Hi again,
Thanks very much for your help. I've been working on this some more,
and I think that the first solution is the better one. The follow is
executed, (excerpt from make's output) with the following errors too.
echo EXPORTS > qa.def
nm code_block.o qa.o qa_options.o | grep '^........ [T] _' | sed
's/[^_]*_//' | sort >> qa.def
ld --base-file qa.base -o qa.exe code_block.o qa.o qa_options.o
-L/opt/local/gnu/lib
ld: warning: cannot find entry symbol _mainCRTStartup; defaulting to 00401000
code_block.o(.text+0xa6):code_block.cc: undefined reference to
`std::basic_ostream....
I know that there's something that I'm overlooking (most likely really
basic and silly to miss), but after staring at all this compiler
output, I swear that my brain has been fried. :)
>From the Makefile, the full commands that I am attempting to use are:
# Export symbols
echo EXPORTS > $(COMMAND.qa).def
nm $(OBJECTS.qa) | grep '^........ [T] _' | sed 's/[^_]*_//' | sort
>> $(COMMAND.qa).def
# Link the DLL
ld --base-file $(COMMAND.qa).base -o $(COMMAND.qa).exe $(OBJECTS.qa)
-L/opt/local/gnu/lib $(EXTRALIBS) $(LDFLAGS)
dlltool --as=as --dllname $(COMMAND.qa).exe --def $(COMMAND.qa).def
--base-file $(COMMAND.qa).base --output-exp $(COMMAND.qa).exp
ld --base-file $(COMMAND.qa).base $(COMMAND.qa).exp -o
$(COMMAND.qa).exe $(OBJECTS.qa) $(BIG_LIBRARY) $(EXTRALIBS)
$(LDFLAGS)
dlltool --as=as --dllname $(COMMAND.qa).exe --def $(COMMAND.qa).def
--base-file $(COMMAND.qa).base --output-exp $(COMMAND.qa).exp
ld $(COMMAND.qa).exp -o $(COMMAND.qa).exe $(OBJECTS.qa)
$(BIG_LIBRARY) $(EXTRALIBS) $(LDFLAGS)
#Build the .a lib to link to
dlltool --as=as --dllname $(COMMAND.qa).exe --def $(COMMAND.qa).def
--output-lib lib$(COMMAND.qa).a
It's a real pity that the switch -Wl,--out-implib,[name].a doesn't
work. All the same, thanks a heap to all the Cygwin developers - even
though I've run into problems like this, I'd be having a far worse
time without it.
Regards,
Robert.
