For now I decided to not change that script, but just leave comments. I don't have access to MSVC or clang-cl outside vcpkg CI, so I can't check any logs (or paths with spaces) for these triplets unless CI fails. |

Removing -avoid-version is a key change to make NDK r26 work. Libtool doesn't need it any longer explicitly. And shared libs are already broken for Android. I will add another change which modifies the generated libtool scripts in the build directories, but I will put this behind a condition.

--target belongs into CC/CXX. libtool doesn't invoke the linker it invokes the linker through the compiler.

What is your proposal? Any references?
The compiler which invokes the linker is clang here. --target already is in the LDFLAGS, and it is used this way during configure when libtool is not used. This change makes libtool` pass it through (as passed in). And this is needed to make clang select the right runtime artifacts for Android and the desired API level.

Hmm while searching for the issues i found: wolfSSL/wolfssl#4519
So you should probably use the wrapper script instead of invoking clang directly.
Is there an issue raised with libtool? Seems more like a generic problem with it.

There is also https://debbugs.gnu.org/db/25/25944.html from 2017. So probably just missing somebody who is willing to submit a patch.
I don't think vcpkg should currently correct this.

To put things straight, these are the official NDK instructions for autotools:
https://developer.android.com/ndk/guides/other_build_systems#autoconf
So there are prefixed tools. But they are not the tools used in vcpkg's CMake toolchains and forwarded to autotools as implemented in vcpkg_configure_make.

Then that should be changed

Change vcpkg's cmake toolchain setup?
Or transform Android clang --target=x86_64-linux-android32 into x86_64-linux-android32-clang if it exists?
Or simply write a wrapper of that name ourself?

Change the toolchain to use the wrapper since the wrapper probably needs to be used in more places?
Alternatively, change it to the wrapper in cmake_get_vars?
I don't see a need to generate a wrapper ourself if upstream provides one (but I also already thought about generating wrappers for windows to make sure flags a correctly passed.).

I'm afraid this is not acceptable because it is not the recommended use of the NDK with CMake. And it would need to deal with different versions of the NDK.
Alternatively, change it to the wrapper in cmake_get_vars?
I'm afraid this is not acceptable because this affects more places, including user ports.

Changes numbered
C<n>for further reference. Don't renumber.C1: Includes #30381: Fix processing ofCMAKE_<LANG>_STANDARD_LIBRARIES.-l.C2: Fixes #14389SKIP_CONFIGUREoption.C3: Redirects man and doc dirs for the debug build.- Establishes consistency between release and debug.- Simplifying post-build cleanup for debug.- Behavioral change may affect ports bydebug/sharenow appearing. Fixed forliburing.(Too disruptive, may break user ports.)
C4: Fixes passing of linker options for windows, #31228 (comment).C5: Generally moves "ABI flags" from CFLAGS/CXXFLAGS to CC/CXX.Establishes consistency: This was already done for Apple toolchains.Actually for Apple toolchains, all CFLAGS used to be added to CC. This is now reduced to the set of known ABI flags.Allows to remove the-avoid-versionlibtool flag which breaksconfigure, cf. [vcpkg/scripts/make] avoid versioning for android #17089 (comment).Fixes [libb2] build failure with Android NDK r26 canary #31332: dynamic builds for Android. (Reverts [vcpkg/scripts/make] avoid versioning for android #17089.)C6: Improves warnings about unsupported whitespace. There are three different cases:C7: UpdatesCCASsetup forgmpandnettle.C8: On this occasion, adds aVSCLANGtool tovcpkg_find_acquire_programto improve behaviour when VS's clang isn't found. (No pointless LLVM download, no lengthy extraction, but clear messages. There were some issues were users struggled with that.) This addition is feasible/cheap since #30780.C9: Fixes #32282, use GNU make on FreeBSD (credits: @SchaichAlonso)C10: Fixes #30479, problems with special chars in paths due to use in regex....
