[xsd-users] Error: incomplete type when compiling cxx generated with --file-per-type

[Yongchang Huang]

Hi Boris,

I can build xsd tool from the new released and tried to generate cxx files,
and it seems the generated .cxx can compile now.

Then I tried to build libxsd library in order to test the generated .cxx
files, but I have trouble building libxsd with the new version using build2
tool.

*bpkg build libxsd* command reported below error:

fetched libxsd/4.2.0-b.4
unpacked libxsd/4.2.0-b.4
configured libxsd/4.2.0-b.4
version libxsd-4.2.0-b.4/xsd/cxx/in{version} ->

  info: while updating dir{libxsd-4.2.0-b.4/}
info: failed to update dir{libxsd-4.2.0-b.4/}

buildfile is hard to understand compared to Makefile, and I tried to
understand how buildfile works, and tried to remove doc target
in libxsd-4.2.0-b.4/buildfile as shown below:

./: {*/ -build/} doc{INSTALL NEWS README} legal{GPLv2 LICENSE FLOSSE}
manifest

to

./: {*/ -build/ -doc/} legal{GPLv2 LICENSE FLOSSE} manifest


but libxsd so file was not generated somehow. It seems the
libxsd-4.2.0-b.4/xsd/buildfile was not used.

thanks,
yohuang
