Hello,
Is anyone out there successfully created a custom linker? Please share the knowledge (and maybe the plugin.xml as well...)
I am in the middle of creating a custom toolchain for our C projects. The toolchain contains a compiler, a linker and a builder. The compiler and builder (using the internal builder org.eclipse.cdt.build.core.internal.builder) working fine, however I have issues with the linker.
If I inherit the linker from cdt.managedbuild.tool.gnu.c.linker and only replace the command to execute when linking, C projects using this new toolchain compile and build fine. However I want to get rid of some options of the Gnu C linker as we don`t use them.
And this is where the trouble starts. Because if I don`t inherit from the mentioned linker, building our projects generates errors and exceptions, and nothing is happening.
I even tried to add all the sub-option, sub-optionCategories for my own linker, copied from the Gnu C linker. No difference, I get the following errors during build of the test C project:
This is the error on the test workbench:
Errors occurred during the build.
Errors running builder 'CDT Builder' on project 'Test'.
Internal error building project Test configuration Release
java.lang.NullPointerException
Internal error building project Test configuration Release
java.lang.NullPointerException
And this is the error in the main Eclipse window, where I have the plug-in project:
!ENTRY org.eclipse.core.resources 4 2 2012-11-14 12:08:24.647
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".
