myself. It was because my code file is mod_mymodule.cpp. I changed it to
mod_mymodule.c and the module loaded file. So I take it as FS accepts only C

<p class=MsoNormal>Hi, excuse me if this is already asked where else but I did
browse through the mailing list and I couldn’t find anything related. I tried
to create a new end point module by copying the mod_skel to mod/endpoints/my_module
folder. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I modified “skel” to my module name and basically I leave no
codes in the load function, just a few lines to test if the new module is
working. These few lines are:<o:p></o:p></p>

<p class=MsoNormal>It compiles but the module can’t load properly. I received

<p class=MsoNormal>Would someone tell me what do I miss here. <o:p></o:p></p>

<p class=MsoNormal>The same line of code couldn’t compile in my module coz VS
complains: cannot convert from void* to switch_endpoint_interface_t*. I know
C++ require more type-safe conversion than C but anyone got the same error?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>And how would I search in the mailing list ? Sorry for this
dumb question but I can’t seem to find out how to search in the archives. For
now, before posting anything, I need to try to browse through all the postings
first, which is <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>quite tedious to do.<o:p></o:p></p>
