Hi, Wim
I tried, but when I use the automatic class loader, the problem still exists.
HERE is the error.
1.
$ echo $LD_LIBRARY_PATH
/home/GeV/work/hello/v1/src:/opt/root/lib/root
$ ls /home/GeV/work/hello/v1/src
libMyClassDict.rootmap libMyClassDict.so MyClass.h MyClass_rflx.cpp
>>>> import cppyy
>>>> myinst = cppyy.gbl.MyClass(42)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: <class '__main__.::'> object has no attribute
'MyClass' (details: '<class '__main__.::'>' has no attribute
'MyClass')
2. TRY explicit load statements, Just as that Armin told me, It's OK,
works perfectly
$ echo $LD_LIBRARY_PATH
/opt/root/lib/root
>>>> import cppyy
>>>> cppyy.load_reflection_info("./libMyClassDict.so")
>>>> myinst = cppyy.gbl.MyClass(42)
42
3. Use LD_LIBRARY_PATH to clarify the path to libMyClassDict.so, still error
$ echo $LD_LIBRARY_PATH
/home/GeV/work/hello/v1/src:/opt/root/lib/root
>>>> import cppyy
>>>> cppyy.load_reflection_info("libMyClassDict.so")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: libMyClassDict.so: cannot open shared object file: No
such file or directory
I don't understand why the LD_LIBRARY_PATH did not work well on my PC.
Waiting for your reply. Thanks!
Best wishes,
Xia Xin
