Thanks. Depends on what you mean by "doesn't work". If you mean that you get a compile-time error: cc -o foo foo.c foo.c: In function \u2018main\u2019: foo.c:20:35: error: \u2018FNM_CASEFOLD\u2019 undeclared (first use in this function) ret = fnmatch (argv[1], argv[2], FNM_CASEFOLD); ^ foo.c:20:35: note: each undeclared identifier is reported only once for each function it appears in that's what I get too. The man page doesn't say anything about special requirements to use that function, but if you go look at fnmatch.h, you'll find: #if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 || defined _GNU_SOURCE # define FNM_FILE_NAME FNM_PATHNAME /* Preferred GNU name. */ # define FNM_LEADING_DIR (1 << 3) /* Ignore `/...' after a match. */ # define FNM_CASEFOLD(1 << 4) /* Compare without regard to case. */ # define FNM_EXTMATCH(1 << 5) /* Use ksh-like extended matching. */ #endif which indicates that those values aren't available UNLESS your program has defines matching the first line shown. I haven't bothered to check for the value of _POSIX_C_SOURCE in the absence of commandline options that change the GCC default behavior, but just defining _GNU_SOURCE is enough to make it compile: [fredex@fcshome tmp]$ cc -o foo foo.c [fredex@fcshome tmp]$ foo.c: #include #include #define _GNU_SOURCE #include int main (int argc, char ** argv) { int ret = 0; if (argc != 3) { printf ("Oops. please specify two strings to compare\n"); exit (0); } ret = fnmatch (argv[1], argv[2], FNM_CASEFOLD); printf ("fnmatch %s, %s returned %d\n", argv[1], argv[2], ret); return 0; } and running it results in: $ ./foo abc abc fnmatch abc, abc returned 0 $ ./foo abc aBc fnmatch abc, aBc returned 0 $ ./foo abc aBcz fnmatch abc, aBcz returned 1 -- --- .Fred Smith / ( /__ ,__. __ __ / __ : / // / /__) / / /__) .+' Home: fre...@fcshome.stoneham.ma.us // (__ (___ (__(_ (___ / :__ 781-438-5471 Jude 1:24,25 - ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] compile question on CentOS 7
I am trying to use the fnmatch() function in a C program and pass as the 3rd arg (options) of case insensitive search... When I use the value FNM_CASEFOLD it does not work... I'm confused on what to send to fnmatch() to do a case insensitive search. Any pointers ? Thanks. Jerry ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] konqueror vs. centos and mathematics
I'm running centos 7. Firefox spends so much time in th D state that I am trying konqueror. Displaying mathematics on wikipedia, e.g. Remez algorithm seems to be a no go. Wikipedia seems to use tex, so I installed texlive and texlive-* . Firefox hadn't needed it and it did not seem to help konqueror. My guess is that there is a bit somewhere that I need to flip, but I have no idea where it is.

Re: [CentOS] Testing software on CentOS 7
A virtual machine running CentOS with the same environment and packages installed should do the trick.

[CentOS] Testing software on CentOS 7
I need to test a new version of Geany but already have the repo version installed on all my systems. In order not to foul up my current installation, what is the suggested procedure for installing and testing this new version? I tried installing in a docker container which of course went fine but could not run it from there.
