Yadda ake Sanya Lua a cikin Linux

Ana samun fakitin Lua a cikin ma'ajiyar hukuma na manyan rarraba Linux, zaku iya shigar da sabon sigar ta amfani da mai sarrafa fakitin da ya dace akan tsarin ku.

$ sudo apt install lua5.3	                #Debian/Ubuntu systems 
# yum install epel-release && yum install lua	#RHEL/CentOS systems 
# dnf install lua		                #Fedora 22+

Lua: Fakitin Lua na yanzu a cikin ma'ajin EPEL shine 5.1.4; don haka don shigar da sakin na yanzu, kuna buƙatar ginawa da shigar da shi daga tushe kamar yadda aka bayyana a ƙasa.

Da farko, tabbatar da cewa kuna da kayan aikin haɓakawa da aka shigar akan tsarin ku, in ba haka ba ku aiwatar da umarnin da ke ƙasa don shigar da su.

$ sudo apt install build-essential libreadline-dev      #Debian/Ubuntu systems 
# yum groupinstall "Development Tools" readline		#RHEL/CentOS systems 
# dnf groupinstall "Development Tools" readline		#Fedora 22+

Sa'an nan don ginawa da shigar da sabuwar sakin Lua (version 5.3.4 a lokacin wannan rubutun) na Lua, gudanar da umarni masu zuwa don zazzage kwandon fakitin, cirewa, ginawa da shigar da shi.

$ mkdir lua_build
$ cd lua_build
$ curl -R -O http://www.lua.org/ftp/lua-5.3.4.tar.gz
$ tar -zxf lua-5.3.4.tar.gz
$ cd lua-5.3.4
$ make linux test

Da zarar kun shigar da shi, gudanar da fassarar Lua kamar yadda aka nuna.

Ajiye kuma rufe fayil ɗin. Sannan gudanar da shirin kamar yadda aka nuna.
