gcc: error: unrecognized command line option

Question

I'm trying create an u-boot image file. But have i have some error.

gcc version: 7.3.0

make PATH=/opt/CodeSourcery/Sourcery_G++_Lite/arm-2011.03-41-arm-none-linux-gnueabi:$PATH
export CROSS_COMPILE=arm-linux-gnueabihf-(or arm-none-linux-gnueabi)
make ARCH=arm xilinx_zynq_defconfig
make -j ARCH=arm UIMAGE_LOADADDR=0x8000 uImage

ERROR:

gcc: error: unrecognized argument in option ‘-mabi=aapcs-linux’
gcc: note: valid arguments to ‘-mabi=’ are: ms sysv
gcc: error: unrecognized command line option ‘-mlittle-endian’; did you mean ‘-fconvert=little-endian’?
gcc: error: unrecognized command line option ‘-mfpu=vfp’; did you mean ‘-mcpu=’?
  CC      scripts/mod/devicetable-offsets.s

How can i fix? any idea?

Solution 1

A more deterministic way of pointing to the exact toolchain you want to use is to provide its full prefix when setting CROSS_COMPILE. This will avoid possible path-related errors, and the information on which exact toolchain was used for building will be embedded in your build script.

Full example - installing official Arm gcc toolchain and retrieving/building u-boot 20.04 for xilinx_zynq_virt (use your own u-boot and defconfig):

# gcc 9.2.0
mkdir -p /opt/arm/9
wget 'https://developer.arm.com/-/media/Files/downloads/gnu-a/9.2-2019.12/binrel/gcc-arm-9.2-2019.12-x86_64-arm-none-eabi.tar.xz?revision=64186c5d-b471-4c97-a8f5-b1b300d6594a&la=en&hash=5E9204DA5AF0B055B5B0F50C53E185FAA10FF625'
tar Jxf gcc-arm-9.2-2019.12-x86_64-arm-none-eabi.tar.xz -C /opt/arm/9

# u-boot
wget https://github.com/u-boot/u-boot/archive/v2020.04.tar.gz
tar zxf v2020.04.tar.gz
cd u-boot-2020.04

I hope this help.

Your PATH is pointing to some 2011 GCC cross compiler. You need at least GCC 6 which was released in 2016. Please, install a current release of GCC.

On Debian or Ubuntu the C compiler for the host system and the cross compiler are separate packages. You can install the cross-compiler for 32bit and 64bit ARM with:

sudo apt-get install gcc-arm-linux-gnueabihf
sudo apt-get install gcc-aarch64-linux-gnu

As the compilers are installed in /usr/bin it is sufficient to set the CROSS_COMPILER variable like

export CROSS_COMPILE=arm-linux-gnueabihf-

or

export CROSS_COMPILE=aarch64-linux-gnu-

I'm not a uboot expert but it looks like you are not correctly cross compiling but instead end up using the native toolchain. Probably haven't set CROSS_COMPILE env var.

[EBBulut]

I'm setting with this; export CROSS_COMPILE=arm-linux-gnueabihf- Edit my command now.

[kaylum]

make PATH=... Is that really what you ran?

[EBBulut]

Yes. i did try export PATH=.. still same result.

[EBBulut]

Thanks. i did install gcc-8,2 but i need change gcc path, i guess. Do u know how can i change gcc path ?

[Xypron]

The host GCC and the GCC cross compiler are separate packages. For Ubuntu I have added a description above.

[EBBulut]

Thank u @Frant. its so helped.
