Ahh there we go. I didn't look quite so carefully, but that solves the
compiling problem. I don't have an Nspire, so I can't test it.

However, this shouldn't be a problem with tilp, as it doesn't depend on
libticalcs2...does it?

Also, is there a reason why the same code apparently builds successfully
on other platforms?

If one examines the files in libticalcs2-1.1.0/src, you will find these
two lines on lines 68 and 69 of nsp_vpkt.h:
uint16_t nsp_src_port;
uint16_t nsp_dst_port;

You will find these two lines on lines 110 and 111 of nsp_vpkt.c:
uint16_t	nsp_src_port = 0x8001;
uint16_t	nsp_dst_port = PORT_ADDR_REQUEST;

This is, indeed, a case of multiple definition of the variables, and
causes the linker to fail.

If you change the lines 68 and 69 in nsp_vpkt.h (.h, not .c !) to:
extern uint16_t nsp_src_port;
extern uint16_t nsp_dst_port;

then libticalcs2-1.1.0 will configure and make without the linker errors.

Whoever is in charge of libticalcs2 should correct this file, as multiple
people have reported this error with tilp2, tilp, and tiemu.

Fails with same error but different message on Mac OS X 10.5.2 with both
gcc-4.0.1 and gcc-4.2.1. See Bug 1849837.

ld: duplicate symbol _nsp_src_port in .libs/libticalcs2_la-nsp_cmd.o and
.libs/libticalcs2_la-calc_nsp.o

I've gotten a similar error under Mac OS X 10.3.9.  The cause seems to be
given earlier in the error messages:
ld: multiple definitions of symbol _nsp_dst_port
.libs/libticalcs2_la-calc_nsp.o definition of _nsp_dst_port in section
(__DATA,__common)
