[GRASS-dev] compile grass on osgeo4w with debug informations

Hi. It’s a long time since I built GRASS on Windows by myself, so forgive my dummy questions…

I would like to build grass on windows with debug infos, to debug a couple of things (inside the core and a plugin).I suppose I should use the -g flag, but I cannot do it from ./configure CFLAGS=“-g”, because it complains:

configure: warning: CFLAGS=-g: invalid host type
configure: warning: CPPFLAGS=-g: invalid host type
configure: error: can only configure for one host and one target at a time

What’s the best place to declare it? I have little experience with Autotools…

Thanks,
giovanni

I would like to build grass on windows with debug infos, to debug a couple
of things (inside the core and a plugin).I suppose I should use the -g flag,
but I cannot do it from ./configure CFLAGS="-g", because it complains:

configure: warning: CFLAGS=-g: invalid host type
configure: warning: CPPFLAGS=-g: invalid host type
configure: error: can only configure for one host and one target at a time

What's the best place to declare it? I have little experience with

declare it mswindows/osgeo4w/package.sh [1]. Eg.

CFLAGS="-g -Wall" \
            CXXFLAGS="-g -Wall" \
            ./configure \
            ...

I hope it helps, Martin

declare it mswindows/osgeo4w/package.sh [1]. Eg.

CFLAGS=“-g -Wall”
CXXFLAGS=“-g -Wall”
./configure
