Table 5–1. nios2-c2h-generate-makefile Command Line Arguments (Part 1 of 2)
Argument Name
The Nios II software build tools support the Nios II C2H Compiler on the
command line with the nios2-c2h-generate-makefile command. This
command creates a C2H makefile fragment that specifies all accelerators
and accelerator options for an application.

C2H Compiler projects created on the command line cannot be
imported into the Nios II Software Build Tools for Eclipse.
Altera recommends creating new C2H accelerators with the
Nios II IDE.
--sopcinfo=<SOPC Builder System File> [OPTIONS]
