compiling problems with windows me and cygwin

SamAdam · Post by **SamAdam** » Sat Oct 23, 2004 3:38 am

hey everyone, I am attempting to compile blender with cygwin. You need not point me to Appleman's tut, I am following it currently. I installed cygwin, with all the packages advised, i got the cvs, i tried to "make" but it failed after about 20 minutes with what seem to be memory errors. I can't find any blender specific terms in the error readout, nothing to help me identify a problem area in the source.

I can provide any information needed.
my stats:
PIII 733 (zoom!)
128 mB ram, usually 192 mB, but apparently one is not being detected.
Win Me (not my choice, family computer)

I really want to do some work on the sources and get some personal daily builds. Thanks, SamAdam

what seem to be memory errors.

Knowing what the error msgs actually are helps in debugging a problem. This is a general rule.

/me guesses Win ME is running out of system resources. If you are getting memory errors, it has nothing to do with Blender.

Try shutting down Word, Explorer, AIM, Unreal, and all the other things you are running when you compile.

The fact that one of your memory sticks is not being detected does not sound good.

I did a cygwin compilation too yesterday .
p4 at 3.2ghz
1 giga ram
winxp pro

okay.
about the ram: my computer is strange like that. sometimes the full 256 mb appears, sometimes not. Sometimes my processor is clocked differently. About every other time I boot up I get a different proc speed. Yesterday my 733 booted up at 900 mhz. most of the time it is around 866.

idk...

i think that closing the other program I had running might work.
i will check back later.

Search thru the compile output looking for lines that say 'No such file or directory'. Either you do not have something installed and the file is missing or you do not have the include paths properly set and make cannot find it.

No problem if I delete in this file all the refs to the png.h . It results a compilation without screen saver for the gameengine.

If I correct the path to " png.h" then error are multplied
by 4... It seems that the script is C compliant but not C++.

okay, well, here is what I got after I tried to close all the other applications

that is just what is visible in my command console.

any thoughts?
i got a lot farther than before.

Open the GPC_Canvas.cpp file and remove the two last active functions .

SamAdam · Post by **SamAdam** » Tue Oct 26, 2004 3:10 am

which of these should i delete jms?

Code: Select all

	// write the file header information
	png_write_info(png_ptr, info_ptr);

	// allocate memory for an array of row-pointers
	row_pointers = new (png_bytep) [(GetHeight() * sizeof(png_bytep))];
	if (!row_pointers) 
	{
		std::cout << "Cannot allocate row-pointers array" << std::endl;
		longjmp(png_jmpbuf(png_ptr), 1);
	}

	// set the individual row-pointers to point at the correct offsets
	for (i = 0; i < GetHeight(); i++) {
		row_pointers[GetHeight()-1-i] = (png_bytep)
			((unsigned char *)pixels + (i * GetWidth()) * bytesperpixel * sizeof(unsigned char));
	}

	// write out the entire image data in one call
	png_write_image(png_ptr, row_pointers);

	// write the additional chunks to the PNG file (not really needed)
	png_write_end(png_ptr, info_ptr);

	// clean up
	delete [] (pixels);
	delete [] (row_pointers);
	png_destroy_write_struct(&png_ptr, &info_ptr);

	if (fp) 
	{
		fflush(fp);
		fclose(fp);
	}
}

and there we have it. I got it compiled, and I am rather proud of myself. I have to go work to work now, so expect something from this. Thank you jms and everybody.

Looks like some path is wrong, since cl.exe is not found...

in fact, we have just to copy :
..\bf-blender\lib\windows\png\include\ - png.h - pngconf.h
..\bf-blender\lib\windows\zlib\include\ - zlib.h - zconf.h
in :
..\bf-blender\blender\source\gameengine\GamePlayer\common\

(found by laume on a french forum)

The problem has already been fixed, and both SCons and make are updated for the fix, too. No need to hack around anymore.

i tried compiling the 10/27 build and I got the same failure. I don't know what it is looking for in the microsoft visual studio area, i don't have any of that installed. I was just about to get to work, too. Any ideas?

and can someone give me a quick tut on applying patches?
