gcc - Changing compiler in Qt -



gcc - Changing compiler in Qt -

how alter compiler (gcc) in qt? i've installed gcc 4.4 , 4.6. @ momment qt uses 4.4 i'd utilize 4.6. how it?

in build sequence may have qmake command qmake yourproject.pro -r -spec linux-g++-64 selection of tool chain done in spec file here linux-g++-64. find file in path-to-the-sdk/qt/mkspecs/linux-g++-64 (you concept right?)... if open spec file see includes linux spec , g++ spec.

one solution re-create g++ spec file , rename g++-4.6 illustration edit , alter :

qmake_cc = gcc qmake_cxx = g++

to :

qmake_cc = gcc-4.6 qmake_cxx = g++-4.6

idem linux-g++-64 can copied linux-g++-4.6-64 , modify include(...) command include new g++-4.6 file.

finally build project qmake yourproject.pro -r -spec linux-g++-4.6-64.

i hope it's clear :) ...

qt gcc
