The gorgeous and complex natural setting was perfect for testing the abilities and limits of the camera. The main portion of our trip was spent at the Olympic Peninsula in Washington. Now that the camera and the software were ready, there was no better time to test it. My dad had been designing calibrated multi-sensor cameras for as long as I can remember, and since February was working determinately on developing principally new algorithms for reconstructing a 3D model from a set of 4 simultaneously taken photographs. In August of 2017, my family and I went on a trip to the Pacific Northwest, partially for a much needed vacation, but equally as importantly, to test my dad’s new 3D camera. Setting 3D camera on the rock at Cape Alava In the case of such complex system as Linux kernel there still remain several incorrectly resolved links, because different parts of the code may use different header files that share the same names, but there are not many of them, they can be handled manually.Įlphel wiki page Eclipse_CDT_projects_with_bitbake has more details on using Elphel camera projects with Eclipse IDE. Apply the generated exclusion list to the CDT project file “.cproject”.As CDT accepts only “exclude” filters in this context, recursively combine full source list and include_list to generate “exclude_list” pruning all the branches that have nothing to include and replacing them with the full branch reference.Scan all the files from the previously created source list and generate ”include_list” of those that were accessed during the build process.Run bitbake build (“bitbake -c compile -f”).Wait a few seconds to reliably distinguish if each file was accessed after modification.This action prepares the files so the next (first after modification) file access will be recorded as access timestamp. Create a list of the source files (resolving symlinks when needed) and “touch” them, setting modification timestamps.Initialize source/headers directories with bitbake, so it “knows” that everything needs to be rebuilt for the project.To help Eclipse CDT (and users who navigate the source code with it) limit attention to only files and directories that are actually used in the bitbake build process we implemented the following trick (and coded it as used_files.py script): As we did that for the main build command (CDT Builder) the console output is parsed for errors and warnings, results appear as problem markers in “Problems” view and in the source code. Following DRY (“don’t repeat yourself”) principle we removed references to “make” command in the project build and replaced them with bitbake command “bitbake -c compile -f” running in the Eclipse console. Excluded source directories in the Navigator (left) panel are crossed out.Īt the same time all the software components in the distribution are built with the powerful Bitbake build system, and existing ”recipes” and the invoked Makefiles “know” which files to use. We were able to solve this problem (to some extent), but it required a fair amount of manual tweaking and was not universal – developing applications would require different modifications.įigure 1. These files are selected during the build process, and for correct code analysis Eclipse CDT has to reproduce rather complex Linux system of configuration, multi-level macro defines to resolve references in the source code. One of the major challenges of using code analysis tools of Eclipse CDT with the Linux kernel is that there are so many files that define the same names. We tried to use Yocto plugin but were not able to configure it for kernel development, and the kernel drivers development is one of the the largest and probably is the most difficult part of the camera software development, the part were we need Eclipse IDE assistance most. And we use this popular IDE for delivering pre-configured projects to our users to make it easier for them to start efficient modification of the initial camera software and then initiate the new projects. For most of our development (excluding just mechanical and PCB design) we use universal Eclipse IDE: for FPGA development, Linux kernel drivers development, embedded applications and web applications, for editing LaTeX texts. Elphel uses embedded GNU/Linux distribution based on Yocto.
