about compilers

I think your problem is that you're trying to build this with an x86 compiler (i.e. one targetted at producing PC instructions) which you don't have installed properly, the line

checking host system type...i686-pc-cygwin

implies this

Hi Huck,

> I think your problem is that you're trying to build this with an x86 compiler

When you cross-compile and use a vanilla GNU "configure" script, you will normally need

to configure with the --host option:

$ ./configure --host=nios2-elf

But this wil likely cause an error during configuration ... as "nios2" is rarely supported.

See the following thread for some ideas:

Hi Scott,thank you for your help,but I use the nios1 not the nios2!!

So if there is an --host option :./configure --host=nios-elf

Now I'm trying to install the "gcc compiler "on my pc,an I right ?

Thank you!

If you're using Nios/Classic Nios, you may have better luck finding what you want here (http://sourceforge.net/projects/cdk4nios/).

Hi Huck,

Yes, this is the option you will need. The concept is the same: you need to add a "nios" entry to the

config.sub script. This is what configure will use when is checks for all of those magic options ;-)

Basically, it will attempt to use nios-elf-xxx when performing its tests. E.g. nios-elf-gcc, nios-elf-ld, etc.

Once the configure script knows what "basic machine" it's using (and therefore what prefix to use for

the binutils/gcc excutables), it will need to know the correct include and library paths. This is the

reason you need to set CPPFLAGS and LDFLAGS in your environment. For other architectures, such

as powerpc-linux, you normally don't need to do this, but for nios, you most likely will.

Since you're using Nios-32 (rather than Nios II), you will probably do well to use the cdk4nios as

Brendan suggested ... or bite the bullet and upgrade to Nios II ;-)

Good Luck,

Hello all my friends:

Thank you for all your helps!~

CDK4NIOS stands for Cross Development Kit for Altera's soft core processor NIOS and should you support with a comprehensive Assembler and C/C++ development environment under Linux.

But now I'm using the windows operating system!!!

Can I use the CDK4NIOS all the same?

hi Scott!

>Yes, this is the option you will need. The concept is the same: you need to >add a "nios" entry to the config.sub script.

This is the text from the config.sub file:

amigaos | amigados)

basic_machine=m68k-cbm

os=-amigaos

;;

amigaunix | amix)

basic_machine=m68k-cbm

os=-sysv4

;;

apollo68)

basic_machine=m68k-apollo

os=-sysv

The first question is:I dare not to edit the file easily!

How can I made the configure script knows what "basic machine" it's using ?

>reason you need to set CPPFLAGS and LDFLAGS in your environment

Excuse me to ask you:how can I do this?

Hi Huke,

> How can I made the configure script knows what "basic machine" it's using ?

There are three basic things configure needs to know:

1. What cross-tools (e.g.: nios-elf, rather than powerpc-eabi, or arm-thumb-elf, etc)

2. What is the include path for .h files.

3. What is the library path (or libc, etc).

To modify the configuration scripts, you may have to do some hard work ... it's not

always as straight-forward as the the libosip source tree. Basically, you must read

and understand how the configure scripts work, then modify the scripts to support

your target environment.

Please see the link in my earlier post.

I'm a bit confused here: You want your code to run on a Nios-32 processor that

is running uClinux, correct?

If this is the case, you surely have uClinux running, no? ... and this means you

have a development environment (with headers, libraries, etc) under windows.

Hi scott!

>Add an entry for nios2 for the basic_machine variable. All you need is "nios2" in there ;-)

The origin text is

amigaunix | amix)

basic_machine=m68k-cbm

os=-sysv4

then I edit it to:

amigaunix | amix)

basic_machine=nios

os=-sysv4

Am I right??

I do not have any development environment under windows in fact,I only have the sopc builder shell!!

Hi scott!

It seems I must install a uClinux operating system on my windows XP!

The nios1 is not running uClinux on itself! I saw the document and they do not said any thing about uClinux. But I get the package from a linux organization,so I need to install the uClinux on my windows XP! Am I right?

Thank you very much!
