    The “Undermined Comment” error occurred when my partner and I did not end a comment with a valid encoding. A single-line comment does not have to end and start with another double slash (//), but multiple web comments must end with */ (an asterisk and a forward slash).

    False “Error: comment not closed”

    I’m drafting this bug as if gfortran would normally look for the end of your own C-style comment.
    Files consist of a fixed contact form and a comment ending only in “/*”.

    I tried to enter my purchase reduction test case under m_comment.for on Linux and failed to multiply the error.

    It may be obvious that there are line endings in RFLCT.FOR even if there are none in subm_comment.for.

    No, that’s not possible. The problem is that RFLCT than .FOR has an uppercase .FOR
    extension that tells gfortran to require C-style preprocessing, whereas a file with .for
    does not repeat lowercase. C-style preprocessing rather than C-style preprocessing is advantageous with /* and */. Some compilers can handle this (Intel, Sun), but not
    (g95, only some Gfortran).

    This could be a flashy RFLCT where .FOR contains line endings but unterm_comment.for does not.

    The problem is that most CPP preprocessors do not support Fortran mode. In Fortran mode, comment lines/search comments are completely
    ignored and // also not evaluated as comment characters. See also bug report PR 28662.

    What is unterminated comment error in C language?

    Comments are used to write logic or explain products that you don’t want to compile. There are two types of comments in C language: 1) single line comment and 2) multiline comment. The “Undermined Comment” error occurred when consumers did not complete the comment with a valid character set.

    No, not only that. The problem with the RFLCT is that .FOR has an uppercase .FOR
    extension which tells gfortran to require C-style preprocessing if it doesn’t support a file with a .for<.br>lowercase extension .

    It is important that RFLCT.FOR has feedback and unterm_comment.for does not.

    I’m getting this error because gfortran would like to get a C
    -style end of statement. Files have a fixed form and a comment ending
    in “/*”.
    I typed my own test with limited circumstances under m_comment.for on Linux
    and could not reproduce the error.
    You may notice that RFLCT.FOR has do-line endings, while
    unterm_comment.for does not. In

    Adding the most relevant previous answers, the receipt line option “-x
    f95 -ffixed-form” may solve your problem.
