A simple program to allocate and free heap memory: int main(int argc, char **argv) { char *b1, *b2, *b3, *b4, *b_large; b1 = malloc(8); memset(b1, 0xaa, 8); b2= malloc(16); memset(b2, 0xbb, 16); b3 = malloc(25); memset(b3, 0xcc, 25); b4= malloc(1000);…
As per the man page, I have defined _GNU_SOURCE before the inclusion of <fcntl.h>: #include <stdio.h> #define _GNU_SOURCE /* For Linux's fallocate(). */ #define HAVE_FALLOCATE 1 #include <fcntl.h> int main(void) { printf("%dn", FALLOC_FL_KEEP_SIZE); } which I compiled with: gcc-13 -std=gnu2x…
I'm on an Ubuntu x86_64 system. I know we have the strace command to trace the system calls in our programs. However I'd like to know if there is a way ( other than inspecting the GNU C library source…
In the section "Is musl compatible with glibc?" the musl FAQ states that: Binary compatibility is much more limited, but it will steadily increase with new versions of musl. At present, some glibc-linked shared libraries can be loaded with musl,…

When compiling this code #include <math.h> double *y0; int main() { return 0; } with gcc 13.2.0 from latest debian-sid, I get the following error: gcc -o a.out proof.c -Wall -lm proof.c:3:9: error: 'y0' redeclared as different kind of symbol…
I'm trying to use the Heroku command line on Ubuntu, but coming up with an error, which I don't think is related to Heroku specifically. When I run heroku login I get /snap/heroku/current/bin/node: /snap/core/current/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by…
I have an executable compiled on a latest operating system. The executable is just a few lines of math code. Problem is, it's crashing when it's running on a different system. ImportError: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by /path/to/mylib.cpython-36m-x86_64-linux-gnu.so)…
the steps is: update the make version to 4.8 update the gcc version to 12.2.0 Perform the following steps to compile glibc： tar zxf glibc-2.28.tar.gz && cd glibc-2.28 mkdir build && cd build ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin make…
According to this page https://sourceware.org/glibc/wiki/libmvec, I should be able to manually vectorize a few complicated instructions like cosine by using the libmvec functions. However, I don't know how to get gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 to recognize them. Am I missing…
