What exactly do you mean "fresh clone"? Last time I build this solution without any problems was two weeks ago. Yesterday I did "Clean Solution" and build.Got a lot of fatal errors. I applied "Rebuild Solution", got the same result. Today I've pulled latest git "c9a49b0", I've removed solution files and pulled them from git repository back, I've run "git status" to make sure that I have latest and correct sources. I've repeated "Clean Solution" again and build it twice to get this bottom line: ========== Build: 21 succeeded, 72 failed, 53 up-to-date, 18 skipped ========== The only thing I do with solution properties configuration is I turn off project "mod_managed", Debug_CLR configuration, Win32 platform, because I always getting errors building it. The rest is default. And, as I said, I build it successfully for years. But now (actually a week ago or so) something becomes suddenly wrong and I'm getting lot of fatal errors... The first fatal error is this: LINK : fatal error LNK1181: cannot open input file 'C:\Dev\FS\Win32\Debug\FreeSwitchCore.lib' It's because when VS tried to make FreeSwitchCoreLib, it failed: ------ Build started: Project: FreeSwitchCoreLib, Configuration: Debug Win32 ------ Generating switch_version.inc Checking if we're building a newer git version switch_rtp.c ..\..\src\switch_rtp.c(2270): error C2220: warning treated as error - no 'object' file generated ..\..\src\switch_rtp.c(2270): warning C4013: 'SSL_CTX_set_tlsext_use_srtp' undefined; assuming extern returning int ------ Build started: Project: iksemel, Configuration: Debug Win32 ------ ... -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Build-errors-in-2010-express-s...
