    <p>This is a new thread started from post (<a href="https://stackoverflow.com/questions/12107885/libcurl-lib-where-can-i-get-it">link</a>).</p> <p>I have used the suggested curl library (<a href="http://curl.haxx.se/download/libcurl-7.19.3-win32-ssl-msvc.zip" rel="nofollow noreferrer">link</a>) for building libcurl into my dll. I link in libcurl_imp.lib and have created library routines for calling the curl methods. This all works a treat - BUT ONLY ON A 64BIT MACHINE? - if I try to run the same dll/binary app on a 32bit XP machine it just dumps out immediately. In fact all my applications abort - and they make no reference to my new library routines, they just use the dll. It seems that because I build in the cURL calls into my dll it immediately aborts the spawned process– I just get –</p> <blockquote> <p>1 + Done(134) testapp</p> <p>5656 Abort testapp</p> </blockquote> <p>I have a printf statement immediately after main but I get no output on the command line.</p> <p>I then removed all my new library functions from the dll apart from one, and in this all I do is –</p> <p><code>CURLcode res = curl_global_init(CURL_GLOBAL_DEFAULT);</code></p> <p>This one line causes all my apps to fail on 32bit when built into my dll – comment it out and they all work.</p> <p>As stated, the same dll/binary works fine on my 64bit machine. The 64bit machine has the same curllib.dll runtime as the one on my 32bit machine.</p> <p>For info, my build machine is 32bit, we have productions machines that are both 32 and 64 bit.</p>

    1. COFurther to this - the curl.exe contained in the .zip produces the same result (aborts immediately) when ran from the command line on my 32bit XP machine - works fine from 64bit...?

    2. COAnother thing... the curl.exe contained in the downloads under Win32-Generic (the 2000/XP ones) DO run on my XP machine. Only problem is is that there are no .lib's contained in these downloads!!! Does anyone out there know how to request a new libcurl windows build to be done as dare I say it, it would seem that 7.19.3 under Win32-MSVC does not work on 32bit OS.
