[Discuss-gnuradio] adding XML support to OOT block

[Steven Knudsen]

Hi,

I would like to do something I think is not uncommon and that’s to add XML support to a block (e.g., to read a config file). 

Everything compiles, but on link all the libxml2 functions generate “undefined references”. I believe there is a missing -lxml2, but how and where to add?

Online search does not turn up much, and what there is seems to be from around 2008 when the build system was different.

I did try modifying the CMakeLists.txt for my module, but it appears that I don’t know how to augment or override the GR support for libxml2. That is, I can add find_package(LibXml2) and that works as expected, but modifying any of the env vars doesn’t seem to help.

Any advice would be much appreciated. I suspect there may be an example out there that I’ve just not found and I will be chagrined, but grateful to the person that kicks me that direction…

Thanks very much,

steven
