Re: unable to build glibc-2.2.5 with gcc-3.1 for ARM

What I have as directory structure for cross compilation is this :

suppose I'm cross-compiling for a 'arm-linux' target with prefix=/usr/local/arm-linux/

headers for arm-linux should go into '/usr/local/arm-linux/arm-linux/include'
(note the 'arm-linux/arm-linux' part -> $(DESTINATION)/$(TARGET)/include)


binutils and gcc should be configured with :
   --prefix=/usr/local/arm-linux --target=arm-linux

arm-linux specific libraries will be put in :
/usr/local/arm-linux/arm-linux/lib (!!)

glibc should be configured with
   --prefix=/usr/local/arm-linux/arm-linux

because the libraries created are specific for arm-linux

with this structure,
  /usr/local/arm-linux/lib should only contain 'host' (ex. i386) specific libraries,
and
  /usr/local/arm-linux/arm-linux/lib should contain 'target' (ex. arm-linux) libraries.
