nios2-elf-gcc.exe: error: CreateProcess: No such file or directory - nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Hi, Windows 10 Pro 2004 19041.450 Quartus Prime Pro 19.4, build 64 All Intel and Nios SW is on a local drive. I get this error in the NiosII shell: "nios2-elf-gcc.exe: error: CreateProcess: No such file or directory" Do you have any hints or path available? Regards. Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory As a solution to the issue nios2-elf-gcc.exe: fatal error: cannot execute 'cc1': CreateProcess: No such file or directory we have found useful what follows. Before running make.exe on the generated Makefile, add this to your bash script: export WSLENV=PATH/l:${WSLENV} sed -i 's/\(adjust-path[-mixed]*\) = .*/\1 = $1/' Makefile WSLEN fixes missing pathnames, while sed basically removes the effect of adjust-path. This is an issue introduced by a Windows update but I still believe Intel should provide a fix or patch for it. We wasted several days on it. Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Additional details to workarounds/corrections There are problems trying to create a new app or create a new format Makefile for an older app. I had to manually create a wsl env for SOPC_KIT_NIOS2. In wsl: export SOPC_KIT_NIOS2=/mnt/e/intelFPGA/20.1/nios2eds Then for any create-this-app change "Microsoft" to "microsoft" Then edit the resulting created Makefile to change "Microsoft" to "microsoft" and change APP_LDFLAGS += -msys-lib=$(call adjust-path-mixed,$(SYS_LIB)) to APP_LDFLAGS += -msys-lib=hal_bsp additional: change Makefile to BUILD_PRE_PROCESS := touch $(ELF).srec (per this post ) modify nios2-download and nios2-configure-sof scripts to use lower-case 'm' Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory @Eliath_G_Intel , My workaround is a combination of things. I manually added a couple of sdk paths to my windows environment Path. (E:\intelFPGA\20.1\nios2eds\bin;E:\intelFPGA\20.1\nios2eds\bin\gnu\H-x86_64-mingw32\bin) I rebooted wsl (by restarting LxssManager service) to get the updated $PATH. I edited the Makefile to change "Microsoft" to "microsoft" Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Good morning, and thanks for the suggestion I will give it a try. Regards Simon Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory As a temporary solution, I just found that it is working with normal windows command prompt instead of WSL. So, I just opened windows command prompt with "cmd" command. Then, set the path (that may vary on your system) as below. set PATH=C:\intelFPGA_pro\20.1\nios2eds\bin\gnu\ H-x86_64-mingw32 \bin;%PATH% And, built my library using "nios2-elf-gcc.exe" commands. Only thing, unix-style shell commands won't work. I just replaced "rm -f" with "del" in my makefile. ---- Hope Intel will provide the proper solution to this very soon!! Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Hi I have exactly the same error. Is there any resolution to this? Regards Simon Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory I have the same or similar problem. My wsl (v2) is up to date as is my Win10 version (2004). It appears the problem is paths. The $PATH in nios command shell contains /mnt/e/intelFPGA/20.1/nios2eds/bin/gnu/ H-i686-pc-linux-gnu /bin That path doesn't exist in my installation: however this one does /mnt/e/intelFPGA/20.1/nios2eds/bin/gnu/ H-x86_64-mingw32 /bin Neither of those paths (or their windows equivalents) is in my windows path environment or subsequently in my wsl $PATH. Should the 20.1 quartus full install have added a path for nios2eds, and if so which? Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Hello Intel support team, Is there any solution for this error? Me too getting the same error after updating the Windows. I tried to reinstall everything. But, getting same error. Please let me know the solution since it is very urgent. Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Hi Eliath, I tried what you suggest and I got the same error. We have had WSL correctly installed from the very beginning. Please read my messages above. The issue started after the latest Windows 10 updates. Regards Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Hi Marco! Thanks for reaching us, Please follow the next steps: Install WSL Open the terminal run $ nios2_command_shell.sh run the tests you need to make , at this point it should work properly. As resume, you need to have WSL correctly installed. Please try those steps and let me know the results. Best regards, -Eliath Guzman Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Another bit of info. We had a second PC where our original script was working (i.e. nios2-elf-gcc.exe was not failing). Today we updated this PC to Windows 19041.450 and after that we get the same error message also on this second PC! Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory Easy way to replicate: 1.- create an empty C source file (e.g. a.c) 2.- execute gcc from the nios shell nios2-elf-gcc.exe -c a.c and you'll get the error. Replies: Re: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory I installed now 20.2 and it gives the same error but a bit more info: ...
