Hi All,
I was wondering if someone could give me a quick guide
as to the compilation/linking options when using
liblnp.h etc. I'm having a few difficulties.
I wanted to know how exactly to link in the shared library.
I tried installing it in the standard /lib and running
ldconfig (as root) on that dir to recognise it, I also tried
pointing to the directory containing it using the
$LD_LIBRARY_PATH env variable, but neither have worked:
I have referenced the liblnp.h in a c++ source file (which
I'm using to wrap LNP functionality) and then compiled it
sucessfully, but when I try to link it to my main() class,
in my make environment, I get:
simpleLNPTransport.o: In function
`simpleLNPTransport::simpleLNPTransport(void)':
simpleLNPTransport.o(.text+0x81): undefined reference to `lnp_init(char *,
unsigned short, unsigned char, unsigned char, int)'
simpleLNPTransport.o: In function `simpleLNPTransport::sendCORBA(unsigned char
const *&, unsigned char)':
simpleLNPTransport.o(.text+0x101): undefined reference to
`lnp_addressing_write(unsigned char const *, unsigned char, unsigned char,
unsigned char)'
simpleLNPTransport.o: In function `simpleLNPTransport::sendControl(unsigned
char const *&, unsigned char)':
simpleLNPTransport.o(.text+0x176): undefined reference to
`lnp_addressing_write(unsigned char const *, unsigned char, unsigned char,
unsigned char)'
collect2: ld returned 1 exit status
make: *** [nanOrbServer] Error 1
simpleLNPTransport is my cpp class file.
Thanks in advance,
Colin Ryan
