Hi!
All of a sudden, I can't link my programs any longer. This affects all
my programs, which I build with a shared Makefile. But I haven't
changed the Makefile...
I get messages like this (indentation by me):
cc build/sicherung.o build/Hsskripte.o build/Sicherung.o
build/SicherungAktionen.o build/Text.o build/Wahl.o build/Zeit.o
build/hssk.o -o build/sicherung
/usr/bin/ld: build/sicherung.o: relocation R_X86_64_32S against
undefined symbol `stg_upd_frame_info' can not be used when making a
PIE object; recompile with -fPIC
/usr/bin/ld: build/Hsskripte.o: relocation R_X86_64_32S against
`.text' can not be used when making a PIE object; recompile with
-fPIC
... more like this ...
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o:
In function `_start':
(.text+0x20): undefined reference to `main'
/usr/bin/ld: final link failed: Invalid operation
collect2: error: ld returned 1 exit status
I've attached the complete build messages.
I've never dealt with position independent code. I've tried that "-
fPIC" switch, but this produces lots of new error messages.
Any idea of what's wrong?
Bye,
V.W.
