This failed assertion is fairly reproducible when rapidly LMB clicking/dragging slices for a minute or so with slices being fed from slicerecon_server. (Running RECAST3D cab5a9c .)

I am trying to build the develop branch of Recast to work with the develop branch with SliceRecon. This is done because spawning a SliceRecon server crashes Recast if I use the develop branch of SR and the master branch of Recast (this will be a different issue perhaps).

The installation procedure I tried is based on the install script provided in conda/build.sh (I also tried cloning the repo and running cmake but this lead to all sorts of problems solved in the conda build script):

1. In order to use the work done before by using the meta.yaml file provided in conda/meta.yaml we created a conda debug environment:
   conda debug conda/ followed by:
   cd /export/scratch1/schoonho/anaconda3/conda-bld/debug_1571407408363/work && source /export/scratch1/schoonho/anaconda3/conda-bld/debug_1571407408363/work/build_env_setup.sh

2. We prepare glmConfig.cmake:
   mkdir ext/glm/build && cd ext/glm/build
cmake ..
cd ../../../

3. As instructed in the build script, we run:
   declare -a CMAKE_PLATFORM_FLAGS
CMAKE_PLATFORM_FLAGS=(-DCMAKE_TOOLCHAIN_FILE="${RECIPE_DIR}/cross-linux.cmake")

4. We create the build folder and run cmake with the provided flags in build.sh:
   mkdir build && cd build
   Followed by:

cmake ..                                        \
      -DCMAKE_INSTALL_PREFIX=$PREFIX            \
      -DCMAKE_INSTALL_LIBDIR=$PREFIX/lib        \
      -DCMAKE_BUILD_TYPE=Release                \
      ${CMAKE_PLATFORM_FLAGS[@]}                \
      -DOpenGL_GL_PREFERENCE="LEGACY"           \
      -DGLFW_BUILD_EXAMPLES=OFF                 \
      -DGLFW_BUILD_TESTS=OFF                    \
      -DGLFW_BUILD_DOCS=OFF                     \
      -Dglm_DIR="ext/glm/build"

5. We run the make command make -j8.

I get the following errors:

.../ext/tomopackets/tomop/module.cpp:68:52: error: use of 'types' before deduction of 'auto'
         using Init = typename decltype(hana::unpack(
                                        ~~~~~~~~~~~~^
             types, hana::template_<py::detail::initimpl::constructor>))::type;

.../ext/tomopackets/tomop/module.cpp:77:20: error: unable to deduce lambda return type from 'pack'
             return pack;

.../ext/tomopackets/tomop/module.cpp:81:14: error: 'void pack' has incomplete type
         auto pack = hana::unpack(names, indirection);

The GCC version that was used was 9.1.1.

I also tried running:

CXX=... CC=... make -j 8

For GCC version 8.3.0 this gave a different error I did not fully understand:

CMakeFiles/test_server.dir/test/test_server.cpp.o: undefined reference to symbol '_ZSt20__throw_length_errorPKc@@GLIBCXX_3.4'
/bin/ld: /export/scratch1/schoonho/anaconda3/conda-bld/debug_1571407408363/_h_env/lib/libstdc++.so.6: error adding symbols: DSO missing from command line

For GCC version 7.3.0 this gave the same errors as 9.1.1. I am not entirely sure what happened when I ran with gcc 8.3.0.

Also, I see that I have Boost version 1.67.0 if that is relevant since the errors seem Hana related.

Any ideas what I might try?

Hello,

We have tested RECAST3D, managed to install and run successfully. But we have problem with the Center of Rotation.
The visualization is blurred since the center of the rotation need to be adjusted to the one of the captured images.

I would like to ask if this is already implemented in RECAST3D.
If so, how can we adjust it? or is it explained somewhere in the manual?

Thank you.
Best regards,
Amal

I have a 3-dimensional numpy array that stores the 3d graphics (slice) to be displayed internally, which can be seen as the data after reconstruction. How can I transfer this 3d array directly to recast3d for direct display of the graphics without first sending it to slice_recon for reconstruction?

Hello,

I am trying to install Recast3D by following the steps outlined here:

https://cicwi.github.io/RECAST3D/live_software_stack/

When compiling (GCC 9.1.1) I get several errors due to Wfatal-errors and Werror being turned on.

""
RECAST3D/ext/eigen/Eigen/src/Core/CwiseBinaryOp.h:105:49: error: implicitly-declared ‘Eigen::Block<const Eigen::Matrix<float, -1, 3>, 1, 3, false>::Block(const Eigen::Block<const Eigen::Matrix<float, -1, 3>, 1, 3, false>&)’ is deprecated [-Werror=deprecated-copy]
105 | : m_lhs(aLhs), m_rhs(aRhs), m_functor(func)
""
and
""
RECAST3D/include/modules/geometry.hpp:31:29: error: redundant move in return statement [-Werror=redundant-move]
31 | return std::move(packet);
| ~~~~~~~~~^~~~~~~~
compilation terminated due to -Wfatal-errors.
""

when disabling both it compiles fine. In short I got it working but maybe these flags should be removed?

Kind regards,

Richard

The conda package has a number of files in it that it shouldn't, such as assimp/glfw3 development files. In particular the glfw3 cmake files that contain paths from the build environment cause problems.
