Trying to wrap the hurl library in flutter_rust_bridge for a package in flutter #3603

Hi, Seems like there is a linking issue with libxml (uses par Hurl). Could you verify in the logs that the command line builds include |
|
I don't know how it calls the build method but here are the detailed logs for you. |
|
You should search for "how to link with libxml2 with Xcode", I don't know how to analyse these logs... |
#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html.
# Run `pod lib lint hurl.podspec` to validate before publishing.
#
Pod::Spec.new do |s|
s.name = 'hurl'
s.version = '0.0.1'
s.summary = 'A new Flutter FFI plugin project.'
s.description = <<-DESC
A new Flutter FFI plugin project.
DESC
s.homepage = 'http://example.com'
s.license = { :file => '../LICENSE' }
s.author = { 'Your Company' => '[email protected]' }
# This will ensure the source files in Classes/ are included in the native
# builds of apps using this FFI plugin. Podspec does not support relative
# paths, so Classes contains a forwarder C file that relatively imports
# `../src/*` so that the C sources can be shared among all target platforms.
s.source = { :path => '.' }
s.source_files = 'Classes/**/*'
s.dependency 'FlutterMacOS'
s.platform = :osx, '10.11'
s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES' }
s.swift_version = '5.0'
s.script_phase = {
:name => 'Build Rust library',
# First argument is relative path to the `rust` folder, second is name of rust library
:script => 'sh "$PODS_TARGET_SRCROOT/../cargokit/build_pod.sh" ../rust hurl',
:execution_position => :before_compile,
:input_files => ['${BUILT_PRODUCTS_DIR}/cargokit_phony'],
# Let XCode know that the static library referenced in -force_load below is
# created by this build step.
:output_files => ["${BUILT_PRODUCTS_DIR}/libhurl.a"],
}
s.pod_target_xcconfig = {
'DEFINES_MODULE' => 'YES',
# Flutter.framework does not contain a i386 slice.
'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386',
'OTHER_LDFLAGS' => '-force_load ${BUILT_PRODUCTS_DIR}/libhurl.a -lxml2',
}
endNeed to add the -lxml2 in the OTHER_LDFLAGS now it compiles. Attached my podspec file if someone needs it. Thanks @jcamiel for the flag. |

https://crates.io/crates/libxml after banging my head with anything and everything this package doesn't support ios and android as far as I can tell by reading the code. build.rs fn main() {
if let Ok(ref s) = std::env::var("LIBXML2") {
// println!("{:?}", std::env::vars());
// panic!("set libxml2.");
let p = std::path::Path::new(s);
let fname = std::path::Path::new(p.file_name().expect("no file name in LIBXML2 env"));
assert!(p.is_file());
println!(
"cargo:rustc-link-lib={}",
fname
.file_stem()
.unwrap()
.to_string_lossy()
.strip_prefix("lib")
.unwrap()
);
println!(
"cargo:rustc-link-search={}",
p.parent()
.expect("no library path in LIBXML2 env")
.to_string_lossy()
);
} else {
#[cfg(any(target_family = "unix", target_os = "macos"))]
{
if pkg_config_dep::find() {
return;
}
}
#[cfg(windows)]
{
if vcpkg_dep::find() {
return;
}
}
panic!("Could not find libxml2.")
}
}
#[cfg(any(target_family = "unix", target_os = "macos"))]
mod pkg_config_dep {
pub fn find() -> bool {
if pkg_config::find_library("libxml-2.0").is_ok() {
return true;
}
false
}
}
#[cfg(target_family = "windows")]
mod vcpkg_dep {
pub fn find() -> bool {
if vcpkg::find_package("libxml2").is_ok() {
return true;
}
false
}
}

Hi, libxml itself should be available on iOS and Android via binding for these platforms. I can't help you with the rust crate libxml. We've chosen this dependency for various reason: great XPath support, XML SAX parser and battle proof library. |
|
Hi, |
|
No problem, no offense taken at all! I'm not at expert in iOS/Android but what I would do is to try to build something smaller, maybe just calling libxml though a flutter composant, then trying to build with libxml but with the Rust crate wrapper etc... |

The title but I am getting some issues while building it. If someone know how to solve this cryptic error.
What I am trying to do here:
Creating a library in dart by wrapping the rust hurl library with help of flutter_rust_bridge.
When I try to build this with xcode for macos.
