Setting Scripts
---------------

@@ Replace this section with a proper package build/install instructions when
   the package name is finalized.

@@ Interestingly INSTALL files for our packages provide instuctions how to
   build the package but not how to install it.

The "driver" scripts that you will be invoking have names in the following
form:

<tool>-<version>-<target>

Where:

<tool>     is one of 'cl' 'link' 'lib' 'mt' 'rc'
<version>  is the Visual Studio version, for example, 11, 12, 14u2, 15rc1
<target>   is the compiler target, for example, 32 (x86), 64 (x86_64).

There are also the "configuration" scripts, msvc-NN/msvc-<version>-<target>,
which provide the Visual Studio/SDK location and configuration (in a way
similar to vcvars32.bat). There is also a bunch of other helper scripts that
you will not need to modify or invoke directly. It is also required to build
msvc-filter native utility using build2.

All of these scripts and utilities should reside in the same directory. In
particular, you cannot copy, say, cl-<...> to /usr/local/bin/ while leaving
the rest in some other directory -- this will not work. What you can do,
however, is create symlinks to the driver scripts in /usr/local/bin/ -- this
will work.

If you only need to make the scripts usable by a single user, then the easiest
approach is to add the script's directory to your PATH in, say, .bashrc, for
example:

export PATH=$HOME/msvc-linux:$PATH

Alternatively, if you have something like ~/bin/ that is already in PATH, then
you can simply add symlinks to the scripts there. This way you can also choose
shorter tool names, for example:

for t in cl link lib mt rc; do \
  ln -s .../msvc-linux/$t-14u2-64 ~/bin/$t-14; done

While you can modify the configuration scripts, retainig such modifications
over updates will be tedious. As a result, there are several environment
variables that you can set (e.g., in your .bashrc) to adjust some of the
common configuration values.

Currently you can override WINEPREFIX and INSTALLDIR via the following
environment variable hierarchy (from highest to lowest precedence):

MSVC_<MAJOR><MINOR>_*   # MSVC_14U2_INSTALLDIR
MSVC_<MAJOR>_*          # MSVC_14_INSTALLDIR
MSVC_*                  # MSVC_INSTALLDIR

The WINEPREFIX value corresponds to the WINEPREFIX Wine environment variable
that allows one to use an alternative (to ~/.wine) root directory. You can
use it, for example, to maintain multiple Visual Studio updates (e.g., 14u1,
14u2, 14u3) which otherwise cannot coexist in a single installation.

The INSTALLDIR directory can be used to alter the Visual Studio installation
directory name (not path; the default is "Microsoft Visual Studio NN.0").
This can be used, for example, to implement an alternative multiple updates
strategy by installing them in the same Wine root but in different
directories. For details on how this value is used refer to the configuration
scripts.


Install Wine
------------

You need 1.7.55 or later. Previous versions are known not to work with Visual
Studio 14.

For Ubuntu, to install stable:

# add-apt-repository ppa:ubuntu-wine/ppa
# apt-get update
# apt-get install --no-install-recommends winbind
# apt-get install wine1.7
# apt-get install p11-kit-modules:i386 libp11-kit-gnome-keyring:i386

For Ubuntu, to install staging (into /opt/):

# add-apt-repository ppa:wine/wine-builds
# apt-get update
# apt-get install --install-recommends wine-staging

To install compatibility symlinks:

# apt-get install winehq-staging


Configure Wine
--------------

$ winecfg

If it suggests installing some stuff (Gecko, Mono), refuse. Change the
platform to Windows 7 (later version will probably also work).

64-bit link.exe from Visual Studio 14 is known not to work with Mono that
may have (still) been installed by winecfg. To remove it, run:

$ wine64 uninstaller --remove '{E45D8920-A758-4088-B6C6-31DBB276992E}'


Prepare to Copy Visual Studio
-----------------------------

Note that below we assume that you have installed Visual Studio in the default
location.

The following instructions are for mounting the VM parition on Linux host.
However, simply archiving the required directories on the running VM and
copying them to the Linux host should work as well.

Mount the VM disk (make sure it is not running) where you installed Visual
Studio. First get the second partition offset (<O>) and sector size (normally
512, as below).

# fdisk -lu .../windows-7.img

Then mount via the loopback device:

# losetup -o $((512*<O>)) /dev/loop0 ./windows-7.img
# mount -o ro /dev/loop0 /mnt

When finished copying Visual Studio, unmount and delete the loopback:

# umount /mnt
# losetup -d /dev/loop0


Copy and Setup Visual Studio 11
-------------------------------

$ mkdir -p ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 11.0"
$ cp -r "/mnt/Program Files (x86)/Microsoft Visual Studio 11.0/VC" \
  ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 11.0/"
$ cp "/mnt/Program Files (x86)/Microsoft Visual Studio 11.0/Common7/IDE/mspdb110.dll" \
  ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 11.0/VC/bin/"

$ mkdir -p ".wine/drive_c/Program Files (x86)/Windows Kits"
$ cp -r "/mnt/Program Files (x86)/Windows Kits/8.0" \
  ".wine/drive_c/Program Files (x86)/Windows Kits/"

Add lower-case symlinks for upper-case named headers:

$ etc/lowercase-headers \
  ".wine/drive_c/Program Files (x86)/Windows Kits/8.0/Include"

Run the VC11 redistributable DLLs installer for both x64 and x86 from
.../VC/redist/1033/.

Add overrides for msvcr110.dll and msvcp110.dll: run winecfg, select the
"Libraries" tab, then enter the DLL name and "Add".


Copy and Setup Visual Studio 12
-------------------------------

$ mkdir -p ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 12.0"
$ cp -r "/mnt/Program Files (x86)/Microsoft Visual Studio 12.0/VC" \
  ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 12.0/"

$ mkdir -p ".wine/drive_c/Program Files (x86)/Windows Kits"
$ cp -r "/mnt/Program Files (x86)/Windows Kits/8.1" \
  ".wine/drive_c/Program Files (x86)/Windows Kits/"

Add lower-case symlinks for upper-case named headers:

$ etc/lowercase-headers \
  ".wine/drive_c/Program Files (x86)/Windows Kits/8.1/Include"

Run the VC12 redistributable DLLs installer for both x64 and x86 from
.../VC/redist/1033/.

Add overrides for msvcr120.dll and msvcp120.dll: run winecfg, select the
"Libraries" tab, then enter the DLL name and "Add".


Copy and Setup Visual Studio 14
-------------------------------

Note: 14 Update 2 requires Wine 1.9 or later (bug #34851).
Note: 14 Update 2 is known to work with Wine 1.9.7, 1.9.8 but not 1.9.15.

$ mkdir -p ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 14.0"
$ cp -r "/mnt/Program Files (x86)/Microsoft Visual Studio 14.0/VC" \
  ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 14.0/"
$ cp "/mnt/Program Files (x86)/Microsoft Visual Studio 14.0/VC/redist/x86/Microsoft.VC140.CRT/msvcp140.dll" \
  ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/"

Remove Microsoft's "experience improvement data uploade" which crashes:

$ find ".wine/drive_c/Program Files (x86)/Microsoft Visual Studio 14.0/" \
  -name vctip.exe -exec rm -f '{}' ';'

$ mkdir -p ".wine/drive_c/Program Files (x86)/Windows Kits"
$ cp -r "/mnt/Program Files (x86)/Windows Kits/8.1" \
  ".wine/drive_c/Program Files (x86)/Windows Kits/"
$ cp -r "/mnt/Program Files (x86)/Windows Kits/10" \
  ".wine/drive_c/Program Files (x86)/Windows Kits/"

Add lower-case symlinks for upper-case named headers:

$ etc/lowercase-headers \
  ".wine/drive_c/Program Files (x86)/Windows Kits/8.1/Include" \
  ".wine/drive_c/Program Files (x86)/Windows Kits/10/Include"

Installing via the redistributable DLLs still does not work as of Wine 1.7.55.
Instead, we have to manually copy a bunch of DLLs from /mnt/Windows/{SysWoW64/
System32/} to .wine/drive_c/windows/{syswow64/ system32/} and add Wine
overrides (run winecfg, select the "Libraries" tab, then enter the DLL name
and press "Add").

To discover the list of DLLs, run cl-14 to compile and link an executable and
then run the executable itself (see Test below): any DLL that causes an error
needs an override.

For Wine 1.7.55-1.9.8 the list is:

  api-ms-win-crt-runtime-l1-1-0.dll
  api-ms-win-crt-locale-l1-1-0.dll
  api-ms-win-crt-heap-l1-1-0.dll
  api-ms-win-crt-stdio-l1-1-0.dll
  api-ms-win-crt-conio-l1-1-0.dll
  ucrtbase.dll
  vcruntime140.dll
  msvcp140.dll

The following overrides are necessary because of some unimplemented functions:

  api-ms-win-crt-string-l1-1-0.dll
  api-ms-win-crt-time-l1-1-0.dll


Test

cl-<...> /EHsc /MD /TP hello-world.cxx
./hello-world.exe


Usage
=====

To suppress Wine debug messages (especially advisable if running executables
built with more recent Visual Studio versions) you may want to add the
following line to your .bashrc or similar:

export WINEDEBUG=fixme-all


Hacking
=======

To add support for a new Visual Studio version follow this overall plan:


Install Visual Studio
---------------------

Install the new version on a Windows machine keeping the setup as close to
default as possible. Specifically, don't alter the default installation
directory, SDK to use, etc. Normally, you would make sure all the compilers
that you will need are installed (32, 64-bit x86, ARM, etc) and that's it.
Note also that we use the 64-to-32-bit cross-compiler for 32-bit builds.


Come up with Configuration(s)
-----------------------------

By examining the INCLUDE and LIB environment variables in the corresponding
Visual Studio Command Prompts, determine which SDK/CRT versions are used,
executable paths for the tools (use the where command), etc.

Based on this information create the corresponding configuration file(s) in
msvc-NN/ subdirectory. Use the existing configuration from the closest version
as a guide.


Create Driver Scripts
---------------------

Create the driver scripts corresponding to each new configuration. For example
(replace <version> and <target>):

for t in cl link lib mt rc; do \
  cp cl-11-32 $t-<version>-<target>; done


Copy and Setup Visual Studio on Linux
-------------------------------------

Copy the Visual Studio setup over to a Linux machine as discussed above using
instructions from the closest version as a guide. Use the new driver scripts
for testing.

Write down new instructions or update one of the existing.


Update Common Scripts
---------------------

In a new version of Visual Studio the tools may have new options that may need
to be handled in the msvc-common/msvc-<tool>-common scripts. To check if any
were added, take a diff of usage outputs (/? option) from the new version and
the most recent that is already supported.
