LOTS of errors while trying to compile md5 code from site

Hello.
I tried to compile the code from http://www.faqs.org/rfcs/rfc1321.html which should calculate an md5 from a string.
I got the following errors:

I copied and pasted the code directly, so I don't know what I'm doing wrong....

(PS.: is there also an option to tell the compiler explicitly to compile the files as C and not as C++ , or should I just give the files a C-extention in stead of .cpp ??)

sunnycoder

Are you sure you have the files copied properly and you are not mixing some of the code around ....

I see MD_CTX defined there

Hi, and thanks for your replies.

sunnycoder, yes I am sure that that's not the error, I checked it several times....
aib_42, no, I don't have changed this part, neither have I more than one file with the same name .....

Did one of you tried to compile the files ??? (and, if so, did you had errors ??)

teratoma

The include path needs to be supplied to the compiler. This is usually in the form of "-I<filename>" on the command line.

aib_42

I see you have renamed md5.c to test_md5.c. If this is the case for other files too, you would have to modify the #include lines all over the source code.

Thanks,
teratoma, I did this (I'm using Visual studio)
aib_42, It's not the "md5c.c" I renamed but the "MDDRIVER.C", which was a "sample testing program"

I'm starting to get desperate....
