Build error while building runtime library.

The Cortex-M0 device only supports Thumb2 instructions.  It does not support 32-bit ARM instructions.  I'm sure that is the root cause as to why your library build failed.

It is likely the tools could have failed more gracefully than they did.  Please capture the invocation of mklib and all of its output in a text file, and attach that file to your next post.

Thanks and regards,

I want to perform arithmetic operation on variables of 'double' data type specially the multiplication and division operation. Currently if double variable is used in multiplication result is coming zero or infinite. If i do the same operation with float variable it is working fine. But as in my software very large/very small values are involved so i have to use variable of double data type. I thought that the as library is build with 16bit version of multiplication code so my calculation results are zero. So i wanted to try with 32 bit version.

I have also attached the error which is received while building the runtime library.

Regards,

Abhimanyu

Please find attachment of snapshot of CCS6 for multiplication of long value and storing it in double value.

'HoldCJTValue' is of type long and 'CJT' is array of type double. 

value of 'HoldCJTValue'  is 53 for this , CJT[0] value shall be 2809, which is there,

CJT[1] shall be 7890481 but is infinity, CJT[2] shall be 62259690411361 but it is again infinity.

Below is the snapshot of memory browser and content of array is 

00000000 40A5F200 00000000 7FF00000 00000000 7FF00000

We thought it was an error in how CCS displayed the double values.  That is not the case.

I cannot reproduce your results.  If you can, please package up your project and attach it to your next post.  If that is not possible, then preprocess pga900_app.c and attach that.  We also need to know the version of the compiler (not CCS) and the exact build options used.

Thanks and regards,

-George

Please find attachment of project. It contains pga900_main.c, where the calculation is performed.

snapshot of arrays is also attached, from the snapshot it is very clear that only with float values calculation is yielding correct result.

Compiler version used is TI_v_5.2.4.code.7z

I don't know precisely what is going on, but it seems to have to do with little-endian.  I get a bogus "+Inf" result for the following test case:

/* armcl -Ooff -mv6m0 -me test.c */
#include <stdio.h>

double a = 4;
double b = 5;

int main()
{
    printf("%f\n", a * b);
}

By the way, you seem to be linking against the 5.1.1 compiler RTS; you should always link against the exact version of the RTS that matches the linker. I don't think this is the source of today's problem, but it could become a problem in the future.

[ This is now SDSCM00052216 -- Archaeologist ]

I tried to build the RTS as per the procedure mentioned on the link 

but I am getting the error as mentioned earlier.

Could you please build the rtsv6M0_T_le_eabi.lib for this version of compiler and share it.

Abhimanyu Kumar said:

I presume you mean the error where object files are missing.  Do you have write permission in the directory where the compiler libraries reside?  If that is not the error you see, please post exactly how you invoke mklib and the full system response.

I resist this request because this solution does not scale.  While it may come to that, I prefer to first spend more effort on finding the root cause of this build failure.

Thanks and regards,

-George

I tried to follow the same steps of building the library but it failed. So I copied all the executable in one lib/src folder and built, what i observed that object files are generated but it fails to combine the object files to make library.

Requesting  you to please share the video for building the library on windows machine with CCS6., compiler version 5.2.5

It will be really helpful for me to correct mistake if any.

Thanks,

Abhi

Our best information on building custom libraries is in the mklib wiki article you already know about.  I don't know what could be wrong.  This thread has been going on for quite a while.  While I still want to know the root cause of this problem, it is past time to get you a working library.  It is attached below, in .zip form.

Thanks and regards,

-George

rtsv6M0_T_le_eabi.zip

Thanks for sharing the runtime library.

Now I am able to build the runtime library. Earlier compiler_bin_dir path was not getting set so the build was failing.

Now to build the library i am using command

mklib --pattern=rtsv6M0_T_le_eabi.lib --compiler_bin_dir=D:\ti\ccsv6\tools\compiler\ti-cgt-arm_5.2.5\bin

earlier i was just using command

mklib --pattern=rtsv6M0_T_le_eabi.lib.

But, still the operation on 'double' variable is not working properly.

I have to use function 'double atan(double x)' , it takes double value and return double. but when i am using it i am getting infinity as output.

if i use 'flaot atanf(float x) i am getting proper value. This is happening with the new library shared by you as well as built by me.

Below is the code:

for float

float a;

a=atanf(1.0) * (float)(180/3.14159265);

the value of a will be 45.0 which is desired value.

but when i use double variant

double a;

a=atan(1.0) * (double)(180/3.14159265);

i am getting infinitty as output.

Thanks,

Abhimanyu

This problem was recorded earlier in this thread.  The SDOWP tracking ID is SDSCM00052216 .  Feel free to look it up with the SDOWP link below in my signature.  Note the recommended workaround.  Please see if that works for you.

Thanks and regards,
