sparc-sun-solaris2.8-g++: collect-ing wrong libraries (32/64 bit)?

sparc-sun-solaris2.8-g++: collect-ing wrong libraries (32/64 bit)?

[Daniel Franke]

Hi all,
I try to figure out how to compile the code below as 64bit executable:

-- foo.cpp --
int main () {
  return 0;
}
--
The code compiles:
$> g++ -m64 -O2 -g foo.cpp

and:
$> file a.out
a.out:          ELF 64-bit MSB executable SPARCV9 Version 1, dynamically 
linked, not stripped

tells me that I got what I asked for, but:
$> ldd a.out
        libstdc++.so.6 =>        /usr/local/lib/libstdc++.so.6  - wrong ELF 
class: ELFCLASS32
        libm.so.1 =>     /usr/lib/64/libm.so.1
        libgcc_s.so.1 =>         /usr/local/lib/libgcc_s.so.1  - wrong ELF 
class: ELFCLASS32
        libc.so.1 =>     /usr/lib/64/libc.so.1
        libdl.so.1 =>    /usr/lib/64/libdl.so.1
        /usr/platform/SUNW,Sun-Blade-1000/lib/sparcv9/libc_psr.so.1

As you can see, the linker (sun ld) seems to include the 32bit versions of 
libstd++ and libgcc_s, instead of their 64bit companions - which are located 
in '/usr/local/lib/sparcv9/'.

Verbose output (see below) shows that
-L/usr/local/lib/gcc/sparc-sun-solaris2.8/3.4.1/../../../sparcv9
actually _is_ included in the library search path.

What's wrong here? Do I miss something? Compiler flags? Linker flags? A bug in 
g++/collect2? Something completely different? 

Thanks in advance for any hints :)

Oh my goddess!

Lyle, thank you very much. I hadn't had '/usr/local/lib/sparcv9' in my 
LD_LIBRARY_PATH. I somehow thought the libs should be found anyway (magic?).
I knew it must be something really stupid!

Thanks a lot!

RE: sparc-sun-solaris2.8-g++: collect-ing wrong libraries (32/64 bit)?

[lrtaylor]

GCC's 64-bit libraries are in a different directory.  For example, try looking under /usr/local/lib for a directory named sparcv9 or something.  Or, if GCC's libraries are installed into a GCC-specific sub directory somewhere, try looking there.  You'll then need to modify your LD_LIBRARY_PATH to look there before /usr/local/lib.

Thanks,
Lyle
