# General Questions
|
|
|
|
## What is this?
|
|
|
|
This is a rewrite of the host application in pure C using the MinGW toolchain.
|
|
|
|
## Why make this?
|
|
|
|
Several reasons:
|
|
|
|
1. The client is written in C and I would like to unify the project's language
|
|
2. The host is currently hard to build using MinGW and is very Windows specific
|
|
3. The host is a jumbled mess of code from all the experimentation going on
|
|
4. I would eventually like to be able to port this to run on Linux guests
|
|
|
|
## When will it be ready?
|
|
|
|
Soon :)
|
|
|
|
## Will it replace the C++ host?
|
|
|
|
Yes, but only when it is feature complete.
|
|
|
|
## Why doesn't this use CMake?
|
|
|
|
It does now...
|
|
~~Because win-builds doesn't distribute it, so to make it easy for everyone to compile we do not require it.~~
|
|
|
|
## How do I build it?
|
|
|
|
#### For Windows on Windows
|
|
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake -G "MSYS Makefiles" ..
|
|
make
|
|
```
|
|
|
|
#### For Linux on Linux
|
|
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
make
|
|
```
|
|
|
|
#### For Windows cross compiling on Linux
|
|
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain-mingw64.cmake ..
|
|
make
|
|
```
|
|
|
|
## Where is the log?
|
|
|
|
It is in your user's temp directory:
|
|
|
|
%TEMP%\looking-glass-host.txt
|
|
|
|
For example:
|
|
|
|
C:\Users\YourUser\AppData\Local\Temp\looking-glass-host.txt
|
|
|
|
You can also open it by simply right clicking the tray icon and selecting "Open Log File"
|
|
|
|
## Why does this version require Administrator privileges
|
|
|
|
This is intentional for several reasons.
|
|
|
|
1. NvFBC requires a system wide hook to correctly obtain the cursor position as NVIDIA decided to not provide this as part of the cursor updates.
|
|
2. NvFBC requires administrator level access to enable the interface in the first place. (WIP)
|
|
3. DXGI performance can be improved if we have this. (WIP)
|
|
|
|
## NvFBC (NVIDIA Frame Buffer Capture)
|
|
|
|
### Why isn't there a build with NvFBC support available.
|
|
|
|
~~Because NVIDIA have decided to put restrictions on the NvFBC API that simply make it incompatible with the GPL/2 licence. Providing a pre-built binary with NvFBC support would violate the EULA I have agreed to in order to access the NVidia Capture SDK.~~
|
|
|
|
Either I miss-read the License Agreement or it has been updated, it is now viable to produce a "derived work" from the capture SDK.
|
|
|
|
> 1.1 License Grant. Subject to the terms of this Agreement, NVIDIA hereby grants you a nonexclusive, non-transferable, worldwide,
|
|
revocable, limited, royalty-free, fully paid-up license during the term of this Agreement to:
|
|
> (i) install, use and reproduce the Licensed Software delivered by NVIDIA plus make modifications and create derivative
|
|
works of the source code and header files delivered by NVIDIA, provided that the software is executed only in hardware products as
|
|
specified by NVIDIA in the accompanying documentation (such as release notes) as supported, to develop, test and service your
|
|
products (each, a “Customer Product”) that are interoperable with supported hardware products. If the NVIDIA documentation is
|
|
silent, the supported hardware consists of certain NVIDIA GPUs; and
|
|
|
|
To be safe we are still not including the NVIDIA headers in the repository, but I am now providing pre-built binaries with NvFBC support included.
|
|
|

|
|
|
|
### Why can't I compile NvFBC support into the host
|
|
|
|
You must download and install the NVidia Capture SDK. Please note that by doing so you will be agreeing to NVIDIA's SDK License agreement.
