Version 1.1.1. From other postings on u-boot it
appears that the issue is soft float support...

I will try this. Hopefully there are build
instructions for the tools.

*** Copy of an email sent to Dan Kegel regarding this
issue. The U-Boot compilation errors are below.

1. This will not compile Linux 2.6 because the
binutils are too old. Need support for .incbin.

BINUTILS_DIR=binutils-2.11.2
BINUTILS_URL=ftp://ftp.gnu.org/pub/gnu/binutils
GCC_DIR=gcc-2.95.3
GLIBC_DIR=glibc-2.1.3
LINUX_DIR=linux-2.4.21
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.1.3
GLIBCCRYPT_FILENAME=glibc-crypt-2.1

2. Same problem as #1
BINUTILS_DIR=binutils-2.11.2
BINUTILS_URL=ftp://ftp.gnu.org/pub/gnu/binutils
GCC_DIR=gcc-2.95.3
GLIBC_DIR=glibc-2.2.5
LINUX_DIR=linux-2.4.3
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.2.5

3. The kernel refuses to try to compile with GCC
3.2.x

4. Compiles Linux but has an error with U-Boot

BINUTILS_DIR=binutils-2.14.90.0.8

BINUTILS_URL=ftp://ftp.kernel.org/pub/linux/devel/binutils
GCC_DIR=gcc-2.95.3
GLIBC_DIR=glibc-2.2.5
LINUX_DIR=linux-2.4.3
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.2.5

5. This appears to compile both but we are using 2.4
headers instead of 2.6.

BINUTILS_DIR=binutils-2.14.90.0.5

LINUX_DIR=linux-2.4.21
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.1.3
GLIBCCRYPT_FILENAME=glibc-crypt-2.1

6. Tried to build using 2.6 headers. Build of the
cross compiler fails.
