Compiler/AM5726: CL6x compilation error

mustafa.gonul said:

I was trying to compile the example source on our side with cl6x compiler included within SDK6 for Linux.

Are you building from a command line or makefile or CCS? Could you show a screenshot of the entire compile command and output seen in whichever method you are using to build?

What are the options passed to the compiler? Try adding the --verbose option to the compiler, that should print out more detailed progress information. 

Hi,

Thanks for your patience, I could not respond in a short notice. 

I divide and conquer by commenting the code (it is a huge file) to find where is the problem. The problem is I could not write and build variadic functions. I have also created example project derived from printf_debug which included in the SDK examples. 

variadic_main.cpp

#include <cstdio>

extern "C" {
    extern int add_nums(int count, ...);
}

int main(int argc, char *argv[])
{
    int total = add_nums(4, 1, 2, 3, 4);

    printf("total: %d\n", total);

    return 0;
}

variadic_target.c

#pragma omp declare target
#include <omp.h>
#include <stdarg.h>
#pragma omp end declare target

int add_nums(int count, ...)
{
    int result = 0;
    int i = 0;

    va_list args;
    va_start(args, count);

    for (i = 0; i < count; ++i) {
        result += va_arg(args, int);
    }
    va_end(args);

    return result;
}

I am building the example with Makefile not CCS. For this example I simply use the same Makefile used for printf_debug.

include ../make.inc

OA_TC_OPTS 			= -O3
ifeq ($(VERBOSE),1)
OA_HC_OPTS 			= -O3 -Wall -Wextra -fopenmp
OA_SHELL_OPTS 		= -v -k --hc="$(OA_HC_OPTS)" --tc="$(OA_TC_OPTS)"
else
OA_HC_OPTS 			= -O3 -fopenmp
OA_SHELL_OPTS 		= --hc="$(OA_HC_OPTS)" --tc="$(OA_TC_OPTS)"
endif
CXX_OPTS 			= -O3

EXE     	= variadic
HOST_CODE 	= variadic_main.cpp
TARGET_CODE = variadic_target.c
OBJS 		= $(patsubst %.cpp,%.o,$(HOST_CODE))

$(EXE): $(OBJS)
	$(OA_SHELL) $(OA_SHELL_OPTS) $(OBJS) $(TARGET_CODE) -o $@

%.o: %.cpp
	$(CXX) $(CXX_OPTS) -c $<

clean:
	@rm -f $(EXE) $(OA_SHELL_TMP_FILES) *.log

You can see the output below:

I appreciate if you can help me regarding the issue.

Hi,

I would like to ask if there will be a new SDK release or patch release? I am not familiar with the procedure.

I appreciate if you can give further information regarding the procedure.

Kind regards,

Mustafa

Use the Alert Me feature on the AM57x Processor SDK download page.

Thanks and regards,
