 1. Compilation under Dev-C++ is too slow#2322 Posted by: 2003-06-18 01:38:17 |
I am using Dev-C++ 4.9.8 and mingw compiler. i installed wxWindows using DevPaks. but it takes a lot of time ti compile a simple program. i literally stopped using wxWindows because of this.
Is there any kind of PCH (Precompiled Headers) support for Dev-C++. or any work-around for this problem.
thanx in advance |

It's a well-known GCC problem, a cost of free you must pay :)
Actually, it's a cost of code optimization. I heard GCC is a compiler who does the most comprehensively optimization. |

wxSamples/calendar/calendar.cpp (one cpp file) takes here 21seconds
wxSamples/artprov/artpro.cpp (two cpp files) takes here 31 seconds
I only have a 1200 Duron with 133 MHz RAM Bus. I know machines 5 times
faster than mine :), so one can suppose that these 31 seconds will in, a close future, be reduced to few seconds ; let's say less than 5 seconds ?

| If don't want to change the compiler, one thing we can do: divide the source into smaller cpp files, although this need better structured header files. Then, F9 or Ctrl-F9 will only compile the changed files, but the link time won't be saved. |

Also, I believe that including wx.h as a whole will greatly increase compile time, especially in multiple source files. Including ONLY those .h files for the controls you need will also speed up compile times...

Sounds a bit strange. I'm on a Athlon 800 and it takes about 5-10 sec to compile these.
Have you enabled debugging info or profiling?

Well ! Here is my makefile for arttest (40 seconds today :)
I am new to C++ and new to wxWindows, not professional
and rather old ... so ...

Here is a possible solution that I use. (At least until gcc 3.4 is out and we have precompiled headers).
First I download dev-c++, wxWindows, and Borland's (yes, borlands) command line tools. I unpack wxWindows and compile with bcc. I then copy one of the makefile.b32 and <filename>.rc files from one of the samples, edit and rename them and throw them into my project directory. Then, to compile, I keep a cmd window open and just type make -f makefile.b32 (or up-enter) whenever I want a new binary, and I get the speed of borland's compiler and the usefullness of dev-c++ |
