[Opensc-devel] Problem developing in OpenSC project

[Danilo N. <dan...@gm...>]

Hi,

I'm trying to develop in OpenSC project and I modified opensc-tool.c
I added a code block and in this code there is "int res = sc_load_foo(s);"
The function sc_load is declared in /src/libopensc/opensc.h (int 
sc_load_foo(char *);) and is implemented in /src/libopensc/card.c
When I try to compile project I get this error :
"*undefined reference to 'sc_load_foo(s)'*" in opensc-tool.c
But in opensc-tool.c there is the line #include "libopensc/opensc.h" and 
in card.c there is #include "internal.h"
and in internal.h there is #include "libopensc/opensc.h"
Why when I try to do make I get this error?
Anyone can help me?

Regards,

Danilo
