We want to try the Parallel physics Gazebo, which list on the website:

http://gazebosim.org/tutorials?tut=pa...

However, we can not install this version of Gazebo successfully under the instruction in the website, and we find some problems after review the source,which list below:

I download the source with the command: hg clone https://bitbucket.org/osrf/gazebo hg clone https://bitbucket.org/osrf/sdformat cd ${WS}/src/gazebo hg update diagnostics_scpeters cd ${WS}/src/sdformat hg update island_threads
sdformat version: the island_threads version seems to be developed based on version sdformat-3.0.3, and the gazebo seemed to be developed on 6.0, but now the source is 7.0

but the source diagnostics_scpeters Gazebo version require to sdformat-4.1.0, which list in cmake/SearchForStuff.cmake

I try to fix the problems by modified the source code, and make and make install it successfully finally, but I can run it successful.

Who can give me any advice?

As you mentioned in the description, the parallel physics was developed with sdformat-3, you might want to merge sdformat-4 to the island_threads branch, or apply the diff in the island_threads to the newly checked out sdformat-4, similar to gazebo as well

Hi, since many threads were talking about parallel physics and we spent some time bringing it back. Right now it has not been merged yet. But if you checkout sdformat from: https://bitbucket.org/rosebudflyaway/... (using branch island_threads) checkout gazebo from: https://bitbucket.org/rosebudflyaway/... (using branch diagnostics_scpeters)

The conflicts should be resolved. We will either update the tutorial or merge this changes to osrf repo. Let us know if this works.

Hi, I have tried to compile sdformat using island_threads branch, but I get a build error

Missing: Ignition math3 library.

Unfortunately in Ubunut 18.04 i can only find libignition-math2 and libignition-math4, 5 6 in the repositories. Any idea where I cant get math3 from?
