我正在尝试运行SAM（SPARC架构建模工具），在编译之后，当我使用“run_sam.sh”脚本时，它调用python接口并发出错误：
starting py interface...
UI: start py thread, tid = 5
stop: Traceback (most recent call last):
File "lib/frontend/sam_n1.py", line 26, in ?
import riesling_n1
File "/scratch/sam-t1/lib/frontend/riesling_n1.py", line 4, in ?
import _riesling_n1
ImportError: dynamic module does not define init function (init_riesling_n1)

我对此非常陌生，如果不能正确提问，请提前道歉。请帮忙。
我看到以下文件：“riesling_n1.i”，“riesling_n1_wrap.cc”和“riesling_n1.py”。我认为最后一个是运行Makefile.swig后创建的python文件。

我在Makefile中找到了以下几行代码和其他代码：
@/bin/cp -fp ../$(LIB_PATH)/riesling_n1.py $(INSTALL)/frontend/.
@/bin/cp -fp ../$(LIB_PATH)/libriesling_n1_vcpu.so $(INSTALL)/.
@/bin/cp -fp ../$(LIB_PATH)/libriesling_n1_vcpu.so $(INSTALL)/libSUNW,UltraSPARC-T1.so
@/bin/cp -fp ../$(LIB_PATH)/_riesling_n1.so $(INSTALL)/.
而且，一旦我编译swig并因此得到原始错误，_riesling_n1.so就会被破坏。当我用原始的（与包附带的那个）替换_riesling_n1.so时，SAM工作。这意味着在编译期间它会以某种方式弄乱共享对象库文件。
请告知（如果可能的话）找出造成这种情况的原因。
答案 0 :(得分：1)
根据SWIG 2.0文档：
当给共享对象文件指定错误名称时，几乎总是会导致此错误。例如，如果您创建了一个文件example.so而不是_example.so，则会出现此错误。或者，如果模块的名称与％module指令提供的模块名称不一致，则可能会出现此错误。仔细检查接口以确保模块名称和共享对象文件名匹配。导致此错误的另一个可能原因是在创建扩展模块时忘记将SWIG生成的包装器代码与应用程序的其余部分链接。
因此检查_riesling_n1.so是否存在且可由动态加载程序找到（即它位于启动py接口的文件夹中或LD_LIBRARY_PATH中）。我没有在你发布的代码中看到任何.so make规则，所以也许.so甚至没有构建（.py文件的存在与此不矛盾;该文件由SWIG创建）。同时确保%module中的riesling_n1.i为riesling_n1。
