error: void value not ignored as it ought to be

[Suresh-Subedi]

I am trying to build this basic for arduino uno using platformio. I copied all .ino code to main.cpp. I copied other files in the same src folder with same names. I also added #include <Arduino.h> to all the files. When I compile I encounter following two errors and compilation fails. What could be causing this?

src\main.cpp: In function 'number_t getvar(mem_t, mem_t)':
src\main.cpp:1100:30: warning: invalid conversion from 'mem_t ()(address_t) {aka signed char ()(unsigned int)}' to 'mem_t {aka signed char}' [-fpermissive]

This looks like the header and the interpreter file don't fit together in the repo. I changed the entire getnumber and setnumber logic. Looks like I checked in an inconsistent state. I will check this tonight.

Please try to use basic.h from the Posix folder in the meantime. This should be ok.

I am gettings another error when I use basic.h from Posix folder. I also copied basic.c as it doesn't exist in IotBasic.

src\basic.c: At top level:
src\basic.c:2322:5: error: conflicting types for 'innumber'
int innumber(number_t r, char buffer, address_t k) {
^~~~~~~~
In file included from src\basic.c:35:0:
src\basic.h:517:6: note: previous declaration of 'innumber' was here
char innumber(number_t*,char*);
^~~~~~~~
src\basic.c: In function 'parsestringvar':

[Suresh-Subedi]

If I chage return value to char and add address_t to signature in header, I get:

src\main.cpp:2326:5: error: ambiguating new declaration of 'int innumber(number_t*, char*, address_t)'
int innumber(number_t r, char buffer, address_t k) {

^~~~~~~~
src\main.cpp: In function 'void outnumber(number_t)':

Ok, let me check tonight. I will check in a consistent state. In my local dev environment it works cool.

I fixed this now. basic.h and IotBasic.ino are consistent again. Sorry for the mistake. I change a lot in the types and data structure right now in the 2.0alpha version. In about 2 weeks 2.0 will got beta and be stable again.

Thank you. Unfortunately I still have some errors:

I am using basic.h from IotBasic again. Should I still use basic.h from Posix?

but best use both files from IoTBasic. I have tested this file set.Sent from my iPhoneOn Feb 27, 2024, at 1:01 PM, Suresh Subedi ***@***.***> wrote: I am using basic.h from IotBasic again.

I cloned your repo. Downloaded and installed Arduino IDE and compiled repo in it. It compiled fine. PlatformIO is a bit more quirky and requires methods to be declared before they are used.

src\main.cpp:1348:27: error: too many arguments to function 'void setnumber(address_t, mem_t)'
In file included from src\main.cpp:35:0:

void setnumber(address_t, mem_t);
^~~~~~~~~
src\main.cpp: In function 'address_t createarray(mem_t, mem_t, address_t, address_t)':

I solved this error by placing void setnumber(address_t m, memwriter_t f, number_t v); after includes in main.cpp (IotBasic.ino).

src\main.cpp:1273:30: error: void value not ignored as it ought to be
return getnumber(a, memread2);

setnumber(a, memwrite2, v);
^

While investigating this, I saw that method signature of getnumber doesn't match in basic.h (void getnumber(address_t, mem_t);) and IotBasic.ino (number_t getnumber(address_t m, memreader_t f) {...}). I got further by updating getnumber in basic.h to return number_t. Still encountering other issues though when linking: collect2.exe: error: ld returned 1 exit status.

[slviajero]

Ok! Absolutely correct. These were still the wrong prototypes. My apologies. I now checked in the corrected version. Background info: I changed the entire mem access code and I am still rewriting. I always test first on the Posix code. So this is a remnant of this process.
