Hi Gerrit,
I tried that, but I am still getting the following error.
$ gcc -shared -o
libbridge.dll -Wl,--out-implib=libbridge.dll.a -Wl,--export-al
l-symbols -Wl,--enable-auto-import -Wl,--whole-archive bridge.o nwutil.o
jagsoc
ket.o -Wl,--no-whole-archive
Creating library file: libbridge.dll.a
nwutil.o(.text+0x57):nwutil.c: undefined reference to `_h_nerr'
nwutil.o(.text+0x63):nwutil.c: undefined reference to `_h_errlist'
collect2: ld returned 1 exit status
Any idea what package is h_nerr and h_errlist are defined in?
Jag
