I'm trying to port some existing code that uses boost into native-client.
I compiled boost according to the instructions here: https://code.google.com/p/naclports/wiki/InstallingSDL (with boost instead of sdl), and tried injecting some boost code into one of the examples.
I was successfully able to use a boost::shared_ptr by editing examples/api/socket/socket.cc by including the header and adding a simple test method:
#include <boost/shared_ptr.hpp>
The test method:
void ExampleInstance::test_shared_ptr() {
boost::shared_ptr<std::string> test_ptr(new std::string("hi"));
PostMessage(test_ptr->c_str());
}
Invoking this method from the constructor results in a "hi" appearing on the console when loading the page you can reach by running "make serve".
Although I'm deeply impressed that this much works, my app uses boost::thread and boost::asio, and there I ran into trouble. In pepper_34, if I add:
#include <boost/threads.hpp>
I get these compilation errors, just by including that file:
~/nacl_sdk/pepper_34/examples/api/socket$ make

make: *** [newlib/Release/socket_x86_32.o] Error 1
(Side Note: I don't think the CHROME_PATH warning at the top is causing these errors, since I get the same warning for the examples even without my edits, but the examples still work. I imagine it's because I'm building on a vm without chrome installed (or a window manager in which to run it), since I had to use linux to build boost according to the error message the boost build process gave when I tried building it on OSX. The error messages suggest this interferes with "make run_package", but otherwise the examples run properly under "make serve", and can be tested from a different machine, using chrome to access the pages. I'm writing this question while waiting for chromium-browser to install, in hopes I can confirm that theory.)
In case it matters, I'm running Ubuntu 12.04.
My questions:
- Is there a previous pepper version in which somebody has successfully used boost::asio and/or boost::threads?
- Has anyone encountered this problem and discovered a workaround?
