How do I link linker file from static library?

[B.Kaya]

 

I am trying to link static library in gcc. Getting error "Undefined reference to 'g_pfnVectors'" and "Undefined reference to 'HAL_TIM_MspPostInıt'"

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/App_HW_655H1X.c:3482: undefined reference to `HAL_TIM_MspPostInit'
D:/workspace_arge/static_lib_creator/Debug/../Src/tx_initialize_low_level.S:548: undefined reference to `g_pfnVectors'

I guess that I have a problem about adding linker file.

Merged from separate thread.

 

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 _estack
 .word Reset_Handler
 .word NMI_Handler
 .word HardFault_Handler
 .word MemManage_Handler
 .word BusFault_Handler
 .word UsageFault_Handler'

flash.ld:

/* Entry Point */
ENTRY(Reset_Handler)

/* Highest address of the user mode stack */
_estack = ORIGIN(RAM) + LENGTH(RAM); /* end of "RAM" Ram type memory */

_Min_Heap_Size = 0x200; /* required amount of heap */
_Min_Stack_Size = 0x400; /* required amount of stack */

/* Memories definition */
MEMORY
{
 RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
 FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 436K
 API (rx) : ORIGIN = 0x806D000, LENGTH = 32K
}

/* Sections */
SECTIONS
{
 /* The startup code into "FLASH" Rom type memory */
 .isr_vector :
 {
 . = ALIGN(4);
 KEEP(*(.isr_vector)) /* Startup code */
 . = ALIGN(4);
 } >FLASH

 /* The program code and other data into "FLASH" Rom type memory */
 .text :
 {
 . = ALIGN(4);
 *(.text) /* .text sections (code) */
 *(.text*) /* .text* sections (code) */
 *(.glue_7) /* glue arm to thumb code */
 *(.glue_7t) /* glue thumb to arm code */
 *(.eh_frame)

 KEEP (*(.init))
 KEEP (*(.fini))

 . = ALIGN(4);
 _etext = .; /* define a global symbols at end of code */
 } >FLASH
 
 .api_section :
 {
 . = ALIGN(4);
 __api_section_start__ = .;
 *(.api_section*)
 __api_section_end__ = .;
 } > API
 
 ASSERT(LENGTH(API) >= (__api_section_end__ - __api_section_start__), "API memory overflowed !")

tx_initialize_low_leve.S:

 .global _tx_thread_system_stack_ptr
 .global _tx_initialize_unused_memory
 .global _tx_timer_interrupt
 .global __main
 .global __tx_SVCallHandler
 .global __tx_PendSVHandler
 .global __tx_NMIHandler @ NMI
 .global __tx_BadHandler @ HardFault
 .global __tx_SVCallHandler @ SVCall
 .global __tx_DBGHandler @ Monitor
 .global __tx_PendSVHandler @ PendSV
 .global __tx_SysTickHandler @ SysTick
 .global __tx_IntHandler @ Int 0
 .global __Vectors
#ifdef USE_DYNAMIC_MEMORY_ALLOCATION
 .global Image$$RW_IRAM1$$ZI$$Limit
#endif
@
@
SYSTEM_CLOCK = 160000000
SYSTICK_CYCLES = ((SYSTEM_CLOCK / 1000) -1)

 .text 32
 .align 4
 .syntax unified

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?
