README of copydlldeps.sh

This document was created 2016-02-05. It belongs to copydlldeps.sh and is part of the MXE project.

I call it on the command line like:

/share/mxe/tools/copydlldeps.sh --infile /home/mxeuser/test/i686-w64-mingw32.shared/Application.exe \
				--destdir /home/mxeuser/testdlls/   \
				--recursivesrcdir /home/mxeuser/mxe/usr/i686-w64-mingw32.shared/ \
				--srcdir /home/mxeuser/test/ \
				--copy \
				--enforce /home/mxeuser/mxe/usr/i686-w64-mingw32.shared/qt5/plugins/platforms/ \
				--objdump /home/mxeuser/mxe/usr/bin/i686-w64-mingw32.shared-objdump

It got embedded in a build script like:

MXEPATH=/path/to/mxe
compiler=i686-w64-mingw32.shared
orgDir=/path/to/my/nsis/dll #nsis is then copying all dlls in there to the place where the exe is located

if [ ! $( echo $compiler | grep -q "shared" ) ]; then
	echo "\$compiler=$compiler and contains the word 'shared'" | tee -a $CURLOG

	echo "+-----------------------------------------------+ " | tee -a $CURLOG
	echo "| Starting new MXE copydlldeps.sh by LHE DL5RCW | " | tee -a $CURLOG
	echo "+-----------------------------------------------+ " | tee -a $CURLOG
	echo "currently working in $( pwd ) " | tee -a $CURLOG
	executable=$(  find . -name "*.exe" | tail -n 1 )
if [ -e $MXEPATH/usr/bin/$compiler-objdump ]; then
	echo "now populating dir=${orgDir}/nsis/sharedLibs with dll dependencies of executable=$executable" | tee -a $CURLOG
	$MXEPATH/tools/copydlldeps.sh 	--infile $executable \
					--destdir ${orgDir}/nsis/sharedLibs \
					--recursivesrcdir $MXEPATH/usr/$compiler/ \
					--enforce $MXEPATH/usr/$compiler/qt5/plugins/platforms/ \
					--copy \
					--objdump $MXEPATH/usr/bin/$compiler-objdump | tee -a $CURLOG
else
	echo "now populating dir=${orgDir}/nsis/sharedLibs with dll dependencies of executable=$executable" | tee -a $CURLOG
	$MXEPATH/tools/copydlldeps.sh 	--infile $executable \
					--destdir ${orgDir}/nsis/sharedLibs \
					--recursivesrcdir $MXEPATH/usr/$compiler/ \
					--enforce $MXEPATH/usr/$compiler/qt5/plugins/platforms/ \
					--copy | tee -a $CURLOG
fi

Additional hints

objdump

I checked if there is a mxe objdump. If not, I took the native one on my server. I actually do not know the difference but decided to include it in the script in case it is important to someone enforce

My application is using Qt5 and objdump did not return the needed qwindows.dll - so I enforce the platform folder. You may add multiple --enforce directories using --enforce /path/folder1 --enforce /path/folder2 --enforce /path/folder3 They are NOT recursively copied, only flat. See: string=$( find $enforcedDirectory -maxdepth 1 -iregex '.*dll\|exe' | tr '\n' ' ' )

If you would remove the -maxdepth 1, it would become recoursive. Does anyone need that?
