Upgrade raspberrypi's cross compile tool to gcc 8.3.0? #102
Comments
If you want I uploaded mine here. It should be 100% compatible with Buster. I have not experienced problems with it yet. |
@carlonluca unfortunately your toolchain is not compatible with buster: your binutils is not patched for multiarch. Your gcc is, so you get linker errors like this:
In order to fix this you need to apply http://bazaar.launchpad.net/~doko/binutils/pkg-2.24-debian/view/head:/patches/129_multiarch_libpath.patch to binutils source tree before building it. |
Can this be of any use for this?

@mtekeli all the download links for that are broken, but I expect it has the same problem. |
@ali1234 thanks for the info. I didn't encounter that error with any of my builds. How did you trigger that error? |
I tried to cross compile libgssdp from git master against a raspbian sysroot. |
I created a new repository which contains an updated toolchain with ARMv6 support. Tested it on a Raspberry PI Zero with Raspbian Buster, and it works perfectly. See: And the repo: I'm happy for any feedback. |
Does it cross compile the kernel correctly and the result run OK? That's usually a good test for a new toolchain. |
I did not test that yet. Honestly, I did not yet try to compile a kernel myself. @JamesH65 do you know any good tutorial or example which shows how to do that? |
The official RPi kernel building guide is here: https://www.raspberrypi.org/documentation/linux/kernel/building.md |
the toolchain according to ali1234 succeded to cross-compile qt 5.11.3 |
@martburg Could you please share how to make a cross-compiler for qt 5.11.3, in ubuntu please? |
@mahaju this toolchain here https://thebugfreeblog.blogspot.com/2019/09/raspbian-buster-gcc.html works for every Qt version I tested, up to 5.15.1. I tested for both Linux and Mac OS. |
Any plan to upgrade raspberrypi's cross compile tool to gcc 8.3.0? Some times, it's seriously slow to compile the source code on raspberry pi directly...
