Trouble building with 32-bit doubles

I have a project in Crossworks 2.2 targeted at an STM32F103.  When I try to build with the "Treat 'double' as 'float'" option enabled I get the following errors:

  cannot find C:/Program Files/Rowley Associates Limited/CrossWorks for ARM 2.2/lib/libm_v7m_t_le_f.a: No such file or directory
  cannot find C:/Program Files/Rowley Associates Limited/CrossWorks for ARM 2.2/lib/libc_v7m_t_le_f.a: No such file or directory
  cannot find C:/Program Files/Rowley Associates Limited/CrossWorks for ARM 2.2/lib/libcpp_v7m_t_le_f.a: No such file or directory

  cannot find C:/Program Files/Rowley Associates Limited/CrossWorks for ARM 2.2/lib/libc_user_libc_v7m_t_le_f.a: No such file or directory

Any idea what's going on or how I can fix this?

 

Thanks,

Jay

  The release notes say "Library variants are now built for double as float (ARM EABI only)".

  Try setting the 'GCC Target' project property to 'arm-unknown-eabi'.
