Why does nios2-elf-gcc utility not understand the "cygwin path name format" on Windows with Cygwin? - Why does nios2-elf-gcc utility not understand the "cygwin path name format" on Windows with Cygwin? Description This is a known issue with Nios® II EDS software versions 10.0,10.1,11.0 and 11.1 using GCC 4 tool chain. Here are the example of error messages: nios2-elf-gcc.exe: /cygdrive/d/test/hello.c: No such file or directory nios2-elf-gcc.exe: no input files This will be fixed in future version of Quartus II software. Resolution (a) Use GCC 3 tool chain if available In the Windows operating system, on the Start menu, point to Programs -> Altera -> Nios II EDS <version> -> Legacy Nios II Tools and click Nios II <version> Command Shell [gcc3] OR (b) Use other path name formats like Quoted Windows, Escaped Windows, or Mixed. For example, the hello.c file resides in D:\testDir directory // Quoted Windows nios2-elf-gcc "D:\testDir\hello.c" // Escaped Windows nios2-elf-gcc D:\\testDir\\hello.c // Mixed nios2-elf-gcc D:/testDir/hello.c Custom Fields values: ['novalue'] Troubleshooting novalue False ['novalue'] ['novalue'] novalue novalue ['Programmable Logic Devices'] ['novalue'] ['novalue'] ['novalue']
