Greetings to everybody here!

Could be a silly question.But I failed to compile the exampe program
under \lazarus\fpc\2.7.1\source\packages\libcurl\examples\testcurl.pp

I got an error something like :
Code: [Select] cant' find unixtypeWhen I tried to add unit unixtype to
the projecct ,it complained again:
Code: [Select]
could not find ptypes.inc

I stopped.I think this coul not work.

Is there anything I missed?

God,I was always encountering such issues that the
project(compiler)can't find some unit ,I can search them in some
folders and added them into the project by Project->Options->Paths.But
to be honest,I don't quite understand 'Other unit files','Include
Files','Libraries',to which I should add the file (In C/C++ I know
whether a header file ,source file(s) or a lib file is missed.).So
sometimes it works,sometimes the compiler still complains after I feed
the files to the project.

Help would be much appreicated.

Regards,
Sam

Those are unix libs, IOW the header is simply not supported for
Windows. 

Libcurl is quite unix centric, and people on Windows usually use a
socket suite(Indy, Synapse) or something from the wininet api/unit.
(which has FTP and http methods that also honor systemwide configured
proxies)

Moreover, there is no "one" C compiler on Windows, so there could be
up to 4 different libcurls in common use (cygwin or mingw could also
be static, and MSVC, BCB in DLL form)

Got it.Thanks.May I know what's the best recommendation of a
crossplatform library in freepascal/Lazarus then?

Would be nice to patch it with note in the source that the program is
unix only just to make it clear.

I think that differs for each programmer. I find Synapse quite
workable; e.g.
http://wiki.lazarus.freepascal.org/synapse#From_an_HTTP_server
AFAIR, Synapse also has proxy support, but haven't used it...

Sorry,do you mean Synapse is cross-platform,both for win* and
*nix?Thanks.

Yes, I do mean Synapse is cross-platform. Have run it e.g. on Windows
and Linux.

Synapse for code oriented (though there's visual synapse, but I don't
know its state), lnet for component based or just use fcl-web (not as
complete as others AFAIK, but should be enough for most usage and has
a better future support since it's officially part of fpc). All of
them are cross platform.

I'm Sorry,In windows 32bit system,In the
'C:\lazarus\fpc\3.0.2\units\i386-win32',I cant find libcurl,how can i
build it?
