"No regcomp library function" error during configure

[Guillaume BRAUX-2]

Hello,

I am trying to build SquidGuard on windows with MinGW/MSYS but I am getting
this error when trying to configure :

$ ./configure --prefix=/mingw
.
.
checking regex.h usability... yes
checking regex.h presence... yes
checking for regcomp... no
configure: error: No regcomp library function.

(somebody in the mailing list sent a message with the same problem last
year, but nobody was able to find a simple solution
--> 2007-11-30 [1] [Mingw-users] Compiling SquidGuard - missing regcomp)

Please also note that I can read in the SquidGuard website : "native Windows
support using the MSYS+MinGW build environment".
So it means that somebody have already be able to have it compiling !

----------------------------------------------------------------------------
---------------------------------


My build environnement is up and working (I made several builds of other
programs before without any problems).

As the problem seems to come from regex libraries missing , I downloaded
mingw-libgnurx-2.5.1 (dev and bin) from mingw sourceforge repository
http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=73286&
release_id=140957.

I copied the files :
libgnurx-0.dll in c:/MinGW/bin
libgnurx.dll.a and libregex.a in c:/MinGW/lib
regex.h in c:/MinGW/include

But it is still not working (regex.h check goes to "yes" in the configure
process, but still the regcomp error)...

I also notice the same error in another program I tried to
configure/compile, also dealing with regex ...
In conclusion, I cannot compile any program which got a regcomp check in
configure !

Maybe I have not installed/copied the regex library well, as it seems to be
a shared lib ...

Please help !
Thanks,

Hello,

Regcomp cames on gnulib. Maybe you should download the last version
and include it using LIBFLAGS and LDFLAGS.

MinGW doesn't provide regex by default, but it is provided as a User
Contributed add-on.  You've clearly installed a regex package from
somewhere, since you have the regex.h header; was this our package,
or from some other source?  If from another source, then please try
our package; if it was ours, then please read on...

Accompanying the regex.h header, we also provide libregex.a, which
definitely *does* provide regcomp(), (as an import stub for an actual
function implementation in libgnurx-0.dll).  Please check config.log
for the detailed reason for failure of the library test; did the
configure test correctly specify the library to check?  If not, then
maybe you need to provide a `--with-regex=...' or similar option to
configure, (try `configure --help' for syntax), or you may need to
add `-lregex' to LDFLAGS when you run configure; if yes, then is the
library correctly installed, in an appropriate path?

Without details of the actual reason for failure, as may be found in
config.log, there really isn't much more advice I can offer.

Keith.

Michel,

Two issues here:

1) Please DO NOT top post.  (If you don't know what this means, or why
we find it so annoying, then please read http://tinyurl.com/ev66).

2) Please acquaint yourself with the packages WE offer, before sending
users to some other project.  While gnulib may offer a suitable regex
implementation, WE have OUR OWN, which is known to work with MinGW,
and which most definitely DOES provide regcomp().  This should ALWAYS
be preferred over any foreign implementation.

Sorry about that Keith, and thanks to send me this useful link.

I will try to learn more about this. Thanks again.
