Saxon » SaxonC

Hi Lars,

It looks like you have an old version of Saxon/C. The python extension was added in the Saxon/C 1.2 series release and is available for all the Saxon products (i.e. HE, PE and EE).

See the download page for the latest Saxon/C release: https://www.saxonica.com/download/c.xml

Hey O'Neil Delpratt,

thank you for your quick reply. Good to know that there is a chance to get it working. Unfortunately I could'nt get back to this earlier.

I downloaded the latest linux64 binary just yesterday. I only wanted to make sure that the preceeding version did not contain the extension while the docs were outdated or alike. I will delete v1.0.2 now.

My issues arose solely with this latest version. I installed it as advised, but chose $HOME for installation location as my machine is a single user device.

Basically, I have two issues to solve:

1. the build64-linux.sh script struggles to find jni.h and aborts the compilation of test samples with 10-12 errors like

   ../../Saxon.C.API/SaxonCGlue.h:11:10: fatal error: jni.h: Datei oder Verzeichnis nicht gefunden
   #include <jni.h>
   ^~~~~~~
   compilation terminated.
   In file included from ../../Saxon.C.API/SaxonProcessor.h:32:0, from ../../Saxon.C.API/XdmValue.h:13, from ../../Saxon.C.API/XdmItem.h:11, from ../../Saxon.C.API/XdmItem.cpp:3:
   ../../Saxon.C.API/SaxonCGlue.h:11:10: fatal error: jni.h: Datei oder Verzeichnis nicht gefunden

   … and a bunch of these (~25):

   g++: error: bin/SaxonCGlue.o: Datei oder Verzeichnis nicht gefunden

   I tried:

   • softlinking included jni.h and companion file to $PATH locations, to .../Saxonica/Saxon-HEC1.1.2/Saxon.C.API, $HOME/.local/bin/ and other places
   • checked its execution rights
   • export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/ after I installed openjdk-11-source as an alternative source for jni
   • export JAVA_INCLUDE_DIR=/usr/lib/jvm/java-11-openjdk-amd64/include/
   • exported:

CPLUS_INCLUDE_PATH=/usr/lib/rt/amd64:$JAVA_HOME/include/linux:$JAVA_HOME/include CPLUS_INCLUDE_PATH=$HOME.local/bin/rt/amd64:$JAVA_HOME/include/linux:$JAVA_HOME/include CPLUS_INCLUDE_PATH=$HOME.local/bin/rt/amd64:$JAVA_HOME/include/linux:$JAVA_HOME/include:$HOMEDevelopment/Saxonica/Saxon-HEC1.1.2/Saxon.C.API/jni/ and what not

During all this fiddling, the amount of error messages decreased to the remaining:

In file included from ../../Saxon.C.API/SaxonCGlue.c:1:0:
../../Saxon.C.API/SaxonCGlue.h:11:10: fatal error: jni.h: Datei oder Verzeichnis nicht gefunden
#include <jni.h>
^~~~~~~
compilation terminated.

#include <jni.h>
^~~~~~~
compilation terminated.
g++: error: bin/SaxonCGlue.o: Datei oder Verzeichnis nicht gefunden

I don't know how good your German is but "Datei oder Verzeichnis nicht gefunden" translates to "file or directory not found" - you might have guessed it ;-)

2. There is no trace of a python-saxon directory in Saxon.C.API as mentioned in the respective documentation or anywhere in the installation path.

Any suggestions or help is very much appreciated. Thank you!

With Saxon/C 1.1.2 you can easily run into these issue. In this release you have to set the path to jni header files.

However in Saxon/C 1.2 you won't run into these issues as we now supply the jni header files with the product. Referencing is done locally in the C++ files so that you don't have to set it via the class path.

How embarrassing - I repeatedly read 1.1.2 instead of 1.2.1 in your answers and in the link you provided yesterday.

My apologies! I'll try 1.2.1 now. Thanks

Ok, it worked out better this time. A few warnings were thrown, but I suppose it is nothing critical:

• running the sample build script:

../../Saxon.C.API/XdmValue.cpp: In constructor ‘XdmValue::XdmValue(jobject, bool)’: ../../Saxon.C.API/XdmValue.cpp:74:38: warning: unused parameter ‘arr’ [-Wunused-parameter] XdmValue::XdmValue(jobject val, bool arr){ ^~~ testXSLT30.cpp: In function ‘void exampleSimple_xmark(Xslt30Processor*, sResultCount*)’: testXSLT30.cpp:674:64: warning: unused parameter ‘sresult’ [-Wunused-parameter] void exampleSimple_xmark(Xslt30Processor proc, sResultCount sresult){ ^~~~~~~ testXSLT30.cpp: In function ‘void testResolveUri(SaxonProcessor, Xslt30Processor, sResultCount*)’: testXSLT30.cpp:808:38: warning: unused parameter ‘proc’ [-Wunused-parameter] void testResolveUri(SaxonProcessor * proc, Xslt30Processor * trans, sResultCount * sresult) { ^~~~ testXSLT30.cpp: In function ‘void testPipeline(SaxonProcessor*, sResultCount*)’: testXSLT30.cpp:920:57: warning: unused parameter ‘sresult’ [-Wunused-parameter] void testPipeline(SaxonProcessor * proc, sResultCount * sresult){ ^~~~~~~ testXPath.cpp: In function ‘void testXPathOnFile(SaxonProcessor*, XPathProcessor*)’: testXPath.cpp:117:39: warning: unused parameter ‘processor’ [-Wunused-parameter] void testXPathOnFile(SaxonProcessor * processor, XPathProcessor * xpath){ ^~~~~~~~~

• the ./buildhec-command.sh for commands

Transform.c: In function ‘checkForException’: Transform.c:234:2: warning: format not a string literal and no format arguments [-Wformat-security] printf(utfName); ^~~~~~ Query.c: In function ‘checkForException’: Query.c:232:2: warning: format not a string literal and no format arguments [-Wformat-security] printf(utfName); ^~~~~~

• and I found something supposedly unwanted in the script ./testXSLT in cpp

Test: XsltProcessor with Saxon version=Saxon/C 1.2.1 running with Saxon-HE 9.9.1.5C from Saxonica

Error I/O error reported by XML parser processing /home/ond1/work/svn/latest9.9-saxonc/samples/php/catalog-test/test1.xsl: Datei oder Verzeichnis nicht gefunden …

Thanks for the guide! I propose we close this issue.

Great that you got it working. It looks like you are running the C++ samples. For python I suggest you follow the instructions given here: Installing Saxon/C Python extension
