Hello out there, I have installed Visual C++ 2008 Express edition on my Windows 7 machine. I downloads the freeswitch-1-0-6-tar-gz file from http://files.freeswitch.org. I extract the source code and opens the project in Visual C++. Then I press F7 to start compilation. Numerous errors are returned: At the end of compilation: 120>LINK : fatal error LNK1181: cannot open input file '..\..\..\..\libs\win32\sofia\debug\libsofia_sip_ua_static.lib' 120>Build log was saved at "file://c:\R&D\FreeSwitch\freeswitch-1.0.6\src\mod\endpoints\mod_sofia\Win32 \Debug\BuildLog.htm" 120>mod_sofia - 1 error(s), 12 warning(s) ========== Rebuild All: 102 succeeded, 17 failed, 11 skipped ========== I investigate the errors and find among several the below errors: 13>c1 : fatal error C1083: Cannot open source file: '..\..\pthreads-w32-2-7-0-release\pthread.c': No such file or directory 13>Build log was saved at "file://c:\R&D\FreeSwitch\freeswitch-1.0.6\libs\win32\pthread\Debug DLL\BuildLog.htm" 13>pthread - 1 error(s), 0 warning(s) 14>Deleting intermediate and output files for project 'make_modem_filter', configuration 'All|Win32' 14>make_modem_filter : error PRJ0008 : Could not delete file 'c:\R&D\FreeSwitch\freeswitch-1.0.6\libs\spandsp\src\msvc\All\RSP0001D534166 324.rsp'. 14>Make sure that the file is not open by another process and is not write-protected. 14>make_modem_filter - 1 error(s), 0 warning(s) 19>agc.c 19>c1 : fatal error C1083: Cannot open source file: '..\..\sphinxbase-0.4.99\src\libsphinxbase\feat\agc.c': No such file or directory 19>bio.c Anyone knows what I miss to do.
