undefined reference in g++ compilation

[pancho_hideboo]

I failed in building g++ program.

g++ -o hoge hoge.o .... -lm -lncurses -lreadline -lhistory

hoge.o:hoge.cc:(.text+0x181): undefined reference to `_LINES'
hoge.o:hoge.cc:(.text+0x18f): undefined reference to `_COLS'
hoge.o:hoge.cc:(.text+0x199): undefined reference to `_TABSIZE'
hoge.o:hoge.cc:(.text+0x2418): undefined reference to `_stdscr'
hoge.o:hoge.cc:(.text+0x37e6): undefined reference to `_COLS'
hoge.o:hoge.cc:(.text+0x37ec): undefined reference to `_LINES'
hoge.o:hoge.cc:(.text+0x3805): undefined reference to `_TABSIZE'
hoge.o:hoge.cc:(.text+0x3858): undefined reference to `_ESCDELAY'
hoge.o:hoge.cc:(.text+0x3980): undefined reference to `_stdscr'

Is there any lack for library ?

Have you checked if the Makefile file contains the paths to all the necessary includes for your code, or if all the files and directories referred there are really present on respective folders ?

Thanks for replying.

I suspect lack of "#include <???.h>" in hoge.cc.

the errors are for 'curses' package. either #include <curses.h>

or

the library path for curses.so is not in order.

Of course, I suspect library specified order in linking.

-lm -lncurses -lreadline -lhistory

-lncurses -lreadline -lhistory -lm

However I can not succeed in compilation.

 

[srizbf]

did you try including the -I /-L switch if the curses is not in search path?

 

[srizbf]

if -I/-L switch has the same error message , then -lncurses should be the last in linking as:

lm- -lreadline -lhistory -lncurses
