Eclipse CDT Oxygen: created a makefile project and tried to make a build target, but the create build target option is greyed out, so I can't run make. Everything works on the command line. I've got lots of makefile projects with their own makefiles and they build correctly. Seems to be a problem with Oxygen only - no problem with previous versions of Eclipse CDT.

Normally, I import existing code into a Makefile project.
File --> Import --> C/C++ --> Existing Code as Makefile Project

How did you create yours?

What exactly do you mean by "make a build target"?
Are you using the Build Targets view?
Or Project --> Build Targets --> Create..?
Or ????

Yes, I'm using right clicking on the Project and selecting Build Targets and Create is greyed out. After fiddling about and using the makefile on the command line the option has become available, but I still don't know how to get it working for a new project. Also, now that I've created the make target, it appears in the Project Explorer window and not Build window.
Perhaps I'm using the wrong version of CDT for Oxygen - do you know which is the latest?

Upon further investigation there appears to be a problem with the .project file when creating a Makefile Project. The xml needs the following:
<buildSpec>
<buildCommand>
<name>org.eclipse.cdt.managedbuilder.core.genmakebuilder</name>
<triggers>clean,full,incremental,</triggers>
</buildCommand>
</buildSpec>

and then all is well after the project is closed and then reopened (so that it re-reads the .project file).

The only time I've seen this is when the project doesn't have a C/C+ flavor (i.e., no .cproject file).
I haven't been able to create a Makefile Project without one using the many ways available.
Which is why I asked how you created the project.

Actually, it's the after-post response that is slow.
You should check the forum index in another tab before resending a post.
That will prevent multiple postings.
