I made some changes and now getting a linking error but it makes no sense

tjodork · November 8, 2022, 4:02am

The error is when it links and it says
"C:\Users\timoc\Documents\Arduino\simpleMesh6\simpleMesh6/simpleMesh6.ino:173: undefined reference to `_Z8tag_nodev'
collect2.exe: error: ld returned 1 exit status"

Note I have an earlier version prior to some logic changes and it compiles fine

Any suggestions?

In such a case I very carefully compare the earlier version with the later version, and scrutinize every single change.

If that doesn't identify the culprit, start over from the earlier version and introduce the changes one by one, making sure after each change that the result compiles without errors. The second time around is always faster.

Thanks for the quick response... i was already attempting what you suggested and found that I was inconsistent on a function call tag_node() I should have passed an integer...but sometimes i did not.
The error msg was so divorced from the issue but your recommendation was spot on...but once consistent it did compile !

johnwasser · November 8, 2022, 2:50pm

The trick is that 'overloaded' functions (functions with the same name but different arguments) are given different names for linking purposes. The error message said that the linker could not find "_Z8tag_nodev". That would be a version of "tag_node". I looked at the code and saw that the prototype for tag_node() was:
void tag_node();
But down at the actual declaration it's:
void tag_node(int mode) {
That was enough to cause the error. You told the compiler that somewhere there was a void tag_node(void); so that's what it called but the linker couldn't find it because you only declared a void tag_node(int);

WOW, thanks for explaining that...it makes a LOT more sense... Really appreciate it !
