Hello,
I want to use a second glibc on Linux; mainly for hacking glibc;
I do want to keep the original glibc with came with my distribution.
(Which is RedHat 9)
so that the kenel and apps will still use it.
I have succeeded in building glibc 2.3.2 ; I had installed it to a
private folder (using ./configure --prefix=/work/myglibc) so it will
not interfere with any system libraries.
Now , I am trying to compile and link a simple HelloWorld program in
"C" against the glibc I
had made. As I understand fromm googling , I should use the new
libc.so and the new dynamic linker (ld.so.)
How should it be done?
I googled for it a littlem,and I made some attempts with various make
files, and they all failed (sometimes the compile succeeded but when
running the
executable I got a core dump).
I don't want to get into details about these attempts because I assume
the way to do
it is probably straightforward for those who have some experience with
it; so
if anybody knows something, please ,let me know.
Regards,
Amir
LD_LIBRARY_PATH may be your friend here, as may LD_PRELOAD. These allow
you to override the default place the system looks for libraries via an
environment var, which can be set per-process.
