Readline

[4-stroke]

I'm trying to compile fim from here:
http://mirrors.aixtools.net/sv/fbi-improved/
Configure complains:

Code: [Select]

checking for rl_replace_line in -lreadline... no
configure: error: *** GNU readline library headers not found !  please install them or run ./configure --disable-readline ***I've installed readline.tcz and readline-dev.tcz.

Did you set the pkg-config path as mentioned here?

http://wiki.tinycorelinux.com/tiki-index.php?page=Creating+Extensions

specifically-
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

Yes I did. And the compiler flags.

Have a look in config.log - sometimes the error message does not exactly match the actual error that occurred.

There's this:

Code: [Select]

configure:10798: checking for rl_replace_line in -lreadline
configure:10834: g++ -o conftest -g -O2   conftest.cpp -lreadline  -lcurses
       -lm  >&5
/usr/local/bin/ld: cannot find -lcurses
collect2: ld returned 1 exit status
configure:10840: $? = 1
configure: failed program was:
| /* confdefs.h.  */And this:
 

Code: [Select]

/* Override any GCC internal prototype to avoid an error.
|    Use char because int might match the return type of a GCC
|    builtin and then its argument prototype would still apply.  */
| #ifdef __cplusplus
| extern "C"
| #endif
| char rl_replace_line ();
| int
| main ()
| {
| return rl_replace_line ();
|   ;
|   return 0;
| }
configure:10858: result: no
configure:10870: error: *** GNU readline library headers not found !  please install them or run ./configure --disable-readline ***

..so it's probably libcurses that's missing - you could try the ncurses-lib.tcz/ncurses-lib-dev.tcz extensions

[curaga]

libcurses is in the base. Do you have base-dev loaded?

libncurses is in the base, this is looking for libcurses which I don't see in the base.
The headers are in base-dev, but I don't see an actual libcurses 

Have you tried this?

Code: [Select]

sudo ln -s /lib/libncurses.so /lib/libcurses.so
sudo ldconfigThis will make a link to libncurses, should work...

Have you tried configuring with --disable-readline?

[curaga]

Hm, I thought there still was the ld redirection script curses -> ncurses from LFS in base-dev. I guess it was forgotten at some point. Juanito, could it be added?

[Juanito]

Sure - give me a day or two to get around to it

This worked. There was some warnings though, got to check them out.
Thanks!

Edit: Duh! Forgot to install readline.tcz again. In fact the only thing needed was the symlink.
