NIOS SBT not generating elf

Hi, Bryant

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.
