problem with MyBackendId

[Andreas 'ads' Scherbaum]

Hello,

i successfully installed PostgreSQL 8.0.3 and MingW on a windows xp box
and tried to compile a module of mine. Thats the error i got back:

$ make
sed 's,MODULE_PATHNAME,$libdir/tablelog,g' tablelog.sql.in >tablelog.sql

c:\mingw\bin\dllwrap.exe: c:\mingw\bin\gcc exited with status 1

He seems to be able to resolv MyBackendId, but thats all.
Has anybody an idea what is missing or wrong?
Thanks in advance.


Kind regards

MyBackendId isn't DLLIMPORT'ed.  I believe you can hack around this by
doing

extern DLLIMPORT BackendId MyBackendId;

in your own code.
