libcurl library causing plugin to disappear from menu

[Anonymous]

Hello,

I'm trying to implement curl library into my archicad plugin. On MAC there are no problems with it, but on Windows I can only compile the code without errors, and then if I open AC21 on Windows it says that the plugin is outdated.

This is the code that causes the error:

curl_global_init(CURL_GLOBAL_ALL);

	

	CURL *curl;
	CURLcode res;

	curl = curl_easy_init();

	string urlString = "somesite";

	
	if (curl) {


		curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, FALSE);

		curl_easy_setopt(curl, CURLOPT_URL, urlString.c_str());
		
		curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

	
		
		res = curl_easy_perform(curl);

		WriteReport("CURL IS %s", urlString.c_str());
		
		WriteReport("CURL status is %i", res);
		if (res != CURLE_OK)
			fprintf(stderr, "curl_easy_perform() failed: %s\n",
				curl_easy_strerror(res));

		setProjectBuildups(userID);

		
		curl_easy_cleanup(curl);
	}
	

If I remove this code the plugin doesn't appear as outdated and it runs fine. I also notice that when I compile in VS2017 there is a libcurl.dll file in the build folder. Should I somehow include this .dll file in the add-ons folder ? Every help will be highly appreciated

Thanks in advance,
Julian

It's probably down to the way you link the curl library into the add-on. If you're using dynamic linking and library can't be found at runtime, the add-on won't load. ARCHICAD always says the add-on is outdated no matter what the problem is.

You could either bundle the dll with the add-on or try static linking instead.
