UGentoo: Kungani ngakhetha ukuhlanganisa izinhlelo zami?

Yebo, uma unikezwa ukwamukelwa okuhle kokuthunyelwe kwami ​​kwangaphambilini, ngiza ukukutshela okuthe xaxa ngokusatshalaliswa kwami ​​engikuthandayo, iGentoo Linux. Ngiyathembisa ukuthi lokhu okuthunyelwe kuzoba nemininingwane ejabulisayo ezokusiza ukuthi uqonde kancane ngezinganekwane ezivela ngaphambi kwesabekayo ukuhlanganiswa yesoftware. Ngiyathembisa futhi ukuthi lolu lwazi luzoba wusizo kumhlahlandlela olandelayo wokufaka we-Gentoo Linux ngezinyathelo ezingama- ~ 20 (angikazibali kahle okwamanje, kepha ngicabanga ukuthi zingaphansi kakhulu). Ngaphandle kokuqhubeka, ake siqale:

Yini ukuhlanganiswa?

Kuyinkqubo eyenziwa uhlelo (oluvame ukubizwa ngokuthi ngumhlanganisi) ukuguqula ikhodi ebhalwe ngolimi lomuntu (amafayela we-C, C ++, njll.) Ibe yikhodi engaqondakala ngomshini (ikhodi kanambambili). Ake sibheke lesi sibonelo esilandelayo:

Lolu uhlelo lwethu C oluncane (uma ufuna amanye ama-tutorials we-C ngokuhamba kwesikhathi, ngizojabula futhi ukukukhombisa okuncane engikufundile ngalesi sikhathi). Manje ake sibheke ukuthi okukhiphayo kubukeka kanjani ngemuva kokuhlanganiswa.

Muhle, akunjalo? Is Yilokhu umshini wethu okuqondayo ukuthi ukwazi ukubhala lokho okuncane "Sawubona" ​​esigungwini sethu njalo lapho uhlelo lwenziwa.

Inqubo yokwakha:

Njengoba kungasizi ngalutho ukuba nohlelo oluprinta u- "Sawubona" ​​olula esibukweni, njengoba amafayela we-.c ne-.h egcwele amaphrojekthi (njengakuzo zonke izilimi ezihlelayo). Ukuze kwenziwe inqubo yokuhlanganiswa ibe lula kancane, kwavela amathuluzi amasha, omele konke kunakho konke umyalo ukwenza.

Make thatha ifayela Makefile njengesiqalo futhi ihlanganisa okudingekayo ukudala okuzosebenza kokugcina, kwezinye izimo lesi sinyathelo sidinga ukusebenzisa ifayela elibiziwe configure ukukwazi ukwaba okuguqukayo okumbalwa okudingekayo ukuze umhlanganisi ahlanganise (thethelela ukungafuneki) ifayela eliwusizo.

Kungakho ezifundisweni eziningi sizothola izinyathelo ezilandelayo:

Umlingo we ./configure:

Ukukukhombisa enye yezimfihlo ezifihliwe nezijabulisa kakhulu zekhodi yomthombo, sizoya kukhodi yomthombo yohlelo sonke esilwazi kahle, sudo. Okokuqala izinyathelo ezijwayelekile, kepha ngizoma lapho ./configure  ukubakhombisa okuthile okukhethekile.

Lokhu kuzobuyisa uhlu olude lwezinketho, phakathi kwazo engizokukhombisa lona oludonsa amehlo ami kakhulu.

--with-insults... njengoba igama lisho, ihlanganisa iSudo nge ukuhlukumeza 😀 isici esimnandi esikuvumela ukuthi uthumele isithuko kumsebenzisi ngaso sonke isikhathi lapho benza iphutha kwi-password yabo. Yenzelwe ini? Hhayi kungekudala, kodwa kwenza iphuzu elilodwa licace. Kunezinkulungwane zezinketho ezingafiki ngokuzenzakalela ekusatshalalisweni okuningi.

Njengoba unjalo, kukhona abanye abaningi abangahle basebenze ekusatshalalisweni kwamakhodi kanambambili futhi ongasoze wawasebenzisa, noma kuzoba khona okudingayo, kepha ngeke beze ne-binary yakho esatshalaliswe ngokusemthethweni, okusho ukuthi isibuyekezo ngasinye sizoba ibhukwana.

Qalisa ubumnandi ku-Gentoo:

Sesibonile ukuthi zingaki izinketho esingahle sizilahle noma sihudule ngezinhlelo ezihlelwe ngaphambilini. Kepha manje ake sigxile kancane enkingeni ehlelwe ngaphambilini.

Performance:

Wake wazibuza ukuthi kungani imishini emisha ibukeka ishesha nje kancane uma iqhathaniswa naleyo engeyona eyesimanje? Uma iprosesa ingcono, kune-RAM eningi, konke kungcono, kungani ungahambi ngokushesha? Impendulo ilula ... ukuhlanganiswa.

Ake sithathe isibonelo esisebenzisekayo.

Izinhlelo zami zihlanganiswa nenketho --march=broadwell... lokhu kungenxa yokuthi iprosesa lami libanzi (i-i7). Okubi kulokhu? ayikho iprosesa ngaphambi kwe-Broadwell ekwazi ukubona le kanambambili. Kuleli qophelo kufanele ulibone ngokucacile, uma ngihlanganisa nefayela le- –Mashi  Ngokuqondile, konke okungenhla ngeke kusebenze ... ngakho-ke amaphakheji kanambambili asekela kanjani izinhlobo eziningi kangaka zehadiwe? Kulula, bahlanganisa nenketho encane kunazo zonke 🙂 lokhu kuqinisekisa ukuthi zonke izinhlobo zehadiweware zizokwazi ukuyifunda (okungenani ukuhambisana).

Inkinga yangempela ... uma usebenzisa izinhlelo ezihlanganiselwe i3 ... Onke amandla we-i7 yakho (noma ama-analogies ayo e-AMD) ayamoshwa !! Akudabukisi lokho? 🙁

Ukuvumelana nezimo:

Njengoba abathuthukisi be-Gentoo bahlakaniphile kakhulu, yonke le nqubo yetiyela, ./configure, make, etc ... ithathelwe indawo ngamandla I-Portage. Zonke lezi zilungiselelo zokufuna ukwazi seziqanjwe kabusha ngamafulegi e-USE, ngakho-ke uma ufuna isilungiselelo esithile, awudingi ukufaka ikhodi yomthombo, vele usethe okuguqukayo. Nasi isibonelo sendlela yokukwenza ngeSudo ku-portage. Okokuqala sizobona ukuthi yiziphi izinketho esinazo ekucushweni kwethu kwamanje nge i-equery.

Njengoba sibona, izinketho ezibomvu zenziwa zasebenza, eziluhlaza okwesibhakabhaka azikho, kahle… wonke umuntu angafunda inganekwane 🙂

ake sithi ngifuna ukufaka inketho ...

Kulula njengokungeza umugqa kufayela elibiziwe sudo (igama liyabhekiswa) ngaphakathi /etc/portage/package.use/. Ngalokhu, ngokuzayo lapho sifaka isudo izositshela ukuthi izophindwaphindwa ngenketho eyenziwe yasebenza.

Uma sinikela, YEBO, Okufanele ukwenze nje ukulinda kancane bese u-voila 🙂 elula njengale.

Imicabango yokugcina:

Yebo, sesivele sibonile ukuthi kulula kangakanani ukuphatha ukusebenza okwengeziwe kwi-Gentoo, esivumela ukuthi sengeze, sisuse, noma siguqule izinketho ngaphakathi kwezinhlelo zethu esizithandayo. Sibonile futhi ukuthi ukusebenza kwezinhlelo zethu kuncike kanjani kakhulu kokuguqukayo esikuhlanganisa nakho. Uma unomshini omusha sha, iGentoo inketho yakho engcono kakhulu. Uma unomshini omdala kakhulu, i-Gentoo nayo inketho yakho (noma kuthatha isikhathi ukuhlanganisa, izinhlelo zokugcina zizokhanya kakhulu).

Ngizobhala umhlahlandlela wami wokufaka we-Gentoo kungekudala, bobabili abathandi be-SystemD nabahloli be-OpenRC (ngisebenzisa i-systemd ne-GNOME). Ngendlela, enye inzuzo enkulu yeGentoo yikhono lokwenza njalo khetha konke okungaphakathi kohlelo lwakho, futhi uma ngithi konke kunjalo Konke.

Uma uphuthelwe okuthunyelwe kwami ​​kokuqala, nasi isixhumanisi:
