Per-directory project properties

[lpcware]

I use both LPCXpresso/CodeRed 3NXP Edition suite. Changing directory optimisation property seems to have no effect.
Anyone can help me?

Thanks for attaching your example project. It appears that there is something very strange going on within the Eclipse CDT build engine that sits underneath LPCXpresso with regards to using the per-directory properties.

I can offer a couple a workarounds that should allow you to avoid the issue....

First of all, in your example, you are setting per-directory properties on [FONT=Courier New][SIZE=1]Subr[/SIZE][/FONT], which is a subdirectory of the main [FONT=Courier New][SIZE=1]src[/SIZE][/FONT] directory in the project, thus:

src - Subr

If you create a new subdirectory within [FONT=Courier New][SIZE=1]src[/SIZE][/FONT], say [FONT=Courier New][SIZE=1]per_dir_settings[/SIZE][/FONT], and move the[FONT=Courier New][SIZE=1] Subr[/SIZE][/FONT] subdirectory inside this, thus:

src - per_dir_settings - Subr

then the per-directory properties should now get used on the files inside [FONT=Courier New][SIZE=1]Subr[/SIZE][/FONT].

Alternatively, create a new source folder, say [FONT=Courier New][SIZE=1]src_O2[/SIZE][/FONT], at the top level within your project, and place the files that you want compiling at -O2 inside there.

With the attached project you can try to change optimisation level of sub1.c from -O0 to -O2; segment text change from 1504 bytes to 1404 bytes.
You can also look for command line in console window to see correct switch (-O0 or -O2).
If you change optimisation level of  "Subr" folder nothing changes.
That's all.

Information on configuring settings at the per-file and per-directory level can be found at:

This all seems to work here without problem (using LPCXpresso 3.6.1).

What settings are you actuallly trying to change/set? It would probably be helpful if you could export a project as a ZIP file that shows up the problem, and attach it to this thread.
