minimum wxWidgets application size with static linkage
in [wxWindows]
|
From: Lars Uffmann on 25 Jan 2008 05:13 Hi everyone! As you probably saw in my other thread, I only just managed to configure my eclipse CDT to compile and link wxWidgets libraries with the managed make project. Now it appears to me that my current settings statically link a massive overhead from precompiled DLLs, stuff that I don't need, boosting my executable for wxWidgets-2.8.7/samples/minimal/ to the enormous size of ~27MBytes. Btw, this is just slightly bigger than Cywgin links it with g++ minimal.cpp `wx-config --libs --cxxflags` -o minimal.exe So here's my question: Can I - and if so, how - massively reduce the file size for an executable standalone wxWidgets-application by statically linking only the classes/methods that I _really_ need in my project? Is it possible to extract that functionality from precompiled libraries? I guess not, and that would mean that I have to include the wxWidgets sources in my project, instead of precompiled stuff, wouldn't it? Thanks in advance! Lars

No, it isn't helping :/ Unless that really means I have to manually edit every single define statement in the setup.h header file. I was definitely not looking for options to optimize size vs. speed, and definitely not looking for suggestions to dynamically link libraries (my OP stated that I believe) - merely for a possibility to drop all the functionality that I do not need at all. From what I can tell, I'd have to exclude all those libraries not only from linkage, but also #define the appropriate flags as 0 in the setup.h - that's hardly convenient. Edit: Just removed all the libraries that wx-config --libs links from the statement and manually built minimal sample and apparently it doesn't decrease executable size by one bit. Sooo - what's the minimum size of a standalone(*) wxwidgets executable? 1MB? 5MB? 26MB??? Anyone? :) Best Regards, Lars PS: And by standalone I mean that it comes with all the USED wxwidgets related functions/classes statically linked

That's the way, the linker is completely hopeless at removing code you don't use chris --------------------------------------------------------------------- To unsubscribe, e-mail: wx-users-unsubscribe(a)lists.wxwidgets.org For additional commands, e-mail: wx-users-help(a)lists.wxwidgets.org
