For the recipes built with klcc-cross it is necessary to pass --sysroot otherwise we default to the one encoded in gcc-cross which actually is the 'first one' built. The issue was revealed when building for armv4 after having built for armv5te: the produced binaries did contain Illegal Instruction (bx lr).
Use ${TOOLCHAIN_OPTIONS} variable to specify --sysroot=${STAGING_DIR_TARGET} Signed-off-by: Andrea Adami <andrea.ad...@gmail.com> --- meta-initramfs/classes/klibc.bbclass | 4 ++-- .../klibc/klibc-2.0.4/klcc-consider-sysroot.patch | 14 ++++++++++++++ meta-initramfs/recipes-devtools/klibc/klibc.inc | 1 + 3 files changed, 17 insertions(+), 2 deletions(-) create mode 100644 meta-initramfs/recipes-devtools/klibc/klibc-2.0.4/klcc-consider-sysroot.patch diff --git a/meta-initramfs/classes/klibc.bbclass b/meta-initramfs/classes/klibc.bbclass index ca741cd..f864104 100644 --- a/meta-initramfs/classes/klibc.bbclass +++ b/meta-initramfs/classes/klibc.bbclass @@ -4,8 +4,8 @@ DEPENDS =+ "klcc-cross" # Default for klcc is to build static binaries. # Set CC = "${TARGET_PREFIX}klcc -shared" to build the dynamic version. -export CC = "${TARGET_PREFIX}klcc" -export CC_armv4_linux-gnueabi = "${TARGET_PREFIX}klcc -march=armv4 -mthumb-interwork" +export CC = "${TARGET_PREFIX}klcc ${TOOLCHAIN_OPTIONS}" +export CC_armv4_linux-gnueabi = "${TARGET_PREFIX}klcc ${TOOLCHAIN_OPTIONS} -march=armv4 -mthumb-interwork" export CPP = "${CC} -E" diff --git a/meta-initramfs/recipes-devtools/klibc/klibc-2.0.4/klcc-consider-sysroot.patch b/meta-initramfs/recipes-devtools/klibc/klibc-2.0.4/klcc-consider-sysroot.patch new file mode 100644 index 0000000..9bc4835 --- /dev/null +++ b/meta-initramfs/recipes-devtools/klibc/klibc-2.0.4/klcc-consider-sysroot.patch @@ -0,0 +1,14 @@ +diff --git a/klcc/klcc.in b/klcc/klcc.in +index 43d0984..61e9385 100644 +--- a/klcc/klcc.in ++++ b/klcc/klcc.in +@@ -204,6 +204,9 @@ while ( defined($a = shift(@ARGV)) ) { + # Libraries + push(@libs, $a); + push(@libs, shift(@ARGV)) if ( $2 eq '' ); ++ } elsif ( $a =~ /^--([sysroot=])(.*)$/ ) { ++ # Override gcc encoded sysroot ++ push(@ccopt, $a); + } else { + die "$0: unknown option: $a\n"; + } diff --git a/meta-initramfs/recipes-devtools/klibc/klibc.inc b/meta-initramfs/recipes-devtools/klibc/klibc.inc index 0209b20..f3e9972 100644 --- a/meta-initramfs/recipes-devtools/klibc/klibc.inc +++ b/meta-initramfs/recipes-devtools/klibc/klibc.inc @@ -16,6 +16,7 @@ SRC_URI_append_linux-uclibceabi = " file://klibc-config-eabi.patch \ " SRC_URI += "file://klibc-linux-libc-dev.patch \ file://staging.patch \ + file://klcc-consider-sysroot.patch \ " S = "${WORKDIR}/git" -- 1.9.1 -- _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-devel
