Hello,
I've been trying to compile some open source C/C++ code on OpenBSD (that
already builds on Mac, Windows, and linux) and one error I hit on one
project was a link error trying to link to the backtrace() function.
So I went to check the man page. But the man page does not document
what linker flag is needed. Luckily the FreeBSD man page does.
Contrast the first few lines of each:
-----------------------------------------------
FreeBSD:
NAME
backtrace -- fill in the backtrace of the currently executing
thread
LIBRARY
Backtrace Access Library (libexecinfo, -lexecinfo)
SYNOPSIS
#include <execinfo.h>
-----------------------------------------------
-----------------------------------------------
OpenBSD:
NAME
backtrace, backtrace_symbols, backtrace_symbols_fd,
backtrace_symbols_fmt, backtrace_symbols_fd_fmt -- fill in the
back-
trace of the currently executing thread
SYNOPSIS
#include <execinfo.h>
-----------------------------------------------
So tldr: `man backtrace` should name the required linker flag
(-lexecinfo)
Cheers,
Sean
