Problems with pre-built GNU8 in Windows

Hi,

I tried to use gcc from gcc-arm-8.2-2018.08-i686-mingw32-aarch64-elf.tar.xz in Windows 10 but encountered the following problems:

I was not able to extract the files from the above tar successfully in Windows because the tar contains symbolic and hard links. As a workaround I first extracted the files in Ubuntu and then copied the files to an USB stick with ‘cp -RL -t /media/my_user_name/my_USB .’. Using this USB stick I was able to move all the gcc files to my Windows PC.
Now I was able to compile my test files successfully in Windows except when I used the option ‘-mabi=ilp32’ instead of '-mabi=lp64'. When compiling with ilp32 I get an error: ‘cc1plus.exe: error: assembler does not support -mabi=ilp32’. The command I used for compiling was ‘aarch64-elf-gcc -mcpu=cortex-a53 -mabi=ilp32 -c my_test.cpp’. The exact same command compiles without errors in Ubuntu with the gcc from gcc-arm-8.2-2018.08-x86_64-aarch64-elf.tar.xz.

Any suggestions how to get compiling with gcc8 and -mabi=ilp32 working in Windows?

Dear Jyrki,

Thank you for your feedback.

Regarding point 1) Which program/application have you used to extract tar.gz files we've provided ?

Regarding point 2) I will try reproduce and get back to you. Your my_test.cpp is just a plain "hello world" application I presume.

kind regards

Hi,

Thanks for the response.

1) I have been using WinZip version 19.5 to extract the tar.gz files. It works fine for example for gcc-linaro-7.3.1-2018.05-i686-mingw32_aarch64-elf.tar.xz from the Linaro site. Anyway, it took me some time to figure out what my problem was with gcc 8.2 tar.gz and to find a workaround (I'm only a casual user of Linux) so I thought to post my solution here if anyone else would encounter the same problem.

2) The content of my_test.cpp is below. I was also using the -c option for compile only.

int main()
{
return 1;
}

Regards, Jyrki

Dear Jyrki,

I was able to reproduce your "-mabi=ilp32 support" issue. We recognize this as a issue with the toolchain release and we will investigate.

In the mean time please file a bug on https://bugs.linaro.org/ regarding issue #2 (-mabi=ilp32 support) so it can be tracked externally.

kind regards
