You wrapped this? :

or the declaration of XEmac_IntrHandlerFifo?
I wrapped the file that includes the above call XIntc_RegisterHandler(..)
but that did not help.
All files in lwip and the xilinx emac seem to have the
#ifdef __cplusplus
extern "C" { ...
around their headers.

No idea what the function looks like, but probably like this?
extern "C" void XEmac_IntrHandlerFifo(void*);
2)
Is the function really defined?
Try checking with the map file, if you have one,
or with something equivalent of nm or objdump.
The function is defined, when I use Ctrl+clicking onto XEmac_IntrHandlerFifo
the Platform Studio SDK points me to the function, which is located in
xemac.c.
But the linker does not find it ...
I have no idea what this file is, I never developed with Xilinx stuff.
There are probably others that can give you move advice, but:
- Could it be the other way around? That is, XEmac_IntrHandlerFifo has
c++ mangled signature, so you shouldn't extern "C" it?
- Is that file (xemac.c) part of some lib you need to reference in your
project somewhere?
- If not, is that file being compiled/linked?
Hope that helps,
Cheers,
