Greetings- I am running Yellowdoglinux(a redhat variant for powerpc) and am trying to use Vpython. My version of linux does not have the gtkgl. The FAQs for Vpython point to the redhat site. From a CD of the most recent redhat, I used the gtkglarea.... but that needs the ld.linux.so.2 which is not present. Any suggestions? Is there a version of these libraries that i can use without this dependency? I have downloaded the python 2.2, and found the other modules needed, but cannot seem to get around this one. Thanks.

I don't know anything about Yellow Dog Linux, but perhaps you could compile gtkglarea from source? |

David- Thanks for the suggestion. As I am new to Linux, how would I do that. Is the source available on the redhat site? Thanks. ocleman David Andersen wrote: > I don't know anything about Yellow Dog Linux, but perhaps you could compile > gtkglarea from source? |

I've never built it myself but I did look to see if it was available: www.rpmfind.net has a gtkglarea-1.2.3-2.src.rpm, which I assume is the latest version. |

Follow-up: I just did a quick check... Apparently there's a program called rpm2cpio that converts for you. The example I've found shows: rpm2cpio package.i386.rpm | cpio -ivd dir/subdir/filename it creates the path structure in your current directory and extracts the file to that (i.e. "filename" ends up in "./dir/subdir" as you'd expect). -- Kevin Cole, RHCE, Linux Admin | E-mail: kj...@gr...

You can extract, compile, and install directly with the 'rpm' command once you have the archive: rpm --rebuild gtkglarea-1.2.3-2.src.rpm That will not only extract, compile and install it, it will also leave a binary package (gtkglarea-1.2.3-2.rpm) sitting in a directory under /usr/src/redhat somewhere. The extraction and compilation gets done under there too, but I can never remember exactly where, it's not hard to find. Not that I've actually managed to get Visual working under linux - I tried ages ago with older versions of Visual and Redhat, and gave up after hitting a morass of dependencies. I already had it working under windows anyway... On the topic of extracting the contents of RPM's without 'rpm' or 'rpm2cpio', I'd say it would be tricky without digging through source code for the file format. Easiest just to extract a source rpm on a redhat box using rpm, then find and copy the sources off from /usr/src/redhat to wherever you want them. Andrew -- Dr Andrew Williams an...@ph...

Thanks to all of you for your replies. I'm closer but is is not working yet.
With rpm2cpio, it did not seem to translate. I donwloaded the ...src.rpm
and converted it. The original make produced an error that there were stray
"\" in the file cvisual.cpp. This was actually a problem listed on the
vpython archives from last Nov, unfortunately the solution for that person
was to use the binary code. Catch-22 for me.
So I edited the file mad delted the stray backslashes. Below is the new
error message. I do not know c,c++ beyond minial use so do not know how to
correct the source file.
Ths current version of this file is also attached.
Any suggestions or corrections would be appreciated. It seems that this is a
bug for any linux OS (see the nov message if interested) trying to compile
from source rather than binary.
Thanks for the assistance.

I do not think the backslashes you deleted were "stray backslashes".
They continue a line in a macro expansion by "escaping" the subsequent
line feed character. What you are probably seeing is a file with
Windows \r\n line terminators. The preprocessor sees "\\\r" and
complains.
You can probably fix this by replacing the backslashes and fixing the
line terminators. There's a script that comes with Python to do it;
there are also common tools like 'dos2unix'; and in a pinch you can roll
your own with something like
x = re.sub(r'\r\n',r'\n',open('cvisual.cpp','rb').read())
open('cvisual.cpp','wb').write(x)
In a pinch, just delete the backslashes and cram the whole CALLF macro
onto one line.
