C/C++ IDE support for HotSpot (original) (raw)

Hi all,

I've finally grown tired of manually setting up a hand crafted Eclipse CDT configuration for the JVM sources and decided to share my progress towards improving the overall situation for JVM developers.

To achieve better IDE support without having to add project generators for all different kinds of past or future IDEs I've decided to try to leverage CMake to do project generation. The idea is to have the JDK build system generate a CMakeLists.txt describing all the include paths and definitions required by an IDE to interpret the sources correctly.

Several modern IDEs natively support CMake but we can also rely on the fact that the CMake build system has the ability to generate projects for a number of different IDEs. For information about which generators CMake supports see https://cmake.org/cmake/help/v3.5/manual/cmake-generators.7.html for your CMake version.

To try this out check out (heh) my branch "JDK-8177329-cmake-branch" in the jdk10/sandbox forest: http://hg.openjdk.java.net/jdk10/sandbox/branches So far I've only made changes in the toplevel and hotspot repositories. I've written a short readme in the repo: http://hg.openjdk.java.net/jdk10/sandbox/raw-file/JDK-8177329-cmake-branch/README-cmake.html

It would be great if people tried this out to see if it works on their setup but I don't expect it to work on Windows without changing the makefile to do path conversion. If we can make this work properly then perhaps we can get rid of the Visual Studio generator and rely on CMake to generate VS projects.

It would also be great if someone from build-dev could give me some hints about how to do the file writing and "vardeps" thing properly.

Thanks /Mikael
