From: Frank Hunleth Date: Thu, 10 Mar 2016 00:22:05 +0000 (-0500) Subject: erlang: use erlang's native atomic ops X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3135c6374a8f0b5308bb0d1de90d28879cd528a1;p=buildroot.git erlang: use erlang's native atomic ops Now that we're using Erlang 18, the preferred atomic ops implementation for Erlang is its own built-in implementation, so use it instead of libatomic_ops. BR2_PACKAGE_ERLANG_ARCH_SUPPORTS is added now that BR2_PACKAGE_LIBATOMIC_OPS_ARCH_SUPPORTS can no longer be used for checking whether the package can be built. This fixes autobuilder failures on aarch64 and sparc_v8: http://autobuild.buildroot.net/results/0cd/0cd22eb74fa29e5a85bf897762e16ab3daf33962/ http://autobuild.buildroot.net/results/688278236e6d5bcd63b7d4413303eb115a38f3a7/ http://autobuild.buildroot.net/results/7875a7425bfe1f43d46c9a1db9f96b54f7a99b19/ Signed-off-by: Frank Hunleth Signed-off-by: Thomas Petazzoni --- diff --git a/package/erlang/Config.in b/package/erlang/Config.in index 5fa20288c2..56cee5411b 100644 --- a/package/erlang/Config.in +++ b/package/erlang/Config.in @@ -1,14 +1,20 @@ +config BR2_PACKAGE_ERLANG_ARCH_SUPPORTS + bool + # see HOWTO/INSTALL.md for Erlang's supported platforms + # when using its native atomic ops implementation + default y if BR2_i386 || BR2_x86_64 || BR2_powerpc || \ + BR2_sparc_v9 || BR2_arm || BR2_aarch64 + comment "erlang needs a toolchain w/ dynamic library" depends on BR2_USE_MMU # fork() - depends on BR2_PACKAGE_LIBATOMIC_OPS_ARCH_SUPPORTS + depends on BR2_PACKAGE_ERLANG_ARCH_SUPPORTS depends on BR2_STATIC_LIBS config BR2_PACKAGE_ERLANG bool "erlang" depends on BR2_USE_MMU # fork() depends on !BR2_STATIC_LIBS - depends on BR2_PACKAGE_LIBATOMIC_OPS_ARCH_SUPPORTS - select BR2_PACKAGE_LIBATOMIC_OPS + depends on BR2_PACKAGE_ERLANG_ARCH_SUPPORTS help Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. diff --git a/package/erlang/erlang.mk b/package/erlang/erlang.mk index ff4452f68d..6efffde498 100644 --- a/package/erlang/erlang.mk +++ b/package/erlang/erlang.mk @@ -30,9 +30,6 @@ ERLANG_CONF_ENV += erl_xcomp_sysroot=$(STAGING_DIR) ERLANG_CONF_OPTS = --without-javac -ERLANG_DEPENDENCIES += libatomic_ops -ERLANG_CONF_OPTS += --with-libatomic_ops=$(STAGING_DIR)/usr LIBS=-latomic_ops - # erlang uses openssl for all things crypto.
