| == Converting From Qmake ==
| | {{CMake/Template/Moved}} |
|
| |
|
| Just added to sourceforge: https://sourceforge.net/projects/qmake2cmake/ - this project does a bit more than the ruby-script below.
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/contrib/scripts/ConvertFromQmake here]. |
| | |
| Here is a Ruby script and a shell script which do the "grunt work" of converting a large qmake-based project:
| |
| | |
| <pre>
| |
| #!/usr/bin/ruby -w
| |
| | |
| # Get the file into a string
| |
| file = IO.read(ARGV[0]);
| |
| | |
| # Convert special qmake variables
| |
| projectName = String.new;
| |
| file.sub!(/TARGET = (.+)$/) {
| |
| projectName = $1.dup;
| |
| "PROJECT(#{projectName})"
| |
| }
| |
| templateType = String.new; # We remove the [http://www.diamondlinks.net link builder] project type and stick it at the end
| |
| file.sub!(/TEMPLATE = (.+)$\n/) {
| |
| templateType = $1.dup;
| |
| ""
| |
| }
| |
| file.gsub!(/include\((.+)\)/,
| |
| 'INCLUDE(\1 OPTIONAL)');
| |
| file.gsub!(/includeforce\((.+)\)/,
| |
| 'INCLUDE(\1)');
| |
| file.gsub!(/INCLUDEPATH \*= (.+)((\n[ \t]+.+$)*)/,
| |
| 'SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} \1\2)');
| |
| file.gsub!(/SOURCES \*= (.+)((\n[ \t]+.+$)*)/,
| |
| "SET(#{projectName}_sources $#{projectName}_sources" ' \1\2)');
| |
| file.gsub!(/HEADERS \*= (.+)((\n[ \t]+.+$)*)/,
| |
| "SET(#{projectName}_headers $#{projectName}_headers" ' \1\2)');
| |
| file.gsub!(/DEFINES \*= (.+)((\n[ \t]+.+$)*)/,
| |
| 'SET(DEFINES ${DEFINES} \1\2)');
| |
| | |
| # Now deal with other variables
| |
| file.gsub!(/(.+)\s\*=\s(.+)/,
| |
| 'SET(\1 ${\1} \2)');
| |
| file.gsub!(/(.+)\s=\s(.+)/,
| |
| 'SET(\1 \2)');
| |
| file.gsub!(/\$\$\{(.+)\}/,
| |
| '${\1}');
| |
| file.gsub!(/\$\$\((.+)\)/,
| |
| '$ENV{\1}');
| |
| file.gsub!(/([A-Za-z_\-.]+)\.pri/,
| |
| '\1.cmake');
| |
| | |
| # Cleanup steps
| |
| file.gsub!(/\\\)/, ')');
| |
| | |
| # Put the project type back in
| |
| file += "ADD_EXECUTABLE(#{projectName} #{projectName}_sources)" if templateType == "app";
| |
| file += "ADD_LIBRARY(#{projectName} ${#{projectName}_sources})" if templateType == "lib";
| |
| | |
| # Write the new file to CMakeLists.txt
| |
| if ARGV.length > 1
| |
| outname = ARGV[1];
| |
| else
| |
| if ARGV[0] =~ /.+\.pro$/
| |
| outname = File.join(File.dirname(ARGV[0]), "CMakeLists.txt");
| |
| elsif (ARGV[0] =~ /.+\.pri$/) || (ARGV[0] =~ /.+\.prf$/)
| |
| outbase = File.basename(ARGV[0]);
| |
| outbase.sub!(/\.pr./, ".cmake");
| |
| outname = File.join(File.dirname(ARGV[0]), outbase)
| |
| end
| |
| end
| |
| outfile = File.new(outname, "w");
| |
| outfile.puts(file);
| |
| outfile.close;
| |
| </pre>
| |
| | |
| So you have a script to convert a single file. Now you need one to recurse a directory tree:
| |
| | |
| <pre>
| |
| #!/bin/sh
| |
| for file in `find . -name '*.pr?'`; do
| |
| dos2unix $file
| |
| filetype=`echo $file |sed -e 's/.*\.\(pr.\)/\1/'`
| |
| path=`dirname $file`
| |
| base=`basename $file`
| |
| if [ -e "$path/CMakeLists.txt" -a "$filetype" = "pro" ]; then
| |
| ./qmake2cmake.ruby $file $path/CMakeLists-$base.txt
| |
| else
| |
| ./qmake2cmake.ruby $file
| |
| fi
| |
| done
| |
| </pre>
| |
| | |
| It's hardly complete, but it's a lot better than doing the whole thing by hand!
