Thank you.

Probably because there is no 'gen' directory in the current directory.

I did some web searches and this error appears to be caused by linker
running out of memory. This thread has some suggestions:

In particular, increasing the amount of RAM (either by installing more
or by closing some applications) seems to work.

I tried to compile your schema on my Linux box. Here is what I did:

1. Copy wxxm schema to the gml-3.2.1-split-code so that we have
   wxxm/wx/*.xsd and wxxm/avwx/*.xsd.

2. Create wxxm/wx and wxxm/avwx directories in the gen directory.

3. Create wxxm.options file in gml-3.2.1-split-code with the
   following content:

--polymorphic-type-all
--location-map http://schemas.opengis.net/gml/3.2.1/gml.xsd=../../gml/3.2.1/gml.xsd
--include-regex %../../gml/3.2.1/(.+)%../../gml/$1%
--namespace-map http://www.opengis.net/gml/3.2=gml32
--namespace-map http://www.eurocontrol.int/wx/1.1=wx11
--namespace-map http://www.eurocontrol.int/avwx/1.1=avwx11
--extern-xml-schema xml-schema.xsd

4. cd to wxxm/wx directory and run the XSD compiler like this:

xsd cxx-tree --options-file ../../common.options --options-file ../../wxxm.options --output-dir ../../gen/wxxm/wx units.xsd

5. cd to the gen/wxxm/wx directory (there we should have units.?xx files)
   and run the C++ compiler like this:

g++ -I../.. -c units.cxx

I also tried to compile other schema files in wx and avwx, but they seem
to depend on yet other schemas.
