| 00:04 | <@celticminstrel> | I want to use C++14 or C++17. :( Do I have it literally build libc++ myself? |
| 00:04 | <@celticminstrel> | ^have to |
| 00:09 | <~Vornicus> | maaaaaaaaaaaathtaaaaacuuuulaaaaaaaar |
| 00:16 | <@celticminstrel> | I'm assuming that's not supposed to be an answer to me. |
| 00:16 | <&McMartin> | I assume --std=c++14 isn't working for you |
| 00:17 | <@celticminstrel> | The compiler is too old; currently installing a newer one. |
| 00:17 | <@celticminstrel> | But the real issue is with the standard library, I think, especially if I want C++17. |
| 00:17 | <&McMartin> | That should be part of your compiler suite, as it were |
| 00:18 | <@celticminstrel> | Except that libc++ is installed in the system and apparently it is Very Dangerous to replace it. |
| 00:18 | <&McMartin> | Yes, especially on Apple, where it uses magic undocumented symbols everywhere and links against those |
| 00:18 | <@celticminstrel> | MacPorts actually makes "libcxx" an empty package. |
| 00:19 | <@celticminstrel> | Yes, on Apple. |
| 00:20 | | * Vornicus defeats another hunk of math, gets to the part where he has to put it all together. How does he want the file format to look. |
| 00:20 | <~Vornicus> | Well, the data format. |
| 00:29 | <~Vornicus> | So: I have a polygon, which suggests individual points; however, some edges (for most things, 0 or 1 edges) require an additional piece of information. |
| 00:44 | <~Vornicus> | that additional piece of information is a single number. |
| 01:13 | <&[R]> | Does MacOS not have anything like LDPRELOAD or other methods of changing the location of libraries? |
| 01:15 | <&McMartin> | Answer to that is "Yes, but it doesn't work the way LDPRELOAD does because LDPRELOAD is disastrous" |
| 01:15 | | * Vornicus apparently did this wrong. |
| 01:15 | <~Vornicus> | I have a git project that is supposed to have a submodule in it |
| 01:16 | <&McMartin> | "And it might not work because the whole issue here is that the OS library calls you make may rely on a different libc" |
| 01:16 | <~Vornicus> | But I appear to have not correctly set it as a submodule. |
| 01:16 | <&McMartin> | Now, it doesn't fail the way LDPRELOAD does, where it calls into a library that isn't the one it expects; it will load both libcs |
| 01:16 | <&McMartin> | But now you have two copies of libc in your address space and that makes life exciting if you were hoping things like errno to work |
| 01:17 | <~Vornicus> | now I have to figure out how to make it properly a submodule. |
| 01:17 | <&McMartin> | (Every call that ends up in some other dynamic library in macOS, like in Windows, carries the identifier of the library said symbol is in.) |
| 01:18 | <&McMartin> | (macOS's binary format has a separate notion for specifically interposing/replacing symbols, but you need to do compile-time magic within the interposing library to make that happen) |
| 01:58 | <&McMartin> | Man |
| 01:58 | | * McMartin adds a byte to his program, watches the result shrink by a byte |
| 02:12 | | * Vornicus manages it |
| 02:31 | <&McMartin> | Also, man, that feeling when you realize self-modifying code will be easier than having a pointer variable :( |
| 02:32 | <&McMartin> | Not *faster* (though it is, by a trivial amount), but *actually easier* |
| 02:36 | <~Vornicus> | man |
| 02:37 | <&McMartin> | I've mentioned before that 6502 is bad at pointers |
| 02:37 | <&McMartin> | Let me reiterate: 6502 is bad at pointers |
| 02:41 | <@celticminstrel> | Oh my. |
| 02:44 | <~Vornicus> | Ah yes |

| 03:27 | <@celticminstrel> | So, what could be the cause of an exception not being caught even though there's a catch clause? |
| 03:27 | <@celticminstrel> | (And it is caught by reference, just FTR.) |
| 03:28 | <@celticminstrel> | Could that be caused by incompatibility between the libc++ it was built against and the libc++ it's dynamically loading? |
| 03:28 | <@celticminstrel> | I feel like an incompatibility should've instead produced an "unknown symbol" type of error though... |

| 04:01 | <@celticminstrel> | Hmm, apparently C++14 works with clang 3.7 and whatever version of libc++ it's using. |

| 07:13 | <~Vornicus> | I've done the math and figured out how to use real arcs in the physics engine. |
| 07:14 | <~Vornicus> | The problem I've been poking at (alongside being super duper ADD) is including the arcs as part of polygons, and building the systems to handle the creation of same. |
