Issues in Porting RVCT library to gcc toolchain(arm-none-gnueabi-gcc)

Note: This was originally posted on 18th May 2010 at http://forums.arm.com

Hi,
I am currently porting RVCT generated static library into arm gcc toolchain(arm-none-gnueabi-gcc). I am currently getting the following errors.

1. Undefined reference to all Math Functions(sin,cos,pow,exp etc), I have included math.h header file & also the path to libm.so.6 but still I am getting undefined reference error.

2. Undefined reference to __aeabi_memmove4 __aeabi_memcpy4 __aeabi_memclr4.

Can anyone help me in getting out of this problem?

This might be useful:

I think the section on "helper libraries" is the one you are after.

Hi all,
I have now included an option --no_hide_all(to expose all symbols in library)option while builing rvct library,and all the undefined error to Math function have gone away, but still i am getting this error.

Undefined reference to __aeabi_memclr4.

Can anyone have any suggestion?

Hi,
I solved that problem too, there is an compiler option -Ono_memcpy which prevent arm compiler from optimizing memory related function .

So now I was able to integrate rvct generated library to arm-gcc toolchain

Thanks,
Santhosh

HI

I am also trying to port RVCT2.2 static library to gcc tool chain.
I have added the compiler option -Ono_memcpy & --no_hide_all.

All undefined memcpy & strlen errors have gone.
But I am still getting one error: unresolvable R_ARM_PLT32 relocation against symbol `memcpy@@VERS_1.17'

Does anyone know the reason for it?

Thanks
Shashanka
