Fixing undefined reference to ‘sqrt’ in Linux
This is a common error while compiling C program in GCC/G++ Linux. This error occurs when you are using sqrt function to find square root of a number in your programs.
How do you fix undefined reference error?
So when we try to assign it a value in the main function, the linker doesn’t find the symbol and may result in an “unresolved external symbol” or “undefined reference”. The way to fix this error is to explicitly scope the variable using ‘::’ outside the main before using it.

What does undefined reference to main mean?
The error: undefined reference to ‘main’ in C program is a very stupid mistake by the programmer, it occurs when the main() function does not exist in the program. If you used main() function and still the error is there, you must check the spelling of the main() function.
How do you write sqrt in C?
…
- Declare an integer variable, as num.
- Use the sqrt() function to pass the num variable as an argument to find the square root.
- Print the result.
- Exit or terminate the program.
How do you solve undefined reference to POW in C?
otherwise you will get undefined reference to pow error, when you compile below program with no -lm option. To fix this issue, need to use -lm option in compilation command. C program provides expected output when running a. out file once you compiled the program with -lm option.
How use sqrt function in C Linux?
All you need to do is to use a cast operator to convert the type of double. To work with float numbers simply use the “sqrtf()” function and if you want to deal with long double type then use “sqrtl()”. If you enter any negative value as an input, then the function sqrt() in C shows a domain error.

what is an undefined symbol error? It means you haven’t written a function, or you haven’t created a variable, or you haven’t linked against the library or object code that contains the missing function or variable.
How do I fix linker error?
You can fix the errors by including the source code file that contains the definitions as part of the compilation. Alternatively, you can pass . obj files or . lib files that contain the definitions to the linker.
What is WinMain error?
This error means that the linker is looking for a function named WinMain to use as the entry point. It would be doing that because you configured the project to target the GUI subsystem, but did not provide a WinMain function.

Why sqrt function is used?
The SQRT function is one of the math and trigonometry functions. It is used to return the square root of a number. where x is a numeric value entered manually or included into the cell you make reference to.
How does sqrt function work?
SQRT is similar to the POWER function. However, the POWER function works like an exponent in a standard math equation. For example, for the number 25, we will provide the formula =SQRT(25) and =POWER( 25, 1/2).
What is the square root formula?
What is the Formula for Calculating the Square Root of a Number? The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.
Why is pow function not working in C?
On some online compilers, the following error may occur. The above error occurs because we have added “math. h” header file, but haven’t linked the program to the following math library. Link the program with the above library, so that the call to function pow() is resolved.
How do you write POW in C?
pow() is function to get the power of a number, but we have to use #include<math. h> in c/c++ to use that pow() function. then two numbers are passed. Example – pow(4 , 2); Then we will get the result as 4^2, which is 16.
What is Pow C?
C pow() The pow() function computes the power of a number. The pow() function takes two arguments (base value and power value) and, returns the power raised to the base number. For example, [Mathematics] xy = pow(x, y) [In programming] The pow() function is defined in math.
How do you find the square root of a number without using sqrt function in C?
if you need to find square root without using sqrt() ,use root=pow(x,0.5) .
What is the return type of the function sqrt () in C?
The SQRT function returns the square root of a floating-point number; only the built-in types REAL, FLOAT, and DOUBLE PRECISION are supported. The return type for SQRT is the type of the parameter. Note: To execute SQRT on other data types, you must cast them to floating-point types.
How do I link my math library to gcc?
To link in these libraries, use -lname. For example, the math library is in the file /usr/lib/libm.so (and the static version of the library is in /usr/lib/libm. a). To link the math library into your program you include -lm on the gcc command line (as in the example above).
What is undefined reference to printf?
Undefined reference to printf when using GCC cross compiler (4) The x variable is there to stop GCC changing printf to puts , which it seems to do automatically for a simple newline-terminated string. I’m assuming this is a problem with the linker, as I’d expect the process to fail earlier if for example stdio.

How do you use extern?
the extern keyword is used to extend the visibility of variables/functions. Since functions are visible throughout the program by default, the use of extern is not needed in function declarations or definitions. Its use is implicit. When extern is used with a variable, it’s only declared, not defined.
How do you pass a value by reference in C++?
Pass-by-reference means to pass the reference of an argument in the calling function to the corresponding formal parameter of the called function. The called function can modify the value of the argument by using its reference passed in. The following example shows how arguments are passed by reference.
