Additionally * this file is also included and used when building the library. * * If compilation fails on this file it is certainly sure that the * problem is elsewhere. It could be a problem in the curlbuild.h * header file, or simply that you are using different compilation * settings than those used to build the library. * * Nothing in this file is intended to be modified or adjusted by the * curl library user nor by the curl library builder. * * Do not deactivate any check, these are done to make sure that the * library is properly built and used. * * You can find further help on the libcurl development mailing list: * http://cool.haxx.se/mailman/listinfo/curl-library/ * * NOTE 2 * ------ * * Some of the following compile time checks are based on the fact * that the dimension of a constant array can not be a negative one. * In this way if the compile time verification fails, the compilation * will fail issuing an error. The error description wording is compiler * dependent but it will be quite similar to one of the following: * * "negative subscript or subscript is too large" * "array must have at least one element" * "-1 is an illegal array size" * "size of array is negative" * * If you are building an application which tries to use an already * built libcurl library and you are getting this kind of errors on * this file, it is a clear indication that there is a mismatch between * how the library was built and how you are trying to use it for your * application. Your already compiled or binary library provider is the * only one who can give you the details you need to properly use it. */ /* * Verify that some macros are actually defined. */ #ifndef CURL_SIZEOF_LONG # error "CURL_SIZEOF_LONG definition is missing!"
