OpenSSL: drop `libunwind` linking for Clang-based Android NDK by olliwang · Pull Request #815 · cpp-pm/hunter

olliwang · 2025-09-16T09:40:23Z

Since Android NDK r23+, unwind support is bundled in the Clang toolchain and explicit linking to libunwind is no longer required. Linking this library causes build errors on modern NDKs.

This change removes libunwind from the configure options to ensure successful builds for NDK r23+.

I've followed this guide step by step carefully. Yes

Clang-based Android NDKs bundle unwind support and do not require explicit linking. Passing malformed flags like "-l-l:libunwind.a" caused build failures with ld.lld on NDK r23+. This change removes those flags from configure options to ensure successful builds.

sounds reasonable. I have no experience in Android toolchains thoug.

Android build seems to still fail (probably a different error)

Please ping me when you are happy with the state of this PR

@NeroBurner Yes, I've tested on NDK 23+ and it works perfectly. Thanks :)

Could you explain to me why the CI / OpenSSL android-ndk-api-35-arm64-v8a-libcxx14 ubuntu-24.04 toolchain fails? Is the NDK 23+ thing different to the API? Just so I have a ROUGH understanding what is happening here and having a slight chance that the toolchain may be fixed

I cannot find the source code of android-ndk-api-35-arm64-v8a-libcxx14.cmake but I am guessing the toolchain is very old. I remembered the original Android toolchain only support NDK 16 or 17. I modified mine long time ago to support NDK 22. Now I have to update to NDK 28 because Google Play requires support for 16 KB page sizes now and NDK 28 will build C++ libraries for 16 KB page size out-of-box.

On current master (roughly Hunter v0.26.3) the mentioned error with libunwind is present (which this PR fixes 🎉 ):

ld.lld: error: unable to find library -l-l:libunwind.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I see that the Toolchain runs on the provided ndk 27.3

The build matrix of master shows that the android build, the windows store build and the ios-nocodesign builds were already failing

In this PR essentially the same 3 toolchains are failing:

The error for the android toolchain is different:

I cannot find the source code of android-ndk-api-35-arm64-v8a-libcxx14.cmake but I am guessing the toolchain is very old

Or I created it wrong 😅 I changed their creation in #780

The toolchains are generated now by the .github/workflows/set_matrix.py script. If you want to create the toolchains for the OpenSSL project run the following:

python3 .github/workflows/set_matrix.py OpenSSL

Then you'll get the toolchain files in .github/toolchains/android-ndk-api-35-arm64-v8a-libcxx14.cmake

The toolchain file looks as follows:

# toolchain file generated by set_matrix.py, do not modify!
set(CMAKE_SYSTEM_NAME "Android")
set(CMAKE_SYSTEM_VERSION "35") # API level
set(CMAKE_ANDROID_ARCH_ABI "arm64-v8a")
set(CMAKE_ANDROID_NDK "$ENV{ANDROID_NDK}") # provided by GitHub

string(COMPARE EQUAL "${CMAKE_ANDROID_NDK}" "" _is_empty)
if(_is_empty)
  message(FATAL_ERROR
      "Environment variable 'ANDROID_NDK' not set"
  )
endif()

# ANDROID macro is not defined by CMake 3.7+, however it is used by
# some packages like OpenCV

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

Is it grossly wrong? 😅

Sure. This toolchain was modified based on the original Android toolchain. Be aware that I’m targeting C++20 for my purposes. It works well with all the Hunter packages I’m using, though I definitely haven’t tested every package.

With filled out I was referring to have the template variables like "@ANDROID_ABI@" filled out with the actual values. Sorry for being unclear

It's arm64-v8a in my environment.

NeroBurner · 2025-09-16T14:16:32Z

And all the other values? Can you copy the final version after all the @@ template variables got filled out with your environment variables? 🙏

olliwang · 2025-09-16T15:42:33Z

No problem. They look like this:

olliwang · 2025-09-16T15:49:58Z

BTW, I also have some fixes for other packages built with the latest iOS 26 / macOS 26 SDK. Could you take a look at them as well?

libpng: hunter-packages/libpng#9
zlib: cpp-pm/zlib#2

I submitted these pull requests because the current versions cause build errors with the newer SDK, which was officially released this month.

NeroBurner · 2025-09-16T19:11:59Z

Thank you very much. I'll try to take a look as soon as possible. Thanks again for your contributions!

Fixes: cpp-pm#807 * docs: port foo.rst to foo.md (cpp-pm#808) I like to write documentation in MarkDown better than in `*.rst`. First step is to have new package documentation in MarkDown. So port the reference `foo.rst` to `foo.md`. * docs: fix deprecation warning replacing spelling with spelling:word-list (cpp-pm#811) When building the docs on Ubuntu 24.04 many deprecation warnings are shown ``` direct use of the spelling directive is deprecated, replace ".. spelling::" with ".. spelling:word-list::" ``` Fixes: cpp-pm#806 * docs: foo.md: remove double space from enumeration * libdeflate: add new package with v1.24-p0 (cpp-pm#812) Need to use a patched version of `libdeflate` as the created CMake config contains absolute paths breaking the caching. Once ebiggers/libdeflate#434 is merged and released we can use pure upstream. Fixes: cpp-pm#804 * libdeflate: update copyright * TIFF: update to v4.7.0-p0 (cpp-pm#813) Unpinn OpenCV 4.10 because TIFF 4.7.0 fixes build issues on Linux. Fixes: cpp-pm#765 Remove old `FindTIFF.cmake` module. Not needed anymore (and probably wasn't needed for a long time). Update to use https://github.com/cpp-pm/libtiff/releases/tag/v4.7.0-p0 hunterized dependencies: - `zlib`: default ON, only dependency available in previous 4.0.2 hunterized version) - `libdeflate`: default: ON, available in Hunter starting with `v0.26.3` cpp-pm#804 - `jpeg`: default OFF, newly hunterized - `lzma`: default OFF, newly hunterized - `zstd`: default OFF, newly hunterized Not hunterized dependencies: - `jbig=OFF` - `lerc=OFF` - `webp=OFF` Update the TIFF example to use use `stdio.h` `remove()` instead of `unlink()`. Fixes: cpp-pm#789 * TIFF: fix mention about zstd being supported * Add new package OpenJPH 0.23.0 (cpp-pm#814) Add upstream version of package `OpenJPH`. The `TIFF` dependency is optional and I had some issues when adding `hunter_add_package(TIFF)` with missing includes. So adding with `TIFF` disabled. Fixes: cpp-pm#805 * Imath: update to 3.2.1 (cpp-pm#817) Update `Imath` package for OpenEXR 3.4.0 compatibility as described in the `OpenEXR` install documentation (3.4.0+ should use Imath 3.2). Fixes: cpp-pm#816 * OpenSSL: strip libunwind flags for Clang-based Android NDK (cpp-pm#815) Clang-based Android NDKs bundle unwind support and do not require explicit linking. Passing malformed flags like `-l-l:libunwind.a` caused build failures with `ld.lld` on NDK r23+. This change removes those flags from configure options to ensure successful builds. * OpenEXR: add version 3.4.0-p0 (cpp-pm#818) Update `OpenEXR` with Hunterized `v3.4.0-p0` version: https://github.com/cpp-pm/openexr/releases/tag/v3.4.0-p0 Dependencies: - add `Imath` as dependency (unchanged) - add `libdeflate` as depencency, introduced in `v3.2.0` - removed `zlib` dependency since `v3.2.0`, replaced by `libdeflate` - add `OpenJPH` as dependency, since `v3.4.0` Fixes: cpp-pm#788 * CI: install python requests module to fix upload cache script (cpp-pm#820) On the `master` branch the pipelines fail at the `upload-cache-to-github.py` script as it is missing the `requests` python module. Install it before the build to have a working cache upload again. Fixes: cpp-pm#819 * PNG: update to v1.6.36-p4 with CMake 3.11 requirement (cpp-pm#823) Update to release https://github.com/cpp-pm/libpng/releases/tag/v1.6.36-p4 * Jpeg: update to v9f-p1 with CMake 3.10 (cpp-pm#822) Integrate cmakeified version: https://github.com/cpp-pm/jpeg/releases/tag/v9f-p1 Fixes: cpp-pm#821 * CI: install gitpython python module for cache upload script (cpp-pm#829) Fixes: cpp-pm#827 * giflib: update to v5.2.2-p0 (cpp-pm#828) use https://github.com/cpp-pm/giflib/releases/tag/v5.2.2-p0 with updated minimum CMake 3.10 version. Fixes: cpp-pm#824 * minizip: update to 1.0.1-p4. (cpp-pm#833) Update to release https://github.com/cpp-pm/minizip/releases/tag/v1.0.1-p4 Fixes: cpp-pm/minizip#1 * ZLIB: update to v1.3.1-p0. (cpp-pm#831) Update to release https://github.com/cpp-pm/zlib/releases/tag/v1.3.1-p0 Fixes: cpp-pm#735 * OpenCV+Extra+ippicv: add version v4.12.0-p0 (cpp-pm#832) Update OpenCV, OpenCV-Extra and ippicv to `v4.12.0-p0`. Those packages belong together and should be updated at once. - OpenCV: update to 4.12.0-p0 - OpenCV-Extra: update to 4.12.0 release - ippicv: update to 20250130 for OpenCV 4.12.0 - keep APPLE version to ippicv 20240201 from OpenCV 4.10.0 - add `WITH_VTK=OFF` - Unpin OpenCV for all as Linux build is now fixed with fixed TIFF/OpenEXR Fixes: cpp-pm#801 * opencv: update to v4.12.0-p1 with CUDA 12.9 fix (cpp-pm#835) Update to `4.12.0-p1` with CUDA 12.9 fix cherry-picked: opencv/opencv@e2d87de Link to Release: https://github.com/cpp-pm/opencv/releases/tag/v4.12.0-p1 Fixes: cpp-pm#834 * Add Boost version 1.84.0, 1.85.0, and 1.86.0 * Support for Boost 1.86 with added component configuration * Update download url for Boost Update download url from jfrog to boost-archive. --------- Co-authored-by: Aliaksandr Anishchuk <oav.other@gmail.com> Co-authored-by: Harry Mallon <hjmallon@gmail.com> Co-authored-by: Dominik Nussbaumer <4436784+tnixeu@users.noreply.github.com> Co-authored-by: André Falk <andre.falk@tutanota.com> Co-authored-by: simbahebinbo <lansheng228@163.com> Co-authored-by: NeroBurner <pyro4hell@gmail.com> Co-authored-by: Ronny Nowak <dargun@gmx.net> Co-authored-by: craffael <raffael@casagrande.ch> Co-authored-by: Graham Reeds <graham.reeds@gmail.com> Co-authored-by: Rahul Sheth <rahul@snap.com> Co-authored-by: Joerg-Christian Boehme <joerg@chaosdorf.de> Co-authored-by: Timothy Pak <httpak@connect.ust.hk> Co-authored-by: Andrei Svatko <andrei.svatko@regula.by> Co-authored-by: Olli Wang <olliwang@ollix.com> Co-authored-by: Ola Engwall <ola.engwall@hypergene.se>
