64 bit ABI issue on Solaris

[Stefan Schaeckeler <schaecsn%gmx.net@localhost>]

Hi all,

Pkgsrc on Sparc/Solaris 9. ABI=64 (set in mk.conf). Gcc 3.4.6.

Compiling my first c++ port, graphics/tiff fails in the linking phase:

As I want a 64 bit ABI, lib_stream.o seems to be in the correct format. 
.work.log shows that this is translated into

Apparently, some object files such as crti.o are taken from 
/usr/gcc/lib/gcc/sparc-sun-solaris2.9/3.4.6. That are the 32 bit files. The 64 
bit files reside under /usr/gcc/lib/gcc/sparc-sun-solaris2.9/3.4.6/sparcv9. 
Same for values-Xa.o.


Compiling a c++ hello world program shows that g++ is automatically doing the 
right thing (relevant lines shown only):

Gcc is picking up object files from either y 
/usr/gcc/lib/gcc/sparc-sun-solaris2.9/3.4.6/ or y 
/usr/gcc/lib/gcc/sparc-sun-solaris2.9/3.4.6/sparcv9. Pkgsrc is intervening 
somehow.


I didn't have such issues when compiling c programs, only.

Changing the directory names on the command line fixed the issue. So, the only 
problem with compiling tiff is the wrong directories.

What goes wrong here?

Spock:  Captain, it doesn't appear in the symbol table.
Kirk:   Then it's of external origin?
Spock:  Affirmative.
