Autotools is definitely a pain when cross compiling. I'm probably gonna build it in a chroot (well systemd-nspawn, but same thing) for now using qemu-arm-static, as Jeff and Ken sugested. That is how I did it last time when I compiled FS for rpi (few months back), but it's slow and I wanted to try cross-compiling it (and I'm not giving up on this idea just yet). I'm gonna compare config.cache between cross compile and native to see if there are any glaring differences. Did anyone have a chance to look at that backtrace, any ideas whats going on? Also I found this wiki page: https://wiki.freeswitch.org/wiki/Raspberry_PI-specific_documentation It references a script (https://github.com/bmanojlovic/rpi-cross-compile/blob/master/debootstrap_ras...) which seems to create a "mixed" chroot where the compiler is running on x86 while everything else is running emulated with qemu. At least that is what I think it does (by looking at the script), haven't used it yet. On 3 December 2013 22:46, Ken Rice <krice@freeswitch.org> wrote:
Even with SwitchPI I do not cross compile, never got it work properly that way, and tried various methods including distcc et al...
the problem with cross compiling is autotools is a pain to get working correctly in a cross compile environment you have to tell it most of the answers instead of letting it guess them...
I would just compile it under raspbian on a RPi or i.MX5 (this is what the Raspbian team was using last time I looked for building everything) and then go from there... yes it takes a while, but even so last time i tried to cross compile it, or qemu it, those were not that much faster then native

I'd suggest that you look into qemu as a cpu emulator. You can use that to chroot into an armv6 user land and compile freeswitch natively from there.

Hi all,
This weekend I tried my luck at cross-compiling freeswitch for raspberry pi (armv6). After a few bumps along the way (opened jiras for those) I managed to build it, but when running freeswitch on the target system it segfaults during startup.
I'm building on Fedora 19 x86_64 using the prebuilt toolchain from https://github.com/raspberrypi/tools (I can build a toolchain from source if anyone thinks it might be better). Raspbian debootstrap created base system is used as sysroot (also tried loop mounted raspbian image as sysroot).
My simple build environment setup script: http://pastebin.freeswitch.org/21698
The build process (source the script, configure and compile): ./bootstrap.sh . ~/fs-cc-env.sh ./configure --build=x86_64-redhat-linux --host=arm-linux-gnueabihf --with-sysroot=$SYSROOT make
make install didn't work (I guess it's kinda expected, didn't really look into it) so I just copied the binaries, libraries and modules to rpi. Also mod_spidermonkey and mod_xml_rpc were disabled. Didn't even try to build mod_spidermonkey and mod_xml_rpc failed to build (well it builds but makefile tries to run libs/xmlrpc-c/lib/expat/gennmtab/gennmtab which was compiled for arm and should have been x86, probably should create jira for this as well).
Console log when FS is started: http://pastebin.freeswitch.org/21699
and backtrace: http://pastebin.freeswitch.org/21700
Is my build environment sane? What am I missing, any hints? Has anyone successfully cross-compiled FS for raspberry pi?
Thanks, -- Dušan Dragić
