Hi, I would just like to make a quick report on my progress.
I made a shared object "libfilepicker.so" completely independent of
tntnet. I tested it with a standard console application and it works as
expected. It simply reads a JPG file from disk and returns it as a
string of bytes in a std::string (simulating generation of an image at
runtime).
The good news is that I am able to use "libfilepicker.so" from a tntnet
project ("stest1.so") and send a JPG image to the browser, as explained
by Tommi and Olaf earlier. It is a start.
What I don't quite understand is that if I use boost in my
"libfilepicker.so", then "stest1.so" fails to load in tntnet. This is a
problem since I need to use boost for several things.
Here is what I see when I simply #include a boost header in my C++ code
in "libfilepicker.so" (I don't even use any features). My tntnet
component fails to load:

Here is what I see when I don't #include boost headers, everything works.

Notice that the boost headers are not included in the ecpp code, just in
my independent "libfilepicker.so" which does not know about tntnet.
I don't quite understand this problem of loading the component *.so.
FYI, I have built boost 1.55.0 myself from source as follows
./bootsrap.h
./b2 link=static
Any ideas?
Otherwise, I feel encouraged to have achieved something, if not very
much. Since the website is down, it makes it harder, but I found a
tntnet.pdf with the installation that contains useful information.
Best regards
