I tried googling it but all results were about C++'s throw std::exception(). I was reading through libraries (was curious how stuff like printf, malloc and FILE were implemented) and came across the definition for the malloc function: extern void *malloc…
I've been playing around my code editor and accidentally made this. This compiles fine, and works as intended. For additional context, I'm using GCC on Debian 11. As for how I knew the prototypes, VS Code's IntelliSense told me. Why…
On my host system (Ubuntu, 64Bit) I use gcc/g++ compilers to crosscompile my library for my Android app (arm64-v8a). On calling functions from my App I receive messages that libraries like libc.so.6 or libstdc++.so.6 cannot be found. Within my /usr…
I have a docker container that has been successfully installing GDAL 3.5.0 up until Nov 8th, 2022. The last passing build with the exact same code was on Nov 7th. The failures occur in a remote environment on the default…
I'm currently trying to build code using gcc / g++ like this: g++-10 -std=c++2a -Wall -Wextra -c -o hw01.o hw01.cpp (Also the same outcome with gcc-10, gcc, g++) And I have a static check in my Code: static_assert(__cplusplus >= 202002L);…
While learning C++, I tried to compile a HelloWorld program using the 'gcc' command' and found that I needed to add the '-lstdc++' option for it to compile successfully: gcc HelloWorld.cpp -lstdc++ However, I idly tried to use 'c++' as…
From the manual page I know that: exit() flushes output buffers while _exit,_Exit,exit_group don't. In the code below, the content of test.log will be hellonhellon only if exit() was called in child process, which is the same as I tested.…
My Mac updated Xcode to version 14.0. After installing the new command line tools I started running into issues with the version of ld that it ships with. More specifically I have a project I compile with the g++-12 compiler…
I am trying to understand why the behaviour of segfault messages can differ depending on execution environment. I have the following C code that I am using to deliberately trigger a segfault: #include <stdio.h> int main() { int* p =…
I have a program compiled with gcc 11.2, which allocates some RAM memory first (8 GB) on heap (using new), and later fills it with data read out in real-time from an oscilloscope. uint32_t* buffer = new uint32_t[0x80000000]; for(uint64_t i…
