aarch64-linux-gnu-gcc Cross Complier for arm fails

./configure --host=arm-elf-linux  CC=aarch64-linux-gnu-gcc --disable-sdl --disable-ffmpeg --disable-v4l2 --disable-openh264 --disable-libwebrtc --disable-libyuv

make dep && make

"file in wrong format" Err:

$ file main.o 
main.o: ELF 64-bit LSB relocatable, x86-64,

$file other *.o
sip_uri.o: ELF 64-bit LSB relocatable, ARM aarch64,

so main.o file format is x86-64 , but other .o files formate are ARM aarch64

but ....i still dont know how to solve that ( change the main.o file format)

the segment of main.o in Makefile and i m sure the Problem at line:287

Solution

  • Some of the libraries to link may not be built with the same toolchain. You can check with objdump.

    Example (The "file format" may not be the exact result in your case):

    $ aarch64-linux-gnu-objdump -TC libz.so

libz.so:     file format elf64-littleaarch64

    Please confirm that the "file format" of all the libraries should match your toolchain.

    Update:

    You can see the compliling message for main.cpp when make

    g++ -c -DPJ_AUTOCONF=1 -g -O2 -Wall -DPJ_AUTOCONF=1 -O2 -DPJ_IS_BIG_ENDIAN=0 -DPJ_IS_LITTLE_ENDIAN=1 -I../include -I../../pjlib/include -I../../pjlib-util/include -I../../pjnath/include -I../../pjmedia/include -Wall -DPJ_AUTOCONF=1 -O2 -DPJ_IS_BIG_ENDIAN=0 -DPJ_IS_LITTLE_ENDIAN=1 -I../include -I../../pjlib/include -I../../pjlib-util/include -I../../pjnath/include -I../../pjmedia/include
    -o output/pjsua2-test-aarch64-linux-gnu/main.o
    ../src/pjsua2-test/main.cpp

    It should not be g++. It should be aarch64-linux-gnu-g++.

    Please try the following steps:

    1. Add CXX=aarch64-linux-gnu-g++ in configure command line and run again
    2. Confirm your makefile will use $(CXX) to compile cpp files, not g++
