Hello, I've just installed the new MPLAB v8.80, coming from v8.76. --- I now get a lot of errors, e.g.: In file included from c:\utility\electronics\mplab\mplab c32 suite\bin\../l= ib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/peripheral/dma.h:40:0, from c:\utility\electronics\mplab\mplab c32 suite\bin\../l= ib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/plib.h:45, from v001_C.C:22: c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/dma_3xx_4xx.h:827:19: error: '_DMACON= _FRZ_MASK' undeclared here (not in a function) In file included from c:\utility\electronics\mplab\mplab c32 suite\bin\../l= ib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/plib.h:56:0, from v001_C.C:22: c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/rtcc.h: In function 'RtccFreezeEnable= ': c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/rtcc.h:1323:13: error: '_RTCCON_FRZ_M= ASK' undeclared (first use in this function) c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/rtcc.h:1323:13: note: each undeclared= identifier is reported only once for each function it appears in c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/rtcc.h: In function 'RtccGetFreeze': c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/rtcc.h:1351:19: error: '__RTCCONbits_= t' has no member named 'FRZ' In file included from c:\utility\electronics\mplab\mplab c32 suite\bin\../l= ib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/peripheral/spi.h:44:0, from c:\utility\electronics\mplab\mplab c32 suite\bin\../l= ib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/plib.h:57, from v001_C.C:22: c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/spi_3xx_4xx.h: At top level: c:\utility\electronics\mplab\mplab c32 suite\bin\../lib/gcc/pic32mx/4.5.1/.= ../../../../pic32mx/include/peripheral/spi_3xx_4xx.h:139:1: error: '_SPI1CON= _FRZ_MASK' undeclared here (not in a function) Halting build on first failure as requested. --- Any clue? Past MPLAB updates, loading the same Workbench, didn't result in = any problems.
