Hi All,

Here I come again with a newbie question :

I'm trying to build shared libraries on MPE 5.5. I'm using gcc 2.7.2.2
found on
the jazz server ( by the way, the jazz server doesn't hold the 2.8 ? ).

For building my shared library, on MPE, what are the needed flags ?

I thought I needed -f PIC --shared, but at library link time, using

gcc -Wl,-b -o mylib.sl objs.o, the linker fails, claiming no PIC section
must be in my .o !

What is the difference between --shared and -fPIC anyway ?

When compiling my .o with no special flag (not even --shared ) the
library link
occurs with no warning, my binary program ( gcc -o myprog -Wl,-ashared
prog.o -l mylib)  also
links with no problem but running it just leads to a crash :

EXEC FUNCTION FAILED ; subsys 517, info 48
abort : myprog
.....

I see something suspect though using ECHO=1 ( to get the linker traces )

the linkedit linker uses the shared option, which has no real purpose
since this is a final binary.

How to know what is wrong ?

Thanks
