On your system does gcc generate 64 bit image code by default? -m64
sets 64 bit. Most systems default to 32 bit - the ones I have anyway.
Suppose you have
gcc reads thru objects and library lists from left to right during linking. It uses implicit libraries only after the list is exhausted. So the only reason I can see from what you gave is that gcc thinks it needs to link 32bit. I do not get why you are not getting errors.
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:
su -
passwrd:
mkdir /usr/local/src
cd /usr/local/src
gunzip /tmp/gcc-3.3.1.tar.gz #where I downloaded the file

Im trying to compile some code that involves using X-Windows based functions (XDisplayName() and XOpenDisplay() ), however each time I run the compiler, Im getting a problem with the linker.
The linker says that both XDisplayName() and XOpenDisplay() are unresolved text symbols. Is there a... (1 Reply)
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)
Hello
I using CygWin and am working on project that requires whereby after I make some code changes and rebuild I have to manually copy the updated files into the install directory to test them. There is a build output directory where these files placed, but the program will not run from there.... (4 Replies)
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.

qd-config
QD-CONFIGG(1)QD-CONFIGG(1)NAME
qd-config - determine flags for compilation and linking
SYNOPSIS
qd-config [options]
DESCRIPTION
To link a Fortran-90 program with the C++ qd library, it is recommended to link with the C++ compiler used to generate the library. The
Fortran 90 interface (along with a C-style main function calling f_main) is found in the qdmod library. The qd-config script can be used
to determine which flags to pass to compile and link your programs.
OPTIONS --src Switch between source and system location.
--prefix
Output configured prefix value.
--exec-prefix
Output configured exec_prefix value.
--build-flags
Compiler options used during build.
--build-libs
Linker options used during build.
--configure-args
Configure arguments used for build.
--cxx C++ compiler.
--cflags
C++ preprocessor and compiler options.
--cxxflags
C++ compiler options.
--libs-la
C++ linker options and libtool archive location.
--libs C++ linker options.
--fc Fortran compiler.
--fcflags
Fortran compiler options.
--fclibs
Fortran linker options.
--fmainlib
C++ linker options for main program written in Fortran.
--version
Output version.
