Can keil compiled library be used in segger embedded studio?

[Liuguofeng]

dear all 

    Can keil compiled library be used in segger embedded studio? For example, I have a paw8001_ ofn114009_ 12_ m4f_ keil.lib

Library, can I put it directly into NRF connect SDK project to compile?

Best Regards

Hi,

No, that will not work, primarily because of different wchar size between Keil and GCC (which is used by SES).

Thank you very much for your reply. If I use GCC library, is that ok?

Hi,

Have you attempted to build with CONFIG_COMPILER_OPT="-lm"?

(In SES you add compiler options by clicking Extended Settings in the dialog  you get from Open nRF Connect SDK Project..., and then add it under Extra CMake Build Options)

hi 

I put the config_ COMPILER_ Opt = - LM "into my pri.conf, the problem still exists, But there's one amazing thing，When I put the following code in *. C,Even though I don't make any calls。The compilation is successful。

It looks like there's something wrong with the compiler。

#include <math.h>

#if(1)
int compare(const void *, const void *);
void test(void)
{
const char *a[10] = {"enter", "number", "size", "begin", "of", "cat", "case","program","certain","a"};
float op;
float result;
op = 0.08;
result= sqrtf(op);
result= log10f(op);
result= expf(op);
result= cosf(op);
qsort(a, 10, sizeof(a[0]), compare);
result= tanf(op);
result= sinf(op);
result= logf(op);
}

int compare(const void *c, const void *d)
{
int m,n,r;
char **a, **b; // !!
a = (char **)c;
b = (char **)d;
m = strlen(*a);
n = strlen(*b);
r = m - n;
if (r != 0)
return r; 
return memcmp(*a,*b,m); 
}
#endif

best regards

Hi,

It is good you have a work around, but it seems odd. I agree this seems like a compiler issue. I am not able to find any reference to this, but perhaps it is worth testing a different GCC version (though the workaround seems fair enough).

dear Einar Thorsrud

 By the way

 I encountered a strange problem with mcuboot in ncs1.6.0, and the program has been running for a long time  to FIH_PANIC  and It's not going to work.

  FIH_CALL(boot_go, fih_rc, &rsp);
  if (fih_not_eq(fih_rc, FIH_SUCCESS)) {
    BOOT_LOG_ERR("Unable to find bootable image");
    FIH_PANIC;
}

Please ask what causes this？

best regards

Hi,

Please open a new case for this question as it is not directly related to the original topic. (Also, I will be OoO from three weeks from today and unable to reply.)
