JP1 Remotes

[wnewell]

OK, I downloaded the source. Will attempt a 64 bit compile sometime in the next few days hopefully. I've got some other things going right now.

[wnewell]

Problems with compile. First attempt.

[wes@wes2 jp12]$ gcc -shared -o libjp12serial.so jp12serial.cpp
jp12serial.cpp:175:46: error: com_hifiremote_jp1_io_JP12Serial.h: No such file o

ymbol' can not be used when making a shared object; recompile with -fPIC
/home/wes/tmp/ccUZJPm6.o: could not read symbols: Bad value
collect2: ld returned 1 exit status

Second after commenting out define java line

[wes@wes2 jp12]$ gcc -shared -o libjp12serial.so jp12serial.cpp
/usr/bin/ld: /home/wes/tmp/ccmwveGJ.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/home/wes/tmp/ccmwveGJ.o: could not read symbols: Bad value
collect2: ld returned 1 exit status

Third, adding -fPIC option.

[wes@wes2 jp12]$ gcc -shared -fPIC -o libjp12serial.so jp12serial.cpp

Mind you, I have no idea what these options do, but it did compile using the above options. But, when I ran rmir, I got a pop-up about a non compatible serial driver. Don't remember the exact phrase, but it didn't like the .so file I guess. I don't know where to go from here.

[WagonMaster]

Thanks a bunch for running those tests!

[wnewell]

OK, yes, that was the pop-up error. And there wasn't a serial interface choice when the program came up.. Here's the last part of rmaster.err fwiw. Looks the same as the one using the original serial driver to me.

If you comment out the Java JNI stuff because you don't have Java headers, the .so probably won't have the entry points that RMIR calls, or they won't use the right linkage for RMIR to call them.

'wnewell', I should have mentioned this in my last post:

In case you don't have the necessary generic Java header files, you'll need to (assuming you want to deal with the bother) download the Sun Java SDK/JDK for Linux. It's about 81 MB and the one I grabbed and successfully used was a single file named 'jdk-6u16-linux-i586.bin', but there's probably a specific (different) version for a 64-bit platform like yours. I'd give you a URL, but I never can seem to easily figure out my way around the Sun Java site. You can get to it from here. You're looking for what they call the "Java SE Development Kit (JDK)". Click the orange "Download" button, then select your platform ("Linux x64").

I should iterate that with my setup (Slackware 12.1), I never needed the Java SDK/JDK to simply compile the serial library, even with the Java parts enabled (which they are by default). I only needed it to compile RM/RMIR. But you may have a different experience.

Basically, that 81 MB file is a giant self-extracting script file that you give execute permission to and then run it.

Holler if you have any difficulties.

Prior to this run I completely removed all my java on the system and reinstalled. Tested it by running rm ok. I went as far as copying jni.h and jni_md.h to the source dir. I've got about 6 hours of other things to do. Any ideas? I'll check later. I installed the sun devel package.

[root@wes2 jp12]# locate /jni
/usr/lib/jvm/java-1.6.0-sun-1.6.0.15/include/jni.h
/usr/lib/jvm/java-1.6.0-sun-1.6.0.15/include/linux/jni_md.h

[gfb107]

Try

[WagonMaster]

I can't offer anything better than Greg's sage advice.

Just for another data point, on my Slackware 12.1 installation, both of the those Java header files were in multiple locations (even prior to the installation of the Sun JDK), but the one that I think is being picked up automatically by the compiler is this:

/usr/lib/gcc/i486-slackware-linux/4.2.3/include

Both 'jni.h' and 'jni_md.h' are in that same directory, along with some other non-Java stuff.

I looked back in this thread and found no reference to the specific Linux distribution you were running. Since it may become relevant, please let us know which one you're using.

Bill

[wnewell]

None of the above worked for me, however, copying the jni files to the source dir and using -I <source dir> in cl did. Here's the actual compile.

[wes@wes2 jp12]$ gcc -I /home/wes/jp12 -shared -fPIC -o libjp12serial.so jp12serial.cpp
[wes@wes2 jp12]$ ls
com_hifiremote_jp1_io_JP12Serial.h jni.h jp12serial.cpp jp1x-serial-library-source-code-0.14.zip
gpl.txt jni_md.h jp12serial.hpp libjp12serial.so*
[wes@wes2 jp12]$

BUT , When I run rmir, there's no popups and everything looks normal, but there isn't any serial interface to select. Trying a download with autodetect results in No remotes found obviously. No errors on cl, but here's the end of rmaster.err. Back to you guys.

Loading /home/wes/rm/Linux-amd64/libjp12serial.so

[gfb107]

That's the error that lead to me to use g++ instead of gcc

BTW there should not be a space between -I and the directory name

Success. Should have tried g++ earlier. That did it. Space didn't seem to matter. Here's the compile line.

g++ -I /home/wes/jp12 -shared -fPIC -o libjp12serial.so jp12serial.cpp

I did a download and upload to my remote and it still worked so I'm assuming it's good to go. Should I upload it to the file section? Don't know why not, so here it is. Maybe some other 64bit uses can test it too.
