ok, so it seems that the reason is the file ~/.synopsis/parsers/cpp/emulator.
I deleted it, and now I also get your error ;)
Background: this file is generated (*if it does not exist yet*) by
/usr/share/pycentral/synopsis/site-packages/Synopsis/Parsers/Cpp/Emulator.py
which calls an installed gcc compiler to find the necessary builtin compiler
#defines (which are usually necessary to compile any code) and the
include file paths. The result is then stored in the above mentioned file
(I still had the contents of an older gcc version in this file, until I
removed it - thats the reason why I could not reproduce the error at first).
Then, ucpp (the C/C++ precompiler provided by synopsis) can use these
#defines and include file paths to preprocess C/C++ files.
As a workaround, you can simply edit ~/.synopsis/parsers/cpp/emulator
and remove the __STDC__ entry of the "macros" array:
macros=[('__STDC__', '1'), ('__STDC_HOSTED__', '1'), ...
will become
macros=[('__STDC_HOSTED__', '1'), ...
Then the error disappears. Still, you also need to pass a formatter
on the command line which creates the actual documentation output.
To create HTML documentation, use something like
synopsis -p Cxx -f HTML -o html *.cpp
This creates the html documentation in the subdirectory "html".
I will forward the issue to upstream.
Best Regards,
Andreas
