README of copydlldeps.sh
========================
This document belongs to copydlldeps.sh and is a part of the MXE project.
It can be invoked 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 )
sharedLibsDir="${orgDir}/nsis/sharedLibs"
echo "populating dir $sharedLibsDir with dll dependencies of $executable" | tee -a $CURLOG
OBJDUMP=objdump
if [ -e "$MXEPATH/usr/bin/$compiler-objdump" ]; then
OBJDUMP="$MXEPATH/usr/bin/$compiler-objdump"
fi
$MXEPATH/tools/copydlldeps.sh --infile $executable \
--destdir "$sharedLibsDir" \
--recursivesrcdir "$MXEPATH/usr/$compiler/" \
--enforce "$MXEPATH/usr/$compiler/qt5/plugins/platforms/" \
--copy \
--objdump "$OBJDUMP" \
| tee -a $CURLOG
fi
```
Additional hints
================
objdump
-------
I checked if there is a mxe objdump. If not, I took the native one on my server.
I actually do not know the difference but decided to include it in the script
in case it is important to someone.
enforce
-------
My application is using Qt5 and objdump did not return the needed qwindows.dll -
so I enforce the platform folder. You may add multiple --enforce directories using
`--enforce /path/folder1 --enforce /path/folder2 --enforce /path/folder3`.
They are NOT recursively copied, only flat. See:
```bash
string=$( find $enforcedDirectory -maxdepth 1 -iregex '.*\(dll\|exe\)' | tr '\n' ' ' )
```
If you would remove the `-maxdepth 1`, it would become recoursive.
