set CXXFLAGS for dpkg-buildpackage

[hurryup]

Could you please explain me how can i set CXXFLAGS from the environment for dpkg-buildpackage.

debian/rules
%:
dh $@
export DEB_BUILD_MAINT_OPTIONS = hardening=+all
DPKG_EXPORT_BUILDFLAGS = 1
include /usr/share/dpkg/buildflags.mk

I try CFLAGS+="-g -O6" dpkg-buildpackage -us -uc, but I see -g -O2 when package builds.

Can't help you much with compiler flags, but in a rules file, the environment stuff must go before the first target. Also the white-space needs to be correctly formatted. Recipes need a single leading tab. Make sure there is a empty/blank line right at the end. Start by trying this instead;

Code: Select all

#!/usr/bin/make -f

export DEB_BUILD_MAINT_OPTIONS = hardening=+all
DPKG_EXPORT_BUILDFLAGS = 1
include /usr/share/dpkg/buildflags.mk

%:
	dh $@

I'm pretty sure you just add to the rules fileL

debian/rules

Code: Select all

export DEB_BUILD_MAINT_OPTIONS = hardening=+all
DPKG_EXPORT_BUILDFLAGS = 1
include /usr/share/dpkg/buildflags.mk

CXXFLAGS=-g -O6  

%:
dh $@

for automake(1) or typical Makefile one can use:

export CXXFLAGS="foo"

(which is used where appropriate not necessarily everywhere)

likely debian should consume the same
