[Mingw64-UCRT] libcurl causing build failure when using

[rorgoroth]

Hello, I recently updated my cross compiler to use ucrt rather than old msvcrt.

Enabling CURL causes a build failure, which doesn't happen when using mingw using msvcrt. Here is the build log: q3e.log

Specific error part:

Interestingly, that old version of curl used in q3e, as well as latest both build fine under the same cross compiler. Thanks for your time!

You may need to update the curl libs used as the ones included are compiled by certain versions of runtime?

Aka it must also be changed to use ucrt

I assume I need to build them with vs? I tried quickly copying the libs (and later, headers) from my mingw prefix but that caused further breakage 🥴

Okay, I've made some progress and managed to hack it up enough to build and run.

I've:

• updated all the curl includes to 7.80.0
• updated libcurl.a
• added libz.a
• Updated makefile:

--- a/Makefile
+++ b/Makefile
@@ -387,7 +387,7 @@ ifdef MINGW
     else
       CLIENT_LDFLAGS += -L$(MOUNT_DIR)/libcurl/windows/mingw/lib64
     endif
-    CLIENT_LDFLAGS += -lcurl -lwldap32 -lcrypt32
+    CLIENT_LDFLAGS += -lcurl -lwldap32 -lcrypt32 -lz
   endif

   DEBUG_CFLAGS = $(BASE_CFLAGS) -DDEBUG -D_DEBUG -g -O0

It seems to function as expected, it downloads files fine.

Okay one last update, I did a more proper solution: https://github.com/rorgoroth/quake3e/commits/master

I keep the original curl version, removed the zlib dep and add makefile option for mingw with ucrt. If you are interested, you can take it. If not, that's okay too. Feel free to close this now if you wish.
