Cross GCC [message #1767997]

I'm using the De0-SoC-nano board from Altera and I would like to compile a simple Hello World on the Nios2 Eclipse and then scp it to the board and run it. However, whenever I build a project the executable made is a .exe and only runs on windows and doesn't have the proper binaries to run on the de0 Linux. What needs to be done to ensure I'm making an executable that will run. I can execute their "my_first_hps" on the board, but my own programs won't work. I've tried editing PATH and the tool chain is on Cross GCC GNU Builder.

It sounds like you are using the wrong gcc. Please refer to Intel (Altera is now part of Intel) for help on how to create a Nios 2 project that uses Nios 2's gcc instead of default gcc. (A hint is that mingw/cygwin gcc will almost certainly be the wrong ones)

Right, I discovered the mingw being wrong later that afternoon. I've been compiling with the "nios2-elf-gcc" and it is making an executable that appears to be in Linux format; however, the problem is the binaries can't be executed when I try to run it on the board.. Is this a problem between 32 and 64 bit, and if so which nios2 compiler compiles into an executable for the 32 bit armv71?

Thanks,
Ryan

Hi Ryan,

None of the Nios compilers will make arm executables. The Nios compilers will make Nios executables. See http://www.alteraforum.com/forum/showthread.php?t=48797
