From fe5e9e45bb56bccb6c6ad755b21074ce4df26a02 Mon Sep 17 00:00:00 2001 From: Tiago Gomes Date: Mon, 12 Jan 2015 15:13:53 +0000 Subject: Update GCC to 4.9.2 Update the GCC compiler to the 4.9.2 version. It turns out that a C++ compiler is required to build the latest GCC releases, so build one in stages 1 and 2 as well. The updated list of GCC configuration options that either don't work in a cross compiler or are not needed in a temporary compiler, were based on the latest instructions from Linux From Scratch. The inclusion of /lib64 in the lib path for the stage 1 linker is an attempt to turn things more robust rather than to just symlink in /lib stuff that ends up installed in /lib64 (as it is already being done for libgcc_s.so). Ideally, we should configure every chunk to install to /lib, however GCC seems to not honour the `--with-libdir` configuration flag. With this version of GCC, it looks like a sysroot needs to be given at configure time so that `--with-native-system-header-dir` does what it claims to do. Unfortunately, this has the side effect of making GCC not passing to the linker the linker sysroot flag: `-Wl,--sysroot=$SYSROOT`. The workaround is to modify LDFLAGS to give a sysroot directly to GCC, `--sysroot=$SYSROOT`, which will then be further passed down to the linker. As the newest version of GCC finds more warnings than the previous one, `-Werror` was disabled for the coreutils, GDB and Syslinux projects. Syslinux's Makefile had to be patched, as it is not possible to disable `-Werror` for all targets through the NO_WERROR variable. The hack to handle libgcc_eh being required during eglibc's build was removed, as it doesn't seem to be the case anymore. --- strata/bsp-x86_64-generic.morph | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'strata/bsp-x86_64-generic.morph') diff --git a/strata/bsp-x86_64-generic.morph b/strata/bsp-x86_64-generic.morph index a24a34c5..1181d70e 100644 --- a/strata/bsp-x86_64-generic.morph +++ b/strata/bsp-x86_64-generic.morph @@ -20,7 +20,7 @@ chunks: - name: syslinux morph: strata/bsp-x86_64-generic/syslinux.morph repo: upstream:syslinux - ref: 2f6d21d2a560cb5581694fef42ee9a350d5f302f - unpetrify-ref: baserock/morph + ref: 2aab8555987b547b617cbb887e61083fece01541 + unpetrify-ref: baserock/tiagogomes/update-toolchain build-depends: - nasm -- cgit v1.2.1
