Can't build NXP IMXRT1020 + FreeRTOS + LWIP in MCUXPresso IDE

[GanesanGuru]

Hi team,
I'm referring this, and following Option 2 - MCUXpresso IDE.. Done as mentioned. After importing project - when went for building, I'm getting this following error. Please explain the where did I went wrong..

I'm sorry, I'm not able to guess what "this error" means, I see a snapshot of a screen full of unrelated errors. Please be specific, and please try to spare snapshots, compilers output text and humans do read text

HI @scaprile ,
Lot of basic variables like AF_NET,bool,false,etc are not able to be identifed by the compiler. Being the simple imported project to the suggested IDE, why it happens so @scaprile ?

[scaprile]

No, it is not.
What I see is this:

That example pulls an example from an external repository. The NXP project file for that example in that external repository has not been updated to the latest Mongoose definitions, and so Mongoose is looking for a configuration file.
This: -DMG_ARCH=MG_ARCH_FREERTOS_LWIP is outdated. As you can see in the Makefile that you surely run in option 1, the new definitions are: -DMG_ARCH=MG_ARCH_FREERTOS -DMG_ENABLE_LWIP=1, so you have to change Project -> Properties -> C/C++ Build -> Settings -> MCU C Compiler -> Preprocessor to reflect that

We'll contact the foreign repo maintainer.

Hi @scaprile ,
That's really great. All those errors has been reolved widely. Yet, I'm getting the following error..
../source/mongoose.h:197:46: error: unknown type name 'mode_t'
which directs to mongoose.h file's 197th line funtion definition --> "static inline int mg_mkdir(const char *path, mode_t mode) {"

Any suggestions for resolving this one @scaprile ?!

[GanesanGuru]

Resolved by adding #include <sys/stat.h>. Thanks @scaprile for your guidance...
