From bd760c3f5146c75e05ede023f8ef0afd8bce5d74 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 4 Aug 2015 20:00:35 +0200 Subject: [PATCH] toolchain-external: add support for gcc version dependency This commit wires up the gcc version dependency mechanism in the external toolchain backend. To do so, it: * Changes the definition of all pre-defined external toolchain profiles to select the appropriate BR2_TOOLCHAIN_GCC_AT_LEAST_* option. * For custom external toolchains, provides a visible Config.in "choice" to select the gcc version used in the external toolchain. * Adds a new check_gcc_version function, that verifies that the real gcc version found in the external toolchain matches the one declared in the Buildroot configuration. [Thomas: use better sed expression proposed by Yann E. Morin, which works with more cases.] Signed-off-by: Thomas Petazzoni --- toolchain/helpers.mk | 30 ++++++++ toolchain/toolchain-external/Config.in | 70 +++++++++++++++++++ .../toolchain-external/toolchain-external.mk | 2 + 3 files changed, 102 insertions(+) diff --git a/toolchain/helpers.mk b/toolchain/helpers.mk index 895f3f1460..018f3edb92 100644 --- a/toolchain/helpers.mk +++ b/toolchain/helpers.mk @@ -174,6 +174,36 @@ check_kernel_headers_version = \ exit 1; \ fi +# +# Check the specific gcc version actually matches the version in the +# toolchain +# +# $1: path to gcc +# $2: expected gcc version +# +# Some details about the sed expression: +# - 1!d +# - delete if not line 1 +# +# - s/^[^)]+\) ([^[:space:]]+).*/\1/ +# - eat all until the first ')' character followed by a space +# - match as many non-space chars as possible +# - eat all the remaining chars on the line +# - replace by the matched expression +# +# - s/\.[[:digit:]]+$// +# - eat a dot followed by as many digits as possible up to the end +# of line +# - replace with nothing +# +check_gcc_version = \ + expected_version="$(strip $2)" ; \ + real_version=`$(1) --version | sed -r -e '1!d; s/^[^)]+\) ([^[:space:]]+).*/\1/; s/\.[[:digit:]]+$$//;'` ; \ + if [ "$${real_version}" != "$${expected_version}" ] ; then \ + echo "Incorrect selection of gcc version: expected $${expected_version}, got $${real_version}" ; \ + exit 1 ; \ + fi + # # Check the availability of a particular glibc feature.
