Re: [cdt-dev] C project settings in Eclipse. Finding which ones I used, what they are, editing, etc.
|
Did you check that your project used external builder instead of
internal one? If not, go to Toolchain editor and do it.

documentation would help out guys like me.
I wear a variety of hats at work, one of which is banging out some
embedded C code from time to time. I probably start a new C project
once a year.
I've been using eclipse for 3 years. I love it. Its a great work.
I've watched the CDT plugin mature and grow and its excellent. I am so
thankful to be able to use Eclipse for all my projects.
But I have a problem. I have a very hard time getting a new project set
up correctly. I always seem to have a problem selecting the right C
project options and getting that first build to work properly. I know
its silly. I know it should be simple, but somehow it isn't for me.
Let me share my latest situation with you.
I have an embedded C project that is all set up and working very well in
Eclipse. I set it up 2 years ago. It uses a makefile that I hand
wrote. It compiles and links and builds just like I want it to. Bliss.
Last week I needed to start a new project. I wanted it to be set up the
same as my existing project, so I cloned it by duplicating the project
directory in the workspace outside of Eclipse (ie with Dolphin in F10)
and then creating a new project in Eclipse and importing the files from
the directory.
All this worked fine except that it doesn't build properly, it has link
errors. When I investigate further, it looks like it might not be using
the makefile and I suspect that I have selected the wrong C project
settings when I set up the project. The reason I suspect this is that
when I look at the project properties, I see different options for
building and such in the first project than in the cloned project.
The key word in that sentence is "suspect". I'll get to that in a bit.
What is actually wrong with my project is irrelevant. I'll figure it
out shortly. The real issue is that I seem to get into this situation
every time I start a new project.
Lets start from the top.
When I create a new C project, I use File->New. That allows me to
select the "C Project" entry. I do.
Then I am presented with the Project Type. Executable, Shared Library,
Static Library and Makefile project. Its obvious, that I want a
Makefile project, right ? I'm pretty sure I selected the Empty Project
under it.
In the toolchain box I see "Other Toolchain" and "Linux GCC". I am
using arm-elf-gcc as my toolchain. I am pretty sure I selected
"Other".
I complete the creation of my project.
However, when I go into my clone project, Under Properties, Build
Variables in the Configuration box it is showing Linux GCC.
Furthermore, I am supposed to be able to change the configuration of the
project if I use "Manage Configurations". I try this, but I can't seem
to get a project that allows me to use an "Other toolchain" and nor can
I get the project builder properties to look like they do in the first
project.
At this point I'm stuck. I obviously haven't set up my project
correctly. I want the build options in Project->Properties to look like
they do in project #1. I don't really know what I selected when I did
set this project up. Nor the one from 2 years ago. I can't seem to
edit what I do have set up. And I don't really know what I would call
what I have set up. I'm frustrated and confused.
Furthermore, I know that the build options in my first project are
different than the cloned project, but I only figured that out by making
when I noticed that one screen had options that the other didn't. For
the first 30 minutes of troubleshooting this, I missed that point.
Sure, its pretty obvious to someone that works with Eclipse every day,
but its probably been a year since I last looked at project properties
in Eclipse and there doesn't seem to be a way to open two project
properties dialogs simultaneously. I finally resorted to getting a
screen shot of each window and placing them side by side.
I've consulted the Help manual throughout this process. I'm not sure it
handles my situation. I understand that developers are busy people and
that its difficult and time consuming to develop documentation that
handles every situation.
I'm not sure what should become of my post. I just wanted to
communicate that some of us find the project creation process to be a
bit complicated. I know that for everyday Eclipse users, this is
trivial. But for someone that does this once or twice a year, its a
different story.
My solution to this problem will be to create another clone project
using slightly different selections until I find the combination that
gives me the same setup as project #1.
Sorry this is so long. I wanted to give the full context so that reader
might understand the whole situation.
Thanks for listening.
