Lua-5.2.2

lua-5.2.2發(fā)布已有一段時(shí)間了，最近在redhat Linux平臺(tái)編譯時(shí)報(bào)錯(cuò)。這里給出解決方案，或許對(duì)某人會(huì)有幫助。

編譯報(bào)錯(cuò)，如下：

lua@home> make linux  ... gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_LINUX    -c -o lstrlib.o lstrlib.c gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_LINUX    -c -o ltablib.o ltablib.c gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_LINUX    -c -o loadlib.o loadlib.c gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_LINUX    -c -o linit.o linit.c ar rcu liblua.a lapi.o lcode.o lctype.o ldebug.o ldo.o ldump.o lfunc.o lgc.o llex.o lmem.o lobject.o         lopcodes.o lparser.o lstate.o lstring.o ltable.o ltm.o lundump.o lvm.o lzio.o lauxlib.o lbaselib.o lbitlib.o     lcorolib.o ldblib.o liolib.o lmathlib.o loslib.o lstrlib.o ltablib.o loadlib.o linit.o  ranlib liblua.a gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_LINUX    -c -o lua.o lua.c gcc -o lua   lua.o liblua.a -lm -Wl,-E -ldl -lreadline  /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `PC' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetflag' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetent' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `UP' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tputs' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgoto' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetnum' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `BC' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetstr' collect2: ld returned 1 exit status make[1]: *** [lua] Error 1 make[1]: Leaving directory `/home/lua/lua-5.2.2/src' make: *** [linux] Error 2

由于lua編譯依賴readline庫(kù)，而其依賴ncurses庫(kù)，但沒(méi)有指定，所以出現(xiàn)“未定義的符合引用”錯(cuò)誤。需要修改${LUA_DIR}/src/Makefile中l(wèi)inux編譯target，在SYSLIBS變量中追加‘-lncurses’選項(xiàng)即可。修改后，如下：

  1. linux:
  2.         $(MAKE) $(ALL) SYSCFLAGS="-DLUA_USE_LINUX" SYSLIBS="-Wl,-E -ldl -lreadline -lncurses"
  3.
