I an using [Coturn Master][1] open source project for P2P communication for one of my application. So I created a client Library from the project using cmake build steps mentioned in the installed file. I used below steps to build a library using Terminal in Mac OS. $ cd coturn $ mkdir build $ cmake ..

I’d like to perform polynomial multiplication of two uint64_t values (where the least significant bit (the one got by w&1) is the least significant coefficient (the a0 in for w(x)=∑iai*xi )) on ARM and get the least significant 64 coefficients (a0…a63) of the result as uint64_t (so result>>i&1 is ai). It’s not clear to me, ..
I have two static third-party libraries which have same exported symbol, and all of symbols I what to use in my shared library. objcopy can redefine symbols from library. After install binutils package from brew, extract all *.o files from static library and and call objcopy for each *.o files objcopy –redefine-sym pack objects with ..
I am using the mmap system call which maps a file into memory. The function load_asm_code first compiles the generated code and then maps it into memory. The variable buf is a pointer to the mapped area. Now the problem is that before I call the test function (that is mapped into memory) I need ..

I have a multi-threaded CPP program(a listener thread, a data processor thread) shifted on the arm64-v8a Android platform. Recently it continues to crash due to the same reason shown below: E CRASH : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr fffffffffffffffc To my best knowledge, since the fault addr remains the same, it cannot ..
I am trying to run the ArmIE emulator. I compiled source file with GCC 10.3.0 for SVE by using: gcc -O3 -march=armv8-a+sve -o hello hello.c armie -msve-vector-bits=512 ./hello But get an error message: armie’s SVESigHandler caught signal SIGSEGV from the process being emulated, passing it to the default signal handler. Guest process terminated by signal: ..
I have a c++ library xyz.so which has been created using a x86-64 machine. The output of file -L xyz.so is ELF 64-bit LSB shared object, x86-64, verison 1 (GNU/Linux), dynamically linked And the architecture of my machine uname -a is aarch64 GNU/Linux **Question:** I want to use the xyz.so library with my c++ code ..
im no encryption expert. but i remember in 2018, i literally copied and pasted some encryption code and was able to just edit a few variables and put it into the functions i wanted. it worked great. i was encrypting strings with just a function call and a key and a vector. this was on ..
I’m trying to match the behavior exactly between an application running on both x86_64 and aarch64/arm64. However, they differ in how they cast a floating point number to an integer when it’s outside of the possible range of integers. Consider the following example: #include <stdio.h> #include <cstdint> void cast(float value) { printf("uint32_t(%.2f) = %un", value, ..
