From 3b7111b30dbd9a4cdd141b594164da18c15ae970 Mon Sep 17 00:00:00 2001 From: Serhii Popovych Date: Fri, 31 Mar 2017 11:46:58 +0000 Subject: automake: Adjust shebang lines to remove interpreter path hardcode If build host perl (and other tools) is old and we use some kind of toolchain to provide recent perl/python/etc to the OE build we still locked to use build host perl due to hardcoded shebang lines in automake scripts. Behaviour was observed with Enterprise Linux 6 and devtoolset toolchain from SCL (Software Collections) used to provide recent version of perl (not provided with default buildtools-tarball). Pass /usr/bin/env perl in ac_cv_path_PERL configuration variables for class-native and class-nativesdk. Use patch to automake to replace -w option in shebang line with modern way to enable warnings on perl (i.e. "use warnings"). Also add nativesdk-autoconf to RDEPENDS to bring runtime dependencies inline with other targets. Note that ac_cv_path_PERL must be valid perl interpreter path since configure will check perl version and Flock implementation. It is not possible currently to use nativeperl from native sysroot because automake does not DEPENDS on perl-native (and doing so fails due to circular dependencies). Only possible solution is to overwrite shebangs with nativeperl somewhere at do_install() and update RDEPENDS for class-native. Or add perl symlinks to nativeperl in sysroot. For now it seems good to use perl found by /usr/bin/env from automake-native.
