By configuring with CFLAGS=-ggdb and --without-snmp I can do the debug I need without optimized out functions or variables. Regards, Stef

To get the include path for the net-snmp library, the binary "net-snmp-config" is called with --cflags and the result is appended to CFLAGS.

Is > there an easy way to get CFLAGS=-ggdb when configuring SANE ? Have you ever looked at "./configure --help" to find out what options the configure script supports? There you'll see: Usage: ./configure [OPTION]... [VAR=VALUE]... To assign environment variables (e.g., CC, CFLAGS...), specify them as VAR=VALUE. See below for descriptions of some of the useful variables. [...] Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBSlibraries to pass to the linker, e.g. -l [...] So, it is sufficient to simply call the configure script as: ./configure CFLAGS=-ggdbg (If CFLAGS is set, the configure script uses its value, otherwise it uses the default of "-g -O2", which is what you want to prevent).

If you don't have the time, I can have a look at it, but I am currently pretty much loaded with other obligations, so I will not be able to get to this until at earliest this weekend and probably not even then...

Hello, in order to debug more efficiently, I have to re-edit Makefiles to remove the two -O2 options in CFLAGS and change the -g to the -ggdb option. Is there an easy way to get CFLAGS=-ggdb when configuring SANE ? Regards, Stef

[sane-devel] Project front end
You have not told us what languages you know how to program. I tend to use either C or Perl for most of my work, but I don't often write GUI programs. Other people like C++, or Python, or Java. If there is a SANE binding, or a C-style calling interface, you can use the language of your choice. The choice of language will help you choose the remaining tools, like editor or compiler. allan On Mon, Jun 13, 2011 at 9:16 PM, Tiago Zaniquelli wrote: > Hello, thank you for the reply. > > But I need support and didn't need theses front ends. > > So i want to begin a project.

[sane-devel] 90% off topic - color / gray test strip
Do they really need to be strips? If not, you might get a color scanning calibration target from someone like kodak. allan On Mon, Jun 13, 2011 at 3:48 PM, Pete Lancashire wrote: > I'm looking for a strip or two strips one that is for color correction > and one for grays.

[sane-devel] 90% off topic - color / gray test strip
I was thinking of having a strip on each side of the scanned documents, one for color and one for gray-scale but I'll admint it is a bit overkill. I've been looking at the different IT8 targets. I'll go with getting a Kodak one. It seems it varies quite a bit. but the price is reasonable. If anyone else is interested two URLs http://www.colorwiki.com/wiki/Test_Images and http://www.colorwiki.com/wiki/Kodak_IT8_%28Q60%29_Targets http://www.computer-darkroom.com/it8cal/it8_page_1.htm http://www.computer-darkroom.com/gamma/gamma_1.htm another source of targets http://www.targets.coloraid.de/ -pete On Tue, Jun 14, 2011 at 6:37 AM, m. allan noah wrote: > Do they really need to be strips?
