I'm installing postgresql 8.4 in Debian, put program testlibpq.c from http://www.postgresql.org/docs/9.0/interactive/libpq-example.html to directory which have file libpq-fe.h, but after compilation gcc write me
testlibpq.c:(.text+0x4a): undefined reference to `PQconnectdb'
testlibpq.c:(.text+0x5a): undefined reference to `PQstatus'

... e.t.c. What I must suppose to do to correct work?
Looks like you're not linking the PostgreSQL library. You should be compiling testlibpq.c with something like this:
gcc -o testlibpq testlibpq.c -lpq
The -lpq tells the linker to link against the PostgreSQL library and that's where PQconnectdb and friends come from.
You may need to tell the compiler where to find the libraries and headers as well, if so then something like this should sort that out:
gcc -o testlibpq -I$(pg_config --includedir) -L$(pg_config --libdir) -o testlibpq $(pg_config --libs)

My OS is ubuntu 14.04 32bit and my source program test.c is :
#include <stdio.h>
int main(int argc, char *argv[])
{
printf("test.");
return;
}
I compile it with command :
gcc -S test.c
which output as a test.s file. I assemble it with command :
as -o test.o test.s
then I want to link it with c standard library statically. I searched for libc.a file , located it at /usr/lib/i386-linux-gnu/libc.a. so I tried to link it with command:
ld test.o /usr/lib/i386-linux-gnu/libc.a
but comes out with a lot of error message:

My question is, why these error messages ? I'm trying to learn how the compiling system works, so instead of knowing how to solve this problem I 'm more desiring to know how it comes this way. It seems that the static C library depends on other libraries, why and what are those libraries ?
EDIT:
I'm doing this because I want to know how things work so I'd rather avoid the gcc script.
You also need crt0 startup object files (in addition of static libc.a), which notably are defining the _start entry point (in your ELF executable) and contain ABI specific (prologue and epilog) code to call your main (and finally process atexit(3) registered handlers and stdio flushing). The low-level libgcc is also needed. Details are complex and implementation specific. To understand them, compile your test code as
gcc -v -static test.c -o mytest
(avoid calling an executable test because it would collide with /usr/bin/test or with the builtin of your shell)
In practice, better at least link with gcc
If you are curious, take advantage that Linux is mostly free software and study the source code (e.g. of GCC, of the C standard library, of binutils, etc...). You might find musl-libc interesting.
I'd rather avoid the gcc script
Technically, gcc is not a script but a driver program (see gcc/gcc.c in the source code of GCC). But it will run ld which indeed runs some linker scripts. The actual compilation is done by cc1 which is started by the gcc program.
You must also link the gcc intrinsic library. The easiest way to do this is to use the gcc front-end to compile and link with the -static option:
gcc -static -o test test.c
If you insist on compiling from assembly, you can do this:
gcc -static -o test test.s
Static linking may not be supported on your system.
EDIT: giving gcc the -v option will tell you what commands it executes.
I am trying to use Curl in C.
I visited Curl official page, and copied sample source code.
below is the link:
http://curl.haxx.se/libcurl/c/sepheaders.html
when I run this code with command "gcc test.c",
the console shows message like below.
/tmp/cc1vsivQ.o: In function `main':

I do not know how to solve this.
You don't link with the library.
When using an external library you must link with it:
$ gcc test.c -lcurl
The last option tells GCC to link (-l) with the library curl.
In addition to Joachim Pileborg's answer, it is useful to remember that gcc/g++ linking is sensitive to order and that your linked libraries must follow the things that depend upon them.
$ gcc -lcurl test.c
will fail, missing the same symbols as before. I mention this because I came to this page for forgetting this fact.
I have the same problem, but i use g++ with a make file.
This is a linker issue.
You need to add option -lcurl on the compiler and on the linker.
In my case on the make file:
CC ?= gcc
CXX ?= g++
CXXFLAGS += -I ../src/ -I ./ -DLINUX -lcurl <- compile option
LDFLAGS += -lrt -lpthread -lcurl <- linker option
Gerard
Depending how bad things are you might need an -L/somewhere in LDFLAGS to let the linker know where the libraries are. ldconfig is supposed to pick them up and find them on every boot but on a new machine it can take a little prodding, like adding a directory to your /etc/ld.so.conf.
I have been searching for a couple of hours and found several threads with the same problem and tried all their suggestions.
My curl.h is in C:\MinGW\msys\1.0\curl-7.29.0\include\curl and I've included it at compile time but for some reason gcc claims it can't find it:
gcc -o curl.exe curl.c -IC:/MinGW/msys/1.0/local/ -IC:/MinGW/msys/1.0/curl-7.29.0/lib/.libs/ -IC:/MinGW/msys/1.0/curl-7.29.0/include/curl -IC:/MinGW/msys/1.0/OpenSSL-Win32/ -lcurl -lws2_32
and the result:
curl.c:4:32: fatal error: curl/curl.h: No such file or directory
UPDATE: (With the suggestion from H2CO3)
$ gcc -o curl.exe curl.c -IC:/MinGW/msys/1.0/local -IC:/MinGW/msys/1.0/curl-7.29.0/lib/.libs/ -IC:/MinGW/msys/1.0/curl-7.29.0/include/ -IC:/MinGW/msys/1.0/OpenSSL-Win32/include/ -lws2_32

If I try to compile with -lcurl it says ..... ld.exe: cannot find -lcurl is this because it can't find the dll?
You're including <curl/curl.h>, and not <curl.h>. So you have to tell the compiler to look for header files in the include directory, and not in include/curl:
gcc -IC:\MinGW\msys\1.0\curl-7.29.0\include etc. etc.
This might be beyond the scope of what you're doing, but, I found it best to install a version of cURL(libcurl) into the MinGW/MSYS environment. After installed, any program can be compiled to use it with the typical <curl/curl.h> and -lcurl conventions since it's installed where GCC would expect it. I documented my process here.
When i am trying to compile a C code which uses openssl 'crypto' library functions with comand line -lcrypto with gcc 4.4.3 it gives an error
`#ubu:$ gcc -ggdb aes_m.c -Werror -Wall -I /usr/local/ssl/include/ -lcrypto -o aes
/usr/bin/ld: cannot find -lcrypto
collect2: ld returned 1 exit status`
what can be the reason for this??
I have already gone through this discussion ld cannot find an existing library but that does not help.
locate command results in

Many thanks
Add -L /usr/local/ssl/lib/ into the GCC command line, before the -lcrypto. Since you are building against the OpenSSL headers under /usr/local/ssl, you also need to link against the actual library under the same prefix (even though you only appear to have a static one installed there, that may or may not be your intention; you may need to properly reinstall your OpenSSL built from source).
(edit) To fix the dlopen() and friends not being found by the linker, add -ldl into the GCC command line. -ldl tells the linker to also link against libdl.so, which is the shared library containing dlopen(), dlsym(), dlclose() etc.; these functions are used by OpenSSL internally and thus, -ldl is an indirect dependency when using -lcrypto (on Linux). Because you are linking to a static version of libcrypto, you need to explicitly link against all indirect dependencies.
If you are not familiar with linking to the proper libraries, I'd suggest you use OpenSSL as installed from your Operating System package manager; it might save you some trouble.
This might be relevant for people who tried to build their own openssl from source and then use it to compile other programs (in my case Git)
During configuration of openssl, add 'shared' option:
./config shared
This will create the required shared library libcrypto.so. You'll find more in the INSTALL file.
Also, if you run into this error during 'make'
"....can not be used when making a shared object
recompile with -fPIC
./config shared -fPIC
I'm having some problems statically linking ncurses to one of my programs
Here's a really simple sample program:
#include<ncurses.h>
int main(){
initscr();
printw("Hello world\n");
refresh();
getch();
endwin();
return 0;
}
When I compile it with
gcc -static -lncurses hello_curses.c -o curses
I get these errors:
/tmp/ccwHJ6o1.o: In function `main':
curses_hello.c:(.text+0x5): undefined reference to `initscr'
curses_hello.c:(.text+0x14): undefined reference to `printw'

curses_hello.c:(.text+0x2c): undefined reference to `wgetch'
curses_hello.c:(.text+0x31): undefined reference to `endwin'
collect2: ld returned 1 exit status
I'm a little confused why this isn't working. What am I missing here?
You need to pass -l options at the end of the command line:
gcc -static hello_curses.c -o curses -lncurses
When the compiler encounters -lfoo, it links in all the symbols from foo that have been requested by a previous file. If you put -lfoo at the beginning, no symbol has been requested yet, so no symbol gets linked.
Edit:
I think the real problem is that you need to specify your -l option at the end of the command. I just tried it the way you had it and reproduced your error. If I put -l:libncurses.a at the end of the line then it works. All without the -static option BTW.
I think what is happening is that you have a dynamic library for ncurses but you have used the -static option which means to not use any dynamic libraries. I suspect you do not actually have a static version of the ncurses library i.e. one ending with a .a suffix.
If you want to link with the static version (.a) of ncurses rather than the dynamic version (.so) then temporarily remove the symlink for libncurses.so so that the linker picks up the .a file instead. Alternatively copy the .a file somewhere else and add that to an earlier search path.
Alternatively if your linker supports it (eg. ld) then you could specify -l:libncurses.a instead of -lncurses.
I just spent a few hours on an ARM processor, trying to get it to work, as the accepted answer didn't work for me.
Here are my findings:
Apparently
gcc -static hello_curses.c -o curses -lncurses
works on an x64 processor, but not on an ARM processor.
When I tried with the above line, I still got all the "undefined reference errors" (and a lot more) of the OP.
You need to also link against libtinfo.a, and note that sequence matters.
This is the correct command line that works:
gcc -static hello_curses.c -o curses -lncurses -ltinfo
If you mix up the sequence, then it won't work...
gcc -static hello_curses.c -o curses -ltinfo -lncurses
undefined reference to `unctrl'
Of course this also works if you use the :lib syntax
This compiles
gcc -static hello_curses.c -o curses -l:libncursesw.a -l:libtinfo.a
This does not compile
gcc -static hello_curses.c -o curses -l:libtinfo.a -l:libncursesw.a
Oh how I like gcc...
