Hi,

I'm new to this forum (and CDT plugins) so please forgive me if I have posted to the wrong place.

I am interested in creating a custom toolchain but want to start from the ground up. I have followed the tutorial in the Managed Build System Extensibility Document (6 Tutorial: An Example Tool Integration) and have got the basic toolchain working. I think the tutorial does a good job of guiding you through the process of creating a basic toolchain but it is calling a non-existent command (ccc) and therefore doesn't do anything.

I thought that the natural next step would be to try to get it to do something and so I changed ccc to gcc. However, it isn't quite working yet. Here is my output after trying to build a source file:

**** Build of configuration Test Release for project Test ****

make all
'Building file: ../Test.c'
'Invoking: Compiler'
gcc -o"Test.o" "../Test.c"
'Finished building: ../Test.c'
' '
cc Test.o -o Test
process_begin: CreateProcess(NULL, cc Test.o -o Test, ...) failed.
make (e=2): The system cannot find the file specified.

make: *** [Test] Error 2

I think the problem is that it is trying to invoke the cc compiler when I don't have it installed. The Test.o output file is created successfully and I can run it, so I guess I'm not sure why this next step in the process is happening and how to resolve the error.

Here is my plugin.xml file:
<extension
id="org.eclipse.cdt.example.toolchain"
name="Example Tool"
point="org.eclipse.cdt.managedbuilder.core.buildDefinitions ">
<projectType
id="example.toolchain.executable"

Can anyone help?

Thanks,

Hi Again,

I just came across my old post and thought that I would tie up the loose end.

I did manage to get my toolchain working eventually. The reason that I was getting the above error was to do with my gcc configuration. A reinstall of gcc (MinGW) and a restart of the machine fixed it for me.

Just in case anyone else is struggling with a similar problem - try executing gcc manually from the command line and see if you get this error... if so, then maybe a reinstall of gcc will help.

Alan

Hi there,

I am not sure, if you are still available, still I am trying my luck.

I am also trying to build a custom toolchain to build my project. I also followed the tutorial for the CDT MBS. I have the plugin.xml file exactly same as you except that mine is for Linux i.e. osList="linux".

I tried exactly the same was as you have tried changing ccc to gcc and building a project with a hello.c file. Unfortunately, its not working. I get the following error:

make: ***No rule to make target 'test', needed by 'all'.

Do you have any suggestions?

Hi Alan,

I am REALLY REALLY hoping (with my finger crossed) that you will get message and you can reply to me.

I came across your post about custom toolchain in Eclipse forum. I am also trying to build a custom toolchain to build our toolchain. As you said, I also followed the tutorial for the CDT MBS. I have the plugin.xml file exactly same as you except that mine is for Linux i.e. osList="linux". And, the target platform as follows:

<targetPlatform
archList="all"
binaryParser="org.eclipse.cdt.core.ELF"
id="bluebee.toolchain.targetplatform"
isAbstract="false"
name="Bluebee Target Platform"
osList="linux">
</targetPlatform>

I tried exactly the same was as you have tried changing ccc to gcc and building a project with a simple helloworld.c file. Unfortunately, its not working. I get the following error:

**** Build of configuration Test Release for project test ****

make all
make: *** No rule to make target `test', needed by `all'. Stop.

**** Build Finished ****

Could you please help me what should I do to solve this issue? I am struggling with it already for so long. I would be very grateful if you could point out anything.

Thanks a lot in advance!
Kamana
