nios2 eclipse 19.4 - Compilation error: nios2-elf-cc: command not found

Hi, Tamir

Would you mind to forward your design to me for replication ?

May I know which Linux you are using ? which wsl you installed etc. ?

Thanks.

Eric

Hi Tamir,

Can you try to find a new computer to install or remove NiosII EDS and reinstall it? May you try newer 20.1 or 20.2.

You can try below manually.

1. install WSL for windows

i. https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/n2sw_nii5v2gen2.pdf (chapter 2.1)

Note: Windows 10 build version 16215.0 or higher is the recommended operating system version.

ii. After installation has successfully completed, launch Ubuntu 18.04.

iii. Install additional distro packages required for Nios II EDS using the following commands:

a. sudo apt install wsl

b. sudo apt install doc2unix

c. sudo apt install make

before"sudo apt install wsl"

run:

sudo apt-get update

2. install nios2 eclipse folder

Hi, Tamir

Is your problem resolved ?

Eric

Hi, Tamir

May I know are you installing wsl 1 or 2 ?

Eric

Hi, Tamir

Would you mind to install QPro 20.2 ?

Thanks.

Hi, Tamir

Can you try below workarounds.

#1

Open a NIOS2 command shell

try and make an NIOS2 application

You get the following error: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory

To resolve this you need run the following command prior to calling make, "export WSLENV=PATH/l:${WSLENV}"

#2

With the above fix you can compile all the files but the link fails:

nios2-elf-g++.exe: error: missing argument to '-msys-lib='

To resolve this you need to modify the application Makefile and change the following line:

APP_LDFLAGS += -msys-lib=$(call adjust-path-mixed,$(SYS_LIB)) to APP_LDFLAGS += -msys-lib=$(SYS_LIB)

In adjust-path-mixed should not be used in this case as SYS_LIB is a name of a library not a PATH to the library

#3

The final problem is that from eclipse debugging fails with the following error:

wslpath: /mnt/f/main_clean/Software/omni_ip/projects/wfm_ss/example/wfm/wfm_app/wfm.elf.srec: No such file or directory

wslpath: /mnt/f/main_clean/Software/omni_ip/projects/wfm_ss/example/wfm/wfm_app/wfm.elf.srec: No such file or directory

Using cable "USB-BlasterII [USB-1]", device 1, instance 0x01

Pausing target processor: OK

Restarting target processor

rm: cannot remove '/mnt/f/main_clean/Software/omni_ip/projects/wfm_ss/example/wfm/wfm_app/wfm.elf.srec': No such file or directory

To resolve this problem the Application Makefile must be modified again with the following change:

BUILD_PRE_PROCESS := to BUILD_PRE_PROCESS := touch $(ELF).srec

Thanks.
