[Buildroot] MSB vs LSB mips library files

[Buildroot] MSB vs LSB mips library files

[jing han]

Hello,

I downloaded buildroot-2009.05.tar.gz and built a mips32r2, o32 environment in my machine  (fedora core 5   2.6.15-1.2054_FC5).

After the make is finished, I checked through the mips files in my mips environment, I found that all the files in buildroot-2009.05/build_mips/staging_dir/usr/bin/* directory are LSB files, all the library files in buildroot-2009.05/build_mips/staging_dir/usr/lib/* directory are MSB files, which 
supprise me a lot and I don't want. 

I compiled a simple program with mips-linux-gcc which only print "Hello World", the result of "file a.out" is as follows:

a.out: ELF 32-bit MSB executable, MIPS, MIPS64 version 1 (SYSV), dynamically linked (uses shared libs), not stripped

I don't want MSB executables, I  want LSB executables.  Can you tell me  why  I  have  MSB mips library files? What can I do in order to have LSB mips library files and to make my mips executables LSB files?

Could you tell me which option I could choose in order to avoid MSB library files?

Thank you in advance and I'm looking forward to hearing from you soon.

Best Regards
jing

Some of the files in build_mips/staging_dir/usr/bin/ are the
cross-compiler and other cross-compilation tools. So they are compiled
for x86 and generate code for MIPS. Or can you provide an example of a
binary in this directory that is LSB, but not for x86 ?

In build_mips/staging_dir/usr/lib/, are the libraries compiled to run
on the target, so compiled for the MIPS architecture.

Use mipsel instead of mips ?
