Edit report at https://bugs.php.net/bug.php?id=50209&edit=1 ID: 50209 Comment by: post at tentimes dot org Reported by: tcallawa at redhat dot com Summary: Compiling with libedit cannot find readline.h Status: Closed Type: Bug Package: Compile Failure Operating System: Linux (Fedora) PHP Version: 5.2, 5.3, 6 Assigned To: felipe Block user comment: N Private report: N New Comment: It's libreadline-dev you need to add, not readline-dev. But, thanks a lot for the tip! That is just what I was missing (for 5.38). Previous Comments: ------------------------------------------------------------------------ [2011-07-04 12:12:07] breck7 at gmail dot com While compiling the new PHP 5.4 release I tried using: --with-readline, --with- libedit, and --with-libedit --without-readline and always got " I cannot find readline.h" In case anyone has trouble reinstalling readline, run this: sudo apt-get install libreadline-devel I found that tricky (was trying install readline, install readline--devel, install libedit, install libedit--devel, etc.). I figured I'd post this since this is the first Google result for "I cannot find readline.h" ------------------------------------------------------------------------ [2009-12-13 17:07:20] felipe@php.net This bug has been fixed in SVN.

Accordingly, configure claims that libedit is not properly installed, when it is. I've written a straightforward patch to fix this: http://spot.fedorapeople.org/php-5.3.0-libedit.patch It is also possible to use pkgconfig to ask libedit for its include flags (and cflags), which would return "-I/usr/include/editline", but as that was slightly more intrusive, I did not go down that road. In addition, on a system where readline-devel and libedit-devel are both installed, the existing code checking for /usr/include/readline-devel will cause a false positive when checking for libedit, and will end up doing a compile with readline's headers and libedit's library. Reproduce code: --------------- ./configure --without-readline --with-libedit Expected result: ---------------- checking for libedit readline replacement... yes checking for readline in -ledit... yes Actual result: -------------- checking for libedit readline replacement... yes configure: error: Please reinstall libedit - I cannot find readline.h ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=50209&edit=1
