Issue Building Asterisk

[zap]

Hello, I was trying to build Asterisk from source on a Raspberry Pi and ran into this little error after issuing a make command.

$this->bbcode_second_pass_code('', '[pi@alarmpi asterisk-1.4.44]$ make
[CC] src/add.c -> src/add.o
gcc: error: unrecognized argument in option '-march=armv6l'

')

I'm a little new to reading into make errors and get the feeling that gcc is not liking the -march=armv6l…any suggestions on how to correct these two errors?

Why are you building from source when it is easier to modify a PKGBUILD If you dont like something about the pckage in repos. There is also AUR which may already have what you are looking for. If you still want to do it your way then see what march is used under /etc/makepkg.conf

[zap]

Simple. Current LTS version of Asterisk is 1.8 (available in the AUR). Oldest version available in the AUR is 1.6. I need a module that Asterisk stopped supporting in 1.4 (which is why I'm building the lastest version of 1.4).

The only reference to -march in the makepkg.conf file is in the CFLAGS and CXXFLAGS line which are stated as -march=armv6

[moonman]

Ok, makes sense.
That is what all the packages are built with. If you want to be more specific: -mcpu=arm1176jzf-s

[zap]

So I guess the question still remains, where is gcc grabbing "-march=armv6l"?

Once upon a time there was a weird patch https://raw.githubusercontent.com/archlinuxarm/PKGBUILDs/337006a392125411bff50f8b2b2aa7227aba8c1c/aur/asterisk/arm.patch

Don't know if this will work, but worth a try (if you haven't tried this already)
$this->bbcode_second_pass_code('', 'export CFLAGS="-march=armv6 -mfloat-abi=hard -mfpu=vfp -O2 -pipe -fstack-protector --param=ssp-buffer-size=4"
export CXXFLAGS="-march=armv6 -mfloat-abi=hard -mfpu=vfp -O2 -pipe -fstack-protector --param=ssp-buffer-size=4"
export LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro"')
and then you run make.

EDIT: I tried it. The hack is to edit "makeopts" after running ./configure to change arch to armv6. It still errors out with assembler errors:
$this->bbcode_second_pass_code('', ' [AS] src/k6opt.s -> src/k6opt.o

Source might be too outdated. I did not dig any deeper and only tried on armv7 in armv6 chroot. Try it on the Pi just in case...

EDIT2: - Install gsm: pacman -Sy gsm
- Configure with
$this->bbcode_second_pass_code('', './configure --with-gsm=/usr')
- Edit "makeopts" and replace armv6l with armv6 (about 3 instances I think)
- run make

It built for me, don't know if it works or not. Good Luck.

That has seemed to have worked.
