Re: [Boost-users] [boost-users][proto] Using proto with nvcc

Joel,

The code I am trying is very simple :

#include namespace proto=boost::proto;

int main() { return 0; }

nvcc version is 3.0. I am trying on a 32-bit Linux (Fedora-10) platform.

Manjunath

Manjunath, I was able to compile your code without errors. I'm using Ubuntu linux2.6.28-16-generic x86_64 GNU/Linux + boost-trunk rev. 61489 + nvcc 3.0. Are you sure that you are compiling against the trunk version? Maybe the include path is pointing to the wrong boost version? Regards, Denis

I noticed that fix for ticket #3919 has been checked-in. Thanks JoelF. I checked out boost trunk, and am trying to compile the following simple program using nvcc. #include namespace proto=boost::proto;

int main() { return 0; }

I was getting "ISO C++ forbids declaration of ‘expr_param’ with no type" error in couple of places in proto/traits.hpp and proto/transform/pass_through.hpp. The code used to look like

typename pass_through_impl::expr_param e

I added a typedef as follows

transform_impl base_type;

and changed the code to

typename base_type::expr_param e

Now the compiler error goes away. I have 2 questions : 1) Is what I am doing the right fix for the problem, or is the nvcc compiler really broken when handling this? 2) If my fix is OK, how do I make it permanent?

The other error I am seeing is probably not proto's problem, but I will mention it here anyway :

boost/boost-trunk/boost/mpl/size_t_fwd.hpp:23: error: expected unqualified-id before ‘[’ token boost/boost-trunk/boost/mpl/size_t_fwd.hpp:26: error: ‘mpl_::size_t’ has not been declared boost/boost-trunk/boost/mpl/aux_/integral_wrapper.hpp:42: error: expected unqualified-id before ‘[’ token

Any ideas on this?

i'm still fiddlign with this fix. Any report will be appreciated. Can you make a small reproducable test case so i can test it. Also can you rpovide me with your nvcc version ?
