TMS320C6678: 一个关于omp_config.cfg文件的报错问题

xing zihan

Part Number: TMS320C6678
Other Parts Discussed in Thread: FFTLIB

如下图所示，编译fft_omp_sp_1d_c2c_k1_66_LE_ELF例程时总是出现报错，怀疑是不是例程自带的omp_config.cfg文件本身编写就有问题

使用的环境是CCS5.5，例程是FFTLIB库：fftlib_c66x_2_0_0_2，里面的fft_omp_sp_1d_c2c_k1_66_LE_ELF

错误：Cannot read property "base" from undefined (D:/ti/workspace_v5/fft_omp_sp_1d_c2c_k1_66_LE_ELF/omp_config.cfg#97)

OpenMP.msmcBase = msmc.base;
OpenMP.msmcSize = msmc.len;
//编译显示在这一行出现错误
OpenMP.msmcNoCacheVirtualBase  = msmcNcVirt.base;
OpenMP.msmcNoCacheVirtualSize  = msmcNcVirt.len;

OpenMP.msmcNoCachePhysicalBase  = msmcNcPhy.base;

OpenMP.ddrBase          = ddr3.base;
OpenMP.ddrSize          = ddr3.len;

您好，

可以看下工程师的答复：

目前应该没有方法可以通过 CCS 构建 fftlib 的选项。

根据以下文档，GNU make 生成过程位于"/ti/fftlib_3_1_0_0/docs/doxygen/html/gnu_build.html "

FFTLIB Build Procedure

The FFTLIB may be compiled using GNU make following the procedure below. Note that the first three items are followed by two options, either of which may be used to accomplish the goal.

Add cygwin/bin to the environment PATH (Windows only)
Correct the *_INSTALL_DIR path in the makefile (two options)
- Directly modify the makefile OR
- Set the *_INSTALL_DIR in the environment with the proper tools path
Correct the FFTLIB_INSTALL_DIR path in the makefile (two options)
- Directly modify the makefile OR
- Set the FFTLIB_INSTALL_DIR in the enviornment to the packages folder e.g. FFTLIB_INSTALL_DIR := /opt/ti/fftlib_k2hx_2_0_0_4/packages
Build the library
- Enter make all to build the library
- Enter make clean to clean all generated object files and artifacts
