Hi,

I was able to use --float_support=none option when compiling my C code for ARM processor. Thanks for your good advice.

However, the compiled file(.lib) occurs following error when I try to build VisionSDK using the .lib file.

[An error like this: ] *** uses VFP register arguments, *** does not.

I expected this error can be resolved if I use --float_support=none option when compiling C source but not.

Could you give me adveise?

I will attach additional information below:

* Source code for testing
myprintf.h and myprintf.c (Attached to this thread.)
* Commands I entered
  ../bin/armcl --include_path ../include/ --little_endian --float_support=none myprintf.c
then,
  ../bin/armar -a myprintf myprintf.obj
and I got myprintf.lib (Attached to this thread).
* Compiler ver.
  ti-cgt-arm_18.1.5.LTS

Thanks,

Koji

myprintf.h

myprintf.c

#include "myprintf.h"

void myprintf(int x){
	printf("****my_printf_test****  %d \n", x);
}

myprintf.lib

Hi,

Can I know the reason why you are setting "--float_support=none" ?

Thanks

Hi Gaviraju,

Because avoiding this error.

[An error like this: ] *** uses VFP register arguments, *** does not.

Is "--float_support=none" wrong solution for this?

Thanks,

Koji

Can you try with --float_support=vfplib ?

I tried it, but the result does not change.

Hi,

In which core are you linking the library? IPU or A15

Thanks

Hi Gaviraju,

The target core is A15.

Thanks,

Koji

Hi,

The above compiler used for IPU cores in VSDK, So you should link .lib files to IPU core only

For A15 is using different compiler

Thanks

Gaviraju-san,

Which compiler should I use for A15?

Thanks,

Hi Gaviraju,

I succeeded to compile A15 source codes, build it on VSDK and execute it on EVM.

Thanks for your support.
