Build for Android
#595

|
I'm trying to build my project (Godot extension) for Android from Fedora 41. I followed the instructions on gdal.org to build gdal for Android and after some wrangling, I got this to work:
sudo dnf install automake bison flex libtool perl-CPAN
cpan IPC::Cmd
git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh -disableMetrics
./vcpkg integrate install
unset CC CXX
export ANDROID_NDK_HOME=<path/to/android_ndk_home>
./vcpkg install gdal:arm64-androidThen I build my project using: LIBRARY_PATH=<path/to/ndk/libs> GDAL_HOME=<path/to/vcpkg/gdal/stuff> GDAL_VERSION=<x.y.z> GDAL_STATIC=1 cargo build --target=aarch64-linux-android --release
I got past my previous errors but have other link issues. See below. |

I needed to do the following: rustup target add aarch64-linux-android
cargo install cargo-ndk
ANDROID_NDK_HOME=<path/to/android/ndk> GDAL_HOME=<path/to/vcpkg/gdal/stuff> GDAL_VERSION=<x.y.z> GDAL_STATIC=1 cargo ndk -t arm64-v8a build --target=aarch64-linux-android --releaseThis almost works but now I get these link errors: Anyone have an idea of what the problem might be? Cound it be that the linker is just missing openjpeg (which is actually named libopenjp2.a)? |

Thanks for the info. I'll dig deeper into it today. This is the closest I've been to getting something going on Android. |

I don't need JPEG 2000. My app actually only needs a very small set of gdal functionality. I'm looking into vcpkg to see if there's a way to exclude what I don't need (or at least JPEG 2000). |

Glad to hear. The upcoming version has some support for building from source, that might be interesting to test. |

I'm now getting the following error (this just showed up in the last couple weeks): Anyone have an idea? I'm confused about why it's trying to use a system include file instead of just include files from the Android NDK. |
