Gargoyle – another IF player

[pete330]

The provided new git, glulxe, etc. files won't work with the old firmware (they require at least firmware 5.6.5), a specific build has to be created.

The source code itself is "ready" for the old firmware, so it is "just work" to cross-compile an executable for the old firmware.

Here is the txt file.

Hi Manny, thanks for the info! Only libjpeg and libpng are outdated.

@Moderators: Is it ok if I post the newer versions in this thread?

Just check if their license allows it.
I think they are both open source, if so, go ahead.
(No need to build them, just pull from Debian/Jessie/ARMel packages.)

But as I posted above, your duplicating effort, they are already posted in this forum, somewhere.
It should not be too hard to find them with our advanced search.

[pete330]

I would simply pull them from my kindle PW3, they are open source.

Sounds good to me.

I am not a moderator, but we don't have a moderator in this forum any longer.
The ones listed are dead, dying or just gone somewhere.

Hi,



here are the missing library versions for devices with firmware version < 5.6.5:



Please unpack (tar xzvf ) the attached archive & copy the 2 contained files into this directory:



/mnt/us/extensions/gargoyle/dist/



Don't forget to check file permissions of the two new libs. -rwxr-xr-x ist required, it can be set with chmod 755 .





Does this resolve the problem?

[Manny_Belano]

Hi, pete330,

I've tried what you said, but it didn't work. I'll detail what I did.

1) I unpacked the archive and put the two libraries in /mnt/us/extensions/gargoyle/dist/

2) I used the command ls -l to see if I have the file permissions as you said:

ls -l gargoyle/dist/libjpeg.so.8
-rwxr-xr-x 1 root root 195352 Apr 18 05:32 gargoyle/dist/libjpeg.so.8

ls -l gargoyle/dist/libpng16.so.16
-rwxr-xr-x 1 root root 160344 Apr 18 05:30 garyoyle/dist/libpng.so.16

They look allright, from what I understand from your post and of some pages I read, but, like I said before, I'm a newbie.

3) I execute gargoyle.sh, but again i was returned to the kterm enviroment, with this answer:

gargoyle/gargoyle.sh
./dist/gargoyle: /lib/libc.so.6: version 'GLIBC_2.17' not found (required by /mnt/us/extensions/gargoyle/dist/libgarglk.so)
./dist/gargoyle: /usr/lib/libz.so.1: no version information available (required by /mnt/us/extensions/gargoyle/dist/libpng16.so.16)

After that, I create a new GarglkDependencies.txt file, that I attach to this message.

If you are going to run this under an Amazon firmware built against an older GLIBC, then you will have to follow the procedure demonstrated in my "ARMhf" thread.
That explains and demonstrates how to run more than a single system library, concurrently, on an ELF system.
or
Either that, or ask Amazon/Lab126 to release a firmware build against a newer GLIBC.
or
Just build gargoyle against the older glibc.

PS:
Those listings are not correct in that they cover more than just the gargoyle dependences.

readelf is probably the weapon of choice although there are others:

readelf -a <your bin here> | grep 'NEEDED'

Hi, friends,

I read your post and thread, knc1, and other articles regarding what you're saying. So I think I understand the problem: even if I copy the new libraries, the kindle will check the old ones. But I try to understand how to solve this and, well, I must say I don't understand much. I've never worked with unix, and from what I read this is a must to know how to solve this. I've never compile a program neither. So, for now I least, until I have more time to learn how all this work, I give up.

Thanks again, both of you, for the patience, the help and the clarity of your explanations.

How a *nix system handles an ELF format set of binaries is very much different than how other systems handle a PE format set of binaries.

It is not overly complex, just different.

Can you post the output of these commands from your Touch, please:

uname -a
ls -l /usr/lib/libjpeg*
ls -l /usr/lib/libpng*
ldd --version
/lib/libc.so.6

I guess you have the latest Touch firmware?

I'll try to compile a version that'll run on Touch and PW1 (FW 5.6.1.1), too. But it may take a while.

[Manny_Belano]

Hi,

Yes, I have the latest touch firmware: kindle 5.3.7.3 (2715280002).

Here are the commands with their respective output:

uname -a

/lib/libc.so.6
/bin/sh: /lib/libc.so.6: Permission denied

[knc1]

Your running as root, chmod the libc to allow execution (safe to do) and then execute it.
(chmod +x /lib/libc.so.6)
(Yes, It is a library but it is also an executable. you'll see.)

[Manny_Belano]

Thanks for the tip, knc1.

Well, I tried what you said, and I have this output:

chmod +x /lib/libc.so.6
chmod: /lib/libc.so.6: Read-only file system

After that, I try the next thing:

chmod 755 /lib/libc.so.6
chmod: /lib/libc.so.6: Read-only file system

So, after that, I used the next command:

ls -l /lib/libc.so.6
lrwxrwxrwx 1 root root 14 Jul 20 2015 /lib/libc.so.6 -> libc-2.12.1.so

And then, just in case:

ls -l /lib/libc-2.12.1.so
-rw-r--r-- 1 root root 1181108 Jul 20 2015 /lib/libc-2.12.1.so

If I try again to run only

/lib/libc.so.6


the I have the permission denied message appears.

What I'm going to say is pure speculation, so correct me if I'm wrong. "libc.so.6 -> libc-2.12.1.so" means that libc.so.6 is being redirected to libc-2.12.1.so? For that and because libc-2.12.1.so don't have permission, even if I have permission for libc.so.6, I have the permission denied error? So, I have to chmod 755 libc-2.12.1.so? Obviously, all this explanation can be totally wrong. If that so, pay no attention to this.
