Hi all,
I'm reading the GNU Make book I cannot understand the following syntax from the book.
If I run:
, I get the output:
I think I understand that line $(objects) : %.o : %.c produces line cc -c foo.c when the target is foo.o. This is because $(objects) : %.o : %.c is converted into foo.o : foo.c right?
But I cannot see the process that produces the second line: cc -o foo foo.o.
I have this program which has lots of source files in the directories
src
src/dir1
src/dir2
src/dir3... and so on
I am trying to understand the following Makefile:
CC = gcc
CFLAGS= -g -c -D_REENTRANT
SOURCES = src/main.c src/dir1/a.c src/dir1/b.c src/dir2/x.c src/dir2/y.c ...and so on... (5 Replies)

cmds
.c.o:

Despite the positoning of the 2 rules, .c.o... (1 Reply)

I'm writing a program which uses curl to be run on Linux PCs which will be used by a number of different users.

DtMmdbBookGetTocObjectId(library call) DtMmdbBookGetTocObjectId(library call)
NAME
DtMmdbBookGetTocObjectId -- obtains the locator of a book's TOC section
SYNOPSIS
#include <DtMmdb.h>
DtMmdbHandle* DtMmdbBookGetTocObjectId(
DtMmdbInfoRequest* request);
DESCRIPTION
The DtMmdbBookGetTocObjectId function returns the object identifier of the specified book's TOC section. Use the DtMmdbFreeHandleList
function to release the memory when the object identifier is no longer needed. Table lookup is involved when the identifier is specified by
either the primary_oid or sequence_num field.
ARGUMENTS
request Specifies the bookcase in the bookcase descriptor field, as well as a valid value in the primary_oid, the secondary_oid, or the
sequence_num field. The primary_oid represents the DtInfo Database object identifier of the TOC section; the secondary_oid rep-
resents the object identifier of the book itself; and the sequence_num represents the sequence number of the book within the
bookcase (0 based). If more than one of these fields have a valid value, the order of precedence is: primary_oid, secondary_oid,
and, last, sequence_num.
RETURN VALUE
If DtMmdbBookGetTocObjectId completes successfully, it returns a pointer to the object identifier for the book's TOC section. If it fails,
it returns a NULL pointer.
EXAMPLE
The following shows how a DtMmdbBookGetTocObjectId call might be coded.
DtMmdbInfoRequest request;
request.bookcase_descriptor = DtMmdbGetBookCase(myInfoLibPtr, "myBase");
request.sequence_num = 1;
DtMmdbBookGetTocObjectId(&request);
