cadabra2 on Debian sid got some problem #262

Closed alexmyczko closed 1 year ago

alexmyczko commented 1 year ago

but it used to build some time ago, so I'm really not sure where/how this problem arised. Here's the relevant link:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019333

If you have an idea, I'd be glad to hear about it...

If you remove the one spurious include of pcrecpp.h from core/Storage.cc (it's no longer needed) then you can drop dependence on pcre altogether. That should do the trick.

kpeeters commented 1 year ago

The reason for the problem is that Debian removed the old pcre library which Cadabra used to rely on. I switched to using regular expressions from the standard library or boost some time ago, but forgot to check for any leftovers.

Sorry, there is still some pcre dependence in TeXEngine.cc, let me fix that first.

2.4.0.2 on github now contains no more references to pcre.
