Hallo.
I am trying to create an Eclipse Plugin in order to "embed" the Oracle ProC* (Oracle Precompiler which transforms embedded sql in a .pc file to c code).
So, for example, the typical build order is the following


  1. Write code in .pc file
  2. Invoke Oracle Precompiler with input the previous file. The output is a .c file
  3. Invoke GCC


So, what i need is somehow instruct my plugin that the first build tool which should be invoked is the precompiler, and then continue with the gcc toolchain.

Is it possible, to "inherit" the GCC toolchain and invoke it after the precompiler tool?

Have you read the Managed Build System Extensibility Document? It is
provided with the CDT SDK. You can then base you toolchain on the GNU
toolchain.

I could imagine that you have to write your own builder that is derived from org.eclipse.cdt.managedbuilder.makegen.gnu.GnuMakefileGenera tor. Define a toolchain that inherits most from the the GCC toolchain, except the builder.

Alternatives:
- Define a "external builder" and use ENV ${build_files} to get a set of changed files (i didn't tried ${build_files}, just a guess)
- Write your own toolchain (for details how to do this see org.eclipse.cdt.managedbuilder.gnu.ui). This way you can use the internal builder (managed build system). That's what I did.

Sorry if this is a dumb question, but can this be done (the bold part)? I have not found any info concerning this matter, Sad And what's more I cannot find the superclass or something relevant

It should be all in the plugin.xml of the plugin you have to write. Again the gcc plugin org.eclipse.cdt.managedbuilder.gnu.ui is a good example:

<tool
  id="your.cpp.gnu.compiler"
  superClass="cdt.managedbuild.tool.gnu.cpp.compiler">
</tool>


Just use the gcc id as superclass.

But I never tried this Wink
In my toolchain I only reference the MBS internal builder:

<builder
  id="mybuilder"
  superClass="org.eclipse.cdt.build.core.internal.builder">
</builder>

Is there any such class like 'org.eclipse.cdt.build.core.toolchain.gnu' ?

Sorry for this dumb message.

I have tried to create a plugin which is here http://pastebin.ca/1617553
It doesn't work as it doesn't recognize the .pc files (i think). If anyone could take a look and suggest anything, i would be grateful!

I have a working effort. It needs improvements but it is a base start.
I have tested it successfully on Eclipse 3.2. Any improvements are welcome

I would like to add a custom preprocessing tool to the standard C/C++ GCC toolchain and I would like to know if you have refined your solution since and also what your META-INF/MANIFEST.MF files look like.

Thanks!
