 TO WHOM IT MAY CONCERN
 ----------------------

sorry guys, 

 I need to program in FORTRAN 77.

Now, I switch from DIGITAL workstations to PC with Linux, 
and I use g77-3.2.2 as compiler. 

 I have the following BIG problem. 

Apparently I can not run a single jobs which occupies 
more RAM memory than 892 Mb 
(while my PC has ~2 Gb of ram, well seen by my 
mandreake-enterprise 9.1). 

The intel f90 (ifc) does not have this problem. 

 Are you aware of this problem of the g77 compiler. 
Any suggestion ?

 Thank you very much in advance for any helpful suggestion

If you want to run > 1 Gbyte programs on a 32-bit GNU/Linux machine, you 
have to link it statically, i.e., use:

g77 -static ....

to link the final executable.

The reason is that the shared libraries are mapped from address 2^30 
onwards.

Hope this helps,
