Cross compiled toolchain problem

[Swapneel Shah]

Hi

I could resolve the error, but found that XFree86 code does not build
executables those are needed to be executed on the host platform using host
compiler.  i.e in this case mkg3states executable will be built using cross
compiler and hence when the build tries to use it, gives Segmentation fault.

I went ahead with creating a root file system and started compiling XFree86
in that environment.  In that environment, encountered following error

undefined reference to ecvt
undefined reference to fcvt

I have found couple of posts on the net where it says, this problem has been
fixed in the latest snapshot of uClibc.  I am using the latest snapshot but
still I am getting the problem.  Does anyone know how to resolve this
problem?

Regards
Swapneel Shah
