Having Trouble Building SPI Test Program

QNX DEVELOPERS Realtime and Embedded

Hello,

I am trying to port MPC8349 SPI driver to MPC8360E. I have created the SPI test application. The thing is the build complained about anything to do with spi_xyz, e.g. “undefined reference to `spi_open(char const*), spi_read, spi_close, spi_xchange, …”

I have included the spi header to the c file:

#include <…/…/BSP/prebuilt/usr/include/hw/spi-master.h>

I think I need to link with a static library. But where can I get the SPI library?

Thanks,

This may sound like simple, but it does not build in my environment. My SPI test program does the following:

main()
{
spi_open()
spi_xchange()
spi_close()
}

I am using QNX 6.41:

  1. To be sure, I specifically copied the PowerPC libspi-master.a and libspi-masterS.a to both of C:/QNX641/target/qnx6/ppcbe/ and C:/QNX641/target/qnx6/ppcbe/usr/lib directories, which are supposed to the default directories.

  2. I then specified extra libraries llibspi-master.a under Properties/QNX C/C++ Project/Linker tab.

The build failed.

ntoppc-ld: cannot find -lllibspi-master.a

What could be wrong? I have attached the detailed build log below.

Thanks,
Jew-Dong

The problem is resolved. This is due to name mangling in C++. The library is done in C.
