[cmake-developers] Adding a non-make based generator

[Saeed, Khurram]

Hi,
Nucleus ReadyStart<https://www.mentor.com/embedded-software/nucleus/readystart/> is an eclipse<https://www.eclipse.org/ide/> based IDE by Mentor Embedded(tm). It is used for creating and building C/C++ based Nucleus RTOS<https://www.mentor.com/embedded-software/nucleus/> projects for embedded devices.
We have added a new generator in CMake to give the option of generating Nucleus ReadyStart based projects to our customers. This is not a 'make-based' generator as Nucleus ReadyStart projects are built using Eclipse CDT managed build system. In this generator we are generating .project and .cproject files for Nucleus ReadyStart application.

Do you think we can contribute this generator to community?

Thanks and Best Regards,
Khurram Saeed, Senior Technical Lead, Mentor Graphics

does that mean it also works for "normal" Eclipse CDT, or only for ReadyStart
?
If it works for Eclipse in general, I would happily remove the current Eclipse
CDT generator (which I wrote).
Do all tests pass using your generator ?

Hi Neundorf,
This generator can only be used for generating Nucleus ReadyStart IDE projects. It generates Eclipse CDT project files that use ReadyStart specific plugins and configurations.

Khurram

specific plugins and configurations.

I have the impression Brad was not overly excited.
On the other I have the impression that the Eclipse CDT team is also not
overly excited of the cmake server mode (at least 2 years ago when I was on
the mailing list).

Would it be hard to extend your generator so that it can also be used for
"normal" Eclipse CDT projects ? Is it already available somewhere, e.g. github
?

Hi Alex,

I have not made it available anywhere so far. Although my target while writing this generator was only to make it work for ReadyStart projects. However, I think with some effort down the road it might be possible to use it for normal Eclipse CDT projects as well.

We want to make it available to general public but we have been wondering whether or not it would be "acceptable" to have a generator that generates managed Eclipse CDT projects?

Best Regards,
Khurram

well, Brad is the maintainer.
I think in general a "real" Eclipse CDT project generator would be preferred
over the existing one which generates a makefile-based project for Eclipse.

I could try to support you a bit.

Does it support generating the project in the build dir, i.e. outside the
source dir (or in a subdir of the source dir), and does then the Eclipse
version control plugin (svn/git) work ?

while generating in a subdir of the source dir. Eclipse version control
plugin also works (I am using git).

Interesting.
How did you get that working ?

Let's say the directories look like this:

src/CMakeLists.txt
build/CMakeCache.txt
build/.project
build/.cproject

I guess this is what you generate, right ?
How do you get the source tree into this project ?
The Eclipse-generator in cmake uses a "linked resource" to the source dir, but
the version control plugin is not activated for those files.
According to the Subversion-Plugin developers this is because the source files
are then outside the "project directory", i.e. no below the directory where
the .project file is located.

So I'm really interested how you got that working.
Can you send the .project and .cproject files for a simple hello-world project,
built out-of-source ?

In this generator we are generating .project and .cproject files
for Nucleus ReadyStart application.

Are those files driving the actual build?

These days the way to support IDEs tends to be using the
cmake server mode:

https://cmake.org/cmake/help/v3.10/manual/cmake-server.7.html

along with one of the existing generators.

Hi Brad,

Yes those files are driving the actual build. I cannot use one of the existing generators because Nucleus ReadyStart projects are built using Eclipse CDT managed build system.
