Edit report at https://bugs.php.net/bug.php?id=55634&edit=1 ID: 55634 Updated by: cmb@php.net Reported by: cweiske@php.net Summary: ./configure does not fail if invalid option is used Status: Open Type: Bug Package: *Configuration Issues PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: On Windows, configure bails out early if an unknown option is passed, what I find rather helpful. Previous Comments: ------------------------------------------------------------------------ [2013-08-02 11:57:32] mike@php.net It's not always been like that, there have been times where configure ignored unknown arguments silently. So, I'd say, we're open for improvements. ------------------------------------------------------------------------ [2011-09-22 19:09:58] pajoye@php.net well, I do consider it as a bug fix. ------------------------------------------------------------------------ [2011-09-22 19:07:27] ashnazg@php.net Perhaps a BC compromise here would be to at least *also* echo to stderr, while leaving the existing echo to stdout in place? ------------------------------------------------------------------------ [2011-09-07 22:28:17] fa@php.net I'm not saying this behaviour is wrong or right, I've been bitten by this already myself, but I do think that could be considered a BC break, as I remember it always being like that, although I'm only 100% sure on 5.2+ ------------------------------------------------------------------------ [2011-09-07 13:17:55] cweiske@php.net Description: ------------ When using ./configure --with-foo, configure tells me at the end: > Notice: Following unknown configure options were used: > --with-foo There are two problems: - This problem is echoed to stdout, not stderr where capturing it would be possible - The exit code is still 0, although I clearly issued a wrong option. In the end I cannot figure out if the configure run was *fully* successful. Expected result: ---------------- 1. config option errors echoed to stderr 2. exit code of configure script != 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55634&edit=1
