Hi Mikael,
In my workflow I use emacs with rtags for snytax awareness.
With your cmake patch, I could easily generate the cmake files and run cmake
with -DCMAKE_EXPORT_COMPILE_COMMANDS to generate the compiler_commands.json
file used by rtags
to understand how the code fits together, and feed it to rdm. Everything worked
out of the box.
I also use rtags, but with vim.
With these changes it was faster than ever to setup a good emacs-based project
for hotspot development. So I encourage these changes!
I have not tested this, but it must be faster, since now I compile the source
twice, once with gcc and once with clang for rtags.
I have still gotten my morning coffee, this step I have to do anyways of course.
Can cmake do incremental updates to compiler_command.json file, would be
awesome if so? (Erik?)
This is what I need, now I can't do incremental builds if change any flags or
add files.

Thanks for doing this!

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
