Hello! I've recently migrated from VC++ to MinGW (to try!) and I have 2 questions : 1) I would like to understand why when I build an exe with VC++ which is about 24 Ko, the same is more than 430 Ko with gcc! (this when I use iostream, with printf() this is about 22 Ko) 2) I've the Warning "no new line at end of file". Why this is important for gcc ??? thx. [edit: third question ;p] 3) My program is composed of 3 files: main.cpp, bitmap.cpp and bitmap.h. main.cpp includes iostream, iomanip, fstream, string, time.h and "bitmap.h". bitmap.cpp includes fstream and "bitmap.h". bitmap.h includes nothing. there is no include of a windows file header anywhere. However, when I put the definition of tagBITMAPFILEHEADER, tagBITMAPCOREHEADER or another struct from wingdi.h, I get an error that it was already defined in wingdi.h! Where does it come from? Is wingdi.h always included with mingw??? (I wish someone understand me :F My english is not very good) [edited by - V3rt3x on December 6, 2002 4:05:42 PM] [edited by - V3rt3x on December 6, 2002 4:23:14 PM]

ok but how can I reduce the executable size?

Use the optimization switches.
