From 95d534d361b77894de0fe0ee6e5c1f96b60de211 Mon Sep 17 00:00:00 2001 From: Michael 'Mickey' Lauer Date: Thu, 26 Feb 2009 23:44:51 +0100 Subject: minimal.conf: blatantly steal the collective wisdom (and I admit it must have been ton of work, thanks koen et. al.) people put in the angstrom distribution configuration and reorganize the sections a bit for more clarity. Most of this is really distribution-independent, so I'd welcome if angstrom would include one or the other of these sane-*.inc and maintain it there. --- conf/distro/include/sane-toolchain-glibc.inc | 39 ++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 conf/distro/include/sane-toolchain-glibc.inc (limited to 'conf/distro/include/sane-toolchain-glibc.inc') diff --git a/conf/distro/include/sane-toolchain-glibc.inc b/conf/distro/include/sane-toolchain-glibc.inc new file mode 100644 index 0000000000..b14f880328 --- /dev/null +++ b/conf/distro/include/sane-toolchain-glibc.inc @@ -0,0 +1,39 @@ +# glibc: +PREFERRED_PROVIDER_virtual/libiconv ?= "glibc" +PREFERRED_PROVIDER_virtual/libintl ?= "glibc" +PREFERRED_PROVIDER_virtual/libc ?= "glibc" +PREFERRED_PROVIDER_virtual/${TARGET_PREFIX}libc-initial ?= "glibc-initial" +PREFERRED_PROVIDER_linux-libc-headers ?= "linux-libc-headers" + +#Set preferred provider for the C library that is used to build the crosscompiler (NPTL voodoo) +PREFERRED_PROVIDER_virtual/${TARGET_PREFIX}libc-for-gcc = "glibc" +PREFERRED_PROVIDER_virtual/arm-angstrom-linux-gnueabi-libc-for-gcc = "glibc" +PREFERRED_PROVIDER_virtual/armeb-angstrom-linux-gnueabi-libc-for-gcc = "glibc" +PREFERRED_PROVIDER_virtual/arm-angstrom-linux-libc-for-gcc = "glibc" +PREFERRED_PROVIDER_virtual/powerpc-angstrom-linux-libc-for-gcc = "glibc" +PREFERRED_PROVIDER_virtual/mipsel-angstrom-linux-libc-for-gcc = "glibc" +PREFERRED_PROVIDER_virtual/sparc-angstrom-linux-libc-for-gcc = "glibc" + + +TARGET_OS = "linux${@['','-gnueabi'][bb.data.getVar('TARGET_ARCH',d,1) in ['arm', 'armeb'] and bb.data.getVar('MACHINE',d) not in ['collie','h3600', 'h3800', 'simpad', 'htcwallaby']]}" + +#mess with compiler flags to use -Os instead of -O2 +#Please see http://free-electrons.com/doc/embedded_linux_optimizations/img47.html for some more info +# perl has some problems, see http://bugs.openembedded.net/show_bug.cgi?id=1616 +# [23:00] oxo: glibc (any version) on sparc does not like (repeat me) "-Os" + +FULL_OPTIMIZATION = "-fexpensive-optimizations -frename-registers -fomit-frame-pointer -O2" + +FULL_OPTIMIZATION_pn-perl = "-fexpensive-optimizations -fomit-frame-pointer -frename-registers -O1" +FULL_OPTIMIZATION_pn-glibc = "-fexpensive-optimizations -fomit-frame-pointer -O2" +FULL_OPTIMIZATION_sparc = "-fexpensive-optimizations -fomit-frame-pointer -frename-registers -O2" + +BUILD_OPTIMIZATION = "-O2" +BUILD_OPTIMIZATION_pn-perl = "-O1" +BUILD_OPTIMIZATION_pn-glibc = "-O2" +BUILD_OPTIMIZATION_sparc = "-O2" + +TARGET_LINK_HASH_STYLE = "${@['-Wl,--hash-style=gnu',''][bb.data.getVar('TARGET_ARCH',d,1) in ['mips', 'mipsel']]}" + +CXXFLAGS += "-fvisibility-inlines-hidden" + -- cgit v1.2.3
