Re: Patches wrt to Tru64

[ANEESH KUMAR .K.V]

Hai ,

I am sorry . I think i attached a wrong file while mailing .  I will list 
the exact thing i did .

1) The flag used for passing the linker options through a compiler  is -Wl
2) The latest patch i send ( ltc-cxx.sh) is for enabling the -export-symbols 
option for compaq c++ compiler . It is no way related to the the way linker 
flags are passed . But while adding those patches to the latest code base 
from cvs i found that you  have already applied my old patch which i have 
asked to revert . I was under impression that  -WL is the correct way to 
pass the flag because -Wl is giving some compiler error when used with rpath 
. Later i checked with compaq and found that is a compiler bug and the  
correct way of passing linker flag is by using the option -Wl . That is why 
he decided to pass rpath directly not using ${wl} . I remember asking you 
not to apply the patch that chaned the way linker flags are passed through 
the compiler long back .  But now since i have send you a wrong cvs diff u 
might have got confused . Sorry for that . Any how i think this mail should 
make every thing clear . I only thing i need is

1) change -WL -> -Wl

2) Add the support for export-symbols option of the libtool for compaq c++ 
compiler .

The following lines need to be added to the file ltc-cxx.sh if u want to 
enable this option i assume u have already reverted the "WL" changed .

Sorry once again .
