(.text+0x20): undefined reference to `main'

[ChoppyThing]

Hi,
i'm trying to run this example to see if it fits my needs. But i'm getting an this error while compiling the example:

Linking... /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function _start':
(.text+0x20): undefined reference to main' collect2: error: ld returned 1 exit status Error: linker exited with status 1 /usr/bin/dmd failed with exit code 1.

Do you have any idea how to solve this ?

Thank you

please upload your program
"(.text+0*20):undefined reference to *" occurs when you need to link explicit libraries to compile program
for example: if you want to compile math.h library function included program
you need to write:
$gcc file_name -o output_file_name -lm
