Subject:	GNU's bc with readline library?
Date:	Tue, 2 Jan 2001 14:31:26 -0000
MIME-Version:	1.0

While trying to compile GNU's bc with the readline library:

sysop AT ZUK02-0544 ~/bc-1.06
$ ./configure --with-readline
loading cache ./config.cache
... (snip)
checking for readline in -lreadline... (cached) yes
checking for readline/readline.h... (cached) yes
Using the readline library.
... (snip)
creating config.h

I get:

sysop AT ZUK02-0544 ~/bc-1.06
$ make
... (snip)
Making all in bc
make[2]: Entering directory `/home/sysop/bc-1.06/bc'
... (snip)
gcc  -g -O2 -Wall -funsigned-char  -o bc  main.o bc.o scan.o execute.o
load.o st
orage.o util.o global.o ../lib/libbc.a -lfl -lreadline -lncurses
scan.o(.text+0x155b): undefined reference to `rl_instream'
collect2: ld returned 1 exit status
make[2]: *** [bc] Error 1
make[2]: Leaving directory `/home/sysop/bc-1.06/bc'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/sysop/bc-1.06'
make: *** [all-recursive-am] Error 2

I see:

$ objdump --syms bc/scan.o | grep rl_instream
[ 60](sec  0)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _rl_instream

and that rl_instream is defined:

$ nm --print-file-name /usr/lib/libreadline.a | grep 'rl_instream'
/usr/lib/libreadline.a:readline.o:00000024 D _rl_instream
... (snip)

Any hints?

Without readline it compiles and links fine.

thanks,
