I had a go at what you suggested but this had no effect, it came up with exactly the same error. From what i can see from the error, it is looking in the linux/ directory in the libmad/ source directory, not in /usr/src/linux. I tried doing what you suggested but making the link in the libmad directory rather than in /usr/src, so now i have a link
mad-0.13.0b/libmad/linux -> /usr/local/arm/gnu/release/arm-linux/include.
Now it finds errno.h ok but generates different errors
decoder.c: In function 'mad_decoder_finish': decoder.c:91 'EINTR' undeclared (first use in this function) decoder.c:91 (Each undeclared identifier is reported only once for each function it apears in.) decoder.c In function'send_io': decoder.c:120 'EINTR' undeclared (first use in this function) decoder.c In function'recieve_io': decoder.c:142 'EINTR' undeclared (first use in this function) decoder.c:145 'EAGAIN' undeclared (first use in this function) make: *** [decoder.lo] error 1
I am wondering are there some required files that are needed for cross compiling that i have not installed?
Thanks

Thanks for the help!
I had a go at doing the CC=... and RANLIB=... on the same line as the ./configure as suggested. This seems to have the dedsired effect, the configure script reports that gcc is a cross compiler and when i look at the Makefile all the paths are pointing to the right place. i.e. the cross compiler i installed.
Now when i come to make, it runs for a bit but then reports the error :
/usr/local/arm/gnu/release/lib/gcc-lib/arm-linux/2.95.3/../../../../arm-linux/include/bits/errno.h:25: linux/errno.h: No such file or directory
Why is the file bits/errno.h looking for another file of the same name? Is this meant to be an ARM specific errno.h? I did a search for this file and came up with loads :
/usr/include/asm/errno.h /usr/include/linux/errno.h /usr/include/bits/errno.h /usr/include/errno.h /usr/include/sys/errno.h /usr/local/arm/gnu/release/arm-linux/include/bits/errno.h /usr/local/arm/gnu/release/arm-linux/include/errno.h /usr/local/arm/gnu/release/arm-linux/include/sys/errno.h /usr/src/linux-2.4.3/include/asm-i386/errno.h /usr/src/linux-2.4.3/include/linux/errno.h
Which one is it looking for and how do i tell it to use that specific one?

Hi, I am wanting to compile libmad for ARM. I have installed :
arm-linux-binutils-2.11-1 arm-linux-gcc-2.95-1 arm-linux-glibc-2.1.3-1
To cross compile i do :
export CC=/usr/local/arm/gnu/release/bin/arm-linux-gcc export RANLIB=/usr/local/arm/gnu/release/bin/arm-linux-ranlib export LD=/usr/local/arm/gnu/release/bin/arm-linux-ld export NM=/usr/local/arm/gnu/release/bin/arm-linux-nm
./configure --host=arm-linux --enable-speed --enable-fpm=arm
The configure script completes fine but in the messages it prints i
see
the lines :
checking weather the C compiler (gcc ) is a cross-compiler ... no . . cheching for ld used by GCC... (cached) /usr/bin/ld
so it is not using the cross compiler that i installed. I read in another mail that i may have to configure manually. Is this the case
or
is there somthing i am missing out?
Thanks in advance.
I fixed it!!! I think.
I just added "# include <errno.h>" to decoder.c and it compiled fine using "CC=<path>/arm-linux-gcc RANSLIB=<path>/arm-linux-ranlib ./configure <options>" and then "make".
I think the errno.h that it was looking for was the one in /usr/src/linux-2.4.3/include/asm-i386/errno.h This one had all the defines for 'EINTR' etc.
Now to compile minimad.c!

In general error numbers are platform dependent, so including an x86 header file probably isn't the safest thing to do... :-)
It looks like your problems come from a messed up toolchain - you may be better off getting hold of a pre-built version that is know to work.
The gcc v2.95.3 from
ftp://ftp.arm.linux.org.uk/pub/armlinux/toolchain/
works for me.
mad-0.14.2b builds without problem after running configure with the following options:
CC="/usr/local/arm/2.95.3/bin/arm-linux-gcc" ./configure --enable-speed --disable-debugging --enable-fpm=arm --disable-nls --disable-mmap --host=arm-linux
(Note that other options probably work fine as well, but the above should produce something fairly optimal for ARM).

Thanks for the advice. I downloaded that compiler and followed the installation instructions. I tried running configure with your options but it complains that the C compiler cannot create executables. I is definitley looking for the new compiler and not the old one (which i have uninstalled).
I tried running the compiler manually form the command line and it does seem to work so what could the problem be?

Try running "make distclean" before configure (or untar yourself a fresh copy of mad in a new directory and try configuring that).
Double check that CC="..." really does point to the compiler and doesn't have a typo. (If you have added /usr/local/arm/2.95.3/bin to your path, you can simply use CC="arm-linux-gcc").
Have a look at the 'config.log' file which will give more details of what actually went wrong.

Yeah, i had that problem at first. It was looking for the wrong complier even though i had specified the path to the new one. Once i had done make distclean it looked for the correct compiler.
I have made a hello world program just to test it. I did ./arm-linux-gcc main.c and it gave :
/usr/local/arm/2.95.3/arm-linux/lib/libc.so.6: file not recognised: File truncated collect2: ld returned 1 exit status
Could file truncated be a bad download? Also, where arm-linux-gcc is about 181k, arm-linux-ld is zero size. What's going on here?

My copy of arm-linux-ld is approx 1.3 MB.
ftp://ftp.arm.linux.org.uk/pub/armlinux/toolchain/
doesn't seem to give checksums for the toolchain archives, but the copy of cross-2.95.3.tar.bz2 that I have is 36273634 bytes long, with an md5 hash of

I have downloade the toolchain agian and extracted it. 2.95.3/bin/arm-linux-ld is still zero size. But, 2.95.3/arm-linux/bin/ld is about 1.3M ad you said yours was. Are these the binaries i am supposed to be using, the ones in 2.953/arm-linux/bin rather than 2.95.3/bin?
