I'm not 100% sure that it's needed, but if it can't process the examples/testxxLexer.l file supplied with flex without calling it (as seen here) it does suggest that it is required. 38565 1 enrico.scholz 2013-11-05 18:03:42 +0000 will EXTRA_OECONF += " ac_cv_path_M4=${M4}" EXTRA_OEMAKE += " m4=${M4_class-native}" solve it? 38566 2 bluelightning 2013-11-05 18:21:41 +0000 That would be preferable to the profile.d-based fix, however it's somewhat unorthodox to use overrides in the manner the second line does. We do also need the extra RDEPENDS as far as I can tell. 38568 3 enrico.scholz 2013-11-05 18:53:14 +0000 When it is really too unorthodix, then add add a helper variable M4NATIVE = "${STAGING_BINDIR_NATIVE}/m4" M4_class-native = "${M4NATIVE}" EXTRA_OECONF += "ac_cv_path_M4=${M4}" EXTRA_OEMAKE += "m4=${M4NATIVE}" About which RDEPENDS are you speaking? By using fix above, all the 'create_wrapper' appends can be removed. 38569 4 enrico.scholz 2013-11-05 18:59:44 +0000 By looker further into it, the M4 variable can be removed completely when 'create_wrapper' scripts are removed. So, add EXTRA_OECONF += "ac_cv_path_M4=${bindir}/m4" EXTRA_OEMAKE += "m4=${STAGING_BINDIR_NATIVE}/m4" and remove 'M4* = ...' and the do_install_append...() 38947 5 laurentiu.palcu 2013-11-20 15:43:22 +0000 Merged in master: http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=9a6ee8b447ee6070b23bb11fd3dd7fabf0d9ab80
