- Subject: PATCH to get bc 1.06-1 to build with readline support under Cygwin
I installed the bc source package (bc-1.06-1-src.tar.bz2) and configured
it to build with readline support as follows:
cd /usr/src/bc-1.06-1
./configure --with-readline --prefix=/usr/local
The build fails with a syntax error related to the readline support:
$ make
...
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I. -I./../h -g -O2 -Wall -funsigned-char -c scan.c
scan.l:146: error: conflicting types for `readline'
/usr/include/readline/readline.h:277: error: previous declaration of `readline'
I made the following small change to the source code in scan.l and bc
builds just fine:
--- scan.l.orig 2004-02-13 16:22:26.847595200 -0500
+++ scan.l 2004-02-13 16:21:55.702811200 -0500

I hope the Cygwin bc maintainer can integrate this change. bc is much
nicer to use when it has readline support.
