homebrew in docker is a drag. Can someone help me source install on Linux? what did you do to make it work?

[dellaert]

somebody amongs you must have done this, right? @gchenfc @yetongumich @nrakoski3 ?

[gchenfc]

I used linuxbrew - tried once install from source and it was a nightmare (lots of dependencies) and I gave up.

IIRC I had issues getting the right version of ignition-math or something, but I was also probably not smart enough at the time.

[varunagrawal]

@dellaert what version of Ubuntu are you using?

[varunagrawal]

@dellaert I made a PR with the updated instructions. I used a docker 18.04 image to test this.
