g77 : problem with unformatted file which come from HP-UX

["jean-david delemer" <jean-david dot delemer at wanadoo dot fr>]

Hello,

I've got a problem with unformatted files :

  I'd like to read unformatted files with g77(release 0.5.21) on linux redhat5.2)

  which are written with F77 on HP-UX(release 10.x).

On HP-UX :

       program examplewrite

         integer M,N

         parameter (M=10,N=10)

         real TAB1(M,N),TAB2(M,N)

         integer i,j

         do 1 j=1,N

         do 1 i=1,M

           TAB1(i,j)=1.0E0

           TAB2(i,j)=2.0E0

1       continue

         write(3) TAB1,TAB2

       end

I'd got a file ftn03 which I'd transfered with ftp and renamed fort.3 on linux

 

On linux :

       program exampleread

          integer M,N

         parameter (M=10,N=10)

         real TAB1(M,N),TAB2(M,N)

         read(3) TAB1,TAB2

       end 

      

I'd got the following message:

  do_us: off end of record

  apparent state : unit 3 named fort.3

  lately reading sequential unformatted external IO

  Aborted (core dumped)

 

It seems that the HP-station is a IEEE machine which means that :

  - numerical values are big endian;

  - unformatted files are sequential access by default.

Is PC-linux a IEEE machine ?

 

I've seen on the egcs web page that there is a new g77 release.

Can it avoid my problem?

 

Thanks for your answers
