It isn't possible to compile, because the `elm.xml` file has multiple issues :( The script "data/schema/validatehl.sh" serves to verify the XML files: cd syntax-highlighting/data/schema/ ./validatehl.sh ../syntax/elm.xml Output: ../syntax/elm.xml:3: element language: Schemas validity error : Element 'language', attribute 'version': '1.0' is not a valid value of the atomic type 'xs:integer'. ../syntax/elm.xml:43: element WordDetect: Schemas validity error : Element 'WordDetect', attribute 'string': The attribute 'string' is not allowed. ../syntax/elm.xml:43: element WordDetect: Schemas validity error : Element 'WordDetect': The attribute 'String' is required but missing. ../syntax/elm.xml:84: element StringDetect: Schemas validity error : Element 'StringDetect', attribute 'char': The attribute 'char' is not allowed. ../syntax/elm.xml:84: element StringDetect: Schemas validity error : Element 'StringDetect': The attribute 'String' is required but missing. ../syntax/elm.xml:86: element context: Schemas validity error : Element 'context': The attribute 'lineEndContext' is required but missing. ../syntax/elm.xml:93: element context: Schemas validity error : Element 'context': The attribute 'lineEndContext' is required but missing. ../syntax/elm.xml:102: element context: Schemas validity error : Element 'context': The attribute 'lineEndContext' is required but missing. ../syntax/elm.xml:114: element itemDatas: Schemas validity error : Element 'itemDatas': This element is not expected. Expected is ( context ). ../syntax/elm.xml:4: element highlighting: Schemas validity error : Element 'highlighting': Missing child element(s). Expected is ( itemDatas ). ../syntax/elm.xml fails to validate For example: `</contexts>` (line 133) must be placed before `<itemDatas>` and `dsHexVal` isn't a valid default style (use `dsBaseN`, look here <https://docs.kde.org/stable5/en/applications/katepart/highlight.html#kate-highlight-default-styles>). By solving it, maybe compile everything well. Also, I'm not sure if Elm should be in the "Sources" or "Script" section (maybe not so relevant). To compile, try installing: libkf5syntaxhighlighting-dev qtbase5-dev libqt5xmlpatterns5-dev perl (although installing the first installs the rest) REPOSITORY R216 Syntax Highlighting REVISION DETAIL https://phabricator.kde.org/D19438 To: bonghyunkim Cc: nibags, dhaumann, kwrite-devel, kde-frameworks-devel, gennad, domson, michaelh, ngraham, bruns, demsking, cullmann, sars
