Distribute a program compiled with MinGW g++

Question

Let\'s say I have created and compiled a simple program using the MinGW 64 (g++ compiler). Running this program on my computer and looking in Process Explorer for what DLL f

Answer 1

For complicated projects where you're not exactly sure which DLL files need to be included to distribute your application, I made a handy dandy Bash script (for MSYS2 shells) that can tell you exactly what DLL files you need to include. It relies on the Dependency Walker binary.

#!/usr/bin/sh

depends_bin="depends.exe"
target="./build/main.exe" # Or wherever your binary is
temp_file=$(mktemp)
output="dll_list.txt"

MSYS2_ARG_CONV_EXCL="*" `cygpath -w $depends_bin` /c /oc:`cygpath -w $temp_file` `cygpath -w $target`
cat $temp_file | cut -d , -f 2 | grep mingw32 > $output

rm $temp_file

Note that this script would need to be modified slightly for use in regular MSYS (the MSYS2_ARG_CONV_EXCL and cygpath directives in particular). This script also assumes your MinGW DLL files are located in a path which contains MinGW.

You could potentially even use this script to automatically copy the DLL files in question into your build directory as part of an automatic deploy system.
