Issue with cstdint header(after fixes #27)

[ZanderCai]

Hello Martin,

We are at Columbia MPlab and tried to use the recent version of the library(before the version of Fixes #27 ), and faced an issue with #cstdint header. (The mcu what we use is Texas Instructment C2000, TMS320F28377S LaunchPad with IDE Code Composer Studio and newest version of C2000 Compiler V21.12.0.) #include <cstdint> Here is the related error message: >> Compilation failure subdir_rules.mk:16: recipe for target 'DataObjectNew.obj' failed "C:/ti/thingset_device_library/src/thingset.h", line 18: fatal error #1965: cannot open source file "cstdint" 1 catastrophic error detected in the compilation of "../DataObjectNew.cpp". Compilation terminated.

At first , we believed this is a smilar issue as Fixes #27 , so we applied the Fixes. After that, the follwing error about "uint8_t" poped out: >> Compilation failure subdir_rules.mk:16: recipe for target 'DataObjectNew.obj' failed "C:\ti\thingset_device_library\src\cbor.h", line 73:

C2000 Compiler V21.12.0 compiler should compile C and C++. Our code has both C and C++ with main function file as .C file. Do you have any idea about how to fix this issue?

Thanks so much for help,

That looks strange, as uint8_t should be defined in stdint.h: https://en.cppreference.com/w/c/types/integer

Maybe it's a problem of the C2000 compiler. So I'm sorry that I don't have a good idea for a fix right now.

[jalinei]

Maybe you can replace all uint8_t with uint16_t ? Would it mess everything up ?

[ZanderCai]

Hello, everyone, just quick update from our side. We tried #define uint8_t uint16_t, and those "uint8_t" is not a type name error was gone. Pls don't close the case right now. We still need to work on it and not sure whether any future error will be encountted base on the fix what we do so far. We'll keep updating. Thanks!

Luiz shared this link with me: https://software-dl.ti.com/ccs/esd/documents/c2000_byte-accesses-with-the-c28x-cpu.html

At first I thought that must be a joke, but it really seems that TI defines a byte with 16 bit. This reminded me of this funny talk I recently watched where they suggest to define integers as 17-bit (leaving remaining 15 bits unused) to increase revenue of memory companies.

So, yeah, this library probably only works for ISO C compliant compilers / platforms. If the hack with #define uint8_t uint16_t works properly, that would be surprising. Let me know your testing result.
