how to add libraries to the buildh.bat file

[FWExplorer]

Hi,

I'm getting missing externals from twitter, which I believe are found in libcurl.lib, in the harbour distribution.

What's the official way to add specific contribution libraries to buildh.bat?

When I try compile twitter.prg, the externals are

D.

You have to add these lines in buildh.bat to build it using BCC7:

echo %hdirl%\hbcurl.lib + >> b32.bc
echo %hdirl%\libcurl.lib + >> b32.bc

or add these lines in buildh32.bat to build it using Visual Studio Community

echo %hdirl%\hbcurl.lib >> msvc.tmp
echo %hdirl%\libcurl.lib >> msvc.tmp

Ok, thanks Antonio.

Got further, but there's still some missing externals

These seem to be referenced in

c:\harbour\comp\mingw\include\curl\curl.h


Should I put

c:\harbour\comp\mingw\include\curl

in the INCLUDE paths?

Please download and use this Harbour build and it should work fine:

https://github.com/FiveTechSoft/Harbour_builder/blob/master/harbour_win32_bcc_2020_10_19.zip

I'm pretty sure I extracted the Fivewin build a few months ago.

But I'll give it a shot, thanks.

Hi, FWExplorer !

Tell me, did you manage to work with CURL?

[FWExplorer]

It compiled correctly.

Unfortunately, the line

Code: Select all  Expand view  RUN

     aMatch  = HB_RegExAll( 'form action="(.*?)" method="(.*?)"', cPage, .F., .T. )
 

doesn't do anything. aMatch is empty afterwards, and then of course there's an array error on the next line

Code: Select all  Expand view  RUN

     cURL    = aMatch[ 1 ][ 2 ]
 

[Natter]

You're talking about a file curl.h ?

[FWExplorer]

No. Twitter.prg, in the samples folder.

[Antonio Linares]

twitter.prg uses this url:

https://mobile.twitter.com/session/new

but it seems as such url is no longer working

We need to find the current equivalent one

Ok, thanks Antonio.
