Open
Description
I'm trying to create a wrapper around OpenVDB C++ library. OpenVDB is a volume data file format used in blockbuster visual effects.
There is a repo with instructions to replicate on macOS. The panic happens pretty late during binding generation.
Bindgen Invocation
let openvdb_bindings = bindgen::Builder::default()
.header("wrapper.hpp")
.clang_arg("-std=c++11")
.clang_arg(format!("-I/{}", open_vdb.join("include").display()))
.clang_arg("-I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreFoundation.framework/Versions/A/Headers/")
.clang_arg("-I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreServices.framework/Versions/A/Headers/")
.clang_arg("-I/Library/Developer/CommandLineTools/usr/include/c++/v1/")
.clang_arg("-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/")
.clang_arg("-F/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/")
.generate()
.expect("Unable to generate OpenVDB bindings.");Actual Results
