Re: [ECOS] Re: Can not compile API file

Hello everyone,

Thanks,Ross.
As I changed PPOUT.C to ppout.c I succeeded to build libtarget.a.

But when I tried to Make application with libtarget.a I am encountered 
enigmatic errors.
Below is make result.
It looks that tcpip sources occure many "undefined reference to" 
errors,although I never touched any tcpip sources.
My application program just create one thread and never concerned with 
tcpip. I append it below.
It is true I selected "net" packet in building, but never appeared these 
errors before I included pseud-USB driver.
I greped `___udivsi3_i4i' but no hit.
What are they related to my including pseud-USB driver ?
Why this phenomenon happens ? Please teach me.

I send build result log also.
