libcurl.dll Usage ?

[Mel Smith]

Hi All:

   How do I 'link up' libcurl.dll so that its internal functions can be called by  a Harbour app that I'm building. ?

   (I'm not familiar with .dll usage)

Thanks !

Hi Mel,

did you try the contrib hbcurl?
AFAIR it should work very well using dll.
I'd try to link it statically but with no luck.

Thus, setting HB_WITH_STATIC_CURL=no in your hbp script, you should obtain what wanted.
Best regards.

Hi Maurizio::

There are : c:\harbour\lib\hbcurl.lib, c:\harbour\lib\hbcurls.lib, and then c:\myapp\libcurl.dll, and I can't find examples of  calling functions embedded in external .dll files.

 Can someone provide an example of using these three curl-related files to access a function in an external .dll file ?

(btw, in xHarbour, it seems quite straightforward to 'load' the external .dll file using LoadLibrary(), then dllcall(some function), then Free the library with FreeLibrary(). But, I would rather stay with Harbour .)

Thanks for your response.

Hi Mel,
AFAIK it's the contrib library itself that take charge of dll loading.
I guess that curl_global_init() does the job.
To have an idea about hbcurl functions calling syntax you could take a look to contrib\hbcurl\tests\ftp_uldl.prg.
In addition, I remember a thread in this list in which  Paola Bruccolieri sent an example of http usage.

Best regards.

Hello Harbour Users,

I am used to do cUrl via command line, but now I need to do it via the cUrl library.

I am replying this old thread with the hope to have better chance of getting related info.

First step into hbcurl contrib is by doing contrib\hbcurl\tests\ftp_uldl.prg.

Unfortunately I failed compiling this prg with this error:

LINK : fatal error LNK1181: cannot open input file 'libssh2.lib'
hbmk2: Error: Running linker. 1181

as I reported in https://groups.google.com/g/harbour-users/c/NKgWDjs41UE

Could someone help me with info regarding this?

I build hbssl and hbcurl contrib some time ago as explained in here:
https://groups.google.com/g/harbour-users/c/ICJ6SfxWlqw/m/Hl8Jm1hBAwAJ

Did I miss something when I built the contribs? Or do I have to add something to let hbmk2 be able to build the contrib\hbcurl\tests\ftp_uldl.prg?

Thanking you in advance,

budyanto
