get exceptions with running run-summarizer.sh

[catherine667]

Hi,

I am trying to use your summarizer and refer your paper in my paper, but I got an exception as the following:

I am using mac os. I am trying to set java jni but I always got an error. There will be /usr/local/lib/jni in mac os wrote in the readme, but I can't find any folder with jni in my mac. Could you please tell me how to set jni with mac? I appreciate your help. Thank you.

(putting this here as well for others who have this issue)

I'm not sure what the exact issue is. I assume you followed the directions on http://glpk-java.sourceforge.net/index.html#Downloading for downloading and installing. I think I used brew (brew install glpk) for it.

You may need to add both /usr/local/lib/jni and /usr/lib/jni the path; that seems to be indicated on that download page.

This listserv post may also help (the error is similar): https://lists.gnu.org/archive/html/help-glpk/2010-04/msg00030.html

Finally, it's also possible that the glpk jar I distribute with the project is somehow outdated -- you might try replacing it with an updated one.

run-summarizer.sh runs a very small test that tests loading the JNI bindings (line 7, just below "# Extracts the existing java library path"). Running just that small java command may provide a faster way to debug.

Hope this helps, sorry I don't know what the issue is!

Hi, Thank you so much for your reply! May I know the computer system version you have used for this summarizer? I can try to find the same one to try your system.

Besides, I am really interested in how fast is your summarizer after training? I would appreciate if you can tell me the scale of the running time. Thank you.

Best,

@catherine667 were you able to solve this issue ? I am getting the similar error.

[catherine667]

@skrealworld It seems like it was the version of system problem. I haven't solved it yet.

I have tried this on OSX 10.2 and Ubuntu 14.04, still giving me the same issue. In both cases I can't see "libglpk_java" file. I tried to install from the source also but it throwing this error : checking for mvn... /usr/local/bin/mvn checking whether to load GLPK library from java.library.path... no checking for thread local storage (TLS) class... _Thread_local checking glpk.h usability... no checking glpk.h presence... no checking for glpk.h... no configure: error: glpk.h not found

I can find this "glpk.h" at /usr/local/include.

Any help will be appreciated.

Hi all,

I had the same problem on OSX 10.12.4 and I installed libglpk_java from sources by running configure -> make -> make install. During compilation I had to export:

CPPFLAGS="-I /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home/include/ -I /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home/include/darwin/".

Then run-summarizer.sh runs without errors.

Best, Panayiotis

I think that the source of the confusion is that berkeley-doc-summarizer/lib/glpk-java-1.1.0.jar (i.e. the one committed to the repo) is useless, because it doesn't include its native library. It's not just the glpk package that is native code, libglpk-java has a native library too.

For macOS, you can use brew install glpk, and then compile libglpk-java from source (following the comment from @psmeros).

I saw a comment elsewhere that you need brew install swig too (I already had that so I'm not sure).

I ended up with:

• macOS High Sierra
• /usr/local/lib/libglpk.dylib (from brew)
• /usr/local/lib/jni/libglpk_java.dylib (from libglpk-java's make install)
• /usr/local/share/java/glpk-java.jar (from libglpk-java's make install)

./run-glpk-test.sh runs fine after that.
