From b11911dddf2fd58e24c808da26105cb1e1bce722 Mon Sep 17 00:00:00 2001 From: Olivier Blin Date: Sat, 15 Dec 2012 01:58:59 +0100 Subject: [PATCH] configure: do not detect incorrect cross-compiler On Ubuntu 11.04, configuring with --build=x86_64-unknown-linux-gnu --host=x86_64-linux-gnu finds a wrong cross-compiler: checking for cross-compiler... x86_64-x86_64-pc-linux-gnu-gcc This happens because of a dash vs underscore inconsistency in configure.in: host=x86_64-pc-linux-gnu host_cpu=x86_64 host_os=linux-gnu which ${host_cpu}-${host_os}-gcc >/dev/null 2>&1 && echo ${host_cpu}-${host-os}-gcc This bug has been introduced in the initial --with-host support from 2002, commit eb267ade29c9a49c07b1c33dc9bf7a6790217400 This configure command is about "cross-compiling for i586", where the system compiler is used, which just -m32 additional options. The --build value comes from config.guess. --- configure.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configure.in b/configure.in index e397dade..4af917be 100644 --- a/configure.in +++ b/configure.in @@ -31,7 +31,7 @@ then which ${program_prefix}gcc >/dev/null 2>&1 && CC=${program_prefix}gcc which ${host_cpu}-${host_os}-gcc >/dev/null 2>&1 \ - && CC=${host_cpu}-${host-os}-gcc + && CC=${host_cpu}-${host_os}-gcc which ${host_cpu}-${host_vendor}-${host_os}-gcc >/dev/null 2>&1 \ && CC=${host_cpu}-${host_vendor}-${host_os}-gcc -- 2.47.1
