As later confirmed, this error comes from using the old Turbo C++ 16-bit toolchain. "SEGMENT_TEXT EXCEEDS 64K" means the linker would have to place more than 64 KB of generated code into a single TEXT (code) segment. That 64 KB cap is a consequence of the 16-bit segmented memory model used by DOS compilers (see segmented memory).

Practical ways to fix it:

  • Change the compiler's memory/code model so code is allowed in multiple segments (look for a "memory model" or "code model" option and choose a model that makes code functions "far" or supports large code). This avoids a single 64 KB TEXT segment.
  • Reduce the code footprint: split very large functions into smaller ones, move big lookup tables or large const arrays out of inline code into separate source files or into data (so they don’t inflate .text).
  • Break the program into multiple modules or use overlays so pieces of code are not linked into one segment.
  • Move away from 16-bit tooling. Using a 32-bit compiler removes this limit — examples are modern GCC/MinGW toolchains or DJGPP if a DOS environment is required (MinGW-w64, DJGPP).

Troubleshooting tips: produce a linker map (or list file) to see which object/module contains the most code, disable aggressive inlining or heavy template expansion, and do a full clean/rebuild after changing models. As noted, the limit is real — but changing model, reorganizing code, or switching to a 32-bit toolchain are the usual, proven remedies.

The best way to solve this would be to uninstall your compiler and turn off your computer.

Leave it off for as long as possible for best results.

Turbo C? Compiling a DOS app?

yes,Turbo C++ compiler,

you cannot have a segment larger 64Kb try different compiler
