so... you aren't actually cross-compiling, am I right? That's weird then, configure should pick up all the right settings. I'm curious to see the emitted code around the crash site. If you use gdb, something like `x/100i $pc-0x40` should do the trick. -Bernhard ________________________________________ From: Angelo Compagnucci <angelo.compagnu...@gmail.com> Sent: Tuesday, May 23, 2017 6:35:06 PM To: Bernhard Urban Cc: mono-devel-l...@lists.ximian.com Subject: Re: [Mono-dev] Crosscompiling Mono 5.0.0.100 Hello Bernhard, The recpie is this one: ################################################################################ # # mono # ################################################################################ MONO_VERSION = 5.0.0.100 MONO_SITE = https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdownload.mono-project.com%2Fsources%2Fmono&data=02%7C01%7Cbeurba%40microsoft.com%7C25ae3075088c4b176de708d4a1f9c451%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636311541495053555&sdata=gh4wrnniTrAEH5C7lGkDBF8dLLusjvGNkJR9KCkHzH4%3D&reserved=0 MONO_SOURCE = mono-$(MONO_VERSION).tar.bz2 MONO_LICENSE = GPL-2.0 or MIT (compiler, tools), MIT (libs) or commercial MONO_LICENSE_FILES = LICENSE mcs/COPYING eglib/COPYING \ external/Newtonsoft.Json/Tools/7-zip/copying.txt MONO_INSTALL_STAGING = YES ## Mono native # patching configure.ac MONO_AUTORECONF = YES # Disable managed code (mcs folder) from building MONO_CONF_OPTS = --with-mcs-docs=no \ --with-ikvm-native=no \ --enable-minimal=profiler,aot \ --disable-mcs-build \ --with-xen_opt=no \ --disable-btls \ --enable-static # The libraries have been built by the host-mono build.
