使用Visual Studio编译libcurl（布尔值未定义）

Question

I want to compile curl from source inside a Visual Studio project.

I get this error (and a lot more):

curl\src\tool_sdecls.h(67): error C2061: Syntax Error: Identifier'bool' (..\..\..\framework\libs\curl\src\tool_cb_dbg.c)
curl\src\tool_sdecls.h(68): error C2061: Syntax Error: Identifier'bool'is_cd_filename' (..\..\..\framework\libs\curl\src\tool_cb_dbg.c)
curl\src\tool_sdecls.h(68): error C2059: Syntax Error: ';' (..\..\..\framework\libs\curl\src\tool_cb_dbg.c)

The source of this file is:

65:  struct OutStruct {
66:      char *filename;
67:      bool alloc_filename;
68:      bool is_cd_filename;
69:      bool s_isreg;
...

It looks like bool is not defined for some reason. I tried defining HAVE_BOOL_T but nothing changed.

Any idea? Thanks

To solve the problem I added the folowing to curl_config.h

//for undefined bool error
#if _MSC_VER > 1700
    #include <stdbool.h>
#else
    #ifndef bool
        typedef int bool;
        #define false 0
        #define true 1
    #endif
#endif

//for warning C4005: 'POLLIN' : macro redefinition error
#define _WIN32_WINNT 0x0501
