examples/stream does not build

[dkg]

examples/stream/README.md says:

## Building

The `stream` tool depends on SDL2 library to capture audio from the microphone. You can build it like this:

```bash
# Install SDL2
# On Debian based linux distributions:
sudo apt-get install libsdl2-dev

# On Fedora Linux:
sudo dnf install SDL2 SDL2-devel

# Install SDL2 on Mac OS
brew install sdl2

make stream

Ensure you are at the root of the repo when running make stream. Not within the examples/stream dir
as the libraries needed like common-sdl.h are located within examples. Attempting to compile within
examples/steam means your compiler cannot find them and it gives an error it cannot find the file.

whisper.cpp/examples/stream$ make stream
g++     stream.cpp   -o stream
stream.cpp:6:10: fatal error: common/sdl.h: No such file or directory
    6 | #include "common/sdl.h"
      |          ^~~~~~~~~~~~~~
compilation terminated.
make: *** [<builtin>: stream] Error 1

I can confirm that running make stream fails in the way described above. But running from the root of the repo yields:

0 dkg@bob:~/src/whisper/whisper.cpp$ make stream
make: *** No rule to make target 'stream'.  Stop.
2 dkg@bob:~/src/whisper/whisper.cpp$

I had the same issue. Already addressed here and works for me - Link

Try this from the root folder of Whisper
cmake -DWHISPER_SDL2=ON .

I had the same issue. Already addressed here and works for me - Link

Try this from the root folder of Whisper cmake -DWHISPER_SDL2=ON .

i dont understand the steps needed, i too have the same issues, im using windows and git bash, i too have installed SDL2

[dkg]

Thanks for the pointers, @donivpx. What works for me on a debian system with libsdl2-dev installed is, from the repository root:

cmake -B build -DWHISPER_SDL2=ON
(cd build && make stream)

This produces the output binary in build/bin/stream

@Azkazar, Note that just running cmake -DWHISPER_SDL2=ON . will actually rewrite the top-level Makefile, which might not be what you want. If you've already done that, then you might want to git restore Makefile (from the root of the git repo) to undo those changes.

[ggerganov]

I've updated the build instructions for the examples/stream tool:

https://github.com/ggerganov/whisper.cpp/tree/master/examples/stream

@ggerganov @dkg

that doesnt work
