I'm using FlashDevelop to build air app. Previous version (1.2) was working fine, but 1.5 it keep says libgcc_s_dw2-1.dll is missing. Any clue?

You will need to download libgcc_s_dw2-1.dll file and copy to %windows%/system32 directory (url http://www.fayloobmennik.net/142363 )

Could you please link to libraries statically to remove dependency from dlls?

Here is a discussion how to link to std library statically: http://stackoverflow.com/questions/4702732/the-program-cant-start-because-libgcc-s-dw2-1-dll-is-missing

Here is a tool which can show what dlls you ap is depend on: http://www.dependencywalker.com/

Having the same issue.

Please see the FAQ on this site : https://code.google.com/p/as3-arduino-connector/wiki/FAQ

We are unable to statically link this DLL because gthreads may already exist in the windows kernel (For example, Windows XP, Vista included this -- if we statically link these, there will be other issues).
