Invocation
and
Operation
of
the
TMS34010
C
Compiler
Example
Description.
First, the desired linker options are listed:
-c
Option used
for
linking C programs,
as
described in the previous sec-
tion.
If
-c
is
not
used, its effects must be provided using other linker
directives.
-m
Option used
to
create a map file.
Follow
the
option
with
a string that
represents a valid file name.
-0
If
no errors occur
during
link
time, the linker creates an .out (executa-
ble) file. The default file name for this file
is
a.out.
If
you
wish
to
alter
this default file
name, use the
-0
option
followed
by a string repres-
enting a valid file name.
Next, all the object files
to
be linked
are
listed, in any order. One
of
these files
must define the symbol
main, because boot.obj calls main
as
the start
of
your
C program.
Note:
If
any
of
the files
are
in assembly language,
they
may
not
contain .data
sections because this
will
corrupt the C auto-initialization environment.
Any
included .obj files
are
linked into the resultant
.out
file, whether they are
used
or
not,
while
only
referenced files from libraries
are
linked in.
Finally, all the archive object libraries
that
are
to
be searched
are
listed. Only
modules from the libraries
that
resolve unresolved references
are
included in
the
output
file.
