IMPORTANT

For beta 6 support PICBASIC PRO and CCSC was added. However, support to import an MPLAB 8 project using this compilers is not there yet. You need to recreate the projects using the "Standalone Project" wizard.
Also, to use the PICBASIC PRO, you might need to add mpasmx to your path: add $InstallationDir\mpasmx. For example, if you installed to the default MPLAB X installation directory in a 32 bit Windows system, you'd need this in your path:
C:\Program Files\Microchip\MPLABX\mpasmx

Do this if you get the error:
ERROR: Unable to execute mpasmx.make[2]:

If you change your path, you need to re-start MPLAB X.
