[GRASS5] Vect_get_point_in_poly

Hi folks:

I've tried to use the function Vect_get_point_in_poly to develop a module
in a linux machine and obtained the next messages:

I've found the unrecognized functions in the source
files in .../src/libes/linkm/ directory but have no idea about how make
them easy to find from my program.

Probably it's because my inexpertise in GRASS programming, sorry about
that, but has anybody some idea on how to fix it.

Thanks in advance

Paco.

you have to add $(LINKMLIB) to the LIBES line.

The references are stored in:
src/CMD/generic/make.mid

In your case:
LINKMLIB = $(LIBDIR)/liblinkm.a

So with $(LINKMLIB) it may compile.

Hope this helps,

Markus
