--- Comment #64 from PcX <xunxun1982 at gmail dot com> 2011-06-08 14:26:05 UTC --- I found that the shared or static gcc edition made a great difference of the wx unicode release mono dll size. ----------------------------- At first, I build the gcc 4.6 with "--enable-static --enable-shared", and then I use the gcc edition to compile wx2.8.12 unicode release mono dll, that is, mingw32-make -f makefile.gcc CXXFLAGS="-Os -fno-keep-inline-dllexport" LDFLAGS="-static -Wl,-s" this gcc edition can produce the wx dll size about 6-7M, and the dll depends no any gcc dll. ---------------------------- Another day, I build the gcc4.6 with "--enable-static --disable-shared", and then do the similar thing, that is, mingw32-make -f makefile.gcc CXXFLAGS="-Os -fno-keep-inline-dllexport" LDFLAGS="-Wl,-s" this gcc edition can produce the wx dll size very large, about 17M, and the dll depends no any gcc dll, too. ---------------------------- That's why? Thanks.
