Description

Installation of libsaxon-HEC-setup64-v1.0.2 on Centos 6.8. When xpathExamples.php is executed from the browser it fails. httpd error log shows the following:

"Error: : No such file or directory

Unable to load /usr/lib64/libsaxonhec."

Notice the "so" is missing from the filename extension.

libsaxonhec.so file does in fact exist under both /usr/lib and /usr/lib64 +copied as per instructions+. It however now requires both /usr/lib64/libsaxonhec. and /usr/lib/libsaxonhec. to exist in order for php to find them and execute the script.

During installation ldconfig output errors with libsaxonhec.so is truncated, which devs say previously to ignore.

Output from phpinfo correctly shows

Saxon/C enabled

Saxon/C EXT version 1.0.2

Saxon 9.6.0.9

chcon was properly updated as per instructions for this library.

Thanks for reporting it. O'Neil is on vacation this week but I will leave it for him to look at when he's back, since he's the expert in this area.

Hi,

Thanks for reporting the problem you have found. I will investigate this and try to reproduce the problem you have found on a centos machine and report back shortly. There has been some changes in this area of locating the library so it could be possibly a bug.

As a workaround you could try and set the environment variable SAXONC_HOME to where the libsaxonhec.so is located on your machine.

Well it was working with my work around but now most of the time it just crashes with JET errors similar to this once resolved bug.

https://saxonica.plan.io/issues/2670

Security context however is correct

chcon system_u:object_r:lib_t:s0 /usr/lib/libsaxonhec.so

chcon system_u:object_r:lib_t:s0 /usr/lib64/php/modules/saxon.so

JET RUNTIME HAS DETECTED UNRECOVERABLE ERROR: system exception at 0x00007ff2ba05aee9

Please, contact the vendor of the application.

Extra information about error is saved in the "/tmp/jet_err_12144.txt" file

Attached: jet_err_12144.txt"

Just to add, I am using php 5.6 and openjdk-1.8.0.

There is a bug in the SaxonCGlue.c file. where it locates the library it has incorrect length of the directory string. I have committed a fix to this under subversion. As mentioned in comment #2 you can use the SAXONC_HOME environment variable to avoid this problem.

I am looking at your comment #3 to try and reproduce the error you are getting.
