compile error + creating sd card

[starmagoo]

I want to compile RBX 4.1 for a RPi3.

make recalbox-${arch}_defconfig cause no errors.

make provides the following:

make[1]: Entering directory '/git/recalbox-buildroot-rpi3/output/build/dosbox-r3989'
make[1]: *** No targets specified and no makefile found.  Stop.
make[1]: Leaving directory '/git/recalbox-buildroot-rpi3/output/build/dosbox-r3989'
package/pkg-generic.mk:195: recipe for target '/git/recalbox-buildroot-rpi3/output/build/dosbox-r3989/.stamp_built' failed
make: *** [/git/recalbox-buildroot-rpi3/output/build/dosbox-r3989/.stamp_built] Error 2

Any ideas what I'm doing wrong? Anything missing?
arch is set to rpi3

[supernature2k]

remove dosbox from package list in the makefile

[Substring]

remove BR2_PACKAGE_DOSBOX from .config, more precisely

[starmagoo]

Ok this works. thanks for your answer.

Now I want to but all files to the SD-Card. In the Wiki guide there is the talk of 3 .tar.xz files.
I have 2 .tar.xz files and 1 .img file.
I miss the file share.tar.xz

5521000 Sep  1 15:13 boot.tar.xz
1297322496 Sep  1 15:14 recalbox.img
193368100 Sep  1 15:13 root.tar.xz

The rescue system has no directory for rpi3:

ls -l recalbox-rescue/output/os/
total 8
recalboxOS-rpi1
recalboxOS-rpi2

Which files do I need for the sd card?

regards

[supernature2k]

Best is to burn the .img to your SD card with Win32DiskImager

[Substring]

depends if you want to update or start a new SD from void

[starmagoo]

I would try both.
If I would start from scratch, I need to burn the img to the sd card like @supernature2k said?
Do I only need ´´root.tar.xz´´ for an update?

[Substring]

For an update, recalbox won't do anything if it doesn't have both the [br]oot.tar.xz in the right folder

Anyway, i don't know how good you know reaclbox, but if you wanna upgrade from a 4.0, the upgrade process to 4.1 is not yet fully ready. It will work, of course, but we didn't manage the update of some special files yet

[starmagoo]

Ok a clean installation seams to be the best choise.

Thx for assistance. Installation process worked. Now I only need to port the scores and the ROM's?

[Substring]

don't expect too much support from the team, on 4.1 we are not yet finished developping it. Support will start once beta (or even alpha) starts

[starmagoo]

No Problem, that's comprehensible.

Hi! I'm trying to compile the project for the very first time and after removing the dosbox package I get this error with freeimage:

Any ideas?

[Substring]

@paradadf Had that on my very first compilations too using virtual box. Switching to native Linux did the trick

[paradadf]

@subs I installed Ubuntu 16.04 32bit on an old laptop specially to try this :S

[Substring]

@paradadf can't check for now what i'm thinking about. But the idea is to edit CCFLAGS or LDFLAGS in the package and force -fPIC. Or in the makefile even ... Buildroot is supposed to handle that itself, so i think you may encounter this problem again later in the building process

[digitaLumberjack]

Could you test with the docker build @paradadf ?

https://github.com/recalbox/recalbox-docker-build

[paradadf]

@digitaLumberjack I'll try it tonight, thanks!

[paradadf]

Hmmm... it seems I won't be able to compile it with the docker. I'm using Ubuntu 16.04 32bit and just read this on the docker documentation:

Docker requires a 64-bit installation regardless of your Ubuntu version.

Saldly, my old laptop doesn't support it.
