Compiling and Distributing Via an RPM

The makefiles for the application are covered first, followed by the RPM spec file. The makefiles for the KBI and tabular executables are given in Listings Listing 13.1 and Listing 13.2; the other makefiles (those for the pie chart, the bar/line chart, and the scatter plot chart) are the same as that in Listing 13.2, except that the name of the executable is different for each one.

The Makefiles

Listing 13.1 is the makefile for the KBI executable. It is the controlling application that calls the other executables, which is why it has a slightly more complicated install section than those in Listings 13.2 and 13.3.

Listing 13.1 Makefile for the KBI Executable

  # Makefile for the KBI Application.   # Chapters 11, 12, and 13. */  CC = gcc -Wall  MYSQL-INCLUDES = -I/usr/include/mysql  MYSQL-LIBS = -L/usr/include/mysql -L/usr/lib/mysql -lmysqlclient -lz  GTK-CONFIG = `gtk-config --cflags --libs`  GTK-INCLUDES = `gtk-config --cflags`  GTK-LINKS = `gtk-config --libs`  kbi : main.o interface.o support.o callbacks.o kbi_utils.o        $(CC) -o kbi *.o $(GTK-CONFIG) $(MYSQL-INCLUDES) $(MYSQL-LIBS)        cp -f kbi /usr/local/bin/kbi  main.o : main.c        $(CC) -c main.c $(GTK-INCLUDES)  interface.o : interface.c        $(CC) -c interface.c $(GTK-INCLUDES)  support.o : support.c        $(CC) -c support.c $(GTK-INCLUDES)  callbacks.o : callbacks.c        $(CC) -c callbacks.c $(GTK-INCLUDES)  kbi_utils.o : kbi_utils.c        $(CC) -c kbi_utils.c $(GTK-INCLUDES) $(MYSQL-INCLUDES)  # Note that you can force a full rebuild by calling   #  make clean  before calling  make  or  make install  .

Listings 13.2 and 13.3 are the makefiles for the tabular and pie executables, respectively.The fundamental difference between them is that the makefile for tabular (Listing 13.2) includes ddc.c , whereas the pie program make fi le compiles piechart_utils.c .

Listing 13.2 Makefile for the Tabular Executable

  # Makefile for the KBI Application.   # Chapters 11, 12, and 13. */  CC = gcc -Wall  MYSQL-INCLUDES = -I/usr/include/mysql  MYSQL-LIBS = -L/usr/include/mysql -L/usr/lib/mysql -lmysqlclient -lz  GTK-CONFIG = `gtk-config --cflags --libs`  GTK-INCLUDES = `gtk-config --cflags`  GTK-LINKS = `gtk-config --libs`  tabular : main.o interface.o support.o callbacks.o ddc.o        $(CC) -o tabular *.o $(GTK-CONFIG) $(MYSQL-INCLUDES) $(MYSQL-LIBS)        cp -f tabular /usr/local/bin/tabular  main.o : main.c        $(CC) -c main.c $(GTK-INCLUDES)  interface.o : interface.c        $(CC) -c interface.c $(GTK-INCLUDES)  support.o : support.c        $(CC) -c support.c $(GTK-INCLUDES)  callbacks.o : callbacks.c        $(CC) -c callbacks.c $(GTK-INCLUDES) $(MYSQL-INCLUDES)  ddc.o : ddc.c        $(CC) -c ddc.c $(GTK-INCLUDES) $(MYSQL-INCLUDES)  clean::        rm -f *.o  EXE_LOCATION = /usr/local/bin/  # In the commands below   #     The  -f  after  cp  tells  cp  to overwrite an existing file of   #            the same name in the target location if such a file   #            already exists. */  install : tabular        cp -f tabular $(EXE_LOCATION)tabular        chmod 755 $(EXE_LOCATION)tabular        echo Tabular Graph Installed. 

Listing 13.3 is the makefile for the pie chart executable. It is the same basic structure as the tabular and KBI makefiles in Listings 13.1 and 13.2. The makefiles for bar_line and scatter will be the same as Listing 13.3, except the name of the executable will be different, of course.

Listing 13.3 Makefile for the Pie Program

  # Makefile for the KBI Application.   # Chapters 11, 12, and 13. */  CC = gcc -Wall  MYSQL-INCLUDES = -I/usr/include/mysql  MYSQL-LIBS = -L/usr/include/mysql -L/usr/lib/mysql -lmysqlclient -lz  GTK-CONFIG = `gtk-config --cflags --libs`  GTK-INCLUDES = `gtk-config --cflags`  GTK-LINKS = `gtk-config --libs`  pie : main.o interface.o support.o callbacks.o piechart_utils.o        $(CC) -o pie *.o $(GTK-CONFIG) $(MYSQL-INCLUDES) $(MYSQL-LIBS)  cp -f pie /usr/local/bin/pie  main.o : main.c        $(CC) -c main.c $(GTK-INCLUDES)  interface.o : interface.c        $(CC) -c interface.c $(GTK-INCLUDES)  support.o : support.c        $(CC) -c support.c $(GTK-INCLUDES)  callbacks.o : callbacks.c        $(CC) -c callbacks.c $(GTK-INCLUDES)  piechart_utils.o : piechart_utils.c        $(CC) -c piechart_utils.c $(GTK-INCLUDES) $(MYSQL-INCLUDES)  clean::        rm -f *.o  EXE_LOCATION = /usr/local/bin/  #  In the commands below   #     The  -f  after  cp  tells  cp  to overwrite an existing file of   #            the same name in the target location if such a file   #            already exists.  install : pie        cp -f pie $(EXE_LOCATION)pie        chmod 755 $(EXE_LOCATION)pie        echo Pie Chart Installed. 

The RPM Spec File

Listing 13.4 is the kbi.spec file used to create the RPM. This spec file differs in several fundamental ways from that of the Worldwide Commissions Application in Chapter 9, Constructing the Commissions Application, and Chapter 10, Commission Calculations Deployment.

The Preamble, description, and prep sections are essentially the same. The build section is empty, however, because each of the executables is built separately using its own makefile . The install section consists of copying the executables to /usr/local/bin where the KBI executable can find them. The %files section includes the files from the development machine s /usr/local/bin directory; the makefiles copy them to that location as part of the make process to ensure that /usr/local/bin always contains the latest executables.

Listing 13.4 kbi.spec: The RPM Spec File for the KBI ( group of) Applications

Figure 13.1 shows the KBI application installed using the RPM. The appropriate menu choice has been added to the GNOME menu, and the GNOMERPM displays the installed package.

Figure 13.1. The KBI group of applications is installed. The menu bar shows the In House Application start menu, the file manager shows the contents of /usr/local/bin, and the GNOMERPM window shows the installed package.

To build the RPM file, enter the following command:

 % rpm -bb kbi.spec 

The -bb switch tells RPM to build only the binary .rpm file, not the source .rpm file.
