[OpenWrt-Devel] Toolchain for armv7-ar?

[Florin]

I've got a toolchain (gcc-4.9.2 + binutils-2.26.1) running on armv7-a and
ipk packages  compiled with/for it: 

floring at huawei:~$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/opt/usr/libexec/gcc/arm-linux-gnueabi/4.9.2/lto-wrapper
Target: arm-linux-gnueabi
Configured with: ../configure --host=arm-linux-gnueabi
--target=arm-linux-gnueabi --prefix=/opt/usr --with-gmp=/opt/usr
--with-mpfr=/opt/usr --with-mpc=/opt/usr --with-isl=/opt/usr
--with-cloog=/opt/usr --enable-languages=c,c++,go,objc,obj-c++
--disable-multilib
LDFLAGS_FOR_TARGET=-Wl,--dynamic-linker=/opt/lib/ld-linux.so.3
LDFLAGS_FOR_HOST=-Wl,--dynamic-linker=/opt/lib/ld-linux.so.3
LDFLAGS=-Wl,--dynamic-linker=/opt/lib/ld-linux.so.3
Thread model: posix
gcc version 4.9.2 (GCC)

The architecture is a Huawei-ES880 (Cortex A9 without FPU) router running
Zyxmon's DD-WRT mod for Northstar platforms. I've even been able to compile
and run Xorg, GTK 2 and 3 and Qt 4.8.2 as optware on it, and I am  currently
working on upgrading gcc and "debianize" it. So I kinda run a complete linux
on this architecture.
I've started it from cross-compiling glibc and gcc and installing them on
scratch /opt filesystem, and to simplify things I used some of Zyxmon's
Qnapware (http://qnapware.zyxmon.org/binaries-armv7/); If you only need some
essential packages, this link would be enough.

I am doing it as a hobby, but my problem is that I don't have a large
traffic subscription so I cannot make it largely public. If you need more
than the packages in Qnapware, especially the native arm-v7a toolchain, then
I could share my work. Keep in mind that these embedded systems have limited
RAM so you need to setup at least 1GB of swap space and set TMPDIR variable
on external HDD directory for making all these work.
