NIOS II Command Shell "make" issue with WSL

Hi @FPGAStormRaider,

Thank you for posting in Intel community forum and hope this message find you well.
Would suggest to try on the following workaround to generate the make steps:
1) I believe you are able to use the Nios II SBT eclipse to build and generate the BSP
2) Delete the Makefiles from the apps project directory. (copy somewhere as backup if changes are done previously)
3) Open Nios ii command sheel and cd to the apps project directory
4) Execute the following command in shell "xport WSLENV=PATH/1:${WSLENV}" & "./create_this_app" (might be some error but do verify new Makefile are generated)
5) Edit the resulting new Makefile in the apps project directory as follows:
a) Approx line 326,change -“APP_LDFLAGS += -msys-lib=$(call adjust-path-mixed,$(SYS_LIB))” to “APP_LDFLAGS += -msys-lib=$(SYS_LIB)”
b) Approx line,132change –“BUILD_PRE_PROCESS :=” to “BUILD_PRE_PROCESS := touch $(ELF).srec”

Please do run a 'uname -r' in ubuntu and let us know what is return.
Do let us know if that steps helps.

Best Wishes
BB
