[pdal] PDAL and PCL

[Es Kay]

Thanks Andrew!


Indeed, createStage() returns a NULL-pointer.

The output of pdal --debug is:


(PDAL Debug) Loading plugins from directory .
(PDAL Debug) Loading plugins from directory C:/Scratch/Libraries/pdal/lib
   - kernels.delta
   - kernels.diff
   - kernels.ground
   - kernels.hausdorff
   - kernels.info
   - kernels.merge
   - kernels.pipeline
   - kernels.random
   - kernels.sort
   - kernels.split
   - kernels.tindex
   - kernels.translate

and the listed directory contains following lib-files:


libpdal_plugin_filter_greedyprojection.lib
libpdal_plugin_filter_gridprojection.lib
libpdal_plugin_filter_hexbin.lib
libpdal_plugin_filter_icp.lib
libpdal_plugin_filter_movingleastsquares.lib
libpdal_plugin_filter_pclblock.lib
libpdal_plugin_filter_poisson.lib
libpdal_plugin_filter_voxelgrid.lib
libpdal_plugin_kernel_density.lib
libpdal_plugin_kernel_pcl.lib
libpdal_plugin_kernel_smooth.lib
libpdal_plugin_reader_greyhound.lib
libpdal_plugin_reader_nitf.lib
libpdal_plugin_reader_oci.lib
libpdal_plugin_reader_pcd.lib
libpdal_plugin_reader_pgpointcloud.lib
libpdal_plugin_reader_sqlite.lib
libpdal_plugin_writer_nitf.lib
libpdal_plugin_writer_oci.lib
libpdal_plugin_writer_pcd.lib
libpdal_plugin_writer_pgpointcloud.lib
libpdal_plugin_writer_sqlite.lib
pdal_arbiter.lib
pdal_boost.lib
pdal_jsoncpp.lib
pdal_util.lib
pdalcpp.lib


So to me, it seems okay so far, right? Interestingly, pdal --drivers is missing some others as well, e.g. *.oci, *.pgpointcloud, *.poisson etc. However, it is listed when I navigate to the pdal bin folder.

Hi guys,

Stage *writer = factory.createStage("writers.pcd");


I get a bad alloc when setting the input (writer->setInput(reader);)

When I type in pdal --drivers, the pcd writers and readers do not appear, although dll-files exist in the bin-folder (the drivers appear when navigated to bin folder in powershell).

If the drivers aren't shown with pdal --drivers, they can't be found by the plugin manager.  My assumption is that createStage() is returning 0.  You can run pdal --debug to show information about the plugin loading process and verify which directories are being searched for plugins.  You can also set the environment variable PDAL_DRIVER_PATH to override the default locations ( ".", "./lib", "../lib", "./bin", "../bin")
