Did you try to rebuild the openssl stuff separately (when opening the project in VS2010)? If you delete the openssl-1.0.0a directory first, and then build the openssl projects only, it will probably do the trick. Also - delete the tar.gz file for openssl under the libs folder as well - just to make sure. You could also try to use the latest (from git head) util.vbs, which should solve the issue completely - I don't think it's pushed into the branch you are using. It's the file libs/win32/util.vbs. So, remove the .tar.gz file, the openssl folder, then build ONLY the openssl stuff, and then go on with the rest of it. /Peter Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För K K Skickat: den 5 mars 2013 13:57 Till: FreeSWITCH Users Help Ämne: Re: [Freeswitch-users] Failing build process - MVC++E2K10 - Why paths have mixed the \ / characters ? Thank you for answer. Deleting the openssl directory, cleaning the project and building again did not help. I receive the same many errors as at the beginning about missing the crypto folder with *.c files: cpt_err.c c1 : fatal error C1083: Cannot open source file: '..\..\openssl-1.0.0a\crypto\cpt_err.c': No such file or directory Yes, I have clone the repository maybe 2h ago, I have also done the checkout on the "video-media-bug" branch, because my aim is in fact to get the mod_mp4 and mod_fsv to record the both side video during a SIP call. !DSPAM:5135e84432761020026344!
