Hi,
I am upgrading a product from MQX 4.0.1 to 4.1.0.1 and I think I may have come across a bug.
My understanding was that in order to enable a feature, you simply defined the feature's 'enable' define to 1 in the user_config.h.
I am using PPP in my project, so I defined RTCSCFG_ENABLE_PPP to 1, but the feature wasn't included.
On investigation it appears that the
#if RTCSCFG_ENABLE_PPP
lines in lots of files (ppp.c, pppfsm.c, pktrx.c, pkttx.c etc) is before any of the includes. This means that there is no way for the user_config ( and the 'enable' define ) to be included when these objects are compiled.
I have two options to make this work:
1) Move the #if in each file (which is what I chose)
2) Add -D RTCSCFG_ENABLE_PPP=1 to the compile flags.
Is this a mistake, or is the intention that compile flags now be used rather than the user_config?
Either way, I figured this observation would be useful for anyone else that can't figure out why it's not working.
