[liblzma] Build error on arm64-android when trying to build GDAL for arm64-android

[JoshMorganAtAuterion]

Hi, when attempting to install GDAL (and exactly liblzma), I received the following error. I installed this using the NDK 21.3.6528147 toolchain, but also faced difficulty installing GDAL with another NDK's toolchain (25.1.8937393 in that case).

The command(s) I used to try and install gdal for arm64-android. Please let me know if there is a workaround.

git pull
./vcpkg update
./vcpkg upgrade
export ANDROID_NDK_HOME=~/Android/Sdk/ndk/25.1.8937393/
./vcpkg install gdal:arm64-android

vcpkg CI uses NDK r26.

[JoshMorganAtAuterion]

Thanks for the quick response. I will pull down r26 and give that a shot!

So, I was indeed able to build using the default static entry for the VCPKG_LIBRARY_LINKAGE, but my project needs to compile GDAL to be dynamically-linked, so I tried updating the triplets/arm64-android.cmake to reflect this and unfortunately that lead to more compilation error.

So, to summarize:

1. I am now using NDK r26
2. I must generate dynamically-linked libraries
3. I switched to using Windows

Here is the general output:

There is no error logged. The -lc looks unusual, but IDK.

vcpkg CI build Android on Linux. This is targeting POSIX on POSIX.

Windows hosts might work to some extent, but with GDAL at the end of a long pipeline, you are very likely to run into problems. This is targeting POSIX on WINDOWS partially using a POSIX runtime (MSYS2). Many ways to fail. For example host tools built by icu are known to get path separators wrong.
