mdadm 2.0 and 2.1 compile error

mdadm 2.0 and 2.1 compile error

[Norman Schmidt]

Hello!

I am trying to compile the mdadm source (from 
http://www.cse.unsw.edu.au/~neilb/source/mdadm/mdadm-2.x.tgz) under SuSE 
9.3 (64bit) on an opteron system.

On "make" I get the following fatal error for both 2.0 and 2.1:

bitmap.c: In function `bitmap_fd_read':
bitmap.c:130: warning: int format, different type arg (arg 3)
make: *** [bitmap.o] Error 1

What is the problem and how can I fix it?

Tia, Norman Schmidt.

mdadm 2.0 and 2.1 compile error

[Stephan van Hienen]

I am trying to compile mdadm 2.x (currently running version 1.12)

On "make" I get the following fatal error for both 2.0 and 2.1:

In file included from super0.c:31:
/usr/include/asm/byteorder.h:6:2: #warning using private kernel header; 
include <endian.h> instead!
make: *** [super0.o] Error 1

any idea ?

system is tao 1.0 (based on rhel3) with 2.6.13.2 kernel source (also tried 
2.6.11.7 source)

This means your distro is crazy.  endian.h does not contain the
defines that I need from byteorder.h.
Just remove the '-Werror' from the Makefile and try again.

That resolved it for me.  Distro is RHEL 4 in my testing.

-Werror is (arguably) great for local debugging, but it's a bad idea
to use for distributed software.
