Hello:
I'm trying to build GCC 3.4.2 with newlib 1.12 (using MinGW) for the
MIPS targets. I need to build the big-endian and little-endian C++
libraries for the MIPS-elf targets. I was successful in building the
big-endian C++ libraries (this what the options defaulted to). I am
unsure on how to build the C++ libraries for the little-endian
targets. When building newlib I suppiled the -EL compile target
option, and then used GCC to build and install the little-endian
libaries. It seemed like the little-endian libraries were built
however, I get linking errors when I build my test programs.
I looked online for help and came across using the multilib options.
I tried using multilib and only the big-endian libraries get built.
When I invoke the -print multilib compiler option I get blank.
1. How to build the tools chain for various target endianess
combinations?
2. Is it possible to build a set of libraries by running one build?
If yes, do I need to use multilib option? If so, how to use it ?
MULTILIB_OPTIONS = EL/EB
MULTILIB_DIRNAMES = el eb
Thanks
