From ea532f0e725bd68e7784189c9b7f6f7bf7f9d901 Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Sat, 10 Apr 2010 02:41:39 +0100 Subject: scons: Make LLVM a black-white dependency. Now that draw depends on llvm it is very difficult to correctly handle broken llvm installations. Either the user requests LLVM and it needs to supply a working installation. Or it doesn't, and it gets no LLVM accelerate pipe drivers. --- common.py | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'common.py') diff --git a/common.py b/common.py index 97389ed5001..4b6960c66c8 100644 --- a/common.py +++ b/common.py @@ -3,6 +3,7 @@ import os import os.path +import subprocess import sys import platform as _platform @@ -33,6 +34,11 @@ else: default_machine = _platform.machine() default_machine = _machine_map.get(default_machine, 'generic') +if 'LLVM' in os.environ or subprocess.call(['llvm-config', '--version'], stdout=subprocess.PIPE) == 0: + default_llvm = 'yes' +else: + default_llvm = 'no' + if default_platform in ('linux', 'freebsd'): default_dri = 'yes' elif default_platform in ('winddk', 'windows', 'wince', 'darwin'): @@ -61,5 +67,5 @@ def AddOptions(opts): opts.Add(EnumOption('platform', 'target platform', default_platform, allowed_values=('linux', 'cell', 'windows', 'winddk', 'wince', 'darwin', 'embedded'))) opts.Add('toolchain', 'compiler toolchain', 'default') - opts.Add(BoolOption('llvm', 'use LLVM', 'no')) + opts.Add(BoolOption('llvm', 'use LLVM', default_llvm)) opts.Add(BoolOption('dri', 'build DRI drivers', default_dri)) -- cgit v1.2.3
