Found it
That is what Configure showed me
Configured for VC-WIN32.
You gave the option 'shared'. Normally, that would give you shared libraries.
Unfortunately, the OpenSSL configuration doesn't include shared library support
for this platform yet, so it will pretend you gave the option 'no-shared'. If
you can inform the developpers ([EMAIL PROTECTED]) how to support shared
libraries on this platform, they will at least look at it and try their best
(but please first make sure you have tried with a current version of OpenSSL).
and if you have a look at line 1126 in Configure you see:
if ($no_shared)
{
$openssl_other_defines.="#define OPENSSL_NO_DYNAMIC_ENGINE\n";
}
else
{
$openssl_other_defines.="#define OPENSSL_NO_STATIC_ENGINE\n";
}
now i'm totally confused no shared libs for win32?!
is it a bug?
