关于程序包含CSL库的问题

chao fan

我在编写6678程序的时候，由于要用到CSL_chipReadReg()这个函数，于是就在程序里包含了头文件#include <ti/csl/csl_chip.h>

程序build的时候说找不到csl_chip.h这个文件，然后我在工程build setting里的include search path里加入了csl_chip.h文件的路径（我的MCSDK是装在C盘底下的，CCS装在D盘底下），再次build的时候上一个错误消失了，但是又有了一个新的错误，说我的 CSL_chipReadReg()是undefined symbol。

 

这该怎么解决啊？我的工程是建立在G盘底下的。

    请在include searche path中包含相应的CSL lib库。

    Andy Yin  您好！

    我在C6000 Linker的File Search Path中添加了CSL lib库的地址（如下）但是依然不行。还是说 CSL_chipReadReg()是undefined symbol。

    C:\Program Files\Texas Instruments\pdk_C6678_1_0_0_9_beta2\packages\ti\csl\lib

    一般这种问题都是你的库和头文件路径不对，请仔细检查

    chao fan您好，

    请确认选择上述目录下的CSL lib文件，如ti.csl.ae66e，同时请留意编译链接时是否存在相应的CSL lib，如果还存在问题，请将编译时打印的东西贴上来，谢谢

    Andy Yin 您好，

    我把CSL lib库加入了，但是情况还是像原来一样，编译的提示是这样的：

    'Building target: matrix_transposition.out'

    'Invoking: C6000 Linker'

    "D:/Program Files/Texas Instruments/ccsv5/tools/compiler/c6000/bin/cl6x" -mv6600 -g -O2 --diag_warning=225 --abi=eabi -z -m"matrix_transposition.map"  --stack_size=400 --warn_sections -i"D:/Program Files/Texas Instruments/pdk_C6678_1_0_0_16/packages/ti/csl/lib" -i"D:/Program Files/Texas Instruments/ccsv5/tools/compiler/c6000/lib" -i"D:/Program Files/Texas Instruments/ccsv5/tools/compiler/c6000/include"  --reread_libs --rom_model -o "matrix_transposition.out"  "./matrix_trans.obj" -l"libc.a" "../matrix.cmd"

    CSL_chipReadReg ./matrix_trans.obj

    我试着把csl_chip.c这个文件复制一份到工程目录底下，结果编译通过了。但是我还是想找出不用复制源文件到工程目录下使用库函数的方法。谢谢帮助！

    您好，

    我在本机测试结果如下，请参考。

    在没有添加相应的CSL lib时，对应编译提示如下：

    'Invoking: C6000 Linker'

    在加入C:\Program Files\Texas Instruments\pdk_C6678_1_0_0_9_beta2\packages\ti\csl\lib\ti.csl.ae66之后，编译提示如下：
