We don't know what operating system, what programming language or what compiler you are using.
We have no idea what code it is you had that failed to compile, we have no idea what changes you made.
So we're in more of the dark than you.

INTERCAL::ByteCode(3pm) User Contributed Perl Documentation INTERCAL::ByteCode(3pm)
TITLE
Language::INTERCAL::Bytecode - intermediate language
DESCRIPTION
The CLC-INTERCAL compiler works by producing bytecode from the program source; this bytecode can be interpreted to execute the program
immediately; alternatively, a backend can produce something else from the bytecode, for example C or Perl source code which can then be
compiled to your computer's native object format.
The compiler itself is just some more bytecode. Thus, to produce the compiler you need a compiler compiler, and to produce that you need a
compiler compiler compiler; to produce the latter you would need a compiler compiler compiler compiler, and so on to infinity. To simplify
the programmer's life (eh?), the compiler compiler is able to compile itself, and is therefore identical to the compiler compiler compiler
(etcetera).
The programmer can start the process because a pre-compiled compiler compiler, in the form of bytecode, is provided with the CLC-INTERCAL
distribution; this compiler compiler then is able to compile all other compilers, as well as to rebuild itself if need be.
See the online manual or the HTML documentation included with the distribution for more information about this.
