GCC bug with strftime
Hi All, It's been about eight months since I last posted to this list - hope everyone is doing well... I recently discovered a bug in strftime(). I downloaded a very recent copy of cygwin and tried again, but it's still there. So, I'd like to report it. I sent mail to the gcc-bugs list but nobody there seems to care, so I thought I'd mention it here. The problem is that this call fails to return an hour: strftime(IT,key,%m/%d/%y %l:%M %p, brokentime); The l% is supposed to represent a _space_ padded hour, as documented here: http://www.gnu.org/manual/glibc-2.0.6/html_chapter/libc_17.html#SEC302 I wrote a test program to illustrate the problem - call it a bug script: $ ./strftime This program illustrates a bug with strftime as it fails to return the hour. We are trying to use these flags: '%m/%d/%y %l:%M %p' strftime returned: 01/09/03 :26 PM The proper result: 01/09/03 3:26 PM $ My workaround (in the bug script) gets the hour as two digits and then tosses a leading zero... What a pain. -shrug- I don't know how to check what version of the library I have, but I have the following gcc compilers installed (as reported by cygcheck -s): gcc 3.2-3 gcc-mingw 20020817-4 gcc22.95.3-10 Please direct me on how I can get this information to someone who knows what to do with it!

Are you sure that you are not passing a 'el' instead of a capital 'eye' it is real hard to differentiate in some typefaces note: python just calls the underlying 'C' strftime() implementation HTH Norman Thanks for the thought, Norman. The answer is yes, I have checked. The code works in my various RedHat environments and has been for a long time. Also capital I is not what I need; As your example illustrated, it returns a zero padded two digit hour, but what I want/need is a non-padded hour, two or one digit, depending. The reason I really care is because there are two programs that have to talk to one another, one written in C and the other in Java. It nearly doesn't matter which is which is which, they just have to agree on the format. All was fine until I compiled the code on my cygwin installation. -shrug- Richard -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
