Issue

After the new build of libode that uses libccd (see conda-forge/libode-feedstock#22), now the dart's test test_ForceDependentSlip fails, see https://github.com/conda-forge/dartsim-feedstock/pull/61/checks?check_run_id=22760346822 and https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=897543&view=logs&jobId=47084397-e614-5090-05b8-c04ebacb88b9 .

Wow, this was tricky. At least in 0.16.2, cmake with ccd enable pass the following flags:

-DdLIBCCD_BOX_CYL 
-DdLIBCCD_CAP_CYL 
-DdLIBCCD_CONVEX_BOX 
-DdLIBCCD_CONVEX_CAP 
-DdLIBCCD_CONVEX_CONVEX 
-DdLIBCCD_CONVEX_CYL 
-DdLIBCCD_CONVEX_SPHERE
-DdLIBCCD_CYL_CYL

while compiling with autotools:

-DdLIBCCD_CAP_CYL
-DdLIBCCD_CONVEX_BOX
-DdLIBCCD_CONVEX_CAP
-DdLIBCCD_CONVEX_CONVEX
-DdLIBCCD_CONVEX_CYL
-DdLIBCCD_CONVEX_SPHERE
-DdLIBCCD_CYL_CYL     

The CMake build has an additional -DdLIBCCD_BOX_CYL flag that is not there in autotools. If one pass ODE_WITH_LIBCCD_BOX_CYL=OFF to the CMake build, indeed all dart test work fine.

That's a good catch! I also confirmed that this fixes the same issue on archilinux: build log, tested docker

[traversaro]

Ack, thanks! I will align manually cmake and autotools in the conda-forge build, and then open an issue upstream.

[traversaro]

By the way, the fact that box-cylinder check is not enable by the enable-ccd autotools flag is documented: https://bitbucket.org/odedevs/ode/src/bcfb66cd5e18e32e27cfaae3651ead930bbcda13/configure.ac#lines-428 .

[traversaro]

Fixed by conda-forge/libode-feedstock#23 in libode==0.16.2=*_14
, upstream issue reported in https://bitbucket.org/odedevs/ode/issues/87/box-cylinder-ccd-check-disabled-by-default .

@traversaro Can this be closed?

[traversaro]

Yes!
