bash Script

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
  1. CMakeLists.txt - Generator
  2. This script tries to create a basic CMakeLists.txt from an existing *.pro
  3. qmake-projectfile
  4. 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. $ext\n\
  1. CMakeLists.txt generated from qmake-project $pro #\n\
                                                                                                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=$(egrep "^SOURCES" $prof | sed -e 's/SOURCES//' -e 's/+=//') headers=$(egrep "^HEADERS" $prof | sed -e 's/HEADERS//' -e 's/+=//') forms=$(egrep "^FORMS" $prof | sed -e 's/FORMS//' -e 's/+=//') resources=$(egrep "^RESOURCES" $prof | sed -e 's/RESOURCES//' -e 's/+=//') transl=$(egrep "^TRANSLATIONS" $prof | 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.

Cheers, St0fF

Examples of qmake to CMake conversions?

For people with simple QMake scripts it would be great to have one or more simple examples showing a qmake script and the corresponding CMake script. --Colinb 20:08, 18 March 2010 (UTC)
