corresponding option in GCC for -brtl

corresponding option in GCC for -brtl

[Dhiraj.Nilange]

Hi,

With IBM's xlc_r compiler there is one option -brtl.

xlc_r -brtl .....

This option does the following:-

-brtl     Tells the linkage editor to accept both .so and .a library file types.

I am using gcc compiler now. I want to know what is the corresponding option in gcc to achieve 
the same thing?

After going through some webpages I tried  this:-

-Wl,-brtl

But with this I get linker error:-

/usr/bin/ld: invalid BFD target `rtl'

Given below is my full command line (linking stage):-


gcc -D__UNIX__ -D__I18N__ -D__UNICODE_UNIX__ -D__ORACLE__  -m64  -fPIC 
-o mylibfile.so -I.  file1.o  file2.o  file3.o  file4.o -Wl,-brtl 
-shared -L/oracle/ora10gRel2/lib -lclntsh -lpthread 



By the way my OS is Linux(RH5).


Thanks & Regards,
Dhiraj

More exactly, it is a linker flag, which xlc knows and passes to ld.

Many (most?) non-AIX linkers do not have some kind of this flag, as this
is the default behaviour there. See also ld(1) manpage.

"-Wl,-brtl" informs gcc to pass "-brtl" to ld.

This is the most important information.
You don't need any flag to have "-brtl"-behaviour on Linux.
