| − | * Microsoft Visual Studio [https://www.visualstudio.com/vs/older-downloads/ 2017] or [http://www.visualstudio.com/downloads/download-visual-studio-vs 2019]
| |
| − | * in 2020 still most our developers use VS2017, so you are going to have less problems with it as its more widely used and more maintained.
| |
| − | * Git or git GUI, for example, SourceTree [http://www.sourcetreeapp.com/download download]
| |
| − | * CMake [https://cmake.org/download/ download]. During install after accepting license agreement make sure to check "Add CMake to the system PATH for all users".

| − | = Choose directory =
| |
| − | | |
| − | Create a directory for VCMI development, eg. '''C:\VCMI'''
| |
| − | We will call this directory as '''[VCMI_DIR]'''
| |
| − | | |
| − | '''Warning!''' Replace '''[VCMI_DIR]''' with path you chosen in following commands of this instruction.
| |
| − | | |
| − | == How to choose good directory ==
| |
| − | | |
| − | It is recommended to avoid non-ascii characters in the path to your working folders. The folder should not be write-protected by system.
| |
| − | Good location:
| |
| − | * '''C:\VCMI'''
| |
| − | Bad locations:
| |
| − | * '''C:\Users\Michał\VCMI''' (non-ascii character)
| |
| − | * '''C:\Program Files (x86)\VCMI''' (write protection)

| − | = Install dependencies =
| |
| − | | |
| − | You have two options: to use pre-built libraries or build your own. We strongly recommend start with using pre-built ones.
| |
| − | | |
| − | == Option A. Use pre-built Vcpkg ==
| |
| − | So you decide to start using Vcpkg packages pre-built by VCMI team.
| |
| − | | |
| − | Package guaranteed to work since they tested with every commit by [https://ci.appveyor.com/project/vcmi/vcmi AppVeyor]
| |
| − | * Please note that as of 2020, this lib wasnt yet updated for vs2019, so for vs2019 you will probaby have to use option B.

| |
| − | cpack
| |
| − | </pre>
| |
| − | === If you built for Debug: ===
| |
| − | <pre>
| |
| − | cpack -C Debug

| − | = Troubleshooting and workarounds =
| |
| − | Vcpkg might be very unstable due to limited popularity and fact of using bleeding edge packages (such as most recent Boost). Using latest version of dependencies could also expose both problems in VCMI code or library interface changes that developers not checked yet. So if you're built Vcpkg yourself and can't get it working please try to use binary package.
| |
| − | | |
| − | Pre-built version we provide is always manually tested with all supported versions of MSVC for both Release and Debug builds and all known quirks are listed below.
| |
| − | | |
| − | === Debug build of VCMI won't run since SDL2.dll / libbz2.dll missing ===
| |
| − | | |
| − | Almost all of Vcpkg debug libraries are built with "d" prefix, but for whatever reason VCMI or some libraries might expect them to be named without prefix. Workaround is to just make a copy of said library with different name.
| |
| − | | |
| − | Likely this can be resolved by some CMake configuration magic so if you know how please make pull request.
| |
| − | | |
| − | === I got crash within library XYZ.dll ===
| |
| − | | |
| − | Good workaround is to use debug version of said library instead of release one or vice versa. If that's helped you can swap the library within Vcpkg package itself so you don't need to do it every time when you.
| |
| − | | |
| − | === Debug build is very slow ===
| |
| − | | |
| − | Debug builds with MSVC are generally extremely slow since it's not just VCMI binaries are built as debug, but every single dependency too and this usually mean no optimizations at all. Debug information that available for release builds is often sufficient so just avoid full debug builds unless absolutely necessary.
