Re: i386-elf/coff cross build

["b gonzales" <bgonzales at uswest dot net>]

I encountered this problem before.

 

What I did was I copied /bin/ar into one of the bin directory of the cross compiler.

 

Try examining the make file. There is a line there that references the ar program.

 

I'm sorry that I cannot give the details because  I have no notes about it.

 

Hope this helps.

Subject: i386-elf/coff cross build

Hi all,

 

I am in the process of building cross compiler tools for intel 386 embedded target with a custom RTOS.  Has anybody succeded in installing the i[3456]-elf or i[3456]-coff gcc cross compilers with linux or windows(cygwin) host. I'm seeing lot of failure stories in building i386 cross tools in the mailing list

 

I am using gcc-2.95.2 with newlib-1.8.2.  I am able to build bin utils for i386-coff successfully. But when i try to install gcc i am getting the follwoing errors (I tried with both cygwin and linux host but the result is same).  Any help in solving the problem is very much appreciated.

I was successfull in creating powerpc-eabi and arm-coff for both the host and obviously i follow the same procedure for building i386-coff also.

 

I have got one more question. Does anybody know, like.. what are the issues in using gcc with a custom developed RTOS (not RTEMS or eCos) and its own C library routines for am embedded target.

 

Thanx in anticipation
