+1. Visual Studio 2013 is no longer supported
+
+ [As scheduled](https://github.com/KhronosGroup/glslang/blob/9eef54b2513ca6b40b47b07d24f453848b65c0df/README.md#planned-deprecationsremovals),
+Microsoft Visual Studio 2013 is no longer officially supported. \
+ Please upgrade to at least Visual Studio 2015.
+
+2. The versioning scheme is being improved, and you might notice some differences. This is currently WIP, but will be coming soon. See, for example, PR #2277.
-## Planned Deprecations/Removals
+3. If you get a new **compilation error due to a missing header**, it might be caused by this planned removal:
-1. **SPIRV Folder, 1-May, 2020.** Glslang, when installed through CMake,
+**SPIRV Folder, 1-May, 2020.** Glslang, when installed through CMake,
will install a `SPIRV` folder into `${CMAKE_INSTALL_INCLUDEDIR}`.
This `SPIRV` folder is being moved to `glslang/SPIRV`.
During the transition the `SPIRV` folder will be installed into both locations.
The old install of `SPIRV/` will be removed as a CMake install target no sooner than May 1, 2020.
See issue #1964.
-2. **Visual Studio 2013, 20-July, 2020.** Keeping code compiling for MS Visual Studio 2013 will no longer be
-a goal as of July 20, 2020, the fifth anniversary of the release of Visual Studio 2015.
+If people are only using this location to get spirv.hpp, I recommend they get that from [SPIRV-Headers](https://github.com/KhronosGroup/SPIRV-Headers) instead.

# Glslang Components and Status
The following steps assume a Bash shell. On Windows, that could be the Git Bash
shell or some other shell of your choosing.
-#### 1) Check-Out this project
+#### 1) Check-Out this project
```bash
cd <parent of where you want glslang to be>
# "Release" (for CMAKE_BUILD_TYPE) could also be "Debug" or "RelWithDebInfo"
```
+For building on Android:
+```bash
+cmake $SOURCE_DIR -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$(pwd)/install" -DANDROID_ABI=arm64-v8a -DCMAKE_BUILD_TYPE=Release -DANDROID_STL=c++_static -DANDROID_PLATFORM=android-24 -DCMAKE_SYSTEM_NAME=Android -DANDROID_TOOLCHAIN=clang -DANDROID_ARM_MODE=arm -DCMAKE_MAKE_PROGRAM=$ANDROID_NDK_ROOT/prebuilt/linux-x86_64/bin/make -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK_ROOT/build/cmake/android.toolchain.cmake
+# If on Windows will be -DCMAKE_MAKE_PROGRAM=%ANDROID_NDK_ROOT%\prebuilt\windows-x86_64\bin\make.exe
+# -G is needed for building on Windows
+# -DANDROID_ABI can also be armeabi-v7a for 32 bit

For building on Windows:

the web grammar subset (see more about the web subset in the next section).
### Building to WASM for the Web and Node
+### Building a standalone JS/WASM library for the Web and Node
Use the steps in [Build Steps](#build-steps), with the following notes/exceptions:
-* For building the web subset of core glslang:
- + execute `updateGrammar web` from the glslang subdirectory
- (or if using your own scripts, `m4` needs a `-DGLSLANG_WEB` argument)
- + set `-DENABLE_HLSL=OFF -DBUILD_TESTING=OFF -DENABLE_OPT=OFF -DINSTALL_GTEST=OFF`
- + turn on `-DENABLE_GLSLANG_JS=ON`
- + optionally, for a minimum-size binary, turn on `-DENABLE_GLSLANG_WEBMIN=ON`
- + optionally, for GLSL compilation error messages, turn on `-DENABLE_GLSLANG_WEB_DEVEL=ON`
* `emsdk` needs to be present in your executable search path, *PATH* for
- Bash-like environments

+ Bash-like environments:
+ + [Instructions located here](https://emscripten.org/docs/getting_started/downloads.html#sdk-download-and-install)
* Wrap cmake call: `emcmake cmake`
+* Set `-DBUILD_TESTING=OFF -DENABLE_OPT=OFF -DINSTALL_GTEST=OFF`.
+* Set `-DENABLE_HLSL=OFF` if HLSL is not needed.
+* For a standalone JS/WASM library, turn on `-DENABLE_GLSLANG_JS=ON`.
+* For building a minimum-size web subset of core glslang:
+ + turn on `-DENABLE_GLSLANG_WEBMIN=ON` (disables HLSL)
+ + execute `updateGrammar web` from the glslang subdirectory
+ (or if using your own scripts, `m4` needs a `-DGLSLANG_WEB` argument)
+ + optionally, for GLSL compilation error messages, turn on
+ `-DENABLE_GLSLANG_WEBMIN_DEVEL=ON`
* To get a fully minimized build, make sure to use `brotli` to compress the .js
and .wasm files
Example:
```sh
-emcmake cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GLSLANG_WEB=ON \
+emcmake cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GLSLANG_JS=ON \
-DENABLE_HLSL=OFF -DBUILD_TESTING=OFF -DENABLE_OPT=OFF -DINSTALL_GTEST=OFF ..
