Talk:CMake:ConvertFromQmake

Hi!

I'm sorry to say that, but for me the ruby-script didn't work at all. But I don't talk ruby, so I wrote a simple bash-script to do the grunt work for a simple qmake-project. Here it comes, I hope you find it useful... it requires what most bash-scripts require: sed, awk, grep, and ofcourse cmake...

<source lang=bash>

1. !/bin/bash

3. CMakeLists.txt - Generator
5. This script tries to create a basic CMakeLists.txt from an existing *.pro
6. qmake-projectfile
7. Parameters: $1 = projectfile

prof=$(basename $1) odir=$CWD cd $(dirname $1) pro=${prof/\.pr?/} out=CMakeLists.txt

ext="" for ((i=0; i<${#pro} ; i++)) ; do ext="${ext}#" ; done rm $out echo -e "\

1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. $ext\n\
2. CMakeLists.txt generated from qmake-project $pro #\n\
   1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. $ext\n" >> $out

echo "# ... Project setup ..." >> $out echo "project($pro)" >> $out mive=$(cmake --version | sed 's/[a-zA-Z\s-]*//g' | awk '{print $1}') echo "cmake_minimum_required(VERSION $mive)" >> $out

1. we've got a qmake project, so I guess we need to link QT
2. -> we'll need CMP0003 directive ...

echo -e "if(COMMAND cmake_policy)\n\ \tcmake_policy(SET CMP0003 NEW)\nendif(COMMAND cmake_policy)\n" >> $out

1. Now let's not care about what really stands in "CONFIG", just use alot...

echo -e "\

1. ########## Qt4 setup ##########\n\

FIND_PACKAGE(Qt4 REQUIRED)\n\ INCLUDE(\${QT_USE_FILE})\n\ INCLUDE_DIRECTORIES(\${CMAKE_SOURCE_DIR} \${QT_INCLUDES})\n\ ADD_DEFINITIONS(-DQT_GUI_LIBS -DQT_CORE_LIB)\n" >> $out

1. finally we could traverse the qmake project file ...

sources=$(cat $prof | grep -e "^SOURCES" | sed -e 's/SOURCES//' -e 's/+=//') headers=$(cat $prof | grep -e "^HEADERS" | sed -e 's/HEADERS//' -e 's/+=//') forms=$(cat $prof | grep -e "^FORMS" | sed -e 's/FORMS//' -e 's/+=//') resources=$(cat $prof | grep -e "^RESOURCES" | sed -e 's/RESOURCES//' -e 's/+=//') transl=$(cat $prof | grep -e "^TRANSLATIONS" | sed -e 's/TRANSLATIONS//' -e 's/+=//')

echo -e "# Source files\nSET(SRCS\n\t$sources\n)\n" >> $out echo -e "# Header files\nSET(HDRS\n\t$headers\n)\n" >> $out if [ -n "$resources" ] then echo -e "# Resource files\nSET(RSCS\n\t$resources\n)\n" >> $out fi if [ -n "$transl" ] then echo -e "# Translation files\nSET(TRANS\n\t$transl\n)\n" >> $out fi

final=""

if [ -n "$forms" ] then # Forms is not empty - we need the uic-wrapper and a moc wrapper echo -e "# UI files\nSET(UIS\n\t$forms\n)\n" >> $out

# if we have forms, we will also need the moc wrapper. But what are # the moc-files? Just running moc on the Header files and inspecting # the output for error-messages should suffice ;) mocs="" for head in $headers do moc $head 1> /dev/null 2> __erg__ erg=$(cat __erg__) if [ -z "$erg" ] # nothing recorded - no error -> do it! then mocs="$mocs $head" fi done if [ -n "$mocs" ] then echo -e "# Headers to be moc'ed ...\nSET(MOCH\n\t$mocs\n)\n" >> $out echo -e "# MOC-wrapper for Metadata stuff\nQT4_WRAP_CPP(MOC \${MOCH})\n" >> $out final="$final \${MOC}" fi

echo -e "# UIC-wrapper for used forms\nQT4_WRAP_UI(UI_H \${UIS})\n" >> $out final="$final \${UI_H}" fi

if [ -n "$transl" ] then echo -e "# add translations ...\nQT4_ADD_TRANSLATION(QM \${TRANS})\n" >> $out final="$final \${QM}" fi

if [ -n "$resources" ] then # Resources are not empty - so lets add them echo -e "# add Resource files ...\nQT4_ADD_RESOURCES(QRC \${RSCS})\n" >> $out final="$final \${QRC}" fi

echo -e "# And now - for the final steps ...\n\ ADD_EXECUTABLE($pro \${HDRS} \${SRCS}$final)\n\ TARGET_LINK_LIBRARIES($pro \${QT_LIBRARIES})\n\n# finally the installer\n\ INSTALL(TARGETS $pro DESTINATION bin)" >> $out

rm __erg__ cd $odir </source>

I hope you find it useful. For very simple QMake-Projects it probably works better than the ruby-example. Maybe you'll add it to the wiki as I don't feel to have the right to do that.
