How to compile linux application under Nios II IDE

[Altera_Forum]

Could anybody help me how to compile programs from Nios forum Linux1.4 distribution for Nios2 under Elipse IDE Windows environment.  

I don't have any problems with compilation of kernel, file system. I created new Linux application project, Rules.mak and Settings.mak were generated. I want to compile programs from linux1.4/examples/software/linux/apps/e2fsprogs/misc directory. What should I do ... When I compile according to makefile from linux1.4/examples/software/linux/apps/e2fsprogs/misc, there are a lot of errors, bad paths, etc.  The linux1.4 files are installed in d:\altera\kits\nios2\bin\eclipse\plugins directory. Could anybody sent me a makefiles for compilation of these programs?  Best Regards Xenix

Di you try looking at the wiki ? I have no idea how one would do it, but I assume you are running Microtronix linux developed under windows. 

 There should be a Reference guide provided by them.  I developed my nios2 uclinux apps under windows via colinux.    --- Quote Start ---  originally posted by xenix@Nov 21 2006, 07:13 AM could anybody help me how to compile programs from nios forum linux1.4 distribution for nios2 under elipse ide windows environment.  i don&#39;t have any problems with compilation of kernel, file system. i created new linux application project, rules.mak and settings.mak were generated. i want to compile programs from linux1.4/examples/software/linux/apps/e2fsprogs/misc directory. what should i do ... when i compile according to makefile from linux1.4/examples/software/linux/apps/e2fsprogs/misc, there  are a lot of errors, bad paths, etc.  the linux1.4 files are installed in d:\altera\kits\nios2\bin\eclipse\plugins directory. could anybody sent me a makefiles for compilation of these programs?  best regards xenix <div align='right'><{post_snapback}> (index.php?act=findpost&pid=19557)  --- quote end ---    --- Quote End ---

Then i don&#39;t know. I usually just create my own make files as i write programs.

Hey man, 

 I know how you feel. I was in that exact same position half a year ago or so...took me almost a week to stabalize how I write the makefiles for NIOS uClinux app. Anyway, here it is, the complete makefile that would work for any NIOS Linux app ported from Microtronix. Just study it, and ask questions if you have any. It might be helpful if you have the old Rules.mak to compare the changes I made.   There are two files, Makefile and Rules.mak  First, Rules.mak ########################################################################### Variables and Rules for building Nios II Linux applications# # This file is a "template" that is copied over from the Nios II Linux# Application plug-in.  This file should be included within your top-level# Makefile. # This turns on various levels of hardware multiply support# Set the following option to none, mul, or mulx#  none := no hardware multiplication support at all#  mul := supports use of the mul assembler instruction#  mulx := supports use of the mul and mulx assembler instruction ifeq "$(HW_MUL_SUPPORT)" ""     HW_MUL_SUPPORT := mulx endif # # Warn users if external variables have not yet been defined.# ifeq "$(origin UTILSDIR)" "undefined" $(warning The location of the utiltiies directory is undefined) endif ifeq "$(origin LIBCDIR)" "undefined" $(warning The location of uClibc is undefined) endif # # Path + Name of necessary executables# EXECSUFFIX := .exe CROSS       := nios2-elf- CC          := $(CROSS)gcc CPP        := $(CROSS)g++ AR          := $(CROSS)ar LD          := $(CROSS)ld NM          := $(CROSS)nm RANLIB      := $(CROSS)ranlib STRIPTOOL   := $(CROSS)strip ELF2FLT     := $(UTILSDIR)/bin/elf2flt # # Location of important files# CRT0  := $(LIBCDIR)/lib/crt0.o LIBC  := $(LIBCDIR)/lib/libc.a LIBM      := $(LIBCDIR)/lib/libm.a LIBGCC  := $(shell $(CC) -print-file-name=libgcc.a) LIBGCCDIR   := $(dir $(LIBGCC)) LINKSCRIPT  := $(UTILSDIR)/scripts/elf2flt.ld # # Various flags, modifications are not recommended and not necessarily#  supported.# #  DEPFLAGS:#   -MM : ignore system includes, #    -M : include system includes in the dependency# WARNING_FLAGS := -Wall # basic C flags to pass to the compiler CFLAGS += -nostdinc -D__linux__ # if DEBUG is turned on, then turn off optimizations and turn on symbol# generation, else turn on level 2 optimizations ifeq '$(DEBUG)' '1'     CFLAGS += -O0 -g else     CFLAGS += -O2 endif # pass any additional include directories to the compiler while building the# application CFLAGS += -I$(LIBCDIR)/include -I$(LIBGCCDIR)include # Temporary workaround for nios2-elf-gcc bug# First noticed in v3.4.1 (Altera Nios II 1.1 b131)# To be removed at a later date when bug is resolved.
