Hi Anitha,

Hi James,

curl i have already compile using commandline

nmake -f Makefile.vc mode=dll WITH_SSL=dll WITH_ZLIB=static mode=static debug=no machine=x86

And i received the libcurl_imp.lib file that does not resolve the imp errors. As per reference i have included Windows SDK libraries.

#pragma comment(lib, "wldap32.lib")
#pragma comment(lib, "ws2_32.lib")
#pragma comment(lib, "winmm.lib")

Even its not fixed and same issue persist. Even i have set the SDK path in command problem before compile but nothing helps Sad.

Thanks,
Anitha.S

Hi Anitha,

A couple of things to try.

Looking at your 'nmake' command, you've specified two mode options, 'mode=dll' and 'mode=static'.

When I build curl (using CMake to create "NMake Makefiles"), I have to build it twice; once to create the shared library support files (libcurl.dll and libcurl_imp.lib) and once to build the static library (libcurl.lib). If I specify both dynamic and static libraries at the same time, it doesn't seem to create the static library file. Maybe having both options together might mess up the import libary file too.

Also, regarding import library file, make sure you are building a recent release of curl, e.g. 7.71.1

As an alternative to building curl yourself, you could also download the compiled version that the PHP-devs use:
https://windows.php.net/downloads/php-sdk/deps/vs16/x86/ (for a VS16 x86 build of Apache).

The sources and sample nmake commands can be found here:
https://github.com/winlibs/cURL

Cmake should be able to find the libcurl.lib and the curl include files. If everything is correct Cmake reports
CURL_FOUND ............... :
and
Curl include directory........... :
