Ubuntu focal (20.04.2) build failure

[gak]

Hi,

Thanks for this awesome crate. I'm having issues building this in Ubuntu in a Docker image. I'm not well versed in cmake so I'm having problems working out why. The relevant (I think) error is:

#14 108.8   CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
#14 108.8     Could NOT find LibOSRM (missing: LibOSRM_LIBRARY_DIRS LibOSRM_CXXFLAGS
#14 108.8     LibOSRM_LIBRARIES LibOSRM_DEPENDENT_LIBRARIES LibOSRM_INCLUDE_DIR)

Full error at: https://gist.github.com/gak/ee482b96e6358de2d9675b9d54fa5130

I see that there are built .a files, e.g. libosrm.a but the find_package(LibOSRM) call doesn't seem to find them.

I've made a reproducible repository: https://github.com/gak/rs_osrm_test

It's just a matter of having Docker installed and run make, and the error should show up.

If you want to interactively debug it, comment out the RUN cargo build in the Dockerfile, make the build, then run docker run -it rs_osrm_test bash, then run cargo build in the container instance.

Hi, thanks for the detailed report. Im on vacation at the moment but will look into it as soon as I can.

Hi, There seems to be a problem with the installation of osrm-backend. I added a temporary fix in your docker file to download and build/install osrm-backend before building the project and it worked for me. When I'm back I will do a proper fix but this should work for now.

Thanks for this temp fix, it works perfectly. I'll leave the issue open for the proper fix.

Enjoy the vacation!
