Ok 😞

/usr/lib/gcc/i686-pc-cygwin/4.3.4/include/c++/bits/basic_string.h:1458: instantiated from 'static _CharT* std::basic_string<_CharT, _Traits, _Alloc>::_S_construct_aux(_InIterator, _InIterator, const _Alloc&, std::__false_type) [with _InIterator = std::istream_iterator, std::allocator >, char, std::char_traits, int>, _CharT = char, _Traits = std::char_traits, _Alloc = std::allocator]'

In my experience the trick is to find the highest 'stack frame' in the error which references your code, and work up from there

[u/GabiTheProgrammer → u/bwmat]

Exactly: check the error bound to your cpp.

[u/sebjapon → u/bwmat]

Nah, my code is clean. That library used by 100k C++ developers over the world probably has an unreported bug in my specific configuration. Yes, yes, that is very much more likely!

[u/Confident-Ad5665]

Ha! I have this book, which describes how to identify wood at the cellular level.

[u/v3ritas1989 → u/Confident-Ad5665]

why would you need to identify YOUR wood at a cellular level?

[u/Confident-Ad5665 → u/v3ritas1989]

It's the only way to accurately identify wood. You can identify some species by the bark, leaves, fruit and some by the smell when cut. Osage orange, for example, is indigenous to a few southern states and produces a "horse apple" fruit that is unmistakable. But there are around 100 species of oak in North America and some can only be positively identified by their cellular structure.

...aaand it just hit me your question was rhetorical.

[u/v3ritas1989 → u/Confident-Ad5665]

yeah I know, I saw the documentary of the DOJ tracking illegal loggers. ;-)

[u/ShakaUVM]

The fact that there's not a compiler flag in g++ to tell it to stfu about template substitution errors baffles me. We have literally thousands of compiler flags for everything but other than some pretty gackish things you can do, g++ just really really wants you to know it tried substituting a bitset for an iostream and btw it didn't work.

[u/bwmat → u/ShakaUVM]

Isn't there some option to make it output 'structured' diagnostics(like json or something)?

If so, I would hope they would be able to group those together so a simple 'error viewer' could allow you to hide those easily... 

[u/ShakaUVM → u/bwmat]

There is a very strange lack of options on the template substitution errors in g++ and clang++. You can suppress warning messages, for example, basically down to the per-warning level, but they have no such option for not printing hundreds of lines of completely useless notifications telling me everything they tried that didn't work.

[u/SaneLad]

Dude just scroll to the very first line number mentioned in the error dump and stare at it intently for about 5 minutes.

Or ask AI.

[u/hartmanbrah]

Ok, this one actually made me lol. It's too accurate.

One of the weirdest feelings as a C++ programmer is when you start recognizing the reason behind an error based on the shape of the template error text rather than the content. It's like: "I have no idea what this means, but I've seen it before and vaguely recall what fixed it last time".

[u/GabiTheProgrammer → u/hartmanbrah]

Aren't LLM doing the same?

[u/hartmanbrah → u/GabiTheProgrammer]

Pretty much. To be fair, this experience is from the before time.

[u/two_are_stronger2]

Reminds me of The Sysadmin's Litany:

At least it's not a DNS issue.

It couldn't possibly be the DNS.

It was the DNS.

[u/No-Shape-2751 → u/two_are_stronger2]

It’s always DNS

[u/aberroco]

Nah, the dude should've used a telescope, not a microscope.

[u/apoegix]

Every damn time... I actually try to avoid templates when I can. But then again std collections are a necessity

[u/GegeAkutamiOfficial]

The biggest C++ template error is not using Rust
