problem with curl

[marek.r...@gmail.com]

I am using harbour 3.2 (r2104281802) - downloaded from: https://sourceforge.net/projects/harbour-project/files/binaries-windows/nightly/harbour-nightly-win.exe.

I encountered a strange problem with libcurl. I compiled the sample contrib\hbcurl\tests\ftp_uldl.prg and it worked fine once or twice,  but most of the time it  crashes after CURL_EASY_INIT() without error message or with a message like this:

[hb_out.log]

Someone could help me?

The only reason I am responding is, you are a person of my own heart.

I  also have a D:\work\prg\ hb32 and hb34  etc.

I'm not into curl but, you may want to check out Victor's hb3.4 curl, he seemed to be into that.

It may be the same or updated, I'm not sure.

Scope it out.

I had a similar problem. Try libcirl.dll version 7.82.0  as in the picture.

I tried for a long long time to make curl+ssl/https to work in Windows. No luck. 

With mingw64 ... absolutely no way. With msvc supposedly it could work (I think Antonio Linares at some point made it work).

Since I focus on web apps, which I deploy on Linux (Ubuntu servers), I decided to focus on that environment. 

If you use VSCODE and Docker Desktop with WSL2 for example, it is possible to use curl.

I am using curl for accessing an API.

Hi,
Once I had similar problem with curl command line, caused by an
antivirus software blocking the access.

cheers,

hi,

have a look into HMG Forum
https://www.hmgforum.com/viewtopic.php?t=7289

EDK have upload imap_Curl.7z which use
libcurl.dll     7.85
libeay32.dll    1.0.2.21
ssleay32.dll     1.0.2.21

and modify Source to build new LIB

libcurl.a
libhbcurl.a

it use IMAP to get Email and have Function SendSMTP()

I have it working with my MSVC 2005 build if anyone has some specific questions. Pretty much worked out of the box with Viktor's 3.4 branch but maybe I am forgetting some issues, it was a while ago.

Hi Eric

We use msy64 on windows 10/11 and ubuntu linux for smtp, ftp, and http without any problems.  Without seeing your code, I would suspect that you creating new curl instances without calling curl_easy_cleanup()?
