Re: Linking error with DINTEGER_ONLY

[Alex Gonzalez <langabe at gmail dot com>]

Hi,

A a follow up, compiling without any extra CFLAGS_FOR_TARGET, I am
also having problems to get iprintf to work.

It gets to __sfvwrite, in the line buffered section, but never
actually calls fp->_write.

I would expect the library to call the provided write stub at some point.

I have copied the libnosys tree to a new folder under libgloss, and I
have changed the configure files to build an architecture specific
libgloss library. I then compile my application with it.

I have only provided a stub for write, as I expect to provide the
stubs as my code needs them.

I would appreciate any help as I am not sure what to try next.

Regards,
Alex
