Leboffe & Pierce in their text "Microbiology Laboratory Theory and Application" (second edition) state on page 111 that PEA is an undefined medium

You are probably trying to build a dynamic library. If so, do not use ld, use CC -g instead.

In JavaScript undefined is a special value used when a variable has not had a value set to it, or has not been declared.

Linker errors are many and varied. Without knowing the error it is impossible to say how you solve it. Most linker errors relate to undefined symbols. For instance, if you declare a function but do not implement it, the function is undefined. This can also happen when you include a function library header but do not link to the function library containing the definitions. The compiler uses the header declarations to ensure all calls to the functions are valid even if the definition hasn't yet been compiled. It is the linker's job to ensure all declarations are defined. The only exception is templates which must be defined before they are used. This is why all template definitions are placed in the header alongside the declarations.

Undefined.
A term that is undefined mean simply that it is not defined. The prefix un means not, and if you add it to the word defined, ta da, you get undefined.
"Defined items" are defined in terms of "undefined terms".

A set can be defined or undefined.
"Defined items" are defined in terms of "undefined terms".
It's complex because the constituent elements of the medium (enzymatic digests of casein and soybean) are present in an undefined amount, and an amount which will vary from batch to batch. Contrast this to a chemically defined medium which will always contain the exact amount of constituent.
Zero is pretty well defined. Division by zero is undefined.
EMB is an undefined selective/differential medium. It contains aniline dyes (methylene blue and eosin), which inhibit the growth of Gram-positive bacteria selecting for Gram-negative bacteria. EMB also contains lactose which makes the media differential based on an organisms ability to ferment lactose
There are two main classifications of culture medianamely defined and undefined. An undefined culture mediumcontains a basic source of aminoacids and nitrogen which are the essential requirements for growth of microorganisms. Common examples of the constituents are beef and yeast extracts. The exact composition and percentage of the individual amino acid or nitrogen providing source is unknown and this is used for basic culture and maintenance of strains. An undefined medium is also called a basal or complex medium. In addition to the aminoacid and nitrogen source it also contains a source for glucose, water and other essential salts.A defined culture medium or synthetic medium is one that contains salts and a glucose source and other components based on the requirements of culture. It contains no yeast or animal extracts. Each of the components used are accurately weighed and the percentage known.
This type of agar is designed to grow gram-negative bacteria. It will not grow gram-positive bacteria due to a dye in the formula of the agar.
