The command line is important for g95 . Therefore , please write a complete
command line for compilation . Since these are multi-platform software AND
different platforms are NOT equivalent in their directory structure , I
think , these facts are not very important points .


My approach is to use a batch file in Windows and a shell script in Linux to
compile programs  :

For example : g95-cte.sh ( cte : compile to executable , there is another
cts : compile to syntax  )


g95 -ftrace=full -o $1 $1.FOR


( -ftrace=full means , generate code to produce call chain trace on run-time
error . )
To compile  a program , use it as follows ( use your extension as it is :
.for or .FOR , FreeBSD is case-sensitive ) :


g95-cte.sh hello


Move g95-cte.sh after making it executable into a directory which it is in
the $PATH , then it will be possible to use g95-cte.sh from any directory .

For specially required directories , add their names into its command line
with suitable prefixes .


In the following page ,
http://www.g95.org/downloads.shtml


there are binaries for FreeBSD . Since they are specific to platforms , they
MAY NOT require specification of libraries , but , again , these are NOT
important , specify them in shell script command line only one time ,
then use it continuously .

Thank you very much .
