No additional output is produced when I changed both of the `eval($fcn)` commands near 774. One thing to note is that to get this to actually export the functions, I had to copy the export block from the SHA.pm module like below, otherwise, I would get errors when trying to import the function names. `@EXPORT_OK = qw( hmac_sha1 hmac_sha1_base64 hmac_sha1_hex hmac_sha224 hmac_sha224_base64 hmac_sha224_hex hmac_sha256 hmac_sha256_base64 hmac_sha256_hex hmac_sha384 hmac_sha384_base64 hmac_sha384_hex hmac_sha512 hmac_sha512_base64 hmac_sha512_hex sha1 sha1_base64 sha1_hex sha224 sha224_base64 sha224_hex sha256 sha256_base64 sha256_hex sha384 sha384_base64 sha384_hex sha512 sha512_base64 sha512_hex);` [download] With this block commented out, printing out the export list gives no output.

Your module is more modified than you stated. It's not possible to continue without seeing it.	[reply]

I hope it's not a problem to put this much code in. Here is the Digest::SHA::PurePerl module I am using. The only modifications are the two things I mentioned in this thread: adding the exports to get it to actually export the functions, and removing the dump / load functions and use FileHandle include. Everything I removed is still there, but commented out. Read more... (55 kB)	[reply] [d/l]

Works fine for me, even without the `@EXPORT_OK` change. You'll need to find out why the loop that starts with `for $alg (1, 224, 256, 384, 512)` doesn't get executed for you. Start by making sure you are loading the module you think you are loading. You can do so using `use Cwd qw( realpath ); print(realpath($INC{'Digest/SHA/PurePerl.pm'}), "\n");` [download] If you are indeed executing the module you think you are executing, you've probably got a very serious problem with your Perl build.

I decided to unroll that loop to some extent and manually create one of the functions, sha256, as follows: `sub sha256 { my $state = _shaopen('256') or return; for (@_) { _shawrite($_, length($_) << 3, $state) } _shafinish($state); _sha($state); } push(@EXPORT_OK, 'sha256');` [download] For whatever reason, this works fine, but the generation of the function and export does not. I'll report back if I figure out exactly why this is happening, but for now I am content with having it work with the functions I need hard-coded in.	[reply] [d/l]

It is loading the correct perl module, as that command shows the location I expected. Perhaps it is an issue with my perl build. I don't have a whole lot of options as far as building perl. I am using a target that cannot fit a toolchain on it, so everything needs to be cross-compiled using buildroot. I tried everything I could to build a full version of perl for it, but without any success.	[reply]
