Problem with Makefile

Question

Hi,

Using the command "make apps", I wanna generate two executables: main_test.exe and main_app2.exe. For some reason, the command to generate main_test.exe is more is less completley ignored when I run the makefile. Finally, I end up with a main_app.exe and main_app2.exe file but there is no main_test.exe file produced. Anyone an idea why objcopy command is ignored in my makefile?

# make apps to generate executables

main_app.exe: main.c lib3tests.a
 $(XCC) $(XCFLAGS) main.c $(XLDFLAGS) -o main_app.exe

main_test.exe: main_app.exe
  $/bin/sparc-elf-objcopy --add-section .myelfsection=file.txt --change-section-address .myelfsection=0xcd000000 --set-section-flags .myelfsection=alloc,contents,load,data main_app.exe

main_app2.exe: main.c lib3tests.a
 $(XCC) $(XCFLAGS) main.c $(XLDFLAGS) -o main_app2.exe

apps: main_app2.exe main_test.exe

Many thanks

Make sure you have a TAB character (not spaces) before sparc-elf-objcopy in this line:

main_test.exe: main_app.exe
    $/bin/sparc-elf-objcopy --add-section .myelfsection=file.txt --change-section-address .myelfsection=0xcd000000 --set-section-flags .myelfsection=alloc,contents,load,data main_app.exe

Your sparc-elf-objcopy command seems to lack an output filename.

Have you tried reducing your makefile to triviality, with no inline variables or other expansions occurring? I.e. Reduce it until make only calls your one line.

apps: main_app.exe
        sparc-elf-objcopy ... main_app.exe main_test.exe
