In combination with the +interface version identifiers from /include/openvr.h which are baked +into applications at the time they are built, the OpenVR API client +binding library captures and conveys to the SteamVR runtime the version +of the OpenVR API interface behavior that the application expects. + +Applications carry with them a private/local copy of the client binding +library when they ship, and they should install it locally to their +application. Applications should not install the client binding library +globally or attempt to link to a globally installed client binding library. +Doing so negates at least part of the ability for the client binding library +to accurately reflect the version of the OpenVR API that the application +was built against, and so hinders compatibility support in the face of +API changes. + +Most applications should simply link to and redistribute with their application +the pre-built client binding library found in the /bin directory of this +repository. Some small number of applications which have specific requirements +around redistributing only binaries they build themselves should build +the client library from this source and either statically link it into +their application or redistribute the binary they build. + +This is a cmake project, to build it use the version of cmake appropriate +for your platform. For example, to build on a POSIX system simply perform + + cd src; mkdir _build; cd _build; cmake ..; make + +and you will end up with the static library /src/bin/<arch>/libopenvr_api.a + +To build a shared library, pass -DBUILD_SHARED=1 to cmake. +To build as a framework on apple platforms, pass -DBUILD_FRAMEWORK=1 to cmake. +To see a complete list of configurable build options, use `cmake -LAH` diff --git a/gfx/vr/service/openvr/src/dirtools_public.cpp b/gfx/vr/service/openvr/src/dirtools_public.cpp new file mode 100644 index 0000000000..e5cfc02e0c --- /dev/null +++ b/gfx/vr/service/openvr/src/dirtools_public.cpp @@ -0,0 +1,101 @@ +//========= Copyright Valve Corporation ============// +#include "dirtools_public.h" +#include "strtools_public.h" +#include "pathtools_public.h" + +#include <errno.h> +#include <string.h> + +#ifdef _WIN32 +#include "windows.h" +#else +#include <stdlib.h> +#include <stdio.h> +#include <sys/stat.h> +#include <sys/types.h> +#endif + +#if defined( OSX ) +#include <sys/syslimits.h> +#endif + + +//----------------------------------------------------------------------------- +// Purpose: utility function to create dirs & subdirs +//----------------------------------------------------------------------------- +bool BCreateDirectoryRecursive( const char *pchPath ) +{ + // Does it already exist? + if ( Path_IsDirectory( pchPath ) ) + return true;
