lua手工编译遇到的问题

适用于没有足够安装权限的用户

第一步是 make

第二步   make linux
这里出错了，提示如下
luaconf.h:275:31: error: readline/readline.h: No such file or directory
luaconf.h:276:30: error: readline/history.h: No such file or directory
lua.c: In function 'pushline':
lua.c:182: warning: implicit declaration of function 'readline'
lua.c:182: warning: assignment makes pointer from integer without a cast
lua.c: In function 'loadline':
lua.c:210: warning: implicit declaration of function 'add_history'
make[2]: *** [lua.o] Error 1
make[2]: Leaving directory `/data/source/lua-5.1.4/src'
make[1]: *** [linux] Error 2
make[1]: Leaving directory `/data/source/lua-5.1.4/src'

make: *** [linux] Error 2

这是因为没有readline-devel ncurses-devel

如果自己有足够的权限，直接

yum install -y readline-devel ncurses-devel

或者 下载两个压缩包，执行./configure make make install

因为自己没有足够的权限，采用修改lua的makefile的方法。

lua的src目录的Makefile

修改1：

CFLAGS= -O2 -Wall -Wextra -DLUA_COMPAT_5_2 $(SYSCFLAGS) $(MYCFLAGS) -I/data/app/project

注意/data/app/project是自己编译readline的目录，注意readline的目录，编译时修改一下文件夹名，不要带版本号，因此lua.c中使用的头文件是readline/readline.h

修改2：

MYLDFLAGS=-L/data/app/project/readline -L/data/app/project/ncurses/lib

这两个目录，是编译好的libreadline.a和libncurses.a所在的目录。

修改3：

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

实际应该修改readline的makefile，但短时间内修改正确，直接修改lua的makefile了。

如果没有ncurses，会报下面的错误：

gcc -std=gnu99 -o lua  -L/data/app/project/readline lua.o liblua.a -lm -Wl,-E -ldl -lreadline
