This is the normal standard way in C, C++ as well as Java and there's no
longer any reason for ICU to be different. The various internal macros
providing custom boolean constants can all be deleted and code as well
as documentation can be updated to use lowercase true/false everywhere.
Remove the ICU macros ATOMIC_INT32_T_INITIALIZER and U_INITONCE_INITIALIZER,
which made use of C++ ATOMIC_VAR_INIT, which has been removed from C++20.
With modern C++ features being available, these macros no longer served
any real need.
Change to use the Windows 10 SDK for Win32 (Win7) builds on the VS2019 ADO images.
The Windows 10 SDK is backwards compatible to Windows 7, if WINVER and
_WIN32_WINNT are set before compiling.
Clean up the vcxproj files from VC7.1
This change builds on Vincent Torri's changes.
This installs the ICU DLL files in $prefix/bin instead of $prefix/lib.
Note: In order to disable this change in behavior you can edit
the "mh-mingw*" file(s). If you set the variable MINGW_MOVEDLLSTOBINDIR
to NO instead of YES, then it will retain the previous behavior of
installing the DLLs into the bin folder.
This enables "classic" desktop builds of ICU4C for both ARM (32-bit)
and ARM64 (64-bit) on Windows.
All but the two samples "cal" and "date" in the "allinone" project now
have ARM and ARM64 project configurations, and build for Windows Desktop
ARM/ARM64.
Note: In order to build the ARM/ARM64 data DLL, you need to first build
x64/Release, as the ARM/ARM build uses the x64 bits in order to be able
to cross-compile for ARM/ARM64. This allows for completely building
ARM/ARM64 binaries using only x64 hardware.
The ARM/ARM64 builds require using a newer version of the Windows SDK
than 8.1, so they have a separate WindowsTargetPlatformVersion which
uses Windows 10 SDK version 10.0.16299.0 (aka RS3), which is the first
version of the Windows SDK to support building ARM64 desktop applications.
In addition this also greatly cleans-up the ICU4C ".vcxproj" files, in
order to remove redundant parts, fix inconsistencies, and make them more
readable. This introduces two new variables in the shared `*.props`
files: `IcuBinOutputDir` and `IcuLibOutputDir` in order to further
reduce the amount of duplicated lines in the individual ".vcxproj"
files themselves.
- Use STATIC_NEW for mutex creation, to avoid order-of-destruction problems
by avoiding destruction altogether, while avoiding memory leak reports.
- Remove UConditionVar, replace with direct use of std::condition_variable
Remove the dependencies from the ICU library code on static constructors
that were introduced by using std::mutex and condition variables. The
mutexes are lazily initialized by embedding them as local static variables
in getter functions, and relying on the C++ compiler/runtime to do thread
safe initialization of them.
