Error when building Saxon/C for PHP

Question

When I try and build Saxon/C for PHP under Ubuntu 16.04 I am getting a bunch of after running the make command.

This is the first error:

/bin/bash /usr/lib/Saxonica/Saxon-HEC/Saxon.C.API/libtool --mode=compile g++  -I

php_saxon.cpp:3297:40: error: ‘xdmAtomicValue_create_handler’ was not declared in this scope
 xdmAtomicValue_ce->create_object = xdmAtomicValue_create_handler;

The above error messages is the last one of many.

The first make was stopped when the compiler didn't find the jni.h file. I copied the header-file into the folder (that might be wrong?)

Error message:

Saxon.C.API/SaxonProcessor.h:10:17: fatal error: jni.h: No such file or directory

Second attempt stopped when the compiler didn't find the jni_md.h - again I copied the file to the folder.

php_saxon.cpp:5:
./jni.h:45:20: fatal error: jni_md.h: No such file or directory

Any directions on how to build this are welcome. I bet it is my lack of knowledge and not the fantastic software.

I am following the directions on this page: http://www.saxonica.com/saxon-c/doc/html/index.html and I have also tried using the phpize5.6 and phpize7.0

As mentioned by John. Adding the location of the jni should solve your problem. The troubleshooting guide should help you here. See: http://www.saxonica.com/saxon-c/index.xml#troubleshooting You have a few options here:

1) Edit the Makefile to include the jdkdir i.e.: -I$jdkdir/include -I$jdkdir/include/linux

2) Simply install gcj-jdk I have found to solve this problem

3) Copying the files jni.h and the jni_md.h files to the directory of Saxon/C code I have also found to work.
