gcc can't find libgcc_s.so.1

gcc can't find libgcc_s.so.1

[Paul Dubuc]

I'm having trouble building gcc (3.3.4 on Solaris 8 Sparc) so that it doesn't 
need the location of libgcc_s.so.1 in LD_LIBRARY_PATH.  I thought I could do 
this in the bootstrap step by saying

    gmake LDFLAGS="-Wl,--rpath -Wl,${GCCRUNLIBDIR}" bootstrap

or

    gmake LDFLAGS="-R${GCCRUNLIBDIR}" bootstrap

this has worked in the past when libstdc++.so developed a dependency on this 
library:

dump -Lv libstdc++.so

libstdc++.so:

   **** DYNAMIC SECTION INFORMATION ****
.dynamic:
[INDEX] Tag         Value
[1]     NEEDED          libm.so.1
[2]     NEEDED          libgcc_s.so.1
[3]     NEEDED          libc.so.1
[4]     SONAME          libstdc++.so.5
[5]     RPATH           /volws/pmd25/ldatae/gnu/gcc-3.3.4/lib
[6]     INIT            0x26468
[7]     FINI            0x5c970
[8]     HASH            0x94
...

The RPATH is the location of libgcc_s.so.1.  Now, I notice that the gcc and g++ 
executables also have this dependency:

dump -Lv g++

g++:

   **** DYNAMIC SECTION INFORMATION ****
.dynamic:
[INDEX] Tag         Value
[1]     NEEDED          libgcc_s.so.1
[2]     NEEDED          libc.so.1
[3]     INIT            0x11468
[4]     FINI            0x25778
[5]     HASH            0x100e8


This wasn't the case in 3.3.1
How do I run gmake bootstrap to get the RPATH into the executable so I don't get

ld.so.1: ./g++: fatal: libgcc_s.so.1: open failed: No such file or directory
Killed

when I run the compiler and so I don't have to set LD_LIBRARY_PATH?

Any help would be appreciated.

I think I've figured it out.  For any one else who might be interested, set 
BOOT_LDFLAGS to the same value as LDFLAGS:

     gmake \
          LDFLAGS="-Wl,--rpath -Wl,${GCCRUNLIBDIR}" \
          BOOT_LDFLAGS="-Wl,--rpath -Wl,${GCCRUNLIBDIR}" \
          bootstrap
