wxDev-C++ 6.10: can't compile DLL's Topic is solved

[alocin]

Hi,

I have just installed the new 6.10 beta version, and I have tried to create and compile a new DLL. I have just opened a new project, selected DLL, and compiled the project skeleton as created by wxDev-C++.
With the previous 6.8 version I have no problem, but now the compiler show this error message:

C:\aijen\CT\NuovoCompil\Makefile.win [Build Error] exe: *** [MingW/Progetto1.dll] Error 1

The entire compiler log is this one:

Compilatore: Default GCC compiler

BTW I have not changed the project options. All is like wxDev have created automatically.

Someone can help me? Any suggestion?

[tbreina]

You're right. The makefile is being generated wrong. It shouldn't be pointing to Project1.a.

I'll see if we can't correct this over the weekend.

Thanks for the report.

Alocin,

I've got a possible fix for this. Would you be willing to test it (or anyone else that uses DLL generation for that matter is welcome to test)?

Thanks.
-Tony

[Samuel G.]

I got exactly the same Problem. Wonder, why we two seem to be the only ones, who have it (OK, I erred.).

So, where is the Fix? I am willing to test it!

[lowjoel]

Fixed in CVS. Alpha available at http://joelsplace.sg/projects/wxdsgn/. Please look at the notes on the page.

I'm getting the identical error using 6.10.2 stable. The import library isn't generated:

This was a test using an empty default dll template project, but an actual dll project that built successfully with 6.10.1 now fails in the same way. Strangely, I tried swapping devcpp.exe back to 6.10.1.152 but still get no import library.

After looking at a successful code::blocks compile log and changlng wxDec-C++'s makefile.win as follows:

Code: Select all

STATICLIB= "MingW/libProject1.a" #explicit declaration just for the sake of clarity
...
$(BIN): $(OBJ)
	$(LINK) -shared $(LINKOBJ) $(LIBS) -Wl,--out-implib=$(STATICLIB) -o $(BIN)

I was able to get it to link on the command-line.

Looking at the original makefile, I can't seem to find where/if $STATICLIB is defined. I wonder if the problem was solved by defining that variable or by chaning the --implib to --out-implib (or both)? Could you do a test to see?


Thanks.

[aval57]

$STATICLIB wasn't ever defined originally, though the literal string was supplied so I doubt if that had anything to do with it.

It appears to have to do with the '=' in the import library option. Both "--implib=$(STATICLIB)" and "--out-implib=$(STATICLIB)" work, but not "--implib $(STATICLIB)" or "--out-implib $(STATICLIB)"
