Hi Simon,

I tried building a new linux synth target with the lwip_sequential package
selected (using the ecos supplied i386-elf GCC).

I ran into some errors when I try ti build the target.

First there was a missing bracket in
packages/net/lwip_tcpip/current/src/core/ipv4/ip.c
Line 413.

After fixing that, I get a bunch of errors:

Wall -Wpointer-arith -Wstrict-prototypes -Wundef  -Wno-write-strings
-g -O2 -ffunction-sections -fdata-sections  -fno-exceptions
-fno-stack-protector -Wp,-MD,src/api/tcpip.tmp -o

I'm sure this port compiles fine but somehow my build seems to be
missing something. I've checked and I have
the serialio.h file

$ find packages/ -name serialio.h
packages/io/serial/v3_0/include/serialio.h
$

Also, are the warnings expected?

Thanks,
