Unable to compile for Allwinner H3

[bitartrate]

Hi, Uli,

I have become interested in compiling for the OrangePi H3. The makefile halts with error: "Makefile.h3:19: /home/kevin/devel/orangepi/allwinner-bare-metal/build.mk: No such file or directory" The closest I have come to getting past this error was to make an empty file 'build.mk' then add '#INCLUDE = ~/devel/orangepi/allwinner-bare-metal/build.mk' to the makefile. It satifies the missing file but ends without making a .bin file; at least not that I can find.

I do believe I have the necessary H3 toolchain installed.

build.mk is part of the allwinner-bare-metal git repo. It's in the "opi" branch, though. Maybe that's the problem...

[bitartrate]

That was half the problem. Thank you. Now I see I need to install crosstools-NG? as allwinner-bare-metal is looking for folder 'x-tools'.

[uli]

That is correct. The configuration file for the toolchain is crosstool-ng.config.

[bitartrate]

Unfortunately I am not finding the correct documentation for x-tool. I have crosstool-ng-1.24.0 installed but I am not able to find the docs to put that together with your allwinner-bare-metal opi branch.

[uli]

mkdir xyz
cd xyz
cp ../allwinner-bare-metal/crosstool-ng.config .config
ct-ng build

I am making headway. My latest effort looked like it was going to work but after the lengthy build log it ended in these errors:

In file included from ttbasic/video.h:13, from ttbasic/mcurses-config.h:18, from ttbasic/mcurses.cpp:18: h3/h3gfx.h: In member function 'void H3GFX::setPixels(uint32_t, pixel_t, uint32_t)': h3/h3gfx.h:84:5: error: 'memcpy' was not declared in this scope memcpy((pixel_t )address, data, len * sizeof(pixel_t)); ^~ h3/h3gfx.h:84:5: note: 'memcpy' is defined in header ''; did you forget to '#include '? h3/h3gfx.h:10:1: +#include

I wish I had more experience... We are past the previous error. Now make ends with: make -f Makefile.h3 make[1]: Entering directory '/media/kevin/500gbssdpart2/OpenSourceComputers/BasicEngineComputer/Firmware/basicengine-firmware' make[1]: No rule to make target '/home/kevin/devel/orangepi/allwinner-bare-metal/libos.a', needed by 'basic.elf'. Stop. make[1]: Leaving directory '/media/kevin/500gbssdpart2/OpenSourceComputers/BasicEngineComputer/Firmware/basicengine-firmware' Makefile:31: recipe for target 'h3' failed make: [h3] Error 2

I see that libos.a and linker.ld are referenced in build.mk but I do not see where these are built.

Thank you.

Hey Uli, unfortunatelly I'm also not able to the get the firmware compiled for the h3. I followed the short instructions on basicengine.org and your hints in this issue, but I still get the following error, when when using: ninja -f build.ninja.h3

ninja: error: '.git/index', needed by 'ttbasic/version.h', missing and no known rule to make it

Any clue, what the problem might be. Help would be greatly appreciated :-)

Thanks a lot

I suppose you downloaded the repo as a zip file or something like that. Use git to check out the source tree, and you will have a .git directory with an index file in it. (I'll close this because it's not a bug. Please ask any follow-up questions in the forum. Thank you.)
