Hi Monks,

I have problem installing the module Crypt::OpenSSL::AES. I didn't understand anything, what the problem is. Can someone actually tell, where is the problem ?I am just pasting, what is displayed in the Command line.

    This module builds and installs fine for me on Windows. I think your problem might be that the openssl headers (specifically, openssl/aes.h) are not being found, and hence the subsequent syntax errors.

    Where is the openssl library located on your machine ?
    Did you at any time during the build see any messages about "no such file" or "probably harmless" ? (They would have occurred before the section that you posted.)

    Cheers,
    Rob

    Those are errors from your C compiler, which means that your build environment is broken in some way, or the files it is trying to compile are broken.

    Are you able to compile other XS perl modules? What about other normal C programs?

    Is this error coming from the CPAN shell, or did you download and unpack the module by hand. Is it possible that the unpacked source code became corrupted in some way?

    What version of perl are you using an which c compiler? As I recall, Strawberry perl uses GCC, and Active State perl uses Microsoft C++. (I could be wrong about that though)

    Did you install the prerequisites mentioned in the README file? You'll also need a C compiler and build tools. If you're using ActiveState Perl try:

    ppm install MinGW

      You'll also need a C compiler and build tools.
      Those errors are spit out by the C compiler. So, obviously, there is one installed and found already. Same holds for dmake.

        of course you are right, I posted while half asleep (again). I should have stayed in bed today.
