external scanner info generator warning [message #122111]

hi!

The first time I create a project for my toolchain [selected in Build
Target of Managed Make], I get the following warning:

"Error launching external scanner info generator (gcc -E -P -v
D:/eclipse_platform/eclipse/workspace/.metadata/.plugins/org .eclipse.cdt.make.core/specs.c) "

Does this mean that by default it searches for the GNU path rather than
the path of the toolchain selected?

What is the solution to suppress this warning?

thanks and regards,
Monali

When a managed project is created, as a part of project initialization,
ManagedMake will run a part of ScannerConfigurationDiscovery feature that
tries to read compiler's internal include paths and symbol definitions
from the gcc 'specs' file.
You can change the default command from Preferences->C/C++->New Make
Projects->Discovery Options. There you can specify a command appropriate
for your toolchain, or if there is not such a command, you can disable
'generate scanner info command'.
Note: this will affect all new make projects both standard and managed.

Thanks,
Vmir

Hi Vmir!

I already follow what you have written but I want the paths discovered for
my toolchain instead of 'gcc'. I have written a managed build plug-in for
my toolchain and I would like the scanner Info generator to search for its
specs file rather than the gcc specs file. Can this be done in the plug-in
instead of manually doing the changes in Preferences?

I did find that the function getESIProviderCommand()has 'gcc' hard-coded
in it.
Is this accessible so that I can pass my compiler to it?

thanks and regards,
Monali

Hi Monali,
There are several ways to do it:
1. You can change org.eclipse.cdt.make.core project's manifest
(plugin.xml). There is an ExternalScannerInfoProvider extension point
there and 'defaultCommand' and 'defaultAttributes' parameters define the
command.

2. You can follow the example of ManagedBuild's function
calculateEntriesDynamically, where you can change values retrieved from
preferences before invoking the provider.

3. You can provide your own extension of ExternalScannerInfoProvider
extension point.

For quickest results I would recommend option 2.

Good luck,
Vmir

hi Vmir!

Thanks a lot for the quick help - I have opted for option 1 currently
and would work on option 3 later.

best regards,
Monali
