That would be:
LD_LIBRARY_PATH was generally meant for runtime not compile time - that is up to you with -L. Using an oddball version of a generally standard library is the path to future problems. I would link against the archive (.a) rather than the .so -- if you plan to move it to other boxes.
Dear all, I have downloaded the latest version of gcc --- gcc-3.3.1.tar.gz from gnu.org. My Linux distribution is Mandrake 9.0. This was how I installed it:

passwrd:
mkdir /usr/local/src
cd /usr/local/src
gunzip /tmp/gcc-3.3.1.tar.gz #where I downloaded the file

Hi,
I'm confused about the GCC & Linking process could somebody please briefly explain?
I have GCC 3.4.6 installed from SunFreeware. Reading the narrative alongside the package states "It was compiled to use the SUN assembler and loader usually in /usr/ccs/bin if the SUNW developer packages... (1 Reply)

Hi,
I would like "grep" command to search ALL files in current directory in the order of their modified/created date. How can i do this?
e.g., if 3 files contain the pattern i am searching for, i need the output of "grep" to be in the order such that old file search result should come first.... (6 Replies)
Hi,
I do not use the default linker, and instead us another one and pass this argument -Wl,--dynamic-linker=<path to linker> to gcc when compiling. However, what happens if the linker is not under /lib and /lib64 and I am not able to create a symlink to the linker in /lib or /lib64 due to no... (2 Replies)
Hai,
I have two (Pgm1.c and Pgm2.c) simple programs, which is compiled using gcc. Now we have two exe's (Pgm1 and Pgm2). When i executed the nm Pgm1 and nm Pgm2, in the listed symbols the address of main is same for both programs (08048344 T main) at run time also.
Doubt:

I would like to compile a binary that doesnot depend on LD_LIBRARY_PATH as this binary will be setuid to owner and used by other users and since setuid doesnot support LD_LIBRARY_PATH making it independent of LD_LIBRARY_PATH would be great.

environment.d
ENVIRONMENT.D(5) environment.d ENVIRONMENT.D(5)NAME
environment.d - Definition of user session environment
SYNOPSIS
~/.config/environment.d/*.conf
/etc/environment.d/*.conf
/run/environment.d/*.conf
/usr/lib/environment.d/*.conf
/etc/environment
DESCRIPTION
The environment.d directories contain a list of "global" environment variable assignments for the user environment. systemd-environment-d-
generator(8) parses them and updates the environment exported by the systemd user instance to the services it starts.
It is recommended to use numerical prefixes for file names to simplify ordering.
For backwards compatibility, a symlink to /etc/environment is installed, so this file is also parsed.
CONFIGURATION DIRECTORIES AND PRECEDENCE
Configuration files are read from directories in /etc/, /run/, and /lib/, in order of precedence. Each configuration file in these
configuration directories shall be named in the style of filename.conf. Files in /etc/ override files with the same name in /run/ and
/lib/. Files in /run/ override files with the same name in /lib/.
Packages should install their configuration files in /lib/. Files in /etc/ are reserved for the local administrator, who may use this logic
to override the configuration files installed by vendor packages. All configuration files are sorted by their filename in lexicographic
order, regardless of which of the directories they reside in. If multiple files specify the same option, the entry in the file with the
lexicographically latest name will take precedence. It is recommended to prefix all filenames with a two-digit number and a dash, to
simplify the ordering of the files.
If the administrator wants to disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null
in the configuration directory in /etc/, with the same filename as the vendor configuration file. If the vendor configuration file is
included in the initrd image, the image has to be regenerated.
CONFIGURATION FORMAT
The configuration files contain a list of "KEY=VALUE" environment variable assignments, separated by newlines. The right hand side of these
assignments may reference previously defined environment variables, using the "${OTHER_KEY}" and "$OTHER_KEY" format. It is also possible
to use "${FOO:-DEFAULT_VALUE}" to expand in the same way as "${FOO}" unless the expansion would be empty, in which case it expands to
DEFAULT_VALUE, and use "${FOO:+ALTERNATE_VALUE}" to expand to ALTERNATE_VALUE as long as "${FOO}" would have expanded to a non-empty value.
No other elements of shell syntax are supported.
Each KEY must be a valid variable name. Empty lines and lines beginning with the comment character "#" are ignored.
Example
Example 1. Setup environment to allow access to a program installed in /opt/foo
/etc/environment.d/60-foo.conf:
FOO_DEBUG=force-software-gl,log-verbose
PATH=/opt/foo/bin:$PATH
LD_LIBRARY_PATH=/opt/foo/lib${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
XDG_DATA_DIRS=/opt/foo/share:${XDG_DATA_DIRS:-/usr/local/share/:/usr/share/}
