compiling a win32 sim from linux

[lights0ut]

I'm trying to follow the wiki's instructions on how to compile a win32 simulator. I've installed mingw32, I've rebuilt SDL and put it in /usr/local/sdl32, and put that directory in my path. I do the regular make and make install, but when it's finished it's still a linux sim, even after I do the stripping commands at the end.

What am I missing?
thanks

You've installed a linux cross compiler on your PC?

[lights0ut]

I don't quite get what you're asking. I use linux as my OS, so it is easiest for it to be my build environment. When I go to build the sim it says it is using gcc 4.x.x , do I need a different cross compiler?

[bluebrother]

when building for any other platform than your native one you need a cross compiler. Like you need a cross compiler for building Rockbox you need a cross compiler when building the sim for windows from within linux.

i see, is that the mingw32 package that I installed following the instructions on the wiki?
how do i get the configure script to use mingw32 instead of gcc?

[GodEater]

It might be as simple as editing the Makefile that the configure script generates, and replacing the value of the CC= with the mingw32 binary instead of gcc. Or it might not. I've never tried this so I'm not sure.

You will probably also need to cross-compile libSDL and install that locally.

thanks guys
Godeater: will try that later today, hoping it's that simple
linuxstb: thanks for looking out for me, I've already compiled SDL with mingw32  

[lights0ut]

Hey guys, I got me a windows sim. Turned out that when I read the part about setting the path to the win32 style SDL i forgot to add 'bin' at the end of PATH=/usr/local/sdl32/ .
Reminds me of when I was doing HTML in high school and I would spend an hour realizing I forgot a quotation mark.

Thanks for all the help

evilg123: what dev environment are you using? Linux natively or Windows/VMWare/Debian, Cygwin, CoLinux,etc?

Would you mind putting the steps in a wiki page?  I can edit with screenshots after I try it out.  

I wanted to know how to do this a while back, but didn't know how to go about installing the cross compiler or which one to install.  Cygwin is considerably slower when compiling builds than VMWare.  I'd rather use the latter but like the Win32 sim convenience.  

Mostly I just patch and compile to update rockbox and work on WPSs.

Thanks in advanced.

Hey Nate!,
to be specific I use linux to compile my builds natively, I use the kubuntu 6.10 (edgy eft) distro ( (k)ubuntu is based on debian).
 I just use the rockboxdev.sh script to get the required compilers etc.

Personally I think that if you're serious about compiling you should be running linux, it is the fastest, and can compile linux and win32 sims.
VMware is faster than Cygwin but as you stated, it can't make a win32 sim (as far as I know).

There is a wiki page on how to compile the UI simulator with  a section on how to compile a win32 sim from linux
check it out here

if you're wondering which compiler you need to make a win32 sim from linux, first you need to install mingw32, then you need to build SDL with mingw32 and install it in somewhere other than /usr/bin (assuming this is where the linux SDL is installed) I use /usr/local/sdl32. This is done by typing

 ./configure --host=i586-mingw32msvc --prefix=/usr/local/sdl32

after that's done, cd to your build dir as usual, but before you run configure you need the new sdl in you path
so:
PATH=/path to new sdl/bin:$PATH    for me this is         PATH=/usr/local/sdl32/bin:$PATH

after configure and make and make install is done then you need to run the following
find -name "*rock"         -exec i586-mingw32msvc-strip "{}" ";"
find -name "*codec"        -exec i586-mingw32msvc-strip "{}" ";"
find -name "rockboxui.exe" -exec i586-mingw32msvc-strip "{}" ";"

and then you're done! you have a nifty win32 simulator.
hope that helps

I'm thinking that if I do follow all of the steps that you've described in a VMWare/Debian setup, I should end up with the same results.

I can't commandeer the family pc.  My wife and daughter would kill me.  Can't go dying over me trying to compile a Win32 sim.  

No seriously, I want to ease slowly into the Linux world.  Just haven't taken the plunge yet.

Thanks for you advice.

If you install the appropriate packages VMWare should work.

[lights0ut]

If you install the appropriate packages VMWare should work.

you're right, I suppose you could apt-get from VMWare couldn't you.

[Llorean]

The apt-get is a little... unreliable. But in *theory* you could manage it, yes.
