# vcpkg_acquire_msys
|
|
|
|
The latest version of this document lives in the [vcpkg repo](https://github.com/Microsoft/vcpkg/blob/master/docs/maintainers/vcpkg_acquire_msys.md).
|
|
|
|
Download and prepare an MSYS2 instance.
|
|
|
|
## Usage
|
|
```cmake
|
|
vcpkg_acquire_msys(<MSYS_ROOT_VAR>
|
|
PACKAGES <package>...
|
|
[NO_DEFAULT_PACKAGES]
|
|
[DIRECT_PACKAGES <URL> <SHA512> <URL> <SHA512> ...]
|
|
)
|
|
```
|
|
|
|
## Parameters
|
|
### MSYS_ROOT_VAR
|
|
An out-variable that will be set to the path to MSYS2.
|
|
|
|
### PACKAGES
|
|
A list of packages to acquire in msys.
|
|
|
|
To ensure a package is available: `vcpkg_acquire_msys(MSYS_ROOT PACKAGES make automake1.16)`
|
|
|
|
### NO_DEFAULT_PACKAGES
|
|
Exclude the normal base packages.
|
|
|
|
The list of base packages includes: bash, coreutils, sed, grep, gawk, gzip, diffutils, make, and pkg-config
|
|
|
|
### DIRECT_PACKAGES
|
|
A list of URL/SHA512 pairs to acquire in msys.
|
|
|
|
This parameter can be used by a port to privately extend the list of msys packages to be acquired.
|
|
The URLs can be found on the msys2 website[1] and should be a direct archive link:
|
|
|
|
https://repo.msys2.org/mingw/i686/mingw-w64-i686-gettext-0.19.8.1-9-any.pkg.tar.zst
|
|
|
|

|
|
|
|
## Notes
|
|
A call to `vcpkg_acquire_msys` will usually be followed by a call to `bash.exe`:
|
|
```cmake
|
|
vcpkg_acquire_msys(MSYS_ROOT)
|
|
set(BASH ${MSYS_ROOT}/usr/bin/bash.exe)
|
|
|
|
vcpkg_execute_required_process(
|
|
COMMAND ${BASH} --noprofile --norc "${CMAKE_CURRENT_LIST_DIR}\\build.sh"
|
|
WORKING_DIRECTORY ${CURRENT_BUILDTREES_DIR}/${TARGET_TRIPLET}-rel
|
|
LOGNAME build-${TARGET_TRIPLET}-rel
|
|
)
|
|
```
|
