Problem Creating Shared Library

Lalit Seth — Fri, 02 Apr 2004 07:24:24 GMT

Hi,

I m using gcc 3.3.3 11.11/32 bit binary created by Merjin on hppa2.0w.

I have created xaa.cpp
#include

void name()
{
cout<<"Name"<}

Then compile it using
g++ -c -g xaa.cpp
which does fine
now when i create shared library of this using
g++ -g -shared -fPIC -o xaa.so xaa.o
results in
/usr/ccs/bin/ld: Invalid loader fixup in text space needed in output file for symbol "std::basic_ostream >& std::endl >(std::basic_ostream >&)" in input file "xaa.o"
collect2: ld returned 1 exit status

How can i resolve this???

Rgds

Try doing the first compile from C++-code to object file with the -shared option. That should help, according to the man-page description of -shared option of g++.

Have you tried without the debugging code? (remove the -g options from both g++ calls)

Tryed this
g++ -c -fPIC -shared xaa.cpp
g++ -fPIC -shared -o xaa.so xaa.o

and got

/usr/ccs/bin/ld: Invalid loader fixup in text space needed in output file for symbol "__gxx_personality_sj0" in input file "../HPUXGCC3.3.3-32/pa20_32/lib/libstdc++.a(ios.o)"

The problem is that libstdc++.a is not compiled as Position Independent Code (-fPIC).

You have 2 options:
* Recompile libstdc++.a as position independent.
* Link with libstdc++.sl shared library.

I have recompiled libstdc++.a as position independent and this problem was disappeared.

Could you try compiling xaa.o with the +z/+Z option which enables it to be linked as a shared library.

You might also try linking with with standrad c library with "-lc" tag if that doesnt work.
