Description Marcelo Roberto Jimenez 2020-03-17 14:16:49 UTC

Hi,

I am having a problem while compiling the linux kernel with a toolchain generated by buildroot. The git tag for the toolchain build is "2019.11":

PIG_KERNEL_MAKE=/home/user/prog/scripts/pig-kmake.sh --ccache /home/user/prog/tmp/arm /home/user/prog/tmp/linux ARCH=arm CROSS_COMPILE=arm-buildroot-linux-gnueabi-
PWD=/home/user/prog

make[1]: Leaving directory '/home/user/prog/tmp/arm'
make: *** [Makefile:146: sub-make] Error 2

The problem seems to be the same as the one reported here: https://github.com/bootlin/toolchains-builder/issues/17

The toolchain has been generated in one machine and is beeing used in another different machine. Somehow bison still keeps its absolute path dependency.

Best regards,
Marcelo.

Also, a suggestion for a quick workaround while the bug is being addressed is welcome ;)
