valgrind

You need to set this option to run with Valgrind:

  CGAL_DISABLE_ROUNDING_MATH_CHECK

This will configure the build against CGAL so that CGAL does not
interfere with Valgrind. If you use cmake-gui, you should be able to
see this option and just click it.

Is it when I install dolfin? I usually use dorsal, where shall change in
this case?

I don't know where this can be changed in Dorsal. Maybe Harish knows?

Might it be something like adding

-DCGAL_DISABLE_ROUNDING_MATH_CHECK=ON

to the cmake line?

Is it need to be added in dorsal?

murtazo

Yes, but AFAIK there is no nice way to do this in Dorsal at the moment.

Harish: Maybe the cmake build chain should obey the CONFOPTS variable similarly as the autotools build chain does? This way Murtazo could simply add

  CONFOPTS=-DCGAL_DISABLE_ROUNDING_MATH_CHECK=ON

in dolfin.package and DOLFIN would then be configured with this option.

I put it the line your wrote into dolfin.package:

NAME=dolfin
SOURCE=lp:
PACKING=bzr
BUILDCHAIN=cmake
CONFOPTS=-DCGAL_DISABLE_ROUNDING_MATH_CHECK=ON

But, still the problem is there.

murtazo

This feature is not yet supported by Dorsal. I was simply suggesting that it should be added. Anyway, adding ${CONFOPTS} to line 209 in dorsal.sh should probably make it work for you. That is, replace this line

  echo cmake ../ -DCMAKE_INSTALL_PREFIX=${INSTALL_PATH} >>dorsal_build

with this

  echo cmake ../ ${CONFOPTS} -DCMAKE_INSTALL_PREFIX=${INSTALL_PATH} >>dorsal_build

Johannes: It does now!

Great!

Johannes: Yes, it works now!

Thanks!
