ClamAV for Win32 ---------------- 0- Requirements To build the source code you will need: - Git for windows with a git "shell" - Microsoft Visual Studio 2010: the express version builds the 32bit target just fine but it requires a decent amount of fiddling in order to compile the 64bit target; this configuration is therefore not supported. To run the binaries at least Windows 2000 is required. 1- Getting the code The win32 source code is merged in the ClamAV repository and is available via git. Clone the repository with: git clone git://git.clamav.net/git/clamav-devel See http://www.clamav.net/download/sources for more info. 2- Code configuration After downloading the source code, minimal configuration is required: just run the win32/configure.bat script *from within the git shell*. Skip this step if you are building from an official release tarball. 3- Compilation Open win32/ClamAV.sln in Visual Studio and build all. The output directory for the binaries is either /win32/(Win32|x64)/Debug or /win32/(Win32|x64)/Release depending on the configuration you pick. Note: at the time of writing Batch Build is broken in VS10: https://connect.microsoft.com/VisualStudio/feedback/details/556158 Use MSBuild instead 4- Special notes The ClamAV tools in win32 are the same as in unix, so refer to their respective manpage for general usage. The major differences are listed below: - Config files path search order: 1- The content of the registry key "HKEY_LOCAL_MACHINE/Software/ClamAV/ConfDir" 2- The directory where libclamav.dll is located 3- "C:\ClamAV" - Database files path search order: 1- The content of the registry key "HKEY_LOCAL_MACHINE/Software/ClamAV/DataDir" 2- The directory "database" inside the directory where libclamav.dll is located 3- "C:\ClamAV\db" - Globbing Since the windows command prompt doesn't take care of wildcard expansion, minimal emulation of unix glob() is performed internally. It supports "*" and "?" only. - File paths Please always use the backslash as the path separator. SMB Network shares and UNC paths are supported. - Debug builds Malloc in debug (as opposed to release) mode fails after allocating some 90k chunks; such builds won't be able to handle large databases. Just do yourself a favour and always build in release mode. 5- Special thanks Special thanks to Gianluigi Tiesi and Mark Pizzolato for their valuable help in coding and testing.
