Hi

Personally I only go with shared libraries, and the one time I had to use static libraries I ended up hitting quite a number of broken ones.

Attached below is the script I use to automatically collect dependencies. Only ones you'll still have to collect manually are the runtime loaded ones.

Hope this helps Sandro

#!/bin/bash

# Halt on errors set -e

installroot=$PWD/dist;

if [ $# -lt 1 ]; then echo "Usage: $0 win32_binary [--debug]" exit 1; fi

if [ ! -f "$1" ]; then echo "Cannot find file $1" echo "" echo "Usage: $0 win32_binary [--debug]" exit 1; fi

# Note: This script is written to be used with the Fedora mingw environment if [ "$(file $1 | grep -o x86-64)" == "x86-64" ]; then echo "Scanning dependencies for $1 (64bit binary)" MINGWROOT=/usr/x86_64-w64-mingw32/sys-root/mingw else echo "Scanning dependencies for $1 (32bit binary)" MINGWROOT=/usr/i686-w64-mingw32/sys-root/mingw fi

if [ "$2" == "--debug" ]; then withdebug=1 fi

isqt5=false

# Collect dependencies function isnativedll { # If the import library exists but not the dynamic library, the dll ist most likely a native one local lower=${1,,} [ ! -e $MINGWROOT/bin/$1 ] && [ -f $MINGWROOT/lib/lib${lower/%.*/.a} ] && return 0; return 1; }

function cpDep { # Copy the specified binary dependency destdir="$installroot/${2:-$(dirname $1)}" name="$(basename $1)" test -e "$destdir/$name" && return 0 if [ ! -e "$MINGWROOT/$1" ]; then echo "Error: missing $MINGWROOT/$1" return 0 fi mkdir -p "$destdir" || return 1 echo "Copying $1" cp -a "$MINGWROOT/$1" "$destdir/$name" || return 1 if [ $withdebug ]; then test -e "$MINGWROOT/$1.debug" && cp "$MINGWROOT/$1.debug" "$destdir/$name.debug" && echo "Copying $1.debug" || echo "Warning: missing $name.debug"; fi autoCpDeps $destdir/$name || return 1 return 0 }

function autoCpDeps { # Collects and links the dependencies of the specified binary for dep in $(mingw-objdump -p "$1" | grep "DLL Name" | awk '{print $3}'); do # Hacks / Workarounds if [ "$dep" == "LIBPQ.dll" ]; then dep="libpq.dll" elif [ "$dep" == "QtUiToolsd4.dll" ]; then continue; elif [ "$dep" == "Qt5Core.dll" ]; then isqt5=true fi

    if [ ! -f "$dep" ] && ! isnativedll "$dep"; then
        cpDep bin/$dep || return 1
    fi
done
return 0

}

mkdir -p dist/bin cp -a $1 dist/bin autoCpDeps $1 if [ $withdebug ]; then cpDep bin/gdb.exe fi if [[ $isqt5 == true ]]; then mkdir -p dist/bin/platforms cp -a $MINGWROOT/lib/qt5/plugins/platforms/qwindows.dll dist/bin/platforms/ autoCpDeps $MINGWROOT/lib/qt5/plugins/platforms/qwindows.dll fi

Wow, this is FANTASTICALLY helpful. I keep finding myself manually curating the list of DLL files to include in packages and that's a royal PITA. I will definitely switch to using this. But, I agree with Richard - maybe this could be included into a package? Just make us up a source-only package that drops this script into /usr/bin/ somewhere and it will make me grateful!

Is it documented anywhere that static or shared libraries are preferred?

I've got several mingw packages in my COPR[1] that can and probably should be added to Fedora, but I'm also a developer on a project and I produce windows installers from my Fedora machine. Some of the dependencies I built with shared (dll) libraries and probably spent 10's of hours figuring out how to see which ones needed to be bunded in the installer

https://github.com/drowe67/freedv-gui/blob/master/cmake/GetDependencies.cmak...

So that makes me thing that static libraries would be better or should be enforced. If not, how do you package programs with shared libraries?

Thanks, Richard
