fortran - ifort 行长度限制

Question

所以似乎有一些关于 gfortran 的线宽限制的问题，但没有一个关于 ifort 的问题。我在编译时遇到以下问题:

../../../src/70_gw/gwls_lineqsolver.F90(298): error #5082: Syntax error, found IDENTIFIER 'ENDIF' when expecting one of: ( * ) :: , <END-OF-STATEMENT> ; + . - (/ [ : ] /) ' ** / // > ...
&"        endif
----------^
../../../src/70_gw/gwls_lineqsolver.F90(298): error #6404: This name does not have a type, and must have an explicit type.   [ENDIF]
&"        endif
----------^

             write(std_out,*) "              subspace (the kernel contains state i=",min_index," > ",nbandv,"=# of valence states).&
------------------------------------------------------------------------------------------------------------^
../../../src/70_gw/gwls_lineqsolver.F90(290): error #6321: An unterminated block exists.

^

make[3]: *** [gwls_lineqsolver.o] Error 1

触发错误的实际代码如下:

if (project_on_what==1 .and. (min_index > nbandv)) then
             write(std_out,*) " "
             write(std_out,*) "              There is a projection on the conduction states, but A is singular in this "
             write(std_out,*) "              subspace (the kernel contains state i=",min_index," > ",nbandv,"=# of valence states)."
end if

我没有一个 gfortran 编译器来测试它，但我相信我会因为行长度限制而得到这个。 ifort 中是否有标志可以取消此限制？

该错误可能是由 ifort 11.x ( Source ) 中的错误引起的:

Beginning with the 11.x release, the Intel Fortran compiler does not correctly ignore the -extend-source (and other variants) for free-form source files named with the .F90 extension. The option is correctly ignored for source files named with the lower-case .f90 extension.

The mishandling of the option will cause erroneous syntax errors for any Fortran source statement that extends beyond the designated statement field length specified with the -extend-source option.

通过将文件扩展名更改为 .f90 并添加标志 -fpp 以保持预处理，可以轻松避免该错误。
