fips bgfx

fips-bgfx's Introduction

fips-bgfx

fipsified version of bgfx (https://github.com/bkaradzic/bgfx)

Get fips and clone fips-bgfx:

> mkdir fips-workspace
> cd fips-workspace
> git clone [email protected]:floooh/fips.git
> cd fips
> ./fips clone fips-bgfx
> cd ../fips-bgfx

Build and run on command line:

Build a debug config with xcodebuild (the default build config on OSX):

> ./fips build
> ./fips list targets
> ./fips run 00-helloworld
> ./fips run 01-cubes
...

Nicer command line builds with make or ninja:

# with make:
> ./fips set config osx-make-release
> ./fips build
> ./fips run 00-helloworld
# with ninja:
> ./fips set config osx-ninja-release
> ./fips build
> ./fips run 00-helloworld
...
> ./fips unset config

Work in Xcode:

> ./fips unset config
> ./fips open
[this should open Xcode and load the fips-bgfx project]

Most demos require the current working directory set to fips-bgfx/bgfx/examples/runtime, do this in Xcode by selecting the build target (e.g. 01-cubes), go to 'Edit Scheme... -> Options -> Working Directory'.

See fips-bgfx/fips.yml for the list of demos that require the working directory to be set.

Test for emscripten:

Only one sample currently works on emscripten, '17-drawstress':

# setup emscripten SDK for fips if not done before:
> ./fips setup emscripten
# check if all required tools are there (e.g. python2):
> ./fips diag tools
...
# select emscripten build config, configure, build and run
> ./fips set config emsc-make-release
# enable emscripten FS (FileSystem) module, in ccmake,
# find the FIPS_EMSCRIPTEN_USE_FS option, and set it to ON,
# then press (c)onfigure and (g)enerate:
> ./fips config
...
> ./fips make 17-drawstress
> ./fips run 17-drawstress

Once the browser opens you may have to refresh (F5) if the sample doesn't load immediately.

Known Issues

No Shader Code Generation for DirectX on non-Windows platforms

Shader code generation doesn't work fully because the bgfx shader compiler cannot create HLSL shader on non-windows platforms, the result will mess up the generated xxx.bin.h files checked in the source tree, so it's better to not commit generated files or generate them on windows if there is a need to commit them.

Samples

Some samples does not work on all platforms. Most specifically Emscripten and PNaCL does not support the following samples:

- 13-stencil
- 14-shadowvolumes
- 16-shadowmaps

For missing bx::CtrFileReader or equivalent implementation (see BX_CONFIG_CRT_FILE_READER_WRITER).

fips-bgfx's Issues

Does not compile with latest bgfx

I've been trying to make it work with latest bgfx but without any fortune. I've fixed the compiling of texturec by adding a new iqa lib, but have no idea how to solve the compiling of shaderc, which has a new glslang dependency.

Can't build under macOS

I followed the steps in the README. After building, I get this error message.

"bgfx shaderc not found" in a clean build

I was trying to create a simple project just to try fips and bgfx out.

I get the following error when doing a clean build (fips build in the mytest directory with nothing else in the fips-workspace directory):
"[ERROR] bgfx shaderc executable not found, please run 'make tools' in bgfx directory:"

InitializeBuildStatus:

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
get_filename_component(FIPS_ROOT_DIR "../fips" ABSOLUTE)
include("${FIPS_ROOT_DIR}/cmake/fips.cmake")
fips_setup(PROJECT mytest)
fips_begin_app(foo cmdline)
    fips_src(src)
    fips_deps(bgfx bgfx-examples-common)
fips_end_app()
fips_finish()

src directory simply contains helloworld.cpp and logo.h from the bgfx 00-helloworld example.

This is easily fixed by doing fips build in the fips-bgfx directory, but is it possible to avoid the extra step? (I like the idea of git clone, fips build, done.)

Running the samples with proper cwd doesn't work any longer

I'm not able to run the samples on OSX, even with manually set current working dir from Xcode, any idea what's up with that @fungos ?

PS: samples that need to load files that is... others work fine...

I also get a compile error on Windows in the samples in examples/common/entry/dbg.cpp, may be the current version of bgfx is a bit unstable...
