C. Building GrblController for Windows using MinGW

1. Open command window to your GrblHoming folder

2. Enter these two commands:

set QMAKESPEC=C:\Qt\4.8.3\mkspecs\win32-g++

set PATH=%PATH%;C:\Qt\4.8.3\bin;C:\mingw\bin

3. Enter this command:

qmake -config release -spec win32-g++ GcodeSenderGUIthreads.pro

You may see this message twice: “The system cannot find the path specified.” – I think this is ok.

4. Then enter this command:

mingw32-make

You may get the error that it can’t find rcc.exe. Edit Makefile.Release and change

bin\rcc.exe

to this

C:\Qt\4.8.3\bin\rcc.exe

and save

and rerun mingw32-make

Follow this alternate solution borrowed from Daniel, if this occurs when using Qt Creator, which doesn’t create a Makefile. https://bugreports.qt-project.org/browse/QTBUG-27237

a) open the qmake.conf of your platform (for me its C:\Qt\4.8.3\mkspecs\win32-g++)

b) search for QMAKE_IDC

c) add the following line after the QMAKE_IDC line:

QMAKE_RCC = $$[QT_INSTALL_BINS]$${DIR_SEPARATOR}rcc.exe

d) save file and clsoe

e) restart all your dev tools and remove all auto generated Makefiles

f) recompile

5. change into the release subfolder
