Programming

hi,
I am trying to build a shared libary to overwrite some standard c functions (malloc etc), now i get the following error:

my system is AIX 5.2

Code:

gcc -fPIC -g -c -Wall mycfile.c

so far so good .o file created--> mycfile.o
now building the .a or .so libary (.a or .so ?? i am not sure which file type ist has to be)

Code:

gcc -shared -WI,-soname,libmystuff.so.1 -o libmystuff.so.1.0.1 mycfile.o -lc -ldl
ld: 0706-005 Cannot find or open file: libmystuff.so.1
        ld:open(): A file or directory in the path name does not exist.
collect2: ld returned 255 exit status

Why is he trying to open libmystuff.so.1 ?? he should create it!

what am i doing wrong?

Can you try this:
Specify the path where you can find the library libmystuff.so.1 with -L during the linking.

Hope it helps...

ldd helps with finding out executable dependencies. Also the command nm helps with linkage problems.
On solaris x86 i have created a shared library in the following manner.
gcc -o libname.so -G prog1.c prog2.c...
then to use the dynamic lib i do the following:
gcc -o progtest progtest.c -L libpath -lname.so and -R for runtime linker library search.
