PlugIn SDK - Http Request

[paon.m]

Hi

I developed a CC12 plug-in that sends soap request to a Web Service. To do that I'm using libcurl (curl ) and it works, but to make it work on Mac I have to replace the OS libcul lib with mine, because even if the liburl has been compiled in static_mt the the plug-in try to resolve it  with the OS one. I've tried a different solution like https://pocoproject.org/index.html  but it conflicts with SDK headers (you can resolve it modifing WShukHeaders.h in this way C++ Redefinition Header Files (winsock2.h) - Stack Overflow  but it really sucks as solution ).

Does anyone know a good solution to make http requests in the plug-in?

Many thanks in advance.

Hi Massimo,

I'm using curl too and simply integrated the source code after configuration into my project. This avoids your problem and compile time isn't much affected. Maybe you want to choose this option too?

Best, Peter

Hi Peter,

Can you share with me some tips about how do that?  I've tried to add the VS projects present in curl package 'libcurl' and 'curlsrc' to my solution but the linker still serch for an external link whilke compiling my plug-in. I also tried to add the source files from the 'libcurl' project to my project but I get this error :

Error    1    error C1853: 'C:\Users\paon.m\Desktop\SourceTree\IndesignPlugIn\_built\Indesign_CC_version_2015\\objdx64\PageBuilderConnector\PageBuilderConnector.pch' precompiled header file is from a previous version of the compiler, or the precompiled header is C++ and you are using it from C (or vice versa)    C:\Users\paon.m\Desktop\SourceTree\IndesignPlugIn\libs\curl-7.37.0\lib\amigaos.c    1    1    PageBuilderConnector

Many thanks in advance

Hi Massimo,

You should use static library.

Check this link:

Hi Karoly

The problem is on Mac, to make the plug-in works I have to copy:
licurl.a
libcurl.la
libcurl.4.dylib
libcrul.dylib

in /usr/locol/lib, otherwise Indesign crash. I'm looking for a way to avoid to copy those files

Hi,

Including libcurl in C project - Stack Overflow

"3down voteaccepted

Mac OS X comes with a copy of libcurl, so your application doesn't need its own copy. You didn't mention the version of Xcode you're using. The following applies to 3.2, but may not work in 4. To use the version of libcurl provided by the system, go to Project, then Add To Project. In the dialog that comes up, type /usr/lib and press enter. Find libcurl.dylib in the list of files and click Add"

I use libcurl.4.dylib

It works for me.

Hi

I'm using Xcode 5.0.2 for CC10 and CC11 on MacOs 10.9, Xcode 7.2.1 for CC12 on MacOs 10.11 as per SDK documentation.

the problem is I'm using a different version of libcurl that is not the same of the Max OS X one. So if at runtime it links to the libcurl in /usr/lib Indesign crash, putting those libraries in /usr/local/lib resolve the issue because they are taken at runtime instead of the ones in /usr/lib

[Karoly65]

Maybe you need to create separated projects for all CC variation.

eg. CC 2014, CC 2015, CC 2017 and CC 2018

I have different projects for CC variations.
I have tried your solution but Indesign still crashing:

[Karoly65]

Did you use libcurl.4.dylib for your CC 2017 project?

If "yes" in this case I can only guess:

1.  you use a wrong system libraries

     Check: remove all libcurl references from project -> compile - > test

                 If test is OK  goto point 2.

2. your libcurl.4.dylib is wrong for your selected and precompiled Adobe libraries

    Check your system libraries settings in your project for different xcode versions

If I have to guess point 2. your real problem:

- installed systemlibraries are mixed in your project (eg. lib path point to a fail  system library version)

  or

- wrong systemlibrary settings (eg. your OSX 10.11 systemlibraries contain fail libraries)

I implemented the Peter's solution and it works! It was quite hard compile lib curl with Xcode , if someone needs help about that I could help

[Forever Fan]

@paon.m do you have any sample or github location which I can refer to? I am trying to interact http api's in plugin. Thanks
