Can't find path for shared library: libgcc_s.sl

[siba]

hi,
Sorry if this question has already answered in this forum.
I have compiled and linked a program using gcc 3.4.2 on HP 11i.
While executing the program core is dumped with message
/usr/lib/dld.sl: Can't find path for shared library: libgcc_s.sl
/usr/lib/dld.sl: No such file or directory
(coredump)

Strange part is that the path for libgcc_s.sl is present in the SHLIB_PATH and has got appropriate permissions.

My GCC version is Configured with: /scratch/njs/pkgbuild/3.3.1/hpux-11/gcc-3.4.2/configure --enable-languages=c,c++ --enable-threads=posix --disable-n
ls --with-gnu-as --without-gnu-ld --with-as=/usr/local/bin/as --with-ld=/usr/ccs/bin/ld --with-libiconv-prefix=/usr/local --prefix=/
usr/local
Thread model: posix
gcc version 3.4.2.

Please help.

thanks in advance
shiva

ll /usr/lib/dld.sl

if its there then:

SHLIB_PATH=/usr/lib:$SHLIB_PATH
export SHLIB_PATH

try again

Sorry SEP, but dld.sl is not the problem. It just can't load libgcc_s.sl. As long as you compiled with --prefix=/usr/local, your lib should be in /usr/local/lib. Is this directory in SHLIB_PATH ? Can you post your exact SHLIB_PATH and LD_LIBRARY_PATH when launching program, and also an output from ldd over your program ?

Regards,

Have you run chatr +s enable, on the exectuable ?

[Amit Agarwal_1]

By any chance do you do 'chroot' to enter a new build environemnt.

If not, then `chatr ` output would be useful to figure out the probelm.

The problem is not with my program but with libstdc++.

all my libs are not installed on /usr/local/lib but in my local profile.

ldd -v of libstdc++.sl gives
find library=/usr/lib/libc.2; required by libstdc++.sl
/usr/lib/libc.2 => /usr/lib/libc.2

find library=/usr/lib/libdld.2; required by /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2

find library=/usr/lib/libc.2; required by implicit load
/usr/lib/libc.2 => /usr/lib/libc.2

find library=/scratch/njs/pkgbuild/3.3.1/hpux-11/gcc-3.4.2-b/gcc/libgcc_s.sl; required by libstdc++.sl
/usr/lib/dld.sl: Can't find path for shared library: libgcc_s.sl
/usr/lib/dld.sl: No such file or directory

my gcc is installed in /home/user/usr/local/bin.


SHLIB_PATH=/home/user/apache/libexec:/home/user/apache:/
home/nesic/usr/local/lib:.

I had not included LD_LIBRARY_PATH earlier. Though i export the path for LD_LIBRARY_PATH as /home/user/usr/local/lib still it gives the same issue.

Please help

hi amit.
the chatr command give the foll output

any clue...

Hi some more information,
Though strange but i have verified it.

I copied libstdc++ related libraries to /usr/local/lib and my application works fine.

But in case i dont have libstdc++ related libraries and i recompile my application it fails and dumps core

/usr/lib/dld.sl: Can't find path for shared library: libgcc_s.sl
/usr/lib/dld.sl: No such file or directory
Abort(coredump)


Is there something which i am doing wrong??

[siba]

Hi,
The problem is solved when i do a chatr +s enable .

Is there any way that i can resolve it during make itself?

pa32 loader does not look at LD_LIBRARY_PATH, it only looks at SHLIB_PATH.

you can turn on SHLIB_PATH lookup at link (build) time with the linker option "+s". you can either pass it to linker directly or through compiler as "-Wl,+s" or set LDOPTS="... +s ..." (where "..." is other ld options you may have already).
