[Chicken-users] Sendfile Does Not Compile on Windows (Cygwin) with Chicken 4.0

[Yasuro]

Hello.

I am quite new at this; I have just started tinkering with Chicken 4.0. I apologize in advance if I said something trivially obvious to knowledgeable people.

I am trying to make the Spiffy egg work on Windows (Cygwin). Spiffy uses Sendfile, but I have trouble installing the Sendfile egg (The complete log at the end of this email). Here's the error message from chicken-install:

sendfile.o:sendfile.c:(.text+0x55d7): undefined reference to `_madvise'

Last time I tried with Chicken 3.4, I had the same problem. I could not fix this problem and had to give it up. Would you help me fix this issue, please?

On a related note, I had a little trouble installing the Openssl egg. I compiled and installed the Openssl library from the source, but I am not sure if it was necessary. Then I set the CSC_OPTIONS env variable the following way, because csc did not see seem to be able to find the header files and the library file. That fixed the problem.

CSC_OPTIONS "-I/usr/local/ssl/include -L/usr/local/ssl/lib"

Thanks!

Yasuro
