From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnout Vandecappelle (Essensium/Mind) Date: Tue, 3 Jul 2012 00:05:46 +0200 Subject: [Buildroot] [PATCH v3 1/5] pkg-infra: add host-xxx-package macro Message-ID: <1341266746-15301-1-git-send-email-arnout@mind.be> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Create host-generic-package, host-autotools-package and host-cmake-package macros. Such a macro is more intuitive to use than the $(call ...,host) construct. Also it speeds things up by having one less $(call ...) evaluation. Also includes documentation update, but not for buildroot.html. This brings the time for 'make -qp' (which is used by bash-completion) down from 1.85s to 1.35s on my laptop. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) --- Note: this patch by itself breaks the build because the .mk files have not been converted to the host-xxx-package scheme. v3: - Rename to host-xxx-package v2: - split infrastructure update and update of .mk files into separate patches. - Simplified documentation (removed some irrelevant or wrong comments). docs/manual/adding-packages-autotargets.txt | 10 ++++------ docs/manual/adding-packages-cmaketargets.txt | 9 ++++----- docs/manual/adding-packages-gentargets.txt | 25 +++++++++++-------------- package/pkg-autotargets.mk | 9 ++------- package/pkg-cmaketargets.mk | 9 ++------- package/pkg-gentargets.mk | 11 +++-------- support/scripts/pkg-stats | 12 ++++++------ 7 files changed, 32 insertions(+), 53 deletions(-) diff --git a/docs/manual/adding-packages-autotargets.txt b/docs/manual/adding-packages-autotargets.txt index 428a182..09a2e7c 100644 --- a/docs/manual/adding-packages-autotargets.txt +++ b/docs/manual/adding-packages-autotargets.txt @@ -23,7 +23,7 @@ package, with an example : 11: LIBFOO_CONF_OPT = --enable-shared 12: LIBFOO_DEPENDENCIES = libglib2 host-pkg-config 13: -14: $(eval $(call AUTOTARGETS)) +14: $(eval $(AUTOTARGETS)) ------------------------ On line 6, we declare the version of the package. @@ -67,11 +67,9 @@ package to be built. ~~~~~~~~~~~~~~~~~~~~~~~ The main macro of the autotools package infrastructure is -+AUTOTARGETS+.
