Comment 4 Peter Levine 2016-09-23 22:31:35 UTC
IMHO these bugs aren't worth fixing.  There are a tremendous number of bugs based on the treatment of methods like std::complex<float>::real() as if they return an lvalue.  AFAIK they always returned an rvalue. i.e., 

> std::complex<float> tst();
> tst.real() = 6;  // Assignment to a temporary rvalue is meaningless

There are newer versions such as gnucap-2013-04-23 that should be bumped instead.

Comment 6 maurerpe 2017-06-23 02:19:23 UTC
This issue occurred starting with gcc 6.2 and still exists with gcc 6.3.  Starting with gcc 6.2 the default language standard for g++ is no longer gnu++98.  The code in question is somehow correct for c++98 with gnu extensions.  Adding -std=gnu++98 to CXXFLAGS fixes the issue.

As for the 2013-04-23 version, it has the same issue.  The models still require -std=gnu++98 to build and generate very similar errors.

Fixed ebuild for 20091207

This ebuild forces the CXXFLAG -std=gnu++98 which fixes the issue.

Bumped ebuild for 20130423

This ebuild works with version 20130423 it forces the CXXFLAG -std=gnu++98 and includes some other changes to build and install properly.
Comment 9 maurerpe 2017-06-23 02:30:31 UTC
For the record, I did try to build 20160724 as suggested by Bug 614656.  I had no trouble with the base code.  However, I could not build the models in the same repository:
https://git.savannah.gnu.org/cgit/gnucap/gnucap-models.git/snapshot/gnucap-models-af119e0688b6c984103aca6ab544f246a5e6723b.tar.gz
See Bug 614656 for details.

Working with gnucap-0.35.20091207, I was able to patch out the problems associated with modifying rvalues.  The C++11 standard explicitly sets aside the use of 'reinterpret_cast<T(&)[2]>(z)[0]' for `complex<T>` just for this very purpose.  There were more errors associated with the redefinition of 'bool'.  C++98 appears to have allowed redefinition of 'bool' but it is disallowed in C++11.  The work necessary to omit such redefinitions and adjust every point of use for 'bool' to some other equivalent pre-C++11 meaning would be quite large.

Normally I would caution restraint in using -std=gnu++98, as it acts as a bandage that might be more of a problem in the future if these issues are ever fixed upstream, this is a pretty good candidate for it.  Gnucap's models are full of code that depend on quirks in C++98 that have been ironed out in modern C++.  I don't use gnucap so I'm not sure how important the model plugins are (other distros like Debian and SUSE don't appear to install them).  If they are still needed, gnucap should probably force '-std=gnu++98'.  Otherwise, there shouldn't be a problem building gnucap without them.
Comment 11 Pacho Ramos gentoo-dev 2017-08-04 09:26:02 UTC
Then, I guess the only "solution" would be to try to bump to the latest one and drop models, right?

You could keep the current versions and just drop models.  IIRC it was the models that had the problematic code.
Comment 13 Oleg Korsak 2017-09-10 22:27:35 UTC
not sure if it is the same problem but I'm unable to build this package with 
gcc version 6.4.0 (Gentoo 6.4.0 p1.0)

    sci-electronics/gnucap: Force -std=gnu++98 to fix build with gcc-6, bug 594184
    
    The code is otherwise rather unfixable. Maybe one day somebody will have mercy
    and do a version bump.
