NIOS II 5.0 and new format of .cdtbuild ?

Hi,

I had too had this problem and found this in a lwip readme.txt:

.cdtbuild: Eclipse plugin default build file. Normally generated, but

included here to provide the default compiler include PATHs. If the

example will not build with this file, remove it, and add the following

"Include Paths" to the nios-elf-gcc general configuration options (available

in the "Properties" of the sample project):

../lwip-0.7.1/src/include

../lwip-0.7.1/src/include/ipv4

../lwip4hal/include

../apps

Deleting .cdtbuild from altera\kits\nios2\examples\software\lwip_web_server\ seems to do the trick.

Regards,

Aidan
