Hello *,

I have a dll (libSQL_nosql.dll), that gets loaded in run-time, with dlopen(). I cannot link this one.

This DLL uses some functions in another DLL (-laclshared = libaclshared.dll), that is always linked with client program
(.exe) via it's export library (libaclshared.dll.a), and with first dll (libSQL_nosql.dll), because it uses functions
from it. This one (-laclshared) links ok, using same make rules.

My first problem is that when I try to link libSQL_nosql.dll, I get undefined reference to `libaclshared_dll_a_iname',
but have no idea who or where is supposed to define it.

My second problem is undefined reference to `_nm__status'; as you can see below, __imp__status is auto-imported. What
the hack is `_nm__status' doing then?

Output:

dllwrap --driver-name gcc --def libSQL_nosql.def -o libSQL_nosql.dll nosql.o -L.
./.. -laclshared
Warning: resolving _status by linking to __imp__status (auto-import)

nmth000003.o(.idata$4+0x0): undefined reference to `_nm__sqlca'
collect2: ld returned 1 exit status
dllwrap: gcc exited with status 1

I did a RTFM and tried searching for _a_iname without success.

Your help is very much appreciated,
