Clarification

I want to create static library from my code to share the artifacts (but not the code). I will call this Main_Project.

In my Main_Project, I have startup.s and flash.ld files.

startup.s:

    .section    .isr_vector,"a",%progbits
    .type   g_pfnVectors, %object


g_pfnVectors:

    .word   HardFault_Handler
    .word   MemManage_Handler
    .word   BusFault_Handler
    .word   UsageFault_Handler'

flash.ld:

ENTRY(Reset_Handler)

I created static library named "Main_Lib.a" using all source and header files in my Main_Project.

After this point, I created an empty project is named "static_test". In this project, I added "Main_Lib.a", include files etc. After that, added static library to makefile as below but static_test can not find vector table from Main_Lib.a because I do not know how to implement that in empty project from a static library.

Makefile:

static_test.elf static_test.map: $(OBJS) $(USER_OBJS) makefile objects.list $(OPTIONAL_TOOL_DEPS)
    arm-none-eabi-gcc -o "static_test.elf" @"objects.list" $(USER_OBJS) $(LIBS) -mcpu=cortex-m4 --specs=nosys.specs -Wl,-Map="static_test.map" -Wl,--gc-sections -static -L"D:\workspace_arge\static_test\Lib" -l:Main_Lib.a -l:STL_Lib.a --specs=nano.specs -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb -Wl,--start-group -lc -lm -Wl,--end-group
    @echo 'Finished building target: $@'
    @echo ' '

Console Error:

D:/workspace_arge/static_lib_creator/Debug/../Src/tx_initialize_low_level.S:548: undefined reference to `g_pfnVectors'

How can I show or add my startup.s, tx_initialize_low_level.S and flash.ld configurations to static_test project?

• c
• gcc
• makefile
• static-libraries

• Edit your question with a minimal reproducible example. We have no idea where HAL_TIM_MspPostInit and g_pfnVectors are with the information you've currently provided. – Stephen Newell Commented Feb 6 at 12:27

You can't, because an archive with the contents you describe is not a "static library" in the relevant sense.

Although you can store arbitrary files in an ar-style archive, these days that is unconventional. If you want to create a distribution package for files other than object files then it would be better to use a tar archive, possibly compressed, or maybe a ZIP archive.

Moreover, the recipient of any of these, even the ar archive, will almost certainly need to extract the files from the archive in order to use them. Build tools do not, in general, accept sources, linker scripts, or similar such files packaged in archives.

With regard to this ...

undefined reference to `g_pfnVectors'

Your startup.s is a source file, written in assembly language. I guess its name has special significance to certain IDEs. It needs to be assembled to produce an object file, and the result linked into your program. The linker cannot consume it directly, regardless of how it is packaged.

How can I show or add my startup.s, tx_initialize_low_level.S and flash.ld configurations to static_test project?

Unpack them from your archive into appropriate locations in your project's source space. If you are using an IDE (you didn't say, much less specify a particular one) then that may affect the details of which are the appropriate locations, and there may be additional, IDE-specific steps for configuring the project. Otherwise, details are driven by your makefile, build script, or intended sequence of manual build commands.
