undefined reference to `_IO_getc'

[lylai]

Hello.

Can you help me a bit with this error?

/bin/sh ../../libtool --mode=link ucfront-gcc arm-linux-elf-gcc   -O2 -g

Another side question is that, a program I was trying to port would
execute an exe file it builds in the process to generate some files. How
should I deal with this?

Thank you for helping out.
