From mboxrd@z Thu Jan 1 00:00:00 1970 From: Romain Naour Date: Sun, 20 Aug 2017 16:41:54 +0200 Subject: [Buildroot] [PATCH] glibc: needs kernel headers >= 4.5 on mips(64) Message-ID: <20170820144154.15347-1-romain.naour@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Since glibc 2.23 [1]: sysdeps/unix/sysv/linux/mips/configure.ac [...] if test -z "$arch_minimum_kernel"; then if test x$libc_cv_mips_nan2008 = xyes; then arch_minimum_kernel=4.5.0 fi fi This mean that if nan2008 support is requested (i.e BR2_MIPS_NAN_2008 in Buildroot) the minimum kernel headers version is 4.5.0 (not 3.2.0). To simplify the dependancy handling in Buildroot we add this dependency for all mips(64), even if BR2_MIPS_NAN_2008 is not selected.

I tried to use BR2_MIPS_NAN_2008 but it trigger a circular dependency in Kconfig. toolchain/toolchain-buildroot/Config.in | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/toolchain/toolchain-buildroot/Config.in b/toolchain/toolchain-buildroot/Config.in index f47001f..967da1a 100644 --- a/toolchain/toolchain-buildroot/Config.in +++ b/toolchain/toolchain-buildroot/Config.in @@ -43,8 +43,9 @@ config BR2_TOOLCHAIN_BUILDROOT_UCLIBC config BR2_TOOLCHAIN_BUILDROOT_GLIBC bool "glibc" depends on BR2_arm || BR2_armeb || BR2_aarch64 || \ - BR2_aarch64_be || BR2_i386 || BR2_mips || \ - BR2_mipsel || BR2_mips64 || BR2_mips64el|| \ + BR2_aarch64_be || BR2_i386 || \ + ((BR2_mips || BR2_mipsel || BR2_mips64 || BR2_mips64el) && \ + BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_5) || \ BR2_powerpc || BR2_powerpc64 || BR2_powerpc64le || \ BR2_sh || BR2_sparc64 || BR2_x86_64 || \ BR2_microblaze || BR2_nios2 @@ -65,6 +66,11 @@ comment "glibc needs a toolchain w/ dynamic library, kernel headers >= 3.2" depends on BR2_USE_MMU depends on BR2_STATIC_LIBS || !BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_2 +# glibc require kernel headers >= 4.5 if nan2008 support is selected. +comment "glibc on mips(64) needs a toolchain w/ headers >= 4.5" + depends on BR2_mips || BR2_mipsel || BR2_mips64 || BR2_mips64el + depends on !BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_5 + config BR2_TOOLCHAIN_BUILDROOT_MUSL bool "musl" depends on BR2_aarch64 || BR2_arm || BR2_armeb || BR2_i386 || \ -- 2.9.5
