I tried to compile the sources to ocaml 3.00 on my newly installed
redhat 7.0 box.

Yep. Has to do with new glibc. Here is an unofficial patch (to config.h)
Also, if you attempt to compile ocamltk416 you will hit another configuration
problem; attached is also a new configure.in for ocamltk416

dnl This file is an input file used by the GNU "autoconf" program to
dnl generate the file "configure", which in turn produces the files
dnl "Makefile.config" and "Makefile.camltk".
dnl If you don't have autoconf installed, simply use the "configure"
dnl script.
dnl Usage:
dnl $ autoconf configure.in > configure
dnl edit site.config
dnl $ ./configure -with-config=site.config
dnl NOTE: autoconf 2.4 CHOKES on this. Use a newer version (e.g 2.7).

dnl This is the file that must exist in srcdir
AC_INIT(Widgets.src)

dnl Rather use gcc
AC_PROG_CC
AC_HAVE_HEADERS(unistd.h limits.h)

dnl Defaults for variables, overriden in site.config
LIBEXT=
INSTALLDIR='$(LIBDIR)/camltk'

dnl We need locations in the first place
AC_ARG_WITH(config,
[ --with-config=Site specific locations of various software. Check the INSTALL instructions],
if test -f $withval; then
SITECFG=$withval
. $withval
else
AC_MSG_ERROR($withval does not exist)
fi,
AC_MSG_ERROR(
You must provide a file giving the location of various software using the option --with-config=file. Check the INSTALL instructions))

if test -z "$OCAMLLIBDIR"; then
AC_MSG_ERROR("OCAMLLIBDIR is still undefined. Edit $SITECFG")
fi

dnl builtin rule for X
AC_PATH_XTRA
WITH_X="$X_LIBS $X_PRE_LIBS -lX11 $X_EXTRA_LIBS"

dnl builtin rule for ranlib
AC_PROG_RANLIB

dnl As soon as we use this, we must have install-sh available. Damn.
dnl AC_CANONICAL_HOST

LIBS="-lm"

We probably need more

AC_CHECK_LIB(dl, dlopen, LIBS="-ldl $LIBS")

Check for Tcl7.5(7.6) and Tk4.1(4.2)

AC_MSG_CHECKING(Tcl and Tk includes and libraries)

AC_CHECK_HEADERS(tcl.h,,
AC_MSG_ERROR(Can't find tcl.h. Check the CPPFLAGS variable in $SITECFG))

dnl We use Tcl_GetFile to be sure to get version >= 7.5
dnl But for 8.0, it doesn't work anymore. Use Tcl_GetObjResult.
dnl This still fails if tcl.so and tk.so are for 8.0.
dnl use X_EXTRA_LIBS to get -lnsl and -lsocket on Solaris

Thanks. That fixed my problem.

Subject: Re: Compiling Ocaml in RedHat 7.0 (#2594)

I tried to compile the sources to ocaml 3.00 on my newly installed
redhat 7.0 box. I used the standard configuration (from
./configure), and
make
world
produces the error:
[...]
/usr/include/string.h:245: conflicting types for memmove' /usr/include/string.h:42: previous declaration of memmove'

This is a bug in O'Caml 3.00. It will be fixed in the next release.

In the meantime, you can work around this bug by removing
the two lines after "#ifdef HAS_MEMMOVE" from the file
byterun/config.h. These are lines 59 and 60, and they look like this:

#undef bcopy
#define bcopy(src,dst,len) memmove((dst), (src), (len))

Thanks for the report,
