no newline at end of file

[habdank@…]

Dears,

Some Boost packages causes flood of warnings "no newline at end of file" on gcc compiler.

As example:

I can't reproduce this. I looked at the files you mention but I don't see any missing newlines at the end. I looked at the files in both Linux, Mac and Windows. My guess is that you've got a problem when obtaining the source? I'm not sure.

Please investigate further. The problem does is not in Boost, as far as I can tell.

Hi, I have the exact same problem.

boost/fusion/tuple/detail/preprocessed/tuple.hpp:21:7: warning: no newline at end of file

I got the source (boost_1_53_0.tar.bz2) from sourceforge. Built an installed standard (./bootstrap.sh --prefx=/my/pfix ; ./b2 install).

I checked the file and it seems to be autogenerated, and really, the last character on the file is the "f" from #endif. Here's the file

Confirmed. There must've been something wrong with the way the trunk got merged into release. Trunk is just fine. I'll make sure this gets merged correctly when I do the next merge to release.

Reopening, as this has still not been resolved. I just pulled down 1.55 (boost_1_55_0.tar.bz2) and built for OS X. Still no newline at end of file.

For reference here is my boost/fusion/tuple/detail/preprocessed/tuple.hpp:

Last character is "f", not newline.

And this is my build command, in case it matters:

./bootstrap.sh
./b2 -a toolset=clang cxxflags="-std=c++11" link=static variant=release address-model=64 architecture=x86 threading=multi runtime-link=static --without-math --without-graph --without-wave -sZLIB_SOURCE="../../../../zlib-1.2.7" --stagedir=./Mac106/build/Release stage

Where is this generated from, as this file appears to be in the tar file rather than being rebuilt.

I have no OS X machine but it seems already to be fixed. ​https://github.com/boostorg/fusion/commit/b6142f16133b21ee0c5e9c8ec48646f2654e74b4

Thanks a lot for fixing it.

EOL at the end of header file is very old requirement which comes from C, but I think it is also better for readability, when the code ends with new line.
