Hi all
I have been struggling with this since quite a while now. This is what I have found.
Some changes in libtool.m4 have been made to support Intel compiler.Thes are like
..
..
icpc)
# Intel C++
_LT_AC_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'
_LT_AC_TAGVAR(lt_prog_compiler_pic, $1)='-KPIC'
_LT_AC_TAGVAR(lt_prog_compiler_static, $1)='-static'
..
..
linux*)
case $cc_basename in
icc|ecc)
_LT_AC_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'
_LT_AC_TAGVAR(lt_prog_compiler_pic, $1)='-KPIC'
_LT_AC_TAGVAR(lt_prog_compiler_static, $1)='-static'
;;
..
..
WHICH means that libtool must now supoort both icc and icpc . BUT when I am running my
configure script by setting the following environment variables
CC=icc
CXX=icpc
LD=ld
PATH and LD_LIBRARY_PATH accordingly set to find the above
IT SEEMS that the above mentioned changes in libtool.m4 are never incorporated in my
case. Either this is a bug or may be I am making a blunder .Of these two options
latter is a strong possibility because its just been 10 days since I have started
with linux . :-)
Coming back to the point
I run
./bootstrap DOESNT COMPLAIN WITH ANY ERRORS
./configure --prefix=/home/me/usr DOESNT COMPLAIN WITH ANY ERRORS
make GIVES THE FOLLOWING ERROR
...
...
configure: creating ./config.status
/bin/sh ./libtool --mode=compile icc -DHAVE_CONFIG_H -I. -I. -I. -g -c -o lt
dl.lo `test -f 'ltdl.c' || echo './'`ltdl.c
mkdir .libs
icc -DHAVE_CONFIG_H -I. -I. -I. -g -c ltdl.c -DPIC -o .libs/ltdl.o
icc -DHAVE_CONFIG_H -I. -I. -I. -g -c ltdl.c -o ltdl.o >/dev/null 2>&1
/bin/sh ./libtool --mode=link icc -g -o libltdl.la -rpath /home/himanshu/usr/
/lib -no-undefined -version-info 4:0:1 ltdl.lo -ldl
icc -shared .libs/ltdl.o -ldl -lc -soname libltdl.so.3 -o .libs/libltdl.so.3.
1.0
icc: Command line warning: ignoring unknown option '-soname'
ld: cannot open libltdl.so.3: No such file or directory
make[2]: *** [libltdl.la] Error 1
make[2]: Target `all-am' not remade because of errors.
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1
make: Target `all' not remade because of errors.
WHEN I SAY
ls
I CAN SEE libtool having already been made
AND WHEN I SAY
./libtool --config
I GET
..
..
# Libtool was configured on host blrkecxxx:
# Shell to use when invoking shell scripts.
SHELL="/bin/sh"
# Whether or not to build shared libraries.
build_libtool_libs=yes
# Whether or not to build static libraries.
build_old_libs=yes
# Whether or not to add -lc for building shared libraries.
build_libtool_need_lc=yes
# A C compiler.
LTCC="icc"
# A language-specific compiler.
CC="icc"
# Is the compiler the GNU C compiler?
with_gcc=
# The linker used to build libraries.
LD="ld"
# How to pass a linker flag through the compiler.
wl=""
# Additional compiler flags for building library objects.
pic_flag=" -DPIC"
pic_mode=default
..
..
NOW WHAT I THINK IS THAT SINCE LIBTOOL FOR ICC IS NOT BEING TAUGHT HOW TO handle
PIC,and linker flag(wl="Wl,") and this is why the make command is failing due to
inability of icc to pass -soname option to linker.
WHICH MEANS that the abovementioned piece of code-patch in libtool.m4 is not being
accessed.
MY QUESTION IS WHY? IS IT A PROBLEM WITH THW WAY I AM DOING THINGS ???????
LOOKING FOR HELP

No, support for icc is broken, the problem has been reported
to no avail, and the email address of the person who did the
icc port bounces. See
http://mail.gnu.org/archive/html/libtool/2003-03/msg00000.html
for more information (same problem with the current HEAD).
