I want to import a project for the MCB1700 onto my LCP1769 and I am getting like 130 warnings. Why could that be? I think I loaded the right packs.

I am getting like 130 warnings
Usually this is just one or 2 basic errors which lead to multiple follow-on errors.
eg
C:/Keil_v5/ARM/PACK/Keil/LPC1700_DFP/2.6.0/RTE_Driver/EMAC_LPC17xx.h(59): warning: 'RTE_ENET_MII' is not defined, evaluates to 0 [-Wundef] #if (RTE_ENET_MII && RTE_ENET_RMII) ^ C:/Keil_v5/ARM/PACK/Keil/LPC1700_DFP/2.6.0/RTE_Driver/EMAC_LPC17xx.c(96): warning: 'RTE_ENET_MII' is not defined, evaluates to 0 [-Wundef] #if (RTE_ENET_MII) ^ C:/Keil_v5/ARM/PACK/Keil/LPC1700_DFP/2.6.0/RTE_Driver/EMAC_LPC17xx.c(136): warning: 'RTE_ENET_MII' is not defined, evaluates to 0 [-Wundef] #if (RTE_ENET_MII) ^
all three of those are the same problem.
Looks like you've omitted some configuration setting.
The secret is always to address the earliest-reported error first.
import a project
What, exactly, do you mean by that?
Did the original program build cleanly (ie, with no warnings) ?
What, exactly, did you do to "import" it?
Always good to specify the compiler used and DFP version.
This is ARMCLANG being correct about issues with the middleware. Which is part of the blessing/curse of Keil's PACK system: it seems that arm/Keil are releasing compiler versions faster than the DFP teams can test and update.
For example, looking at the very first warning: RTE_Device.h configured for an LPC176x device defines RTE_ENET_RMII but does not define RTE_ENET_MII. Then ARMCLANG complains about the undefined macro RTE_MNET_MII in the test defined in the middleware headers because the header is using an old-school test for 'is defined'. If you use the Keil IDE "out of the box" to use and configure Ethernet for an LPC176x-based board like the MCB1700 you cannot avoid these warnings. (How to best fix errors in EMAC_LPC17xx.c?)
Well I just opened a project from someone else. I don't know if "to import" is the right term here. Seems like there is something missing in the RTE_Device.h. I have #define RTE_ENET_RMII 1, but no RTE_ENET_MII. Adding it just led to more warnings though
Well if I can't do something about it I will just leave them
Adam Lins said:the header is using an old-school test for 'is defined'.
Actually, it is just assuming that it is defined - and testing its value.
There should be a #ifdef or a #if defined before that.
