turbojpeg-sys fails to build with cc 1.0.84 with Android NDK 21

[tyilo]

I have a project depending on turbojpeg-sys which I need to compile for the armv7-linux-androideabi target for Android API level 17, meaning that I need to use Android NDK v21.

Compiling a project with the latest version of turbojpeg-sys with version 1.0.83 of cc works:

# Setup project
cd /tmp
cargo new cc-repro
cd cc-repro
rustup override set 1.67.1
cargo add turbojpeg-sys@=0.2.3 -F cmake --no-default-features
cargo add cc@=1.0.83

# Setup variables
export NDK_VERSION=21
ANDROID_API_LEVEL=17
export ANDROID_ABI=armeabi-v7a
export CARGO_BUILD_TARGET=armv7-linux-androideabi
export NDK_TARGET=armv7a-linux-androideabi
export ANDROID_NDK=$HOME/Android/Sdk/ndk/21.4.7075529

NDK_BIN_PATH=$ANDROID_NDK/toolchains/llvm/prebuilt/linux-x86_64/bin

export AR="$NDK_BIN_PATH/llvm-ar"
export CC="$NDK_BIN_PATH/$NDK_TARGET$ANDROID_API_LEVEL-clang"
export AS="$CC"
export CXX="$NDK_BIN_PATH/$NDK_TARGET$ANDROID_API_LEVEL-clang++"
export LD="$NDK_BIN_PATH/ld"
export RANLIB="$NDK_BIN_PATH/llvm-ranlib"
export STRIP="$NDK_BIN_PATH/llvm-strip"
export CMAKE_TOOLCHAIN_FILE="$ANDROID_NDK/build/cmake/android.toolchain.cmake"

export CARGO_TARGET_ARMV7_LINUX_ANDROIDEABI_LINKER="$CC"

export ANDROID_PLATFORM=android-$ANDROID_API_LEVEL
export ANDROID_TOOLCHAIN=clang

# Build (succeeds)
cargo build

However, if I upgrade cc to version 1.0.84 the build fails:

cargo add cc@=1.0.84
export RUST_BACKTRACE=1
cargo build

Error:

cmake uses cc to obtain the compiler, I think this might be related to #709 .

@tyilo Can you try compiling with cc@=1.0.83 and get cmake to print the compiler it is used?

I suspect it might be using gcc with cc@=1.0.83 and clang with cc@1.0.84

[tyilo]

@NobodyXu There is no gcc compiler included in the Android NDK, only clang, so that would be impossible I think (especially when the build completes successfully).

Anyway here is the values of c_compiler, cxx_compiler and asm_compiler in cmake when running with cc@=1.0.83:

c_compiler: Tool { path: "/home/tyilo/Android/Sdk/ndk/21.4.7075529/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi17-clang", cc_wrapper_path: None, cc_wrapper_args: [], args: ["-O0", "-DANDROID", "-ffunction-sections", "-fdata-sections", "-fPIC"], env: [], family: Clang, cuda: false, removed_args: [] }
cxx_compiler: Tool { path: "/home/tyilo/Android/Sdk/ndk/21.4.7075529/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi17-clang++", cc_wrapper_path: None, cc_wrapper_args: [], args: ["-O0", "-DANDROID", "-ffunction-sections", "-fdata-sections", "-fPIC"], env: [], family: Clang, cuda: false, removed_args: [] }
asm_compiler: Tool { path: "/home/tyilo/Android/Sdk/ndk/21.4.7075529/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi17-clang", cc_wrapper_path: None, cc_wrapper_args: [], args: ["-O0", "-DANDROID", "-ffunction-sections", "-fdata-sections", "-fPIC"], env: [], family: Clang, cuda: false, removed_args: [] }

Here is the same when using cc@=1.0.84 (yanked):

c_compiler: Tool { path: "/home/tyilo/Android/Sdk/ndk/21.4.7075529/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi17-clang", cc_wrapper_path: None, cc_wrapper_args: [], args: ["-O0", "-DANDROID", "-ffunction-sections", "-fdata-sections", "-fPIC", "--target=armv7-linux-androideabi"], env: [], family: Clang, cuda: false, removed_args: [], has_internal_target_arg: false }
cxx_compiler: Tool { path: "/home/tyilo/Android/Sdk/ndk/21.4.7075529/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi17-clang++", cc_wrapper_path: None, cc_wrapper_args: [], args: ["-O0", "-DANDROID", "-ffunction-sections", "-fdata-sections", "-fPIC", "--target=armv7-linux-androideabi"], env: [], family: Clang, cuda: false, removed_args: [], has_internal_target_arg: false }
asm_compiler: Tool { path: "/home/tyilo/Android/Sdk/ndk/21.4.7075529/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi17-clang", cc_wrapper_path: None, cc_wrapper_args: [], args: ["-O0", "-DANDROID", "-ffunction-sections", "-fdata-sections", "-fPIC", "--target=armv7-linux-androideabi"], env: [], family: Clang, cuda: false, removed_args: [], has_internal_target_arg: false }

Seems like the difference is that --target=armv7-linux-androideabi is getting passed to clang in 1.0.84, but not in 1.0.83.

[NobodyXu]

hmmm @tyilo Can you do a bisect on v1.0.83..v1.0.84 to find out which commits caused this error?

[tyilo]

@NobodyXu Done:

Thanks!

I will investigate this, would be great if you can also get the build commands run by cmake.

[tyilo]

Seems to be the following with at commit 53564e0:

cd "/home/tyilo/tmp/cc-repro/target/armv7-linux-androideabi/debug/build/turbojpeg-sys-6d3bd97a5c68f099/out/build" && CMAKE_PREFIX_PATH="" "cmake" "/home/tyilo/.cargo/registry/src/index.crates.io-6f17d22bba15001f/turbojpeg-sys-0.2.3/libjpeg-turbo" "-DCMAKE_INSTALL_DEFAULT_LIBDIR=lib" "-DCMAKE_TOOLCHAIN_FILE=/home/tyilo/Android/Sdk/ndk/21.4.7075529/build/cmake/android.toolchain.cmake" "-DCMAKE_INSTALL_PREFIX=/home/tyilo/tmp/cc-repro/target/armv7-linux-androideabi/debug/build/turbojpeg-sys-6d3bd97a5c68f099/out" "-DCMAKE_C_FLAGS= -DANDROID -ffunction-sections -fdata-sections -fPIC --target=armv7-linux-androideabi" "-DCMAKE_CXX_FLAGS= -DANDROID -ffunction-sections -fdata-sections -fPIC --target=armv7-linux-androideabi" "-DCMAKE_ASM_FLAGS= -DANDROID -ffunction-sections -fdata-sections -fPIC --target=armv7-linux-androideabi" "-DCMAKE_BUILD_TYPE=Debug" "-DENABLE_SHARED=0" "-DENABLE_STATIC=1" "-DANDROID_ABI=armeabi-v7a"

and using the previous commit 755e4fe:

cd "/home/tyilo/tmp/cc-repro/target/armv7-linux-androideabi/debug/build/turbojpeg-sys-6d3bd97a5c68f099/out/build" && CMAKE_PREFIX_PATH="" "cmake" "/home/tyilo/.cargo/registry/src/index.crates.io-6f17d22bba15001f/turbojpeg-sys-0.2.3/libjpeg-turbo" "-DCMAKE_INSTALL_DEFAULT_LIBDIR=lib" "-DCMAKE_TOOLCHAIN_FILE=/home/tyilo/Android/Sdk/ndk/21.4.7075529/build/cmake/android.toolchain.cmake" "-DCMAKE_INSTALL_PREFIX=/home/tyilo/tmp/cc-repro/target/armv7-linux-androideabi/debug/build/turbojpeg-sys-6d3bd97a5c68f099/out" "-DCMAKE_C_FLAGS= -DANDROID -ffunction-sections -fdata-sections -fPIC" "-DCMAKE_CXX_FLAGS= -DANDROID -ffunction-sections -fdata-sections -fPIC" "-DCMAKE_ASM_FLAGS= -DANDROID -ffunction-sections -fdata-sections -fPIC" "-DCMAKE_BUILD_TYPE=Debug" "-DENABLE_SHARED=0" "-DENABLE_STATIC=1" "-DANDROID_ABI=armeabi-v7a"

Again, the only difference seems to be the --target=armv7-linux-androideabi flag.

[NobodyXu]

Seems that 53564e0 actually adds --target=armv7-linux-androideabi to the args for compilers.

[glandium]

IIRC, recent clang wants an API version in the target, as in --target=armv7-linux-androideabi16, rather than --target=armv7-linux-androideabi

[thomcc]

That's unfortunate. Is there an environment variable or something we can use to get that value (similar to MACOSX_DEPLOYMENT_TARGET)

[NobodyXu]

@tyilo Can you try cc 1.0.87 to see if it fixes your issue?
Thanks!
