2012/10/4 José Matos <jamatos(a)fc.up.pt&gt;: :-) I just updated the f17 repository to provide sagemath 5.4.beta1 There is also an updated numpy package with the patches from https://github.com/numpy/numpy/issues/291 For rawhide there is not yet a proper repository, but besides also providing a pre built numpy (that should not be required soon, as the patches are in the main numpy branch), I also added fplll patches, that I also posted at http://trac.sagemath.org/sage_trac/ticket/12835 One issue that was working flawlessly previously was the jmol interface, that now is not fully functional, I got it to work by using the JmolData.jar in the jmol tarball, but that is cheating as it would use a prebuilt jar. I almost got it to work by patching like this: ---%<--- diff -up sage-5.4.beta1/spkg/build/sage-5.4.beta1/sage/interfaces/jmoldata.py.orig sage-5.4.beta1/spkg/build/sage-5.4.beta1/sage/interfaces/jmoldata.py --- sage-5.4.beta1/spkg/build/sage-5.4.beta1/sage/interfaces/jmoldata.py.orig 2012-10-20 13:09:00.932379141 -0300 +++ sage-5.4.beta1/spkg/build/sage-5.4.beta1/sage/interfaces/jmoldata.py 2012-10-20 16:39:46.791863395 -0300 @@ -86,7 +86,7 @@ class JmolData(SageObject): sage_makedirs(jmolscratch) scratchout = os.path.join(jmolscratch,"jmolout.txt") jout=open(scratchout,'w') - testjavapath = os.path.join(SAGE_LOCAL, "share", "jmol", "testjava.sh") + testjavapath = os.path.join(SAGE_LOCAL, "bin", "testjava.sh") result = subprocess.call([testjavapath],stdout=jout) jout.close() if (result == 0): @@ -185,7 +185,7 @@ class JmolData(SageObject): scratchout = os.path.join(jmolscratch,"jmolout.txt") jout=open(scratchout,'w') #now call the java application and write the file. - result = subprocess.call(["java","-Xmx512m","-Djava.awt.headless=true","-jar",jmolpath,"-iox","-g",sizeStr,"-J",launchscript,"-j",imagescript],stdout=jout) + result = subprocess.call(["java","-Xmx512m","-Djava.awt.headless=true","-classpath","/usr/share/java/Jmol.jar:/usr/share/java/vecmath.jar:/usr/share/java/apache-commons-cli.jar","org.openscience.jmol.app.JmolData","-iox","-g",sizeStr,"-J",launchscript,"-j",imagescript],stdout=jout) jout.close() else: errStr = "Java Virtual Machine not available.\n" ---%<--- but it was failing with a null pointer exception when loading the interface to export a png image, and I could not get enough backtrace information to try to figure out what jar file was missing, and preventing it from generating a "quick" thumbnail of the plot... It would also require rebuilding jmol anyway, to either build JmolData.java and add JmolData.class to Jmol.jar, or install JmolUnsignedF.jar as JmolData.jar. So, for now the jmol interface wil show a harmless error message (due to not installing testjava.sh actually), and have a button to start an interactive plot. The new "advanced controls" work. Paulo
