Hi,

To reproduce: guix build htmlcxx — it blocks several dependents.

The relevant part of the error:

In file included from CharsetConverter.cc:5:
CharsetConverter.h:20:90: error: ISO C++17 does not allow dynamic exception specifications
   20 |                         CharsetConverter(const std::string &from, const std::string &to) throw (Exception);

These were deprecated in C++11 and removed in C++17: https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0003r5.html

So this may just need compiler parameters to set C++11 instead of C++17
as target.

A first step towards the fix might be

Looking at the README file from <https://sourceforge.net/p/htmlcxx/code/ci/master/tree/>,
it looks to me that upstream has moved to <https://github.com/bonitao/htmlcxx>. (judging by the name of the repo owner)
Can you try asking upstream for a new release? The last commit (<https://github.com/bonitao/htmlcxx/commit/0ffa3e90b7dc3944f199fd80ab47c2a82589209a>)
has the message 'Fix c+11 compilation'.


Cheers,
Bruno

I tried to build from the latest commit, but it did not build.

But I could now test adding the std argument and that works.

$ ./pre-inst-env guix build htmlcxx
/gnu/store/3bqrqs2zzx1gy4xc1g9i59z8nnhwv2rs-htmlcxx-0.87

A patch is attached.

I didn't see any dependant packages. Patch pushed! Thanks.
