I am using ubuntu 14.04 and have installed

$ sudo apt-get install lib32stdc++6 lib32z1-dev lib32z1 lib32ncurses5
lib32bz2-1.0

I could not install ia32-libs due to package unavailability from ubuntu 14.04 repo

similarly,

sudo apt-get install sed dos2unix dtrx mono-complete git lib32z1 lib32ncurses5 lib32bz2-1.0 libc6:i386 libc6-i386 libstdc++6:i386 libncurses5:i386 libz1:i386 libc6-dev-i386 device-tree-compiler

except uname package, I have all other packages in my PC.

Any suggestions to solve this issue?

thanks,
prabhuraj

Hi Prabhuraj,


The "bad value (armv5) for -march= switch" error means that the the gcc for x86 is invoked instead of arm's cross compiler.
This happens because CROSS_COMPILE is empty in u-boot make command.
It seems there is some problem with including the variables from tools_path.mk properly (for example uboot_PATH you exported
manually is set there and also A15_TOOLCHAIN_PREFIX which is used for CROSS_COMPILE), but I am not sure what could be the reason for this.

Which MAKECONFIG you have set in Rules.make?

Regards,
Yordan

Thanks Yordan.

I am using tda2xx_evm_linux_all. I have already checked the tools_path.mk. I also edited the paths with my absolute src directory path, just to see if it helps.

I still see the same problem.

But, when I tried to compile the uboot and kernel code from their respective directories (eg os_tools/linux/kernel/omap) then it compiles properly. 

I want to compile from top level build directory.

Please provide your suggestions.

regards,
Prabhuraj
