Sorry, I have activate the option "don't search in disabled code". So, yes, you
since INT_MAX is used, you have to define it (or add limit.h) in your cc.h. For
LARGE_INTEGER, it a Windows specific type, only use in the win32's sys_arch.c
(if you test the win32 port, you shouldn't have any problem to build it, since
windows.h is included in sys_arch.c).

msg.w.len is an "int", same for write_offset, so, on a 32bit compiler, you
could have a value > 0xffff (since "int" types are target/compiler dependant).
If you have this warning, I suppose you use a 16-bit compiler. In this case,
you can ignore this warning.

This is a repeat response - the first one may have been bounced due to
incorrect mail setting.
MAX_INT appears in api-msg.c, line 535, function netconn_alloc().
LARGEST_INTEGER in ..\ports\win32\sys_arch.c lines 46 and 57. I am using
files from this port in my attempt to start the new port.
As an aside, my compiler is questioning line 947 from api-msg.c:-
if ((conn->write_msg->msg.w.len - conn->write_offset > 0xffff)) { /*
max_u16_t */
len = 0xffff;
with a warning that the comparison is always zero, which does beg the
question how can a 16-bit variable/result ever exceed 0xffff?
Keep in mind this is the starting point for me and obviously I have to
walk the learning curve. I am working with lwip-1.3.0.
regards,
davidm
