Trying to compile pdftk with gcc6:

And 50 more above that.
I have gjar and gcj but they seem to be associated with gcc-5.4.0.

gcc6 has a gcj flag but I am unable to apply it for some reason.
Much obliged to anyone who can point me in the right direction. |

imesg,
The (-gcj) means that the flag is forced off in your profile.
I have built gcc-6.3 with gcj but its not well tested. The java compiler is being removed in gcc-7.
Make the file /etc/portage/profile/package.use.mask/gcj
Add a line | Code: | | >sys-devel/gcc-6 -gcj |
to invert the setting inherited from the profile, for versions of gcc above 6
This will remove the ().
Enable the gcj USE flag in the normal way.

How likely is this -gcj unmask to cause trouble for compiling packages? pdftk seems to require it. If one removes the gcj use flag globally and only enables it on pdftk in package.use, would it then affect any package except pdftk?
E.g. is there a risk a package not using gcj use flag fails to compile if gcj is enabled for gcc and pdftk alone? |

You should keep gcc5 for package that require gcj (see here and here)

| It seems qpdf might be a partial alternative to pdftk that is still developed. Does anyone have any experience with it? How do they compare? |

As I noted in another thread, a few years ago when I needed to do some mangling of PDF's I worked with both PDFtk and QPDF. My recollection is that I could do more of what I wanted to do with QPDF. I'm glad to see that that's the one still under development.
That said, I note that current version of QPDF is 7.0.0. The stable version of app-text/qpdf is still at 5.1.1-r1. QPDF 5.1.1 is pretty long in the tooth. Version 7.0.0 is in the tree (as are two intermediate versions) but keyworded. The package was still at 5.1.1 when I compared it to PDFtk. |

And 7.0.0 fixes several security issues; so best move to that version. |

I'll look more into using qpdf. It seems to be able to do most stuff that pdftk can do.
Though the usage and documentation appears to be more complicated / less complete. Anyone know a good frontend for qpdf? |

Is there any reason why it is not possible (after making the required changes in portage configuration files and in the pdftk ebuild) to compile it with gcj from gcc6? |

See this comment. |
That comment and everything else I've read on this matter so far seems to imply that it is possible to have and use gcj from gcc-6.*. The USE flag is masked, but you can unmask it. If you check the comment for that mask, it looks like there's absolutely no problem in building gcc-6.* with gcj and that it was an attempt to use the mask as a news item.
The reason why I am asking is to know if there is actually some problem with gcj from gcc-6.*, or if it would be okay to simply unmask the USE flag and adapt the pdftk ebuild to use that version of gcc. |

I think if you unmask this use flag probably you can compile pdftk. The problem is with gcc-7 that remove java support.
| /usr/portage/profiles/base/package.use.mask: | # Magnus Granberg <zorry@gentoo.org> (18 Jan 2017)
# Adding the mask so that end users and devlopers are notified of the removal and have some
# time to migrate. There is no support for gcj in gcc-7
>=sys-devel/gcc-6.3.0 gcj |

Okay, so I enabled USE=gcj for gcc-6.4.0, adapted the pdftk ebuild and managed to compile it with this version of gcc after removing 5.4.0 from my system.
So far, it seems to be working. |
