Jeffrey of YOSPOS posted:I do mostly low-level stuff and what I want to see on a resume is experience in systems programming, with examples of projects worked on. From there I can often reason about what sort of thing the person was doing and follow up on it on a phone interview. A combination of being able to talk specifics about your prior projects and what you personally did, and pass (difficult) technical interviews will do it. Sometimes if a company is unsure that you know your stuff they'll have you take an online C++ test or something before bringing you in. Sure this makes sense for what to do during phone interviews, but I was actually asking about what comes before that point: specifically, what you put on that resume to actually get to that phone interview. Do you just put "C++" on your resume and then you hope that you don't get Black Hole'd so that you can actually talk to a human being about your experience with the language?

Talk about projects that you've done using C++ and you can say specifically "in C++" in the description if you'd like. I look for a cluster of related things including not only the language C++ but also low-level computer systems knowledge in general. If I were instead at a game company I might look for game programming projects instead. I don't know how it works at really big companies but our resume screeners read the project descriptions and aren't just looking for keywords.

C++17 (or whatever you know) rather than C++. Especially don't put C/C++ as a skill on your resume. Esp. if you're new to the industry, put your github on your resume with a project using some of the libraries I said before so you demonstrate that you can work with other people's code (they are way way better implemented than half the poo poo you will find in production but eh.) I'm not in charge of hiring but generally people get in because they could demonstrate C++ knowledge; C++ is a gigantic hell language so you're not expected to know all of it nor all of the third-party libraries. You're expected to know how to use it though and a personal project is a good demonstrator of that. e: also C++ might not be a good choice if you're trying to break into programming as a career regardless. The job market where I am for C++ is pretty dire. The Phlegmatist fucked around with this message at 15:35 on Dec 19, 2017 |

I guess it helps if you have previous jobs or stuff you can use, ie I have modern C++ as a skill for people who search for keywords, but my list of experience goes like - "Modernized university course to teach C++14 and then spent 2 years teaching" - "2 years of programming soft real time safety critical systems in C++" - "year of maintaing popular C++ OSS project" - "year of programming medical software in C++" ... not sure what else would you expect there? 2 years of using Boost?

My friend is doing Arduino dev using Embed XCode and a full C++ stack. Today he called me because he has a problem with the following code:  What happens is the following: when position_1.state == 1, it's like old_position never gets "stored". The output looks like this code:code:I did a global search for old_position and I can confirm this is the only place that this variable is called. Would it be possible that some kind of compiler optimisation is doing something weird? Or do I tell my friend to read his code one more time because there is absolutely 100% no way that this is some kind of compiler bug?

Initialize it to some value (0?, 1? whatever you think it should be) in the initializer's list or somewhere. The idea is that it should have a known value by the time the first position_1.state != old_position is being done.

I have a C++ question that isn't really a C++ question. I am building a library that is not generating a PDB file for release build. The library is called SFML. However, I need PDBs or some kind of information because I am trying to debug this crash that has only happened in release builds so far: code:I don't know how to make visual studio create a PDB file when I build this library. This really old article tells me it is in "linker" settings, but I don't have linker settings https://blogs.msdn.microsoft.com/yash/2007/10/12/pdb-files-what-are-they-and-how-to-generate-them/ Here's a question and article about how to generate a pdb for a release build, but I don't know what to do with the answers. https://www.wintellect.com/correctly-creating-native-c-release-build-pdbs/ https://stackoverflow.com/questions/28178978/how-to-generate-pdb-files-for-release-build-with-cmake-flags It seems like I need to do something with CMake in order to get CMake to create a Visual Studio solution that will create a pdb, but I don't really want to learn anything about CMake right now, or ever. I dunno you guys. What course do I take in these trying times?

Are you actually using CMake to generate the MSBuild project files for running the build? If not, you shouldn't need to involve another tool for it. When you open the Properties for the project in VS you should be able to set it up here:

I'm trying to make a wrapper around GLM's datatypes, so I can easily implement conversions to/from various different libraries' vector types, and replace it easily with my own implementation if I want. Is there a way to extend them without having to specify my own operator overloads? I have C++ code:code:

You could write an implicit conversion from the glm vectors to your vector type. But if you're looking to do things like "multiply two vectors from different libraries", you're probably going to have to write that one yourself.

No, I want a vector type that I use for everything that has conversions to/from all other vector types, so I only use that one in my own stuff, then do conversions when I want to interact with a library. It's really just to avoid having to explicitly convert glm vectors to bullet vectors (for instance) by passing each coordinate manually. Also, to make the process easier if I for some reason want to eventually change my basis vector to something else or implement SIMD or something. I did write an assignment operator which seems to have mostly fixed it. Only pain is I have to manually write out all the constructors, but I guess that's to be expected.

It feels like I should use CMake or something to generate them, but on the other hand I won't be distributing the source code, so no need for using CMake to make sure whoever is doing the build is using a compiler that supports all the C++11/14 features used, where they have SDL installed, etc.

Subjunctive posted:Swift has at times been brutal to work in because of the compatibility breaks and the fact that Xcode can’t span versions. Want to bisect a span that includes a toolchain upgrade? Bring your own bourbon.

(Although I'm not sure where to draw the line between "the Swift team made a mistake" and "the Xcode team made a mistake.") Plus, a substantial amount of Swift is still built on top of ObjC and depends on ObjC interop, and the rules by which that happens are not exactly intuitive.

Con: you'll be doing some duplicate build configuration work. Pro: cmake is a crappy, crufty mess that should be shunned. Call it even? More seriously, I think it depends on how complex your build will be. Are you just going build your stuff and link some external binaries? Doing that twice in the native environment is probably less work than setting up something cross platform. Are you going to run some external processes to generate LLVM bytecode that you'll compile into your application to enable runtime linking with your bespoke internal compiler? You may want to a) re-examine the life choices that lead you to this precipice and b) only set that up once. It also depends on the choices made by your external dependencies, if they have an extensive cmake module then using it can save you a lot of grunt work even on a single platform. I wouldn't want to build against, say, Qt without using their cmake module.

CMake is a giant pile of poo, but it's still completely fine for simple things and you don't want to be duplicating complex things. Developing with a cmake-generated Xcode project is completely fine. I've never had it be meaningfully worse than with an artisinal hand-crafted project file. Recent versions of Visual Studio can skip the project file generation completely and just open cmake projects directly.

I completely agree that C++ is missing a reasonable, standardized build procedure, and CMake has its flaws, but there are ways to make this process less of a pain in the rear end. You can have variables hold groups code:code:You can also automate the build file generation either with a bash/python script or with CMAKE GUI, but neither of these are pretty or easy, but it's a one-time setup thing. Also, CLion has a lot of nice features for making CMake less annoying, like automatically detecting your source groups and asking which variable to add new source files to.

Subjunctive posted:I think better tooling would have made it much smoother, assuming that the Swift team didn’t prefer the big hits to force people along. That’s the exact opposite of our perspective: we don’t like there being big hits because it makes it harder for people to keep up. I think we’ve actually done a pretty good job on the upgrade tooling. It’s just a hard problem because you really, really don’t want to silently break the behavior of code. The 1-to-2 upgrade was awful because the language changes (like error handling) were very difficult to upgrade. The 2-to-3 transition was bad mostly because there were just so many language and SDK changes. But the reason we made all those changes in 3 was to get the language in a more stable state, and that seems to have worked; everything I’ve heard is that the 3-to-4 transition is painless, and that’s likely to be the rule going forward.

No, you just add the new file to CMakeLists.txt and then hit build twice in the IDE. Cmake checks on every build if the project file needs to be regenerated.

I’ve also heard that, but I’m talking about co-existence tooling, not upgrade help. If I have 10 modules in my program, I can write them in ObjC, C++, and Swift, and convert modules between those on their own schedules. Xcode can mix those different languages painlessly. I can’t AFAICT upgrade any module from Swift 3 to Swift 4 unless I do all of them at the same time that I flag-day my CI machines and all developers. If 10 modules becomes 75 it’s even worse. Developers with 10KLOC and a dozen team members can handle it, but Swift seems so much nicer than ObjC for large scale development that it’s a shame the version interactions make it so painful. I have been assuming that Apple has some special system for this so that All The Builds don’t come screeching to a halt on Swift version days, but I unsurprisingly haven’t heard tell of it.

Definitely clarify more than that - do you want to end up with an n by 2 array? Maybe say what domain this is for? How is the 2d array going to be used? I kinda feel like that's the sort of thing that you ought to figure out how to piece together on your own, it's trivial if you know how things work and dangerous if you don't. Any reason not to loop through and copying wouldn't work.

Arrays are prove to out of bounds errors, my concern would be that you'd be given a firm rigid way of doing something, and only learn to manipulate that without understanding it. I see C as somewhat portable assembly language and is hard for me to think of it as a language whose abstractions I can trust without knowing how they work all the way. So like, I suspect some XY problem here - what are you trying to store in a 2d array? How many values are you storing? 20 or 100 are both reasonable answers but you should be able to answer before you write any code. If you want points on a n by n coordinate grid you want array[n][n]. If you want two arrays of size n, you could use an array[10][2], but I'd probably just use two arrays instead. It might be easier to post a (small) snippet of code and how it's defying expectations if you've already written something.
