gnu: emacs-consult: Fix grammar.

[jackhill/guix/guix.git] / gnu / packages / patches / gromacs-tinyxml2.patch

Unbundling tinyxml2 from gromacs and using our own, which is newer, broke gromacs
build.

This patch fixes three issues:

- cmake now errors out if using multiple target_link_libraries with mixed styles
  of signatures.

- Error handling API changed, fix the testutils/refdata_xml.cpp code by using the
  new API: document.ErrorStr() & tinyxml2::XML_SUCCESS.

Those fixes will be submitted for inclusion to upstream, but may not be suitable
there as long as they still keep the old version bundled.

First hunk has already been requested for merging. Third is in discussion. Second
will only be sent if third is OK'ed.
