cross compiling for armv7

Hi folks,

I'm trying to cross-compile u-boot-rockchip on my arch linux system, kernel 4.17.5-1 x86_64, toolchain arm-unknown-linux-gnueabihf- setup according to the cross compile wiki, but I get multiple error messages about missing compiler-gcc8.h:

make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabihf- menuconfig
Generating include/autoconf.mk

 #include gcc_header(__GNUC__)
 ^~~~
compilation terminated.

The following gcc packages are installed:

core/gcc 8.1.1+20180531-1 (base-devel)
core/gcc-libs 8.1.1+20180531-1 (base) 

I'm using the ARMv7l hard-float linked in the wiki.

How can I fix this  ?

Re: cross compiling for armv7

When I cross compile, I ssh into the target machine (armv7 or aarch64) and run distcc on my x86_64 box.  Is that an option?  The AUR contains the Arch ARM toolchain: https://aur.archlinux.org/packages/dist … rm-armv7h/

Re: cross compiling for armv7

As OP I'm on the same band wagon. Trying to compile for RockChip3288 on a Tinker Board.
What to set up to the master in order to compile the kernel?
I've tried to set a cross compiling, but is most like OP, but I downloaded this kernel. I'd like to fix the WiFi AP function.

I could boot the ALARM, by the help of a debian kernel (TinkerOS or Armbian), but I can't get the ALarm kernel working.
Then If I boot Alarm, as I mentioned, I don't have WiFi at all. It seems that the firmware is missing. Also some problem to get the wired connection working and internet sharing, so I can't do much further.

Re: cross compiling for armv7

There is also an ARM toolchain in the official repo arm-none-eabi-gcc

Re: cross compiling for armv7

I solved my problem to cross compile, but I strangely found some dependencies which are mutually exclusive, but requested.
So to get arm-linux-gnueabihf-gcc it's required to install arm-linux-gnueabihf-gcc-stage1 that later must supersede by arm-linux-gnueabihf-gcc-stage2, with a relevant volume of megabytes.
