Bug 5082

Summary: [Build Failure] using master + cmake
Product: SDL Reporter: stephane
Component: *don't know*Assignee: Ryan C. Gordon <icculus>
Status: WAITING --- QA Contact: Sam Lantinga <slouken>
Severity: critical    
Priority: P2    
Version: HG 2.1   
Hardware: x86_64   
OS: Windows 10   

Description stephane 2020-04-10 18:31:24 UTC 
Building The SDL on master failes ith the error :
```
src\sensor\SDL_sensor.c(48): error C2059: syntax error: '}' 
src\sensor\SDL_sensor.c(88): warning C4034: sizeof returns 0 
src\sensor\SDL_sensor.c(104): warning C4034: sizeof returns 0 
```

and lots of these also

We've also noticed build failure using vcpkg --head on linux. don't know if this is related but it really seems to be a linkage failure (linking statically, working on non-head vcpkg) :
```
src/audio/sndio/SDL_sndioaudio.c:95: undefined reference to `sio_open'
src/audio/sndio/SDL_sndioaudio.c:96: undefined reference to `sio_close'
src/ase-2.0.10-c1be3add38/src/audio/sndio/SDL_sndioaudio.c:97: undefined reference to `sio_setpar'
src/ase-2.0.10-c1be3add38/src/audio/sndio/SDL_sndioaudio.c:98: undefined reference to `sio_getpar'

and lots of these also

It seems odd that sndio would be enabled on Windows builds? What build system are you using?

Can you try the latest code and see if the sensor build issue has been fixed?

Hi ! 
Well, the sndio stuff happens only on linux

On windows, using w10 MSVC 2017
On linux, using Ubuntu 18.04 + vcpkg

Windows build still failing :

\SDL-mirror\src\sensor\windows\SDL_windowssensor.c(44): error C2374: 'SENSOR_DATA_TYPE_ANGULAR_VELOCITY_X_DEGREES_PER_SECOND': redefinition; multiple initialization \SDL-mirror\build\SDL2-static.vcxproj]

Seems some symbol are already defined.

Sorry, forgot to mention the build is done with latest master
