Re: [ooc-compiler] make error after libxml2 update on FC1

[Stewart G. <sgr...@ii...>]

Hi,

I've also had this problem under FC1. It seems to ship with a broken  
xsltproc. At least, for some files generated by OOC xsltproc will  
segfault. I think the bug is in libxml. You can verify this using gdb  
(see below). I was unable to fix this problem, even after reinstalling  
the libraries from source.

One workaround is to disable xsltproc. From memory, you can do this by  
setting:
   XSLTPROC=no
before you run configure.

Actually, I think this issue needs a statement in the installation  
documentation. Without an XSLT processor, oo2c will not generate  
documentation for the included modules. If the XSLT processor is there  
but is broken, it needs to be disabled before oo2c will build.

Cheers,
   Stewart
