C ++ kunye CMake - abazalwana ngonaphakade, inxalenye II

Kwinxalenye engaphambili Eli bali eyonwabisayo wathetha ngokuququzelela ilayibrari header ngaphakathi CMake ukwakha inkqubo generator.

Ngeli xesha siya kongeza ithala leencwadi elihlanganisiweyo kuyo, kwaye sithethe malunga nokudibanisa iimodyuli enye kwenye.

Njengangaphambili, abo bangenamonde banako ngoko nangoko yiya kwindawo yokugcina ehlaziyiweyo kwaye ubambe yonke into ngezandla zakho.

Yahlula

Into yokuqala ekufuneka siyenzile ukufezekisa injongo yethu ephezulu kukwahlulahlula isoftware esiyiphuhlisayo ibe ziibhloko ezizimeleyo, ezizimeleyo ezifanayo ngokwembono yomsebenzisi.

Kwinxalenye yokuqala, ibhloko enjalo eqhelekileyo yachazwa - iprojekthi enelayibrari yentloko. Ngoku masenze ithala leencwadi elihlanganisiweyo kwiprojekthi yethu.

Ukwenza oku, makhe sithathe ukuphunyezwa komsebenzi myfunc ngokwahlukileyo .cpp-ifayile:

Emva koko sichaza ithala leencwadi eliza kuqulunqwa (myfeature), eya kubandakanya into efunyenwe kwisinyathelo sangaphambili .cpp-ifayile. Ithala leencwadi elitsha ngokucacileyo lifuna iiheader ezikhoyo, kwaye ukuze kubonelelwe ngoku, linokuthi kwaye libotshelelwe kwinjongo ekhoyo. mylib. Ngaphezu koko, uxhulumaniso phakathi kwabo luluntu, oku kuthetha ukuba yonke into ekujoliswe kuyo iya kudibaniswa myfeature, iya kufumana ngokuzenzekelayo umthwalo kunye nethagethi mylib (ngakumbi malunga neendlela zokunitha).

Kufuneka kuqatshelwe ukuba injongo myfeature, ngoko mylib isibizo esinesimaphambili senziwe Mylib::. Okufanayo kubhalwe kuzo zombini iinjongo xa uthumela ngaphandle ukuze ufakelwe kwisixokelelwano. Oku kwenza kube lula ukusebenza ngokufanayo kunye neenjongo kuyo nayiphi na inkqubo yokubophelela.

Emva koku, okuseleyo kukudibanisa iimvavanyo zeyunithi nethala leencwadi elitsha (umsebenzi myfunc ikhutshwe kwisihloko, ke ngoku kufuneka udibanise):

Izihloko (Mylib::mylib) ngoku awudingi kudibanisa ngokwahlukeneyo, kuba, njengoko sele kukhankanyiwe, ziqhagamshelwe ngokuzenzekelayo kunye nethala leencwadi (Mylib::myfeature).

Kwaye songeze iinuances ezimbalwa zokuqinisekisa imilinganiselo yokhuselo ethathela ingqalelo ithala leencwadi elitsha elifikileyo:

Unokongeza iilayibrari ezininzi, eziphunyeziweyo, njl. Akukhathaliseki ukuba ziqhagamshelwe kangakanani na phakathi kweprojekthi. Eyona nto ibalulekileyo kukuba zeziphi iithagethi lujongano lwemodyuli yethu, oko kukuthi, zincamathele.

Yoyisa

Ngoku sineemodyuli zebhloko eziqhelekileyo, kwaye sinokuzilawula: zidibanise kwisakhiwo sayo nayiphi na into enzima, ukuyifaka kwisistim okanye ukudibanisa kunye ngaphakathi kwenkqubo yendibano enye.

Ufakelo kwisixokelelwano

Enye yeenketho zokusebenzisa imodyuli kukufaka imodyuli yethu kwisistim.

cmake --build ΠΏΡƒΡ‚ΡŒ/ΠΊ/сборочной/Π΄ΠΈΡ€Π΅ΠΊΡ‚ΠΎΡ€ΠΈΠΈ --target install

Emva koko, idityaniswe kuyo nayiphi na enye iprojekthi isebenzisa umyalelo find_package.

find_package(Mylib 1.0 REQUIRED)

Uqhagamshelwano njengemodyuli engaphantsi

Enye inketho kukudibanisa ifolda kunye neprojekthi yethu kwenye iprojekthi njengemodyuli engaphantsi usebenzisa umyalelo add_subdirectory.

Sebenzisa

Iindlela zokubopha zahlukile, kodwa umphumo uyafana. Kuzo zombini ezi meko, iinjongo ziya kufumaneka kwiprojekthi kusetyenziswa imodyuli yethu Mylib::myfeature ΠΈ Mylib::mylib, enokusetyenziswa, umzekelo, ngolu hlobo:

add_executable(some_executable some.cpp sources.cpp)
target_link_libraries(some_executable PRIVATE Mylib::myfeature)

Ngokukodwa kwimeko yethu, ithala leencwadi Mylib::myfeature kufuneka idityaniswe xa kukho imfuneko yokudibanisa nethala leencwadi libmyfeature. Ukuba kukho izihloko ezaneleyo, ngoko kuyafaneleka ukusebenzisa ithala leencwadi Mylib::mylib.

Iithagethi zeCMake zinokukhohlisa, umzekelo, zijolise kuphela ukuhambisa ezinye iipropathi, ukuxhomekeka, njl. Kwangaxeshanye, ukusebenza nabo kwenzeka ngendlela efanayo.

Nantso into ebesiyidinga.
