# Patch the VST3 SDK and replace all MSVC-isms so it can be compiled with
|
|
# winegcc. We do it this way instead of modifying the SDK directly so we don't
|
|
# have to fork multiple repositories and keep them up to date.
|
|
# If anyone knows a better way to get the SDK to compile with Win32 supports
|
|
# under winegcc without having to modify it then please let me know, because I'd
|
|
# rather not have to do this.
|
|

|

# Usage:
|
|
# patch-vst3-sdk.sh <sdk_directory>
