New install of sagetv MC. Followed instructions. wrong ELF class: ELFCLASS32

[kireol]

I just purchased the media center for linux.

I followed the instructions step by step.

When i run the server I get:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/sagetv/server/libSage.so: /opt/sagetv/server/libSage.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Any ideas? Can Sage not run on a 64 bit operating system? How would I go about fixing this without downgrading my system and eliminating nearly 9 gigs of RAM?

I think you need the 32 bit version of java. Sage is a 32 bit application AFAIK. (I use Windows though so maybe it's different for Linux).

OK thanks. Hey I'm from Royal Oak. Small world.

It looks like this problem has existed for more than 4 years from what I've read. I hope the dev team is working on a 64 bit version. Most 32 bit OSs are getting phased out.

The simplest thing to do is to just install the 32-bit version of Java outside apt/dpkg. I gave detailed instructions to somebody else here:

I sshd home and followed your directions.

sudo ./startsage 
Changing to SageTV directory /opt/sagetv/server/.
Executing pre-scripts
Starting server mode

ps ax | grep java
24040 pts/8    Sl     0:03 java -Dsage.paths.tools=/opt/sagetv/server -Djava.awt.headless=true -DUSERKEY=....

no errors!

While I need to go home and run the client to make sure it actually worked, I thank you!

Honestly Sage should give you a free extender or something. They saved a customer

Glad I could help.

SageTV really needs to provide a 64b package, a better installer, or maybe both.

they need AN installer. hah. but yeah, agreed. 64bit package would be nice.

[bcjenkins]

They do provide an installer in the debian package.. IMO - it is not optimal as it runs as root and is only targeted to 32-bit machines.

I did not see a 64 bit installer. And I looked all over. With more and more people switching to 64 bit OSs due to RAM limits and soon for hard drive limits, it's important to know your market.

Since SageTV does not need to address a large amount of memory there would be little advantage to going 64 bit. In fact going 64 bit would simply increase the memory requirements since all the pointers in the JVM would be twice as large.

But I agree it is a bit of a pain that you need to find and install 32 bit libraries just for sage but as the linux version was always targeted at VARs who would likely prefer the 32 bit version anyway.

Agreed that sageTV itself doesnt need a lot of memory. But with todays computers, you can run many many things on the same computer, where now you would need a lot of RAM. My server sits around 9 gigs used average constantly for example.

The advantage is that the 32b code is starting to rot, especially the 32-bit shims that allow running 32-bit executables on a 64-bit kernel. By providing a 64-bit binary, they get the advantage of using the most tested path (x86_64 app / x86_64 kernel) and avoiding the least (not at all?) tested path (ia32 app / x86_64 kernel). AFAIK, SageTV is the only PVR app that uses these legacy 32 bit code paths, and they're basically not tested at all by linux driver developers.

As a case in point, I remember a huge spate of problems a year ago or so where some driver didn't work with SageTV on x86_64 hosts due to a bug in the ia32 compat shims. I think it was Brandon who was having the problems..
