tmsr - Search: static linking

dorion_road: mircea_popescu gcc refers to c compiler, ave1 said he's working on a genesis based on version 4.9.4. By c library I mean the choice essentially between glibc and musl and dynamic and static linking, e.g. http://logs.ossasepia.com/log/trilema/2019-11-27#1953721

dorion_road: For fundamental strategy decisions such as the static linking knot, I'm really going to have to lean heavily on the technical expertise here.

trinque: yep, just enumerating. what about bundling the necessary libs alongside. afaik this is what steam does, static linking for idiots

asciilifeform: for the l0gz: 'Years ago, a “technical” decision was made by a core gcc developer named Drepper to break static linking. This means that no useful binaries can ever execute on Linux without dynamically linking to certain libraries making the proposition of distributing signed binaries futile, making the proposition of secure software futile, making the proposition of Bitcoin futile, making the proposition of sound money futile, m

asciilifeform: summary in log, iirc was : asciilifeform wrote to rms re the 'libnss' garbage preventing static linking of glibc. rms 0 reply. but when mircea_popescu wrote, rms answered w/ jwzisms.

trinque: upstack, it's not just a step around lack of static linking, but also deterministic reproduction of config state

spyked: diana_coman, I think v.pl will press either side of the http://btcbase.org/patches?patchset=vtools tree (keccak or sha), but not both. also, re. error, vtools_fixes_static_tohex should fix it. I've also encountered the linking error in e.g. http://btcbase.org/log/2018-05-21#1816314 and earlier. ☝︎

mircea_popescu: "no static linking" is how you say "no actual ownership of anything" in the context of computer programming and "i am heavily into consent" is how you say "no static linking" in the context of sexual practice and so fucking following.

asciilifeform: though, i will point out, not on crapple, where static linking is thoroughly impossible as of late

a111: Logged on 2017-06-03 02:35 asciilifeform: ( and prohibits static linking )

asciilifeform: !~later tell mod6 http://wotpaste.cascadianhacker.com/pastes/upCny/?raw=true << makefile. this will work everywhere but crapple, where static linking is entirely dead. ( will work there also if you discard the relevant flags. )

scriba: Logged on 2017-03-28: [23:51:43] <phf> it's not the static linking that gets you, it's the lack of stable abi. binary loads, but fails to do the right thing on system call

asciilifeform: phf: this was the original drepperist excuse for 'shadow banning' static linking, 'oh forget it, no MODERN!11 os has a stable abi'

mircea_popescu: they're forcing the latest in static linking deliberate breakage (+ no doubt other goodies) into the "ecosystem"

asciilifeform: buildroot, at least as seen in 'rotor', is not necessary on bsd!! there is no glibc there !! afaik static linking works normally on known bsd

Framedragger: thestringpuller: yeah you're totally right and i really like the api - it's nice! it does seem that to make sure everything incl hrtf works on a person's PC it needs to be installed to system dirs and then linked dynamically as folks had problems with static linking; and apparently for windows the 'proper' way to do it is to first install creative's openal version, and *then* install openal-soft on top

mircea_popescu: <asciilifeform> but, to briefly rewind, << and following. static linking, not dynamic linking. your "the mechanism described in mircea_popescu's sketch." symbol is not acceptabru.

mircea_popescu: 1 should be easy to expand upon. you are familiar with the issues of maintaining software in the beleaguered c world, from what i've seen in the logs. such as you know, no more static linking now. gotta support utf now. (most relevant here : http://log.bitcoin-assets.com//?date=29-02-2016#1418193 ) ☝︎

phf: openbsd patch as written results in a working build on both linux and openbsd. it introduces necessary ifdefs to ensure cross platform support. the only change that it does to makefile is, at least according to my research, is necessary with some versions of gcc, rather then openbsd specific (has to do with static linking of pthread). without that change build ~can~ produce broken static bitcoind on both openbsd and linux. at the time

mircea_popescu: am i correct in reading between the lines of hanbot's efforts that in point of fact someone carefully packaged a debian/ubuntu "equivalent" of the gcc package that allows static linking which in point of fact and quite pointedly DOES NOT allow static linking ?

ascii_field: 'musl's efficiency is unparalleled in Linux libc implementations. Designed from the ground up for static linking, musl carefully avoids pulling in large amounts of code or data that the application will not use. ... musl features the first post-NPTL implementation of POSIX threads for Linux, and the first aimed at complete conformance and robustness. Thread cancellation has been re-designed to avoid serious race

mats: "There are still too many people out there who think (or even insist) that static linking has benefits. This has never been the case and never will be the case." this guy...

assbot: Static Linking Considered Harmful ... ( http://bit.ly/1IYonUC )

mircea_popescu: "The drawback of using loadable objects is not a problem in the GNU C Library, at least on ELF systems. Since the library is able to load shared objects even in statically linked binaries, static linking need not be forbidden in case one wants to use iconv."

mircea_popescu: funkenstein_ static linking of what ? as far as bitcoind specifically goes, iirc nubbins` reported he managed one.

funkenstein_: am i correct in summing up turd polishing discussions, that once DNS is fully removed static linking will be back on the table?

asciilifeform: 'I do not know where to find the historic references, but yes, static linking is dead on GNU systems. (I believe it died during the transition from libc4/libc5 to libc6/glibc 2.x.)

ascii_field: mircea_popescu: as you probably suspected, static linking as such is broken on extant systems.

decimation: ok I got it to compile on centos6 but I had to add the following to the end of the linking command line: -static-libgcc -Wl,-Bstatic -l pthread_nonshared -Wl,-Bdynamic -l m -l dl

mod6: aight. so yeah, stay tuned. as soon as I get anything working with static libs and static linking of the output object files from the bitcoin source base, I'll give an update.
