I tried to compile opencv for x86_64 and arm64-v8a, but it threw error below:

How to solve it?
It seems to be a problem with the stl library. You could try changing the stl in CMAKE to c++ static:
Flag: ANDROID_STL Value: c++_static

I am new to LLVM and clang. I am working on a tool that uses LLVM/clang in the backend as a compiler. With the recent changes in LLVM tool, I have started getting following error:
<inline asm>:1:13: error: unexpected token in argument list
lock addb 2$2, 1048576
^
LLVM ERROR: Error parsing inline asm
I do not have any idea how to resolve this. Any input is appreciated.
Hello I' ve got issue on caffe installation. I did everything in accordance to the instruction https://github.com/BVLC/caffe/wiki/Ubuntu-16.04-Installation-Guide (for CPU version)
On command make all I've got the following output:

Here is also a lot of text in output but I cannot upload it because of limit on number of characters
Makefile:591: recipe for target '.build_release/src/caffe/util/io.o' failed

Can somebody help me with this problem?
OS: Ubuntu 16.04
cmake version 3.5.1
Cuda version: 10.0.130
The problem was in 4th version of OpenCV. Caffe dosen't work with it. When I installed 3rd version everything was ok.
I need to build OpenCV from source, because I want to make modifications to it. So using pre-built binaries is not an option for me. I'm doing this on Windows 8. I do not have MS Visual Studio, and I don't want to use it.
Here is how I reproduce the build error:
I git clone https://github.com/opencv/opencv
I use CMake 3.7.1, press Configure, then press Generate. It seems to work (no errors). I named the output folder opencv/release.
I go to the opencv/release folder, and type mingw32-make.
Eventually, after compiling for a while, it displays the following error message:
Building CXX object modules/core/CMakeFiles/opencv_core.dir/src/parallel.cpp.obj
modules\core\src\parallel.cpp:135:43: error: operator '&&' has no right operand

Note: I tried to compile both with and without TPP (in the CMake config), and I get the same error message.
Also, I read the other similar questions on StackOverflow and the answers do not help.
Have to compile security library (create static library) for IOS.
Below is the makefile snippet:
SDK_ROOT=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk
#CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc
CC=llvm-gcc
TARGET=security
ARCH=arm64
Now on changing the ARCH=armv7, compilation is successful but for ARCH=arm64
Compiling the same code gives error as below:
crypto.c:580:18: error: implicit declaration of function 'aes_hardware_cbc' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
The above error can be resolved on adding declaration of the function in header file
But I wanted to know how architecture changes brings on Implicit Function Declaration errors or , change warning to errors.

MAC OS: 10.11 EL Captain
Iphone SDK: iPhoneOS9.0.sdk
Compiler: llvm-gcc (/usr/bin)
I'm having trouble installing the rinku gem version '1.7.3' on Mavericks. I followed the advice of another post that suggested to install apple-gcc42 but that didn't help. I've also tried searching google and stack overflow but couldn't find this exact issue. Here is the error:
