ld returned 1 exit status

This error message is typically seen when compiling a C or C++ program using a linker. It indicates that the linker failed to properly link the object files together to create the final executable. The "1" in the error message typically refers to the fact that one or more errors were encountered during the linking process.

There are many possible causes of this error, including missing or incorrect library references, syntax errors in the source code, and problems with the linker itself. To diagnose the problem, you may need to examine the linker command line, the object files being linked, and the source code for any syntax errors.

Once you have identified the cause of the error, you can take steps to fix it. This may involve adding missing library references, correcting syntax errors, or modifying the linker command line to include additional options or libraries. In some cases, it may also be necessary to update the linker itself or switch to a different linker.
