static lib problem

static lib problem

[De Leeuw Guy]

Hello,
I'm a new user of gcc and I have a little problem when I try to link
with a static library

Building library :
==================
gcc -DCOMP_OS=3 -o Linux/gdtsf.o -I/usr/include -I/usr/local/include 
-I../../hdr -c ../../srcLassie/gdtsf.c
gcc -DCOMP_OS=3 -o Linux/gdtypes.o -I/usr/include -I/usr/local/include 
-I../../hdr -c ../../srcLassie/gdtypes.c
ar -rs Linux/liblassiec.a Linux/*.o;


Building object :
=================
gcc -c -DCOMP_OS=3 -I/usr/include -I/usr/local/include  -I../../hdr -o
Linux/crlf.o ../../srcExe/crlf.c

Building executable :
=====================
ld -o Linux/crlf Linux/crlf.o -L/lib -L/usr/lib
-L../../libLassiec/Unix/Linux -Bstatic -llassiec -lisam -lc_nonshared

[guy@pcGDL Unix]$ ld -o Linux/crlf Linux/crlf.o -L/lib -L/usr/lib
-L../../libLassiec/Unix/Linux -Bstatic -llassiec -lisam -lc_nonshared
ld: warning: cannot find entry symbol _start; defaulting to
0000000008048094
Linux/crlf.o(.text+0x31): In function `main':
: undefined reference to `printf'
Linux/crlf.o(.text+0x41): In function `main':
: undefined reference to `printf'
...
...
...

Wich libraries are mising ?

I try also :
ld -o Linux/crlf Linux/crlf.o -L/lib -L/usr/lib
-L../../libLassiec/Unix/Linux -Bstatic -llassiec -lisam -lc_nonshared
-Bdynamic -lresolv
ld: warning: cannot find entry symbol _start; defaulting to
0000000008048310

HERE THE PROBLEM :
==================
[guy@pcGDL Unix]$ Linux/crlf
bash: Linux/crlf: No such file or directory
[guy@pcGDL Unix]$

[guy@pcGDL Unix]$ ll Linux/crlf*
-rwxr-xr-x  1 guy guy 4002 mai 25 12:41 Linux/crlf*
-rw-r--r--  1 guy guy 2720 mai 25 12:23 Linux/crlf.o
[guy@pcGDL Unix]$

[guy@pcGDL Unix]$ file Linux/crlf
Linux/crlf: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), not stripped
[guy@pcGDL Unix]$

[guy@pcGDL Unix]$ ldd Linux/crlf
/usr/bin/ldd: line 1: Linux/crlf: No such file or directory
[guy@pcGDL Unix]$

[guy@pcGDL guy]$ gcc -v

Thanks in advance for your help

Hi Guy,

Try this for Building the executable (all one line):
gcc -o Linux/crlf Linux/crlf.o
-L../../libLassiec/Unix/Linux -Wl,-Bstatic -llassiec -lisam -lc_nonshared

HTH,

Hi Guy,

 >But what is the problem ???

The problem was that you were using "ld" directly, instead of "gcc".

To see how gcc invoked ld "under the covers", do this...

gcc -v -o Linux/crlf Linux/crlf.o
-L../../libLassiec/Unix/Linux -Wl,-Bstatic -llassiec -lisam -lc_nonshared

HTH,
