Don't know what the rules are about replying to yourself around here, but I made some progress on the issue and thought it would be useful to share. There are two problems that seem to cause tcpreplay to have trouble building under cygwin64. The first is that the winpcap dev libraries are distributed without 64-bit .a files; the second is that the ./configure script is looking for the libraries in the wrong place. (1) If you look under /wpdpack/lib you'll notice that both .lib and .a files are distributed for winpcap. If you look under /wpdpack/lib/x64 you'll notice only .lib files are distributed. I found a post on the MinGW-w64 mailing list* that describes how to generate the .a files from the .lib files. The commands are: (a) gendef wpcap.dll (b) dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libwpcap.a --input-def wpcap.def I used the .dll's in the c:\windows\SysWOW64 folder to do this. This should be done both for libpacket.a and libwpcap.a. (2) Once the .a files are built and copied to the correct location, you still have issues because ./configure is looking for the .a files in /wpdpack/lib and not /wpdpack/lib/x64. I just copied the 64-bit version from /wpdpack/lib/x64 to /wpdpack/lib. After the above two steps, ./configure and make successfully ran. Unfortunately, tons of tests are failing. All the [tcpprep] tests failed with core dumps. The first six [tcpreplay] tests passed, but the Multipler test is stuck in an infinite loop. I don't know exactly where to go from here; but I suspect the conversation should probably move to the dev list if it continues. Personally, I'm just going to move back to good old 32-bit cygwin and hope to revisit this in the future. *http://sourceforge.net/p/mingw-w64/discussion/723797/thread/530727b3 ------------------------------------------------------------------------------ Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.
