Arm-Linux-Gnueabi Compiler Options

Cross compiling with arm-linux-gnueabihf

You are pointing to your native header files directory, /usr/include, in your build command. This is very likely the cause of your problem. Try this command instead:

~/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -Isrc -std=c++11 -Wall -Wno-unknown-pragmas -O0 -g3 -D__DEBUG_BUILD__ -DDEVELOPMENT -MMD -c -o "Debug/src/BatteryStatus.o" "src/BatteryStatus.cpp

The default directories used by the toolchain can be displayed using:

echo | /opt/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -v -x c -E -

Using built-in specs.

That is, on my system, the correct, default directories for the header files would be:

 /opt/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/8.3.0/include
 /opt/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/8.3.0/include-fixed
 /opt/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/8.3.0/../../../../arm-linux-gnueabihf/include
 /opt/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/../arm-linux-gnueabihf/libc/usr/include

and not /usr/include.

Change default ARM gcc option to thumb

You can "mask" the executable file /usr/bin/arm-linux-gnueabi-gcc with your own script that is named the same inside /usr/local/bin.

• Create a file /usr/local/bin/arm-linux-gnueabi-gcc
• With the content
  
  
  • #!/bin/sh
  • /usr/bin/arm-linux-gnueabi-gcc -mthumb "$@"
• Add executable permissions to /usr/local/bin/arm-linux-gnueabi-gcc

Because PATH should list /usr/local/bin directory before /usr/bin, when you type arm-linux-gnueabi-gcc without the path in your console, your script will chosen first and will execute the real arm-linux-gnueabi-gcc executable with the additional option.

Compiling with arm-fsl-linux-gnueabi-gcc: int64_t is 32 bit long

Based on your comment.

Try 0xFFFFFFFFFFFFFFFFLL or -1

Add prefetch capability to target of arm-linux-gnueabi-g++

As @Notlikethat suggested, compiling with -march=armv7-a solved the issue. Now there is a pld instruction in the assembly output.

$ arm-linux-gnueabi-g++-4.7 -g -O3 -std=c++11 -static -S -march=armv7-a main.cpp -D some_definition
$ cat main.s | grep pld
pld [r0, #0]
