Absolute paths and project sharing [message #180147]

Hi,

I have created a managed make CDT project successfully in my computer.
I'm using Windows.
But when I copied the project to another computer the following problems
have arisen:

- org.eclipse.cdt.managedbuilder.core.prefs has hardcoded the absolute
paths to MinGW. The other computer has MinGW installed in other path.
Both computers have different drive letter assignments, so they must be
installed on different paths. I have entered this settings also in global
preferences. Why is this setting stored in the project instead of on the
workspace?

- *.launch files used to debug my executable has hardcoded the path to
GDB. It would be interesting to have this setting in global preferences
(even though it could be overriden in the launch file).

What do you think?

Regards
David

Projects are not designed to be copied across machines. You need to Export it to
the file system, copy the exported directory (or archive) to the new machine and
then Import it to your new workspace.

I suggest using an Eclipse variable instead of hardcoding a path. Suggest you
use something like ${env_var:ENV_VAR_NAME}.

Note: Eclipse variables aren't well documented, but you can find a list from
Run->Debug, Environment (tab)-> New (button)-> Edit (dialog) -> Variables (dialog)

Thanks Derek for your quick response.
The env var trick is good.
With JDT you specify once the JVM locations, and this info isn't coded in
the project file. I have the project file under a source control system.
This idea could also be used for CDT.

David,

you could also specify workspace variables, they are evaluated in the
Managed Build System. But this is not fundamentally different from
Environment variables. Just a different place to put the variable, but
certainly outside of the project.

Cheers,

Norbert
