HTTP downloading from R1Q2- which version of libcurl to use?

[Knightmare]

I've been looking at adding the HTTP auto-downloading feature from R1Q2 to my engine, but R1Q2's source (latest b8102 version) omits the libcurl headers and static library needed for this feature. Has anyone here tried to add this and run into this problem?

I was wondering if I could just take any version of libcurl and compile it into a static library and link with it. For example, the one included with the Doom3 source.

try it?
most libs aim for backwards compatibility, or rename things where that can't be achieved.

I ported Warsow's libcurl-download code to netQuake, with very little adjustments.
And since warsow is based on Quake2, it might work even easier for you.

Uh, what difference does it make? Once your implementation hits the wire, HTTP 1.1 takes over. It's a spec. Makes zero difference what version of CURL (or any other client library) you use

Edit: I see -- you're hoping to basically copy/paste his implementation into your project. Well, in that case, because of the maturity of libCURL, I think you'll be fine with the latest stable release. Their API hasn't changed dramatically in a long, long time (like 10 years).

libcurl.lib included with q2pro on github might work.

I got the libcurl from Doom3 compiled into a lib. It was easy enough, as a project file for VS2003 is included.

I'm just intending to copy/paste this as a quick addition to KMQ2. I've gotten a few requests from people who use KMQ2 as a multiplayer client to add HTTP download support, and I don't want to devote much time to it, as there are other features I'd rather work on.

If you want i just compiled the latest version of libcurl for msvc

[Knightmare]

Just got that version (7.37.0) compiled into a .lib as well.

Ok m8 old one from Doom3 caused the server list to come up empty but after upgrading it works again.

Even found a C++ wrapper which might work out nicely for Doom3.

add libcmt.lib to ignored libraries also link curl with the static msvc runtime eg. /MT not /MD

I have it compiled and ready to go and curl_easy is in the curl sources believe me its a library export.



I use it In Doom3 which also uses curl_easy

edit: Ah you ment that specific function oki.

Also included is the c++ wrapper libraries for curl but you probably wont need those in a C based engine.

Also got some undefined crap untill i played a bit with the project settings now it works just fine, ill investigate the steps i took and post them back here.

Edit again: ok i see now you are linking to the dll version, that wont work with the modified curl.h from me its static only. If you insist on using the dll leave curl.h alone but it works just fine if you link it statically.
Thing with the static lib is that you need to know what windows libraries curl depends on and add them to the linker as well, those are ws2_32.lib wldap32.lib advapi32.lib normaliz.lib some of them are probably allready in the linker but double check just in case. My bet would be that you are missing ws2_32.lib and wldap32.lib.
