| [Coke] | jdv: I recommend at a minimum, that for things we go, any file with a commit date in 2022 be upgraded. I've seen folks do *any file*, regardless of last update date. If you have anything crazier, bounce it off codesections, probably. | 01:35 | |

| you don't need the role to reproduce it | |||
| m: package Foo { my class Some::Baz { } }; Foo::Some::Baz.new | 08:39 | ||
| camelia | Could not find symbol '&Baz' in 'Foo::Some' in block <unit> at <tmp> line 1 |

| elcaro | mental blank... what's the sub version of $class."$method"()... ie, how can i calls sub `foo()` if `$var='foo'` | 12:02 | |

| frank26 | Hi, I have a problem wrt to building a module of mine with the debian package of rakudo. This is the module github.com/soundart/perl6-tweetnacl. I do "zef install ." and end with "/usr/bin/ld: cannot find -latomic_ops" | 20:09 | |
| If I remove atomic_ops from the generated Makefile the module seems to be working. | 20:11 | ||
| [Coke] | ? what is -atomic_ops? | 20:14 | |
| ? what is -latomic_ops? | |||
|
20:15
Darkcoal left
|
|||
| [Coke] | the only atomic_ops I have in my makefile is: | 20:16 | |
| -I'/Volumes/BUKKIT/Users/coke/sandbox/rakudo/install/include/libatomic_ops' \ | |||
|
20:17
Darkcoal joined
|
|||
| [Coke] | File::Which should update to check for raku as a test instead of perl6 | 20:19 | |
| frank26 | Hm that seems to be the directory containing the headers files of that library. -latomic_ops is for the linker. | ||
| [Coke] | I assume you mean the rakudo makefile, though it's not clear how that impacts your module. | 20:20 | |
| (I was able to do a zef install --dry . in the module checkout, no errors) (I'm on OS X, though) | 20:21 | ||
| frank26 | "zef" creates for my module a Makefile. In that Makefile is a linker line referring to atomic_ops | 20:23 | |
|
20:23
anight[m] joined
|
|||
| ugexe | maybe something from LibraryMake that you use? github.com/retupmoca/P6-LibraryMak...#L144-L147 | 20:24 | |
| [Coke] | ah. issue with LibraryMake perhaps? Or your debian package of rakudo being misconfigured? | 20:25 | |
| frank26 | Yes I think this github.com/soundart/perl6-tweetnac...file.in#L9 gets expanded with %LIBS% | 20:29 | |
|
20:29
CIAvash joined
|
|||
| [Coke] | it concerns me that debian's version is still calling itself Perl 6 | 20:29 | |
|
20:29
AlexDaniel joined
20:30
Darkcoal left
|
|||
| frank26 | %LIBS% seems to be -lffi -ltommath -latomic_ops -luv -lm -lpthread -lrt -ldl | 20:30 | |
|
20:33
frank26 left
|
|||
| [Coke] | ah, the MoarVM Makefile, not rakudo. Still, don't see a -latomic_ops in mine. | 20:33 | |
|
20:34
frank67 joined
|
|||
| MasterDuke | moarvm uses libatomic_ops, i suspect you need to install the libatomic-ops-dev debian package | 20:34 | |
| [Coke] | Shouldn't the package require it automagically? | ||
| frank67 | Sorry I accidentally left the channel | ||
| [Coke] | (if it's going to die this way?) | ||
| and changed your ID. :) | |||
| and changed your ID. :) | 20:35 | ||
| MasterDuke | but i think it's only because building his module requires compiling some c code | ||
| frank67: if you missed my earlier comment, "moarvm uses libatomic_ops, i suspect you need to install the libatomic-ops-dev debian package" | 20:37 | ||
| frank67 | Yes indeed libatomic-ops-dev solved that. I think I did not find that package, as I searched for atomic_ops ,not atomic-ops. | ||
|
20:39
unclechu joined,
bdju_ is now known as bdju
|
|||
| frank67 | So is this a bug somewhere? My code does not use atomic_ops. Or should I update the readme to give a hint that this package might be required? | 20:40 | |
| MasterDuke | fyi, if you build your own rakudo, moarvm recently gained the ability to use c11's atomic ops instead (assuming you have a supported OS+compiler), so you could pass `--moar-option='--c11-atomics'` to the rakudo Configure.pl call | 20:41 | |
|
20:43
Zgredu[m] joined
|
|||
| frank67 | I am still uncertain: how should I document the build procedure of my code, so that someone else could succeed building it? Does the native call machine require atomic_ops to be linked against the parts of the code I provided? | 20:48 | |
| ugexe | for a debian package you probably shouldnt be running e.g. Build.pm | 20:50 | |
| MasterDuke | i think he's saying he got his rakudo from a debian package, but is installing his module with zef | 20:51 | |
| frank67 | Yes exactly. | 20:52 | |
| ugexe | if you can make it work without LibraryMake maybe try that | ||
| or delete whatever entries from github.com/soundart/perl6-tweetnac...uild.pm#L9 you dont want | 20:54 | ||
| frank67 | I think this is quite hard, especially if there are variants like `--moar-option='--c11-atomics'` around. | 21:00 | |
|
21:10
reportable6 joined
|
|||
| frank67 | I will add a pointer to libatomic-ops-dev (and the other not used libs like ) into the readme for now. The linker seems to prevent the extra libs being added to the shared library libtweetnacl.so | 21:11 | |

Zgredu[m] joined
|
|||
| [Coke] | that also would have solved the issue; I imagine that rakudo will explode if you try to use the atomic ops. | 22:28 | |

| [Coke] | ... except you already installed the dev lib. ah well. | ||
| MasterDuke | i don't believe so, it's just that LibraryMake (or whatever creates the Makefile) is guessing that the include line for the non-rakudo-related code needed to be compiled for that module should be copied from the moarvm build | 22:39 | |
