# Yammer
|
|
|
|
|
Audio visualizer thing in guile scheme
|
|
|
|
|
|
|
|
|
|
# Build
|
|
|
|
|
## Dependencies
|
|
|
|
|
`guile-sdl2`, `fftw`
|
|
|
|
|
|
|
|
|
|
## Compiling the library
|
|
|
|
|
You need to compile the yammer.c file because it has wrappers around fftw functions.
|
|
|
|
|
```sh
|
|
|
|
|
gcc -shared yammer.c -o libyammer.so -Wall -Wextra -Werror -fPIC -shared -lfftw3 -lm -O3 -ggdb
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
# Configuration
