Compilation of skype_dsp_hijacker on AMD64
by Danyel Ceccaldi, danyel dot ceccaldi at gmx dot de
I want to submit informations back to you, as I tried to compile the
library on opensuse10, on an AMD64 / x86_64 platform.
I encountered the following problem:
$ make
gcc -O2 -Wall -ldl -shared -fpic skype_dsp_hijacker.c -o libskype_dsp_hijacker.so
$ file libskype_dsp_hijacker.so
libskype_dsp_hijacker.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped
$ ./skype_dsp_hijacker skype
ERROR: ld.so: object './libskype_dsp_hijacker.so' from LD_PRELOAD cannot be preloaded: ignored.
Reason:
on this environment, the default architecture to build is 64-Bit, but
skype is 32-bit.
Simply adding CFLAGS=-m32 will not help, as the build environment is not
prepared.
Solution:
assure the following rpm's are installed:
glibc-devel-32bit
glibc-locale-32bit
glibc-32bit
# cd /lib
# ln -s /lib/libdl.so.2 libdl.so
# ln -s /lib/libc.so.6 libc.so
# rpm -i suse/x86_64/glibc-devel-32bit-2.3.5-40.x86_64.rpm
$ gcc -m32 -ldl -shared -fpic skype_dsp_hijacker.c -o libskype_dsp_hijacker.so
$ file libskype_dsp_hijacker.so
libskype_dsp_hijacker.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
(some hints indicated using also -L/lib, but it seems not necessary on opensuse10 or not necessary at all)
As skype binary is as of january 2006 m32 anyway, it should not harm to add the -m32 as a general option.
