libquicktime: error: implicitly declaring library function 'memcpy' with type 'void *(void *, const void *, unsigned long)'

Here's the console output:

This is what I can see from the log:

Sure, we can fix the implicit declaration of function error. There are several other open issues about this port that may still exist after we fix this issue.

Hi,

Please note, besides 'memcpy', there is another compilation error in the log that I have posted:

error: implicitly declaring library function 'strcasecmp' with type 'int (const char *, const char *)' [-Werror,-Wimplicit-function-declaration].

Noted about other open issues that may cause failures with this port. Thanks for letting me know.

In a26d95cea0a89c4dc1a3b73f536e2aa502d16c46/macports-ports (master):

libquicktime: Fix implicit declaration of functions

Closes: #63014

Port still doesn't build though. See other tickets.

[ryandesign (Ryan Carsten Schmidt)]

Since this still doesn't build, use the libquicktime-devel port for now.
