Apache module using Xalan
Since nobody seems to be able to give me an answer I put togheter some code
which I compiled with gcc -o xala_test xalan_test.c -lxalan-c1_3, and it
worked. I used both XalanTransformToHandler and XalanTransformToFile, and it
all worked.
So I took the same code and put it together as an apachemodule (I based it on
the code coming out of apxs -g -n foo), and it started causing Apache to
segfault. I tried to hard code the filenames, using files in a directory which
was chmodded 777, in case some trouble with privileges was the problem, but
that didn't help.
I clearly was misstaking when I thought that Xalan being an Apache product
would work good together with the httpd.
I still haven't got the ApacheModuleXSLT in samples/ to work, either.
It is of great importance to me that I produce a working set up with Apache
handling the XML transformation, and not as a CGI. Could anyone at least try to
help me, please?

Re: Apache module using Xalan
Posted by Nouguier Olivier <ol...@wanadoo.fr>.
hi all,
I'm really not an expert in c or xalan, but I had segfault when I
compile my module and apache were compiled with different version of gcc
( 2 vs 3 ).
Hope it helps

My mother always used to tell me, "The early bird gets the worm."
The message seemed pretty clear to me: If you sleep late, you're
a lot less likely to be killed by a bird.
