使找不到当前交叉编译器

Question

I'm using a make file to compile a kernel for an arm/Xilinx platform.

I'm setting an env variable CROSS_COMPILE which the make file will then use.

I'm trying to use a cross compiler, which is present on my system, called arm-xilinx-linux-gnueabi-gcc by setting the env var in the following ways;

export CROSS_COMPILE=/opt/Xilinx/SDK/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-

export CROSS_COMPILE=arm-xilinx-linux-gnueabi-

The make file should append gcc .

The error given for both is

make: /opt/Xilinx/SDK/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc: Command not found
scripts/kconfig/conf --silentoldconfig Kconfig
make: /opt/Xilinx/SDK/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc: Command not found

  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.

make[1]: *** [kernel/bounds.s] Error 127
make: *** [prepare0] Error 2

It works with other arm cross compilers but this one.

Why is this?

According answers you gave in comments, you are trying to run a 32bits executable on a 64bits host platform.
