MSYS2 target support (cossacklabs#469)
* MSYS2 target support
MSYS2 is a popular and easy way to compile POSIX-compliant software on
Windows. It provides GNU development environment and API compatibility
layer between POSIX and WinAPI. All of this allows us to use the same
build system and code as is, with the toolchain automagically producing
PE binaries useable on Windows.
However, we need to introduce a number of changes to the build system
to support MSYS:
- Detect MSYS environment and provide "IS_MSYS" variable for checks
This allows us to introduce MSYS-specific behavior in Makefile.
- Build Windows DLLs for shared objects
First of all, use MSYS naming scheme for dynamically loaded libraries:
"msys-${library_name}-${abi_version}.dll". These will contain the code
loaded by applications.
After that we need to produce "import libraries" which are necessary
in Windows world to link against dynamic libraries. On MSYS they are
named "lib${library_name}.dll.a".
Regular static libraries are still named "lib${library_name}.a". These
are useable only for inside MSYS2.
- Install libraries to correct paths
On MSYS shared libraries have to be installed to "/usr/bin" because of
the way library loading works in Windows: libraries need to be placed
next to executables.
DLLs do not need symlinks on MSYS. However, they need import libraries
instead. Update the installation targets to do this correctly.
Update uninstallation targets as well.
- Avoid duplicate slashes when usign DESTDIR
Remove slashes between DESTDIR and paths. Windows does not normalize
duplicate slashes under MSYS which leads to really weird issues when
creating directories.
- Place tests into the same directory as libraries
We need to do this because tests link against libraries dynamically,
they need to be able to load the library from the build directory
(as it's not yet installed). Windows does not have a direct analog
of RPATH (as on Linux), and does not record library paths (as macOS
does). We can use LD_LIBRARY_PATH for running tests, but that would
make them hard to use without our makefile. Therefore just change
the location.
Also, the NIST test suite has a bit different name on Windows. Add it to
the .gitignore list.
With this, installation on MSYS can be done like this:
make install
GGEZ!
(Note that MSYS does not have /usr/local in its default search paths.
You'll need to use -L/usr/local/lib when building applications, and
add /usr/local/bin to PATH when running them. Or just install with
PREFIX=/usr)
* Packaging for MSYS2 (and pacman)
Provide a PKGBUILD file which can be used to build Themis package for
MSYS2. A similar file could be used for building on ArchLinux. However,
this one does not work as is on Linux due to differences in dependency
naming and directory layout.
Themis is a library. It is customary in MSYS2 to provide Debian-style
split packages for libraries:
- "themis" contains runtime shared libraries: *.dll on Windows
- "themis-devel" contains headers, static libraries, and pkg-config
files which are required for building software that uses Themis
The packages may be built by running
makepkg -p PKGBUILD.MSYS2
in the directory with the PKGBUILD file, then you install them with
pacman -U themis-0.11.2-1-x86_64.tar.xz
pacman -U themis-devel-0.11.2-1-x86_64.tar.xz
makepkg always downloads pristine source tarball, so there is no point
in adding a Makefile target for preparing a package from source code.- Loading branch information
