hi. Pity on me. Cross compile request. Jnotify

twobob · 12-11-2012, 12:35 PM

Hey. I just am having no fun with my cross compiler again.

Pebcak.

Don't suppose some kind fool out there could cross compile these measly two files for me could they?

Jni.h hates me.

Target Kindle 3 (so java 1.4 blah de blah I guess if that matters)

I would be mightily appreciative. (expected output is a shared.so)

yours humbly. me.

@twobob: Fix the path to your JVM rootdir in Release/subdir.mk (and, actually, fix every gcc call in the few makefiles included, they default to 'gcc', hardcoded).

twobob · 12-11-2012, 01:53 PM

I fixed up the gcc. I link the shortnames.

okay I will give the JVM rootdir thing a fix! perhaps that will fix it.

Cool stuff... can you please report back if it actually works to monitor directories under /mnt/us? (And maybe even on the Touch/Paperwhite?)

I intended to use jnotify for JBPatch, but miserably failed and gave up on it. I think it was because some kernel symbols weren't found, or so... or maybe because FAT32 isn't supported... Whatever, can't remember, but it'd be awesome if it could be used.

Even natively, it's a bit messy over the userstore. Going behind fsp's back helps a bit.

Hehe, thanks. I guess I'll stay with my homegrown solution then

twobob · 12-12-2012, 07:16 AM

^ Insert swear words here.

Didn't even make it past the first hurdle. "Running"

Will revist. (and then look at your two's solutions as they actually work)

unknown type name 'loff_t'

I got that far at long last...

clues Monsieur Niluje?

Long Offset Type?
Probably has to do with "large file support (64bit file addresses)"

Might be missing from your include chain, perhaps optioned out by having "large file support" disabled somewhere.

twobob · 12-12-2012, 10:38 AM

gah. : ) Niluje came across this when he built it.
Sadly his skillage exceeds mine to the power "craploads"

erm... maybe its a gcc flag?

or maybe I need to check #include <sys/types.h>
will go dig

EDIT: Added types call in headers files

and

Code:

#elif defined (__arm__)
#if !defined (__NR_inotify_init)
# define __NR_inotify_init	316
#endif
#if !defined (__NR_inotify_add_watch)
# define __NR_inotify_add_watch	317
#endif
#if !defined (__NR_inotify_rm_watch)
# define __NR_inotify_rm_watch	318
#endif

in syscalls.h until I know if it wants the 0x900000 offset or not...

knc1 · 12-12-2012, 11:16 AM

That reads as if your toolchain is picking up the host's sys/types.h rather than the target's sys/types.h
(ARM and most risc are different in a few details)

Someone asked on here recently if it made a difference which sys/types.h was used.
Answer: (days late) YES, it does.

gcc -E ...
Will show you the full paths of the include files being picked up.

twobob · 12-12-2012, 12:24 PM

seems like I need to retroweave the released jar to test it in action.

me@dev /usr/local/src/retroweaver-2.0.7 $ java -cp "/usr/local/src/retroweaver-2.0.7/release/retroweaver-2.0.7.jar;/usr/local/src/retroweaver-2.0.7/lib/asm-3.1.jar;/usr/local/src/retroweaver-2.0.7/lib/asm-commons-3.1.jar" net.sourceforge.retroweaver.Weaver -jar ./jnotify-0.94.jar ./out.jar
