Here you go:

https://github.com/NikolaKozina/j2534

Requires libusb. Just run (as root)

Code:

make && make install

To apply my RomRaider patch, run this in RomRaider/ directory:

Code:

patch -p0 src/main/java/com/romraider/io/connection/ConnectionManagerFactory.java < RomRaider-j2534-linux.patch 

Make sure you don't have an SD card in your Tactrix cable, since it changes the USB product ID.

Let me know if it works. I'll be in #romraider on freenode.

Finally had a chance to try this out. I'm been banging at it for like 20 minutes and I cant get past fatal error: libusb.h: no such file or directory. Even stack overflow is no help. Whats extra odd is that I literally navigated to the file path that your install file is referencing and the f*** file is right there, everything is named correctly. I did have to install libusb-1.0-0-dev to get it this far and didnt restart, not that that should matter. Yeah, I'm stuck.

What's the output of

Code:

pkg-config --cflags --libs libusb

Good/bad?

Bad. Mine says:

Code:

-I/usr/include/libusb-1.0 -lusb

Do you have the non-dev version of libusb installed?
Make this the second line in your makefile:

Code:

CFLAGS+='-I/usr/include/libusb-1.0 #or whatever the path is to libusb.h on your system

I made sure to install the dev version according to package manager I have both libusb-1.0-0-dev and libusb-dev installed. There was a passing mention of some problem that could be caused by having both installed for some reason on one of the post on stackoveflow for someone but their problem ended up just having only installed libusb-dev and not libusb-1.0-0-dev which put the header file in different locations.

Did the fix work? BTW, we probably should've started a new thread for this.

Leafy · **Posted:** Fri Mar 06, 2015 11:09 am

I'm at work. I'll try the fix when I get home.

Leafy · **Posted:** Fri Mar 06, 2015 6:44 pm

I believe it worked. Output of make && make install run as root was this.

Code:

gcc -g -shared j2534.o `pkg-config --cflags --libs libusb` '-I/usr/include/libusb-1.0' -o j2534.so
mkdir -p /usr/local/lib/
mkdir -p /usr/local/include/
cp j2534.h /usr/local/include/
cp j2534.pc /usr/lib/pkgconfig/
cp j2534.so /usr/local/lib//j2534.so

I'll test to see if the drivers worked with the cable in a couple hours.

Don't forget to apply the .patch to your RomRaider tree.

I'm hoping to not have to do that since I'll have to figure out how to patch the windows version. I couldnt get the linux version to install but the rest of the tuning software I use (hp tuners, aem tuner, etc) only have windows versions but their interfaces have functional linux drivers because they use standard serial to usb chips so they pass right through into my VM without me having to do any real thinking. And I hope to be able to say the same for ECU Flash since thats what really really needs to be able to talk to the tactrix cable for me on my laptop. Stuff like learning view working would also be a nice bonus.

You need to patch the Java source and recompile the Linux version so that the connection manager can locate and use your new library, otherwise the OP2 will not be recognized.

I tried this but Java is crashing when it attempts to use the new library. If I remove the library from the dir it defaults back to serial and works fine.

Various logs for your review.

I used this code as my patch.

Code:

            if (!isPlatform(WINDOWS)){
                final String j2534Lib = "/usr/local/lib/j2534.so";
                final File libFile = new File(j2534Lib);
                if (libFile.exists()) {
                    return J2534TransportFactory.getManager(
                            settings.getTransportProtocol().toUpperCase(),
                            connectionProperties,
                            j2534Lib);
                }
                else {
                    throw new RuntimeException("J2534 library not found in: " +
                            j2534Lib);
                }
            }

Crashes at line 584 'lib.PassThruOpen' of J2534Impl.java:

Code:

    public int open() {
        NativeLongByReference pDeviceID = new NativeLongByReference();
        NativeLong ret = lib.PassThruOpen(null, pDeviceID);

Try changing

Code:

#define LOGFILE "~/op.log"

in j2534.c to a file you can write to. I guess ~ doesn't expand in C. I had that hardcoded to my home directory and I changed it to ~ for release.

Why can't you just install the windows tactrix drivers inside your VM and then pass USB through? That's what I've been doing with VirtualBox.

That helped a bit but it's still not working...
