[uClibc] How can I use uClibc ?

["박경택\(Park, Kyoung Taek\)"]

Dear all,
 
Now, I am planning to use uClibc for pthread facilities. I have tried some, but I need a right direction. Please help me.
I don't know what method is right thing to use uClibc. Should I use glibc for this?

Best regards

Methods that I have tried are:

 
[#1] Use of uClibc-0.9.26 ONLY
=====================
( I think that change of inclide and lib path will be enough, but it was not.)

1. Download uClibc-0.9.26.tar.gz
2. Build this package using gcc 2.95.3 20010315(release). This comes from chip vendor.
3. Add uClibc include and lib path to existing build env.
4. I have got some compilation error to use uClibc header files like below.

                 from jpeg_network.cpp:7:
/work/ddp1000/ktpark/WORK/uClinux-2.4/usr/arm-linux-uclibc/usr/include/bits/in.h:69: ANSI C++ forbids data member `ip_opts' with same name as enclosing class


[#2] Use of pre-compiled binary, arm-elf-20030314 from http://www.uclinux.org/pub/uClinux/uclinux-elf-tools/
======================
1. Download arm-elf-tools-20030314.sh and install
2. Build our sw using this toolchain.
3. I have got some errors like below.

In file included from /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/asm/hardware.h:16,
                 from fipuser_linux.c:10:
/usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/asm/arch/hardware.h:147: #error "Configuration error: No CPU defined"
 

[#3] Use of uClibc toolchain builder(gcc-2.95) from http://www.uclibc.org/cgi-bin/cvsweb/toolchain/
========================
1. Download toolchain.tar.gz
2. Edit makefile and uncomments ARCH:=arm var
3. Run make
4. I have got some errors lile below.
