I have some compilers for different architectures:
$ > whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/share/man/man1/gcc.1.gz
$ > whereis arm-linux-gnueabi-gcc
arm-linux-gnueabi-gcc: /usr/bin/arm-linux-gnueabi-gcc /usr/share/man/man1/arm-linux-gnueabi-gcc.1.gz
$ > whereis arm-linux-gnueabihf-gcc
arm-linux-gnueabihf-gcc: ~/.local/bin/arm-linux-gnueabihf-gcc
gcc is for my workstation. It was installed in system path.
arm-linux-gnueabi-gcc is for ARM target without hard float. It was installed in system path too.
arm-linux-gnueabihf-gcc is for ARM target with hard float. It was installed in my $(HOME)/.local/ directory.
And I have added this directory to binary path in the .bashrc script:
export PATH="$HOME/.local/bin:$PATH"
The system command whereis works true for all this compilers and shows valid path to binary executable file.
I wanted to compile some project for ARM with help arm-linux-gnueabihf-gcc compiler, but I have received this:
as: unrecognised option '-mcpu=cortex-a53'
Error during assembler. Seems that my build system wish to use assembler for my x86, not arm-linux-gnueabihf-as.
After the installing arm-linux-gnueabihf to ~/.local into the one some directories are appeared:
~/.local> ls -l
arm-linux-gnueabihf/
bin/
gcc-linaro-5.3.1-2016.05-linux-manifest.txt
include/
lib/
libexec/
share/
If i will go to bin/ I will see the binbary files:
arm-linux-gnueabihf-addr2line* arm-linux-gnueabihf-cpp* arm-linux-gnueabihf-gcc-ar* arm-linux-gnueabihf-gdb* arm-linux-gnueabihf-nm* arm-linux-gnueabihf-size* isort*
arm-linux-gnueabihf-ar* arm-linux-gnueabihf-elfedit* arm-linux-gnueabihf-gcc-nm* arm-linux-gnueabihf-gfortran* arm-linux-gnueabihf-objcopy* arm-linux-gnueabihf-strings* pylint*
arm-linux-gnueabihf-as* arm-linux-gnueabihf-g++* arm-linux-gnueabihf-gcc-ranlib* arm-linux-gnueabihf-gprof* arm-linux-gnueabihf-objdump* arm-linux-gnueabihf-strip* pyreverse*
arm-linux-gnueabihf-c++* arm-linux-gnueabihf-gcc* arm-linux-gnueabihf-gcov* arm-linux-gnueabihf-ld* arm-linux-gnueabihf-ranlib* epylint* runtest*
arm-linux-gnueabihf-c++filt* arm-linux-gnueabihf-gcc-5.3.1* arm-linux-gnueabihf-gcov-tool* arm-linux-gnueabihf-ld.bfd* arm-linux-gnueabihf-readelf* gdbserver* symilar*
This path was added to $PATH.
But if i will go to ./arm-linux-gnueabihf/bin and will do ls, i will receive empty directory.
I can overcome the error, if i will add some symbolic links to this directory:
ar -> ../../bin/arm-linux-gnueabihf-ar*
as -> ../../bin/arm-linux-gnueabihf-as*
gcc -> ../../bin/arm-linux-gnueabihf-gcc*
ranlib -> ../../bin/arm-linux-gnueabihf-ranlib*
strip -> ../../bin/arm-linux-gnueabihf-strip*
...
After this my assembler error disappears and I can successfully compile project for ARM-target. But after this I can't compile anything for my workstation x86.
Could anyone explain me what i should to do to successful compiling and for ARM and for x86, please?
UPD: I have the Makefile for ARM:
CROSS_COMPILE = arm-linux-gnueabihf-
CC = $(CROSS_COMPILE)gcc
AS = $(CROSS_COMPILE)as
INCLUDES = -I./
SRC = main.c
TARGET = my-arm-target
all: $(SRC)
$(CC) $(INCLUDES) -o $(TARGET)
And the same file for x86, but without CROSS_COMPILE variable:
CC = gcc
AS = as
INCLUDES = -I./
SRC = main.c
TARGET = my-x86-target
all: $(SRC)
$(CC) $(INCLUDES) -o $(TARGET)
