An overview of HP Fortran
Linker
Chapter 114
Linker
The linker (ld) builds an executable program from the object files produced by the back end
and the libraries. An important group of options for controlling the linker specify what
libraries the linker should search and where it should search for them. Other options control
the type of information that the linker should or should not include in its output file, such as
symbol table information used by the debugger or marks identifying the output file as
shareable or demand-loadable. Table 1-6 lists and briefly describes options that control the
linker.
NOTE If you use the f90 command to compile and link on separate command lines
and compile with any of the options (except -c) listed in Table 1-6, you must
specify the same options on the link line as well.
Table 1-6 Options for controlling the Linker
Option Function
-c Suppress linking; produce object files only.
+[no]demand_load Mark [do not mark] the output file from the linker demand load .
If you compile and link separately and specify +demand_load on
the command line, you must also specify it on the link line. The
default is +nodemand_load.
For information about using this option, see “Creating
demand-loadable executables” on page 92.
+FP flags Specify how the runtime environment for trapping floating-point
exceptions should be initialized at program startup. If you
compile and link separately and specify +FP on the command
line, you must also specify it on the link line with the identical
set of flags . The default is that all traps are disabled. See the
ld (1) man page for specific values for flags .
For information using this option, see “Floating-point exceptions”
on page 120.
