Jeff Hostetler	dce7d29551	msvc: support building Git using MS Visual C++ With this patch, Git can be built using the Microsoft toolchain, via: make MSVC=1 [DEBUG=1] Third party libraries are built from source using the open source "vcpkg" tool set. See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that we were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

Jonathan Nieder	bc380fca60	mark Windows build scripts executable On Windows the convention is to rely on filename extensions to decide whether a file is executable so Windows users are probably not relying on the executable bit of these scripts, but on other platforms it can be useful documentation.

Ramsay Jones	38743b7d10	msvc: Fix an "unrecognized option" linker warning Having recently added support for building git-imap-send on Windows, we now link against OpenSSL libraries, and the linker issues the following warning: warning LNK4044: unrecognized option '/lssl'; ignored In order to suppress the warning, we change the msvc linker script to translate an '-lssl' parameter to the ssleay32.lib library. Note that the linker script was already including ssleay32.lib (along with libeay32.lib) as part of the translation of the '-lcrypto' library parameter. However, libeay32.dll does not depend on ssleay32.dll and can be used stand-alone, so we remove ssleay32.lib from the '-lcrypto' translation. The dependence of ssleay32.dll on libeay32.dll is represented in the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable. Also, add the corresponding change to the buildsystem generator.

Ramsay Jones	b5d18b8e6f	Fix the exit code of MSVC build scripts on cygwin During an MSVC build on cygwin, the make program did not notice when the compiler or linker exited with an error. This was caused by the scripts exiting with the value returned by system() directly. On POSIX-like systems, such as cygwin, the return value of system() has the exit code of the executed command encoded in the first byte (ie the value is shifted up by 8 bits). This allows the bottom 7 bits to contain the signal number of a terminated process, while the eighth bit indicates whether a core-dump was produced. (A value of -1 indicates that the command failed to execute.) The make program, however, expects the exit code to be encoded in the bottom byte. Futhermore, it apparently masks off and ignores anything in the upper bytes. However, these scripts are (naturally) intended to be used on the windows platform, where we can not assume POSIX-like semantics from a perl implementation (eg ActiveState). So, in general, we can not assume that shifting the return value right by eight will get us the exit code. In order to improve portability, we assume that a zero return from system() indicates success, whereas anything else indicates failure. Since we don't need to know the exact exit code from the compiler or linker, we simply exit with 0 (success) or 1 (failure).

Marius Storm-Olsen	164a5e3faa	Add MSVC to Makefile Enable MSVC builds with GNU Make by simply calling make MSVC=1 (Debug build possible by adding DEBUG=1 as well) Two scripts, clink.pl and lib.pl, are used to convert certain GCC specific command line options into something MSVC understands. By building for MSVC with GNU Make, we can ensure that the MSVC port always follows the latest code, and does not lag behind due to unmaintained NMake Makefile or IDE projects.
