Qt + boost build integration

August 22, 2016

Sometimes it is good to be able to include boost library without need to compile the whole package beforehand - just by including simple .pri file like this:

# Wed Aug 24 09:21:20 CEST 2016
INCLUDEPATH += $$PWD/.

SOURCES += 
 "$$PWD/libs/regex/src/c_regex_traits.cpp" 
 "$$PWD/libs/regex/src/cpp_regex_traits.cpp" 
 "$$PWD/libs/regex/src/cregex.cpp" 
 "$$PWD/libs/regex/src/fileiter.cpp" 
 "$$PWD/libs/regex/src/icu.cpp" 
 "$$PWD/libs/regex/src/instances.cpp" 
 "$$PWD/libs/regex/src/posix_api.cpp" 

win32:SOURCES +=

unix:SOURCES += 

LIBS += -lz -lbz2

Here is a simple script that generates boost-mpi.pri script and set of headers and sources from Boost library located at /Volumes/USBSTORE/(Dev)/boost_1_61_0 path:

#!/bin/bash
OUT=.
PRI=boost-mpi.pri

/opt/local/bin/bcp \
    --boost=/Volumes/USBSTORE/(Dev)/boost_1_61_0 \
    boost/mpi.hpp \
    boost/compute.hpp \
    $OUT/
#
# build Qt include file:
#
echo "#" `date` > $PRI
echo "INCLUDEPATH += $$PWD/$OUT" >> $PRI
# exclude files that donot compile:
#   shared_ptr_helper.cpp
files=""
dedups() {
    eval local ff=$$1
    local F=`basename $ff &#124; sed 's/(.*)..*/1/'`
    case "$files" in
        *";$F"* )
            local DIR=`dirname "$ff"`
            local EXTENSION=${f##*.}
            local fn="$DIR/$RANDOM-`basename "$ff"`"
            echo "duplicate: $ff -> $fn"
            mv "$ff" "$fn"
            ff="$fn"
            ;;
        * )
            files="$files;$F"
            ;;
    esac
    eval $1="$ff"
}
if [ -e $OUT/libs ]; then
    echo "SOURCES += " >> $PRI
    for f in `find $OUT/libs -iname "*.cpp" ! -iname "shared_ptr_helper.cpp" 
        -path "*/src/*" ! -path "*/test/*" ! -path "*/win32/*" ! -path "*/pthread/*" | xargs`; do
        dedups f
        echo "  "$$PWD/$f" " >> $PRI
    done
    echo "" >> $PRI
    echo "win32:SOURCES += " >> $PRI
    for f in `find $OUT/libs -iname "*.cpp" ! -iname "shared_ptr_helper.cpp" 
        -path "*/src/*" ! -path "*/test/*" -path "*/win32/*" | xargs`; do
        dedups f
        echo "  "$$PWD/$f" " >> $PRI
    done
    echo "" >> $PRI
    echo "unix:SOURCES += " >> $PRI
    for f in `find $OUT/libs -iname "*.cpp" ! -iname "shared_ptr_helper.cpp" 
        -path "*/src/*" ! -path "*/test/*" -path "*/pthread/*" | xargs`; do
        dedups f
        echo "  "$$PWD/$f" " >> $PRI
    done
    echo "" >> $PRI
    echo "LIBS += -lz -lbz2" >> $PRI
fi
wc -l $PRI

PS. Sometime it is necessary to add boost/system/error_code.cpp file to the bap’s list of files to resolve some linking issues.
