[R] rl_callback_read_char error on Solaris 7

[Yuelin Li]

This question is about compiling R-1.6.2 from source on a 
Sparcstation-20 machine running Solaris 7, gcc-2.95.3 and 
readline-4.2 (both gcc and readline from sunfreeware.com).  

I searched the r-help archive and the FAQ.  The errors seem to be 
related to the binary readline libraries, and I have 
/usr/local/lib/libreadline.a,libreadline.so@, and 
libreadline.so.4.

The attached errors are from config.log.  ./configure finds 
readline header files in /usr/local/include/readline.  I can make 
and install R, but command line editing and savehistory() do not 
work.   

Suggestions are appreciated.

Yuelin Li.
