Re: [pygccxml-development] Parsing a single header file for the whole project

[Benoît L. <ben...@gm...>]

What I ended up doing is:
creating a temporary file with a list of #include "header_path" then
constructing the module_builder_t with this file.

I first tried with create_text_fc but if you do that, in all the cpp
files generated by py++ , you won't get any include, so nothing will
compile.
The only weird thing now is that in all the cpp files, they all
include this temp file, so I need to keep this temp file for building.
I didn't know this create_cached_source... I'll try that to see if
that solves my problem.

I remember I tried the cache=cache_file_path option to
module_builder_t constructor, but it was not helping at all.
Each time the cache file was read, then recreated, and the generation
time was almost the same as without any cache.
