[Buildroot] build problems

[Steve Calfee]

Hi John,

I can't speak for Tim. My problems are that stuff I don't know about and don't know how to change - entirely unrelated to embedded kernel issues cause my build to break. I have a newly svn update'd source tree. I would just once like to build a default config before I start customizing. I cannot get through a make. Thats why I keep asking if anyone has a default config (for an arm926) that will build with the current (or any previously tagged) svn tree. I run Ubuntu feisy and think I have all the necessary host tools.

This sequence was copied from the http://www.linux4sam.org/twiki/bin/view/Linux4SAM/BuildRoot website where I do:

$ make menuconfig
$ make at91sam9260dfc_defconfig
$ make > at91sam9260dfc.log 2>&1

and here is a snip of the log file:

cp /home/calfee/buildroot/arm/buildroot/toolchain_build_arm/ccache-2.4/ccache /home/calfee/buildroot/arm/buildroot/build_arm/staging_dir/usr/bin

# Otherwise, relative paths for include dirs break.

collect2: ld returned 1 exit status
make: *** [/home/calfee/buildroot/arm/buildroot/project_build_arm/at91sam9260dfc/root/usr/bin/sstrip] Error 1
[1]+  Exit 2                  make > at91sam9260dfc.log 2>&1

 
 Then I checked to see if sstrip exists:
 
 calfee at squiggy-linux:~/buildroot/arm/buildroot$ find . -name sstrip
./build_arm/staging_dir/usr/arm-linux-uclibc/bin/sstrip
./toolchain/sstrip

calfee at squiggy-linux:~/buildroot/arm/buildroot$ ./build_arm/staging_dir/usr/arm-linux-uclibc/bin/sstrip
Usage: sstrip FILE...
sstrip discards all nonessential bytes from an executable.


And it does, so the path in the makefile must be wrong.

Indeed:
calfee at squiggy-linux:~/buildroot/arm/buildroot$ /home/calfee/buildroot/arm/buildroot/project_build_arm/at91sam9260dfc/root/usr/bin/sstrip
bash: /home/calfee/buildroot/arm/buildroot/project_build_arm/at91sam9260dfc/root/usr/bin/sstrip: No such file or directory

So in this case it seems something has changed in directory naming and somewhere the makefiles are broken. I don't think I have any changed files in my source tree.

As one new to the current buildroot system, I have no idea how to proceed.
