cygcc-1.dll: which package?

cygcc-1.dll: which package?

[Brandon Barker]

Hello,

I am trying to provide a binary that will require Cygwin to run. The
trick is, when I compile it on one system and run it on another,
certain dependencies may or may not be present. Although I thought I
did a thorough job on my test system, I'm missing cygcc-1.dll. When I
try to run my executable on a different system than the one it was
compiled on, I get the error:

/cygdrive/c/Users/brand_000/Downloads/WindowsCygwin64_falcon_minDisj_1_0.exe:
error while loading shared libraries: cyggc-1.dll: cannot open shared
object file: No such file or directory

Both systems are using Cygwin64.

At first I thought this was probably libgcc, but it seems to not be
the case since I explicitly checked it, updated it, and got the same
result.

More generally, any advice on dealing with such problems would be appreciated.

Best,
Brandon Barker

When you're wondering what package contains something you're looking for,
consult the package search engine - <http://cygwin.com/packages/>.  It will
tell you if there are any packages in the distro that have the file you're
searching for.  In your case. see:

<http://cygwin.com/cgi-bin2/package-grep.cgi?grep=cyggc-1.dll&arch=x86_64>

And remember, if you're actually distributing a binary, the GPL comes into
play.  You have to provide sources for your app and for the parts of Cygwin
you're distributing.
