Problem with cross-compiler compiling under Cygwin

[Sham]

Hello, I have an problem, obviously. Problem is when i try to make cross-compiler for cygwin i get message like this:

Code: Select all

Cannot find fixincl
Makefile:4213: recipe for target `stmp-fixinc' failed
make[1]: *** [stmp-fixinc] Error 1
make[1]: Leaving directory `/home/Jani/cross/source/build-gcc/gcc'
Makefile:3908: recipe for target `all-gcc' failed
make: *** [all-gcc] Error 2

and this is while i am trying to do "make all-gcc" if anyone is wondering. So does anyone have any idea what i should be doing so i can get around this error (Telling to go with linux is not answer here, because i want to use my more powerful computer for OSdeving) so, please help me and everyone who "will" answer this, Thank you!

Hi,

Hopefully there isn't a bug in the GCC cross-compiler article. I wrote the latest revision, but as I don't use Windows, I was unable to test it with Cygwin. I've heard of people succeeding since then, I think though. That said, my guess is that you are doing someone wrong. Are you following the tutorial's instructions to the letter? Please read it more carefully. Note that you cannot use the binutils and gcc source code that cygwin uses, you should use the official binutils and gcc source code.

The problem seems to be related to fixincludes, which is a script that GCC uses to forcefully "fix" headers on its target system (such that they are more standards compliant). You are building a fully freestanding compiler (i586-elf-gcc) and it has no system root that contains headers for your OS (it's not needed, yet), so fixincludes shouldn't be run. This makes me wonder if you have accidentally used the wrong configure line. Could you post the ./configure line you used for GCC with variables expanded? You remembered to pass --without-headers right? Additionally, please attach more output from Make, there may be something further up that you missed. Please also double-check that you have installed all the dependencies for GCC.

If you deviated somehow from the tutorial, please tell us immediately.

Edit:

cross-compiler for cygwin

Do you mean "cross-compiler inside the cygwin environment" - or are you trying to build a cygwin compiler that produces executables for cygwin? If you are doing the latter, this means you are not building a cross-compiler and things will explode much like this.

I'm not quite sure what you mean here. TBH, you would find a lot more help available if you did use Linux, as that is what so many other people use. And it would probably make better use of your powerful computer than Cygwin does.

But each to their own. (It's just that it seems you may be labouring under a misapprehension.) If you want to use Cygwin that's fine but just be aware that support will not be as good as under Linux.

@sortie thank you it works on cygwin.

The OP is definitely making a mistake.

@skorpion

try these instructions mit tools with combination of the SortieWikiSample

It should work. Good Luck....

[sortie]

Jvac: Uh. You are not using a cross-compiler! Try use i586-elf-gcc and friends instead.

You were saying?

Please explain

[Combuster]

You didn't demonstrate anything.

I still don't see explicit invocations of 1586-elf-gcc - or even i386-jos-elf-gcc.

(Therefore it didn't happen... )

[Jvac]

@Combuster

i386-jos-elf-gcc example, believe me it works

[Jvac]

In fact just run into a problem with my ARM i686-pc cross using cygwin.

Code: Select all

myPC ~ myOS/Configure/Libraries/GeneralPurpose/arm
$ make

According to the 3.17.2 ARM Options on the gcc website these are ok.

here are the ARMOPTS from my make file.

Code: Select all

ARMOPTS = -msoft-float -mpoke-function-name -mapcs -march=armv5te -mfpu=fpa -fnon-call-exceptions -fasynchronous-unwind-tables

Any idea guys what is causing this?

[xenos]

Are you kidding? You are giving ARM options to an i686-pc-linux-gnu targeted compiler? i686? Seriously?

i386-jos-elf-gcc example

cc (...)
cc (...)
cc (...)

It says "cc", not "i386-jos-elf-gcc". i.e. the same as with XenOS: Learn to invoke the correct compiler.

[Owen]

It says "+ cc", which tells me that the standard makefile output was suppressed and "pretty" output used instead. I.E. the rule looks like

Code: Select all

%.o: %.c
    @echo +cc $@
    @my-gcc -c -o $@ $< $(CFLAGS)

[Combuster]

Or it looks like... a better implementation?

Code: Select all

%.o: %.c
        @echo + $(CC) $@
        @$(CC) $(CFLAGS)  $< -o $@

After all, the only thing he demonstrated is an attempt at adding the crosscompiler to the path and being unable to read. (both error messages and my earlier point that he didn't prove anything)

Guess you are right. Back to the lab to re-study compilers.

Thanks for the explanation guys.

Ill be back.......
