Bug 14793 – net.curl.download https broken - windows

curl does not work properly with https on windows: http = HTTP(); http.handle.set(etc.c.curl.CurlOption.ssl_verifypeer, 0); // do not verify ssl string content = std.net.curl.get("https://.....", http).idup; // works std.net.curl.download("https:// .... ", localpath, http); //crashes Only download is affected, .get works fine (with deactivated ssl). Probably windows-only.

I can't reproduce this, can you post a full program with working URLs? The download function was broken during 2.068 development, but was fixed before release: issue 14712

Can't reproduce and no reply in over a year, closing.

Actually the timeline doesn't match up with 17622's. (In reply to Yury Korchemkin from comment #3) > Reproes with DMD32 D Compiler v2.073.0 Can't reproduce here with that version. Try 2.075.0?

Figured that out — the problem was with libcurl.dll being not installed on the machine and not copied into the folder with executable. Copying the DLL solved the problem. Resolving the bug.

If there is a reproducible problem with the installer not installing libcurl properly, please file that separately.
