Hello!

Beacuse no one replied, I thought that it might be useful to spend the whole night with googling, and searching the answers for this cross compiling :)
Now it somewhat clearer for me, what should I do.
I found a new howto, which explains this thing a little bit simpler. Now I realized, that lazarus need these tools (asw, dlltools etc...) to compile the project to win32. I think that those utils will be there, after I compiled my new gcc, as I read it on the web-page (am I right?). My problem is that I can not compile the new gcc(3.3.1). When typing make, it says after a while that it can not find the sys/sysctl.h header file. Well it is in my /usr/include dir, but gcc can not detect it, because of the configure parameters I've added to it before the make. I tought that I could solve this, and symlinked the /usr/include/sys dir, to the gcc-source's include dir. Now the make found the sysctl.h file, but it reported that another .h file is missing. So I linked another (/usr/include/linux) dir to the gcc's include dir, and now the make finally went thru this phase. But then it wrote some error messages which I can not understand, and I thought maybe you could help me. So, here is the make's output:

I hope someone can understand these error messages, and can explain me, how to compile this gcc, and then finally, I will be able to compile my project to win32.

Thanks for the help!

Daniel

Ehm... do I get this right here ? Are you creating a win32 executable and running it in Linux ? That won't work.

Marco van de Voort �rta:

Thanks for the lot of help, now I realized, that I already have those ldw, asw binaries which are needed by lazarus, because the howto told me to compile a new binutils. Then I just don't understand why it told me to compile the gcc... So I've copied those binaries to my $PATH, and set up lazarus to build to win32, and set up the LCL to win32. Please allow me to paste the lazarus's output when I try to compile my project to win32:

As you can see, my lazarus has been closed. After I clicked the Run button, I could read the messages window, and it told me that, the "Project "project1" Succesfully built :)". But, right after that, all of the lazarus's windows closed. I have compiled lazarus by hand, but I'm using the precompiled version of fpc(ppc386) v1.0.10.

I think I can ignore these lines:
TOutputFilter: "Hint: Path "/usr/lib/fpc/1.0.10/units/win32/" not found" TOutputFilter: "Hint: Path "/usr/lib/fpc/1.0.10/units/win32/rtl/" not found"

because I have installed those libs to an other directory, and I specified this in my .fcp.cfg:

-Fu/home/leva/FreePascal/lib/fpc/1.0.10/units/$target -Fu/home/leva/FreePascal/lib/fpc/1.0.10/units/$target/* -Fu/home/leva/FreePascal/lib/fpc/1.0.10/units/$target/rtl

So I think lazarus found the win32 libs, after searching in these pathes.

But to take no risk, I have symlinked that win32 dir to /usr/lib/.... directory, and tried to Run the project again, and the same happened: lazarus has been terminated.
The error messages are not the same every time, so I paste some other messages as well:

I'm running Debian/woody, with glibc_2.2.5-11.5, and: libgtk1.2 1.2.10-11
libgtk2.0-0 2.0.2-5woody1

libglib1.2 1.2.10-4
libglib2.0-0 2.0.1-2

ppc386_1.0.10
lazarus 0.9.0

The binutils that I've compiled to get that asw, and other binaries, is 2.14.

If I'm using the "Run / Build" menu only, then lazarus builds my project, and I can run the output binary under windows. Is it normal that the output binary is very big? I mean, there is nothing in my project, but a plain form, and the windows binary is 3mb ( and under xp, an ms-dos window pops up with the project, I don't know if this is normal...).
The bigger problem is, that lazarus terminates when I click Run. Or is this because Lazarus can not run windows executables, and somewhere in the options, I must specify i.e. a wine binary?
Is this some kind of bug in lazarus, or this is squarely my fault, or my system's fault?

Thanks a lot!

Daniel

You don't need gcc. You are looking at compiling C programs cross platform with gcc.

You don't have C programs, you have Pascal programs (FPC). So you need a cross pascal compiler.

However it happens that FPC can generate code for all operating systems on an architecture using one binary. (ppc386 in this case)

What you need are cross binutils. These are on ftp (freepascal.stack.nl), and if you need to hand build them, see the script in the fpc source repository (fpc/install/cross)

Then you need to compile the parts of FPC that are OS specific (the libraries) for win32. In the same CVS dir (fpc/install/cross) there is script that does just that.
