Example/How to Reproduce

repoUrl="https://github.com/libcpr/cpr.git"
gitTag="1.10.5"

git clone --depth 1 --branch $gitTag $repoUrl

cd cpr
mkdir -p build_android
cd build_android

cmake -S .. -DCMAKE_SYSTEM_NAME=Android -DCMAKE_ANDROID_NDK="$ndkPath" -DCMAKE_INSTALL_PREFIX="$ndkPath/sources/third_party/cpr" -DCMAKE_ANDROID_ARCH_ABI=arm64-v8a -DCMAKE_BUILD_TYPE=Release -DCPR_USE_SYSTEM_CURL=OFF -DCPR_ENABLE_SSL=OFF
cmake --build .
cmake --install .

I would like to add that if I remove -DCPR_ENABLE_SSL=OFF, I have the same error as #333 and I couldn't find a fix

Possible Fix

No response

Where did you get it from?

GitHub (1.10.5)

Additional Context/Your Environment

• OS: Ubuntu
• Version: Mantic 23
• Ndk version: r26b

[COM8]

Could you please try disabling zlib for curl via -DCURL_ZLIB=OFF?

Could you provide a bit if information on how to install NDK on Linux? Then I can have a look at it.
But be aware, I do not have any android dev experience.

[Nathan-M-code]

With -DCURL_ZLIB=OFF it builded.
I have to say that I had to manually do that : eb2d418
Or I got this error:

[100%] Linking CXX shared library ../lib/libcpr.so
ld.lld: error: unable to find library -lstdc++fs
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
gmake[2]: *** [cpr/CMakeFiles/cpr.dir/build.make:530: lib/libcpr.so] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:229: cpr/CMakeFiles/cpr.dir/all] Error 2
gmake: *** [Makefile:136: all] Error 2

To use ndk, it is quite easy, manually download it at : https://developer.android.com/ndk/downloads
And add -DCMAKE_SYSTEM_NAME=Android -DCMAKE_ANDROID_NDK="$ndkPath" -DCMAKE_ANDROID_ARCH_ABI=arm64-v8a as parametre for your cmake cmd.
It will compile for android with the specified ndk

I didn't test the compiled libcpr yet, I'll let you know if everything is ok

[COM8]

Ah, linking to stdc++fs was broken and is already fixed with the latest version on master. Could you please try master instead of the 1.10.5 release?

Ref: #987

It worked without any error with ndk r25c (didn't try with r26b) ! Also I needed to set OFF SSL or I got

-- Detecting SSL backend...
-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR) 
-- Could NOT find MbedTLS (missing: MBEDTLS_INCLUDE_DIRS MBEDTLS_LIBRARY MBEDX509_LIBRARY MBEDCRYPTO_LIBRARY) 
CMake Error at CMakeLists.txt:139 (message):
  No valid SSL backend found! Please install OpenSSL, Mbed TLS or disable SSL
  by setting CPR_ENABLE_SSL to OFF.

Same as #333
Why OpenSSL is not found the same way as if we build cpr without ndk ?

TLDR: OpenSSL Detection is not working correctly. You have to set it manually like we are doing it for macOS inside the CI:

cpr/.github/workflows/ci.yml

Lines 256 to 257 in 1ad1cd2

	OPENSSL_ROOT_DIR: "/usr/local/opt/openssl@3"
	OPENSSL_LIBRARIES: "/usr/local/opt/openssl@3/lib"

FYI, if you use vckpkg it has an older version (1.10.5#2), I've created an issue to update cpr to 1.11.0 which seems like fixing NDK linking issue. microsoft/vcpkg#41876
