[AXISCPP-328] Axis methods exported from user dlls

• Type: Bug
• Status: Open

Description

I am raising this JIRA based on a discussion on the mailing list (see below). This is a bug because the external header files that Axis C++ ships should not contain __declspec(dllexport) since that makes Axis methods exported from application dlls. In other words if a user creates an application that uses (and dynamically links to) Axis C++ and builds that application into a dll, Axis C++ methods will be exported from the application's dll, which may not be what the user wanted. The solution to this is to remove __declspec(dllexport) from the external header files and tell the compiler/linker to export Axis methods from the AxisClient.dll by some other internal mechanism.
Discussion from the mailing list follows....

I changed
#define STORAGE_CLASS_INFO __declspec(dllexport) in GDefine.hpp to
#define STORAGE_CLASS_INFO
now only my functions are exported as expected. Is this an acceptable
solution though?

Vince.

Hi,
Methods are exported from the AxisClient.dll by setting
__declspec(dllexport) on the class definition (look in Call.hpp and
GDefine.hpp). I guess you are creating your own dll which dynamically
links
to the AxisClient.dll. I'm surprised that the methods which are exported
from the AxisClient.dll are also exported from your dll. I don't know
the
answer but you could try

• making sure you are dynamically linking to the AxisClient.dll not
  statically linking to it
• see if there is another __declspec override that will "switch off"
  exporting a method
• remove the __declspec(dllexport) from the axis public header files
  that
  you include
  If this last suggestion works then it looks like a bug in Axis.

Subject: dll exports

Hi:

I'm trying to build a dll which calls my axis java webservice everything
has built ok and I'm able to call the webservice, the only thing is that
when I look at the dll it has other functions exported besides the one's
that I made. My question is how can I make the other functions not
exported.
