Hi :-)
The problem is:
When compiling programs made in language 'C++' using:
# g++ myprogram.c -llnp
The g++ would not compile and the follow messages appeared:
/tmp/ccXFr7VZ.o: In function `main':
/tmp/ccXFr7VZ.o(.text+0x95): undefined reference to `lnp_init(char *, unsigned short, unsigned char, unsigned char, int)'
/tmp/ccXFr7VZ.o(.text+0xd7): undefined reference to `lnp_integrity_write(unsigned char const *, unsigned char)'
collect2: ld returned 1 exit status
Solving the problem :-)
1- Edit the file ItsDir/lnpd+liblnp/liblnp/stub.c
Add the line:
#define F_SETSIG 10
Change all occurrences of:
rcv_state++;
by
(*(int *)&rcv_state)++;
2- Edit the file ItsDir/lnpd+liblnp/liblnp/Makefile
Change all occurrences of:
'gcc' by 'g++'
3- Write:
$ make realclean
$ make
That's it, now you may compile all programs written
in 'C++' language.
