like in the linux kernel build
make O=builds/arm
builds the result to the specified output directory
is this supposed to work for uboot also ?
doesn't seem to work for me, i've fetched older tar files and same problem
maybe my environment?
fedora32
5.10.13-100.fc32.x86_64
GNU Make 4.2.1
the O=<dir> does mostly work on older uboot like from ~2010 though....
thought i'd ask as debugging the make process is,well umm...horrible,
(i've inserted some extra debug print codes in gnu make (it self no code to be praised about!
esp when so much open source depends on it!!)
so atm, a bit of a rabbit hole........should I persist?
Can you provide a sample failure? The last "make O=... fails" I saw was because they were passing ARCH= which isn't valid for U-Boot and specifically breaks if you're say building for an aarch64 platform as in the linux kernel you would do ARCH=arm64 but it's all "arm" here. Thanks!
so ok, i'v dropped using the ARCH= still
All the configs i tried failed:
make O=builds/rpi2 rpi_2_defconfig make O=builds/rpi2 mrproper <==tried this too
make O=builds/rpi2 -w -d V=1 CROSS_COMPILE=arm-none-eabi- qemu_mips_defconfig orangepi_zero_defconfig
qemu_arm_defconfig
Of course the builds all work just fine without O=, and results in the main directory.
So this is not just a problem on my machine?, i guess everyone just uses it like so ?
anyway i am sufficiently annoyed with it, i'll have a go at finding out why......
I don't know what's going on with your local environment. For me, I just now did: make O=builds/rpi2 -w -d V=1 CROSS_COMPILE=<my path to it> rpi_2_defconfig all and it completed. Perhaps you have something set in your environment? It's hard to say without seeing your error message.
