[lwip-users] [lwip] link error

[byung-hyun jang]

Hi,
while I am testing the sample http/1.0 server program which is at the end of 
lwip manual by Adam, I got an linking error.
I am running the win32 ported version of lwip by Florian.
"ttpServer.c"is the file name I made to test the program.

--------------------Configuration: test - Win32 Debug--------------------
Linking...

test___Win32_Debug/test.exe : fatal error LNK1120: 9 unresolved externals
Error executing link.exe.

test.exe - 10 error(s), 0 warning(s)

-----------------------------------------------------------------------------
I definitely included the file "api_lib.c" and "api.h" which has the above 
functions in the project. I have no idea about this.
Anybody who know this problem??
Florian, I fixed link error "_bcopy" through your instruction but why this 
error at this time??


Thanks,
Byung-hyun Jang
