How to force preferred library search path for Apache


Can someone tell me how to force a default path of "/usr/local/" to a new Apache installation.

I just install everything new and keep getting the error message:

libtool: link: cannot find the library `/usr/lib/libgdbm.la'

All Perl and all the libraries and packages have been installed to /usr/local. The libgdbm.la file is in /usr/local/lib.

The system is a brand new hard drive with a new installation of Fedora Core 8. I prefer not to bother with /usr/lib for my custom installations because I don't want to interfere with the already configuration of things such as sendmail and all the other distro defaults.

I have installed the following packages and set them all to point to /usr/local:

perl-5.8.8.tar.gz: /usr/local
httpd-2.2.8.tar.bz2: /usr/local
libtool-1.5.26.tar.gz: /usr/local
gdbm-1.8.3.tar.gz: /usr/local

I set the following link library flag:

export LDFLAGS="-L/usr/local/lib"

I cleaned and attempted to compile apache as such:

make distclean
./configure --libdir=/usr/local/lib
make

The configure completes without errors. The "make" errors with:

libtool: link: cannot find the library `/usr/lib/libgdbm.la'

Is there something else that I can do to force apache to forget /usr/lib and use /usr/local/lib instead?

Thanks in advance for anyone with advice. Is there something hard coded about apache that makes it totally depended on looking at /usr/lib?

You may need to set LD_RUN_PATH to /usr/local/lib when you are building Apache. You can also set LD_LIBRARY_PATH after you have built something if the libraries are not in the place it is looking for them to point to a new location. For more info read:

Since he'll be using /usr/local anyway, wouldn't it be easier to just add the path to /etc/ld.so.conf?


Larry James, since you use Fedora (the "Core" part was dropped around 6 IIRC), why not install Apache as RPM? And if you need a custom Apache package maybe first look at compatible repo's? You could also build a package by tweaking the .spec file from the previous httpd-2.2.*.src.rpm. Finally you can install packages in a different path and still have RPMDB take care of things using the "--relocate" switch.

I was assuming that he didn't want other things looking at that lib directory for libraries, only the things he was playing with. If you add a file to /etc/ld.so.conf.d pointing at that path, won't it make everything look at that path for libraries?

Sure but it's not like adding it will fsck things up, only in rare occasions like if you have multiple versions of libraries installed.

If you choose to add /usr/local/lib to /etc/ld.so.conf you should also run ldconfig as well.

Thanks to everybody for your input. I had already done many of the suggestions. I meant to mention each one of them, but it seems that I left some off. Iíve since studied the suggested links and other suggestions and will present the results.

Thanks, Forrest, I did both and studied the URL in detail. Iím still getting the same when I run the ďmakeĒ.

Thanks, unSpawn. I forgot to mention that I have the following in my /etc/ld.so.conf file. I also had run ldconfig with many different parameters.

----------------------------
include ld.so.conf.d/*.conf
/usr/local/lib

Apache is already installed on the new Fedora 8 machine. I have a server that has been running since 1993 (starting out with SCO Unix and upgraded numerous time, through Slackware, Red Had, with the last time being Fedora 6 about 4 years ago). My hard drive is dying on the machine. Iím building a fresh machine and would prefer to work with the tar ball as I always have in the past. It itís resolved that itís no longer possible, this is something Iíll learn. But if it is, I hope to be able to do it.

I have many custom utilities that I have build on my old machine, and I have always had full control. Maybe I could do the same with the RPM shipped with Fedora. But I would consider it a benefit overall if I could take the packages, configure, compile and build them myself. I feel it would help in the long run when I have to troubleshoot.

Even though Iíve been working with this dilemma, I somehow think itís something simple that Iím missing. At present it seems like a lot of us are missing what it is that Apache is doing, because as I mentioned, I have done most of the things suggested. Iíve done a lot of reading in the process of trying to figure out the problem.

Again, though I mention I have a number of custom packages I wish to install, at present I havenít installed anything. Iíve only tried to compile the distribution httpd-2.2.8 tarball the way itís distributed by pointing the compiler to use the library from a preferred path, /usr/local/lib. They are failing right out of the box.

Thanks again, Forrest. I donít mind other things seeing the packages I install. I just hoped not to contaminate the default /usr/lib with my custom applications.

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

I have every suggestion mention so far in this thread set.

The /etc/ld.so.conf file:
/usr/local/lib

The environment variables:
export LD_LIBRARY_PATH=/usr/local/lib
export LD_RUN_PATH=/usr/local/lib
export LDFLAGS="-L/usr/local/libĒ

The libgdbm.la exists in the /usr/local/lib directory. I tested a symbolic link in the /usr/lib file to that file and the compile succeeds. Iím going to immediately attempt to continue building the new system with the links. I have many applications that I will be bringing over from the old system. If it were possible to work out why specifying a directory path fails it might solve other issues that I havenít experienced yet.

I have two Apache directories that Iím testing in an attempt to solve this problem. Thereís the /usr/local/apache that Iím using in this immediately workaround (linking the libraries one by one) and /usr/local/apache2 (which is a virgin tarball that Iím trying to accomplishing having it success in compiling with the specified link.

I appreciate all the quick input and suggestions. Itís been a long time since I asked questions on LQ. The way the responses always come in is and always has been phenomenon. Thank you again to everyone for your input.

I would like to thank everyone visiting this thread and pondering the problem. It turns out it was an SELinux issue. All the set paths are now recognized and configurable.
