Hello, I'm trying to compile a static libcurl library, but without success.
I downloaded the source code for libcurl version 7.55.1 available at link . After the download completes I extracted the contents to the local disk.
I opened the Developer Command Prompt for Visual Studio and used cd C:\curl\winbuild . In this folder there is an instruction file of how to compile for Windows. I ran the following command line at the prompt.
nmake /f Makefile.vc mode=static DEBUG=no MACHINE=x86
When the process finished, there were files in the C:\curl\builds\libcurl-vc-x86-release-static-ipv6-sspi-winssl directory.
I added the C:\curl\builds\libcurl-vc-x86-release-static-ipv6-sspi-winssl\include directory to Diretórios de Inclusão Adicionais and C:\curl\builds\libcurl-vc-x86-release-static-ipv6-sspi-winssl\lib to Diretórios de Biblioteca Adicionais .
And in my source code I added the following code to the top:
#include <curl\curl.h>
#pragma comment(lib, "libcurl_a.lib")
When I try to compile the sample code from this address link I get several errors about symbols indefinite.
1>main.obj : error LNK2019: símbolo externo indefinido __imp__curl_global_init referenciado na função _WinMain@16
1>main.obj : error LNK2019: símbolo externo indefinido __imp__curl_global_cleanup referenciado na função _WinMain@16
1>main.obj : error LNK2019: símbolo externo indefinido __imp__curl_easy_strerror referenciado na função _WinMain@16

1>main.obj : error LNK2019: símbolo externo indefinido __imp__curl_easy_cleanup referenciado na função _WinMain@16
I have already tried using different options for compilation, I even compiled using the project for Visual Studio which comes bundled with the source code of libcurl and is located in C:\curl\projects\Windows\VC14 . Also unsuccessful.
I'm waiting for a tip to solve this problem, thank you.
