Issue in Nios Eclipse : elf not generated - Issue in Nios Eclipse : elf not generated Issue in Nios Eclipse : elf not generated Computer configuration : Windows 10 Quartus version 19.1 standard Nios Eclipse : Mars 9.2 I have install Quartus without issues but when I have want to execute NIOS Eclipse some issues occurs. I have done all the checklist done at : How do I install the Windows* Subsystem for Linux* (WSL) on Windows? https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2019/how-do-i-install-the-windows--subsystem-for-linux---wsl--on-wind.html and also the procedure to install unbuntu 18.04LTS for WSL https://docs.microsoft.com/en-us/windows/wsl/install-win10 After I open Nios Eclipse , I'm able to create a project and the Nios applicationand BSD from template but when I complie the project the elf file is not generate and the message : ***make[Makefile1011: xx.elf]error 1 appears This is the information done by the console when I made the Build 11:34:29 **** Incremental Build of configuration Nios II for project daniel_2 **** wsl make all wslpath: hal_bsp: No such file or directory Info: Building /mnt/c/Quartus_Project/test/C10LP_NiosII_hello_world_project1/software/daniel_2_bsp/ make --no-print-directory -C /mnt/c/Quartus_Project/test/C10LP_NiosII_hello_world_project1/software/daniel_2_bsp/ [BSP build complete] Info: Linking daniel_2.elf nios2-elf-g++.exe -T'C:/Quartus_Project/test/C10LP_NiosII_hello_world_project1/software/daniel_2_bsp/linker.x' -msys-crt0='C:/Quartus_Project/test/C10LP_NiosII_hello_world_project1/software/daniel_2_bsp/obj/HAL/src/crt0.o' -msys-lib= -LC:/Quartus_Project/test/C10LP_NiosII_hello_world_project1/software/daniel_2_bsp -msmallc -Wl,-Map=daniel_2.map -Os -g -Wall -mno-hw-div -mno-hw-mul -mno-hw-mulx -pg -mgpopt=global -o daniel_2.elf obj/default/hello_world_small.o -lm -msys-lib=m nios2-elf-g++.exe: error: missing argument to '-msys-lib=' make: *** [Makefile:1011: daniel_2.elf] Error 1 11:34:30 Build Finished (took 1s.10ms) Can yo help me to solve this issues Thanks in advance Replies: Re: Issue in Nios Eclipse : elf not generated hi tweeklab in your output. I'm not sure why the Makefile tries to translate this string. To fix it, open your project Makefile and look for a line like this: APP_LDFLAGS += -msys-lib=$(call adjust-path-mixed,$(SYS_LIB)) For me it's around line 326, but is probably a bit different for you. Change it to: APP_LDFLAGS += -msys-lib=hal_bsp After this your project will build again. whatever solution provided its working ,i am able to generate .elf file ,but should we do for every new application file generation ?is their any fixed solution for this issue ,thanks for posting solution Replies: Re: Issue in Nios Eclipse : elf not generated Hi, Magali Can we close the case if you have no question ? Thanks. Eric Replies: Re: Issue in Nios Eclipse : elf not generated Hi, Magali Have you tried below workaround ? 1. Starting with Nios II EDS in Intel Quartus Prime Pro Edition version 19.2 and Intel Quartus Prime Standard Edition version 19.1, the Cygwin component in the Windows version of Nios II EDS has been removed and replaced with WSL. For installation instructions, refer to the Installing Windows Subsystem for Linux (WSL) on the Windows section in the Nios II Software Developer Handbook. For machines installed with McAfee Endpoint Security, the minimum requirement is Windows 10 Version 1809 (OS build 17763). If you are using a network drive for the Nios II EDS, the minimum requirement is Windows 10 Version 1903 (OS build 18362). You may refer to page 17 of https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/n2sw_nii5v2gen2.pdf 2. You may try to update the WSL 2 software by following below: https://docs.microsoft.com/en-us/windows/wsl/install-win10#:~:text=Update%20to%20WSL%202,-To%20update%20to&text=Check%20your%20Windows%20version%20by,Get%20Windows%20Update%20Assistant. 3. https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2019/why-does-the-nios--ii-not-installed-after-full-installation-of-t.html https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/embedded/2019/e--unable-to-locate-package-doc2unix.html https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/embedded/2019/error--failed-to-execute--wsl---create-this-bsp-no-make.html Thanks. Eric Replies: Re: Issue in Nios Eclipse : elf not generated thanks a lot for your help It's works now. Replies: Re: Issue in Nios Eclipse : elf not generated I just ran into this issue and found your post while googling for a solution. For me a perfectly functional project just stopped working. The root cause is that the wslpath program (used to translate between Linux and Windows paths in WSL) seems to have changed. I took OS updates this morning so that is the only explanation I have. Your Makefile is trying to basically do this: wslpath -m hal_bsp I'm guessing this just used to return simply "hal_bsp" because other ways of calling wslpath still seem to return this string. Now it is the reason you see: " wslpath: hal_bsp: No such file or directory" in your output. I'm not sure why the Makefile tries to translate this string. To fix it, open your project Makefile and look for a line like this: APP_LDFLAGS += -msys-lib=$(call adjust-path-mixed,$(SYS_LIB)) For me it's around line 326, but is probably a bit different for you. Change it to: APP_LDFLAGS += -msys-lib=hal_bsp After this your project will build again.
