Boost errors

[Praveen C]

Dear all

Using deal.II at edeb002dcc4bec713788c14, when I compile my application, I get boost errors which are attached. I am using bundled boost. deal.II compilation goes through, but my application does not compile.

Thanks

Praveen,

can you provide us with a minimal example showing the problem?

Since this problem doesn't appear when compiling the library, it is difficult to guess the cause.

Best,

Daniel

So it was an issue in my own code. I had these two lines

#define T0            0.80   // bottom wall temperature

#define T1            0.85   // top    wall temperature

and it looks like this conflicts with something in Boost. Renaming T0 and T1 to something else solved the problem.

Thanks

One of the many reasons why using preprocessor #defines is not a good idea.
Make these regular variables:
const double T0 = 0.8;
This would likely have worked.

Indeed,

One of the many reasons why using preprocessor #defines is not a good idea.
Make these regular variables:
   const double T0 = 0.8;
This would likely have worked.

or even better, make use of the dealii::ParameterHandler and corresponding input files,

iff you have the time for such an implementation...

Personally, I'll skipped this for a long time, currently I'm using it a lot. Its a good feeling

not to compile the application again for some input parameters. Its even better than to

overwrite preprocessor defines (which I also have done in the past).

Always be careful when including boost, at least in the past, they have put features into

the std namespace.
