Build Settings disabled [message #726572]

I have a C++ project, compiled with MinGW. Its Build Settings are entirely disabled. I've been told that's because I'm (not)using Managed Project but sadly I don't know where could I possibly set that. I need those options enabled because I want to change an output directory ( by default it's in Workspace\[Project name]\[Release/Debug] ).

Any ideas? Cheers, Tom

Open Project Properties->C/C++ Build
Check "Generate Makefiles automatically".

As I said before, all of the options on "Builder Settings" tab are disabled ( grayed-out ) and I cannot access them. I'm particularly interested in changing the "Build directory" option at the very bottom, which is unfortunately grayed-out as well (why?). However, "Generate Makefiles automatically" check box is already checked by default.

I'm using the Eclipse Indigo Release, if that could help in any way.

hmmm, not sure sorry, I thought managed build was the old way.
Did this project already exist? or did you create it from a directory? or import it from the filesystem? Personally for existing code I usually say new C++ makefile project, and then give it an existing directory. If _all_ of the settings in the Builder Settings tab are greyed out, I would suspect your project file is broken or incompatible with the version of eclipse cdt you are using. Just some guesses.

Then you are using the internal builder (see "Builder Settings->Builder type). You cannot change the build directory. If you want to change the "Output directory" you can either
- add a post build step that will copy your application (C/C++ Build->Settings->Build steps)
or
- modify the linker command in C/C++ Build->Settings->Tool Settings: C++ Linker

HI,

I want to do the same thing (reallocate the build directory). Can you tell us what need to be changed in the linker setting ?

regards

Jonathan
