From 57ce89668864ddad881de84e2780b5db301d12f2 Mon Sep 17 00:00:00 2001 From: sghctoma Date: Wed, 26 Sep 2018 18:13:28 +0200 Subject: Add b_lundef=false Meson option on FreeBSD The Meson option "b_lundef" need to be set to false on FreeBSD, because the symbol "environ" is in crt1.o, which is not linked with shared libraries. With Meson >=0.48.0 it is possible to set this option only for FreeBSD. This patch changes meson.build to do that. --- meson.build | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/meson.build b/meson.build index ff4e5e5f..bd6f1891 100644 --- a/meson.build +++ b/meson.build @@ -111,6 +111,12 @@ wlr_deps += [ math, ] +if host_machine.system().startswith('freebsd') + override_options = ['b_lundef=false'] +else + override_options = [] +endif + symbols_file = 'wlroots.syms' symbols_flag = '-Wl,--version-script,@0@/@1@'.format(meson.current_source_dir(), symbols_file) lib_wlr = library( @@ -122,6 +128,7 @@ lib_wlr = library( install: true, link_args : symbols_flag, link_depends: symbols_file, + override_options: override_options, ) wlroots = declare_dependency( -- cgit v1.2.3 From aacf0c427f7c2ade34c0ba28984c3a61efb6afc7 Mon Sep 17 00:00:00 2001 From: sghctoma Date: Wed, 26 Sep 2018 19:36:48 +0200 Subject: Adjust README to reflect change regarding b_lundef With Meson >=0.48.0 it is no longer necessary to pass the flag "-D b_lundef=false" on FreeBSD. --- README.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/README.md b/README.md index 08844313..11a3b381 100644 --- a/README.md +++ b/README.md @@ -74,8 +74,8 @@ Run these commands: meson build ninja -C build -On FreeBSD, you need to pass an extra flag to prevent a linking error: -`meson build -D b_lundef=false`. +If you use Meson older than 0.48.0 on FreeBSD, you need to pass an extra flag +to prevent a linking error: `meson build -D b_lundef=false`.
