SCons errors

Building with GCC under Cygwin SCons is generating the following.

scons: building terminated because of errors.

Looking at the dna.c file its contents read, "ERROR! Cannot make correct DNA.c file, STUPID!" At the risk, looking at the Tuhopuu tree there is another DNA.c file with the filename in uppercase and the SCons built file's name is lowercase. Since Linux is case sensitive it seems like there may be a connection. However it's a guess. There is, in all likelyhood, something misconfigured in this setup.

Cygwin is installed with the full package. All components are default installation. SCons was built and installed from the downloaded tarball under Cygwin.

It says that "Can't read file source/blender/makesdna/DNA_listBase.h" is the problem. Make sure that DNA_listBase.h exists in the correct place and isn't corrupted. Or it may be a path issue "home/mame/build/build/cygwin/source/blender/makesdna/intern/dna.c" , thats a correct place issue.

Hi, Michaelv. Thanks for the reply.

DNA_listBase.h is located in "C:\cygwin\home\mame\build\blender\source\blender\makesdna" from the CVS.

The hi-lighted "build" directory above "C:\cygwin\home\mame\build\build" is getting created by the Blender SCons script. Blender routines are putting the files in their "build" directory. Do you suppose that's the confusion, because I've named a directory build the script is losing focus?

Cygwin is installed in the default directory C:/cygwin
Source files are installed in default "home" with a subdirectory of "mame/build"
I guess that wouldn't necessarily be default would it?
However, below "home/mame/build/" is the source directory "blender/source/".

Is SCons using absolute paths? Seems like they would be relative to the location of /blender/source/ etc. Maybe it's a Linux thing.

Sorry if I sound argumentative. This is just what's happening with the error. I'll try renaming the hierarchy and see what happens. Again, thanks for the reply.

Taking the following steps:
-Delete the "build" directory from my users login directory of "mame".
-Make clean, scons clean.
-Delete SCons "build" directory.
-CVS checkout.
-Execute scons default.
I am still no go. Again the same error

SCons is working now. I havn't really changed anything. I did download the lates version of Cygwin but other than that . . It looks like the SConscripts files are good. Thanks.

I had the same problem as you:
"Can't read file source/blender/makesdna/DNA_listBase.h"

As you did, I reinstalled cygwin, and I could pass the error.

Note: I reinstalled cygwin choosing "Unix default text file type".
The first install had "DOS default text file type" selected.
It might have been the problem!

Thanks,
kenden

Hi Kenden. I suspect if more people were using scons there would probably be more errors showing up. Glad to hear you are online.

A goodly number of the blender developers are already using SCons.

I can't help noticing that SCons errors frequently disappear once Cygwin gets installed correctly.

Hi stiv. I should have stipulated SCons with Cygwin. You are probably still correct about the goodly number. I stand corrected.

[edit] Which is, I see now, what you said in your secon paragraph. Could this post be more muddled. [/edit]

As long as we keep a sense of humor, we'll all do just fine!
