error while using SPI files - development-with-gcc-and-eclipse

Hi, I followed steps specified for development-with-gcc-and-eclipse using link devzone.nordicsemi.com/.../

Following are the snapshots of my development environment which shows that headers(include path) are correct but still we can see errors in the console window.

"Application" is my virtual folder. spi0.c and spi0.h are my custom files. In spi0.c I have written following code

#if (SPI0_ENABLED == 1)
  const nrf_drv_spi_t m_spi_master = NRF_DRV_SPI_INSTANCE(0);
#elif (SPI1_ENABLED == 1)
  const nrf_drv_spi_t m_spi_master = NRF_DRV_SPI_INSTANCE(1);
#elif (SPI2_ENABLED == 1)
  const nrf_drv_spi_t m_spi_master = NRF_DRV_SPI_INSTANCE(2);
#else
  #error "No SPI enabled."
#endif

at line #error "No SPI enabled." I am getting #error encountered with text: "No SPI enabled." in eclipse while in console I get spi_master/nrf_drv_spi.c:45:6: error: #error "Wrong configuration."
