Upgrading to R2.11.1, now Rapache won't work

[Leo]

Hi there,

I just finished uninstalling R 2.9.2 and installing 2.11.1. Upon re-
starting apache I received:
httpd: Syntax error on line 200 of /etc/httpd/conf/httpd.conf: Cannot
load /etc/httpd/modules/mod_R.so into server: libR.so: failed to map
segment from shared object: Permission denied

I just checked: libR.so is rwx for all. Perhaps this is related to
the file possibly being installed in a different location under the
new R version? Or is it that the segment to map from the new R version
is different/larger?

What to do? Do I need to reinstall rapache? The version of rapache I
had running is 1.1.7.

Thanks!

Leo

Download and install the latest release.

It's best if you do this every time you upgrade R.

Jeff, I'm still hitting a wall.

When running the make I received a message stating that the file
libdb-4.3.la was missing. As it turns out, this file is installed
with the 32-bit version of BDB (db4-devel.i386, requires bd4.i386) and
the machine where I'm trying to compile rapache is a 64-bit beast
(with 64-bit version of apache). So, I installed the 32-bit version
and now ldconfig complains: /lib/libdb-4.3.so is not a symbolic link
(this disappears when I uninstall the 32bit version of db4). Also, I
now get a different message from the make:
libtool: link: warning: `/usr/lib/gcc/x86_64-redhat-linux/
4.1.2/../../..//libdb-4.3.la' seems to be moved
libtool: link: warning: `/usr/lib/gcc/x86_64-redhat-linux/
4.1.2/../../..//libexpat.la' seems to be moved

I ignored these warnings, but still get a failed make install.

Any help/suggestions, anyone?
(I guess I can just plant a symlink to the 64-bit version of the
file... Has anyone tried that?)

Thanks
Leo

Is this redhat proper, and not whitebox or centos or whatever they
call it these days?

I just recently confirmed that rApache compiles cleanly on a CentOS 64bit dist.

Anyone?

Hello Jeff and all,

Just in case you were wondering if I tinkered with the configure
command, here it is: ./configure --with-apache2-apxs=/usr/sbin/apxs
In looking closely to the output of ./configure, I noticed:
checking for /usr/bin/apr-1-config... yes
checking for /usr/bin/apu-1-config... yes
setting APR_INCLUDES to " -I/usr/include/apr-1 "
setting APR_LTFLAGS to " /usr/lib64/libapr-1.la"
adding "/usr/lib64/libaprutil-1.la" to APR_LTFLAGS
setting APR_LIBS to " -lldap -llber -ldb-4.3 -lexpat"
adding "-lpthread" to APR_LIBS
adding "-ldl" to APR_LIBS
setting APR_LDFLAGS to " -laprutil-1 "
adding "-lapr-1" to APR_LDFLAGS
setting CPPFLAGS to " -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE"
libapreq2 Version: 2.1.0

All that seems fine, except that the libraries in:
setting APR_LIBS to " -lldap -llber -ldb-4.3 -lexpat"
are being sought in /usr/lib not in /usr/lib64

I suspect the source of the problem is in this report from the make:
grep: /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../..//libdb-4.3.la:
No such file or directory
Call this a weird installation: the gc_ shared objects are not in that
location - just the simlinks to where they really are: /lib64

Is there a flag in the ./config to specify the location of the
libdb-4.3.la file and bypass the grep?

Thanks again for any help!
Leo
