January 19, 2005 How can i get a smaller program? | ||||
---|---|---|---|---|
| ||||
I use dmc8.41 and wxwidgets 2.4.2. I build the lib use \src\msw\makefile.sc. then write a simple app just show a frame. but the app size 1.2M, with -g the size grow up to 1.7M. but with VC++6, only 500K, how to reduce the applicatin's size? |

Posted in reply to chris elliott | Thanks a lot.
I have seen the table before. But I note you didn't mention the size under
release configuration with Digital Mars.
The makefile in the wxwidgets without a releaseconfiguration. I'm not
familiar with the bakefile, so I modify the makesc.env , delete the
_D__WXDEBUG in the CFLAGS line. Make success, but the size of the lib only
shrink a little.
I don't know if this is a right way.
I'll try the setup.h later time.

Once you've done that, it should be significantly smaller. You could also try using an executable compressor like UPX to make your executable even smaller. |

Posted in reply to Michael Hagley | you might like to look at http://biolpc22.york.ac.uk/wx/wxhatch/wxMSW_Compiler242_choice.html (see also http://biolpc22.york.ac.uk/wx/wxhatch/wxMSW_Compiler_choice.html where the bakefile build system was used) My impression for 2.4 is that the differnces in size between linkers soon disappear when the size of your program starts to increase; with the minimal sample there is a ratio of 1:4 in sizes, but for my more complex test case (wxhatch) the ratio is much smaller The usual answer to making the file smaller is to turn off the parts of the wxW library in setup.h (hint: remove all the setup.h files you can find, edit setup0.h, and recompile the library chris Michael Hagley wrote: > In article <cskjgu$bl5$1@digitaldaemon.com>, danny says... >> I use dmc8.41 and wxwidgets 2.4.2. >> I build the lib use \src\msw\makefile.sc. >> then write a simple app just show a frame. >> but the app size 1.2M, with -g the size grow up >> to 1.7M. >> but with VC++6, only 500K, how to reduce the >> applicatin's size? >> >> > > You can strip the executable of the symbol table and relocation bits by using > the "% cc -s yourapp.c" command.

This can not always be recommended, however, for production code (meaning programs you want to sell). It's not the fault of UPX, but I remember there have always been problems caused by buggy or too aggressive heuristics of anti-virus software. Of course, you don't want your customers to get a virus warning from your program (even if it's a false one). All of the above is IMHO. ;-) Def |
