This note includes:
Installing this patch
- Log in as root (or with administrator privileges on Windows).
- On Debian 3.1 hosts, set up your environment by typing:
source /etc/profile
- Download the PSP_kernel-libc-patch51_br650_be650SP1-51_kernel-libc-x86.tar archive to your host environment.
- Verify that the patch's checksum matches the one given on our website.
- On Windows hosts, run cmd.exe.
- Use the applypatch utility to install the patch:
- On Linux, if you use sudo (as would be the case on Ubuntu),
you must specify the -E option to preserve the environment.
In this case, the PATH environment variable is set
to a safe one for security reasons, so you need to specify the full path to
the utility:
sudo -E $QNX_HOST/usr/bin/applypatch PSP_kernel-libc-patch51_br650_be650SP1-51_kernel-libc-x86.tar - On other hosts, type:
applypatch PSP_kernel-libc-patch51_br650_be650SP1-51_kernel-libc-x86.tar
For more information about applypatch, see its entry in the Utilities Reference.
On QNX Neutrino and Linux hosts, you'll get a warning that ldqnx.so.2 is newer on the disk than in the patch. This happens because ldqnx.so.2 is a symbolic link to libc.so.3, which is also updated in this patch. It doesn't matter how you respond to the question about replacing ldqnx.so.2. On Windows (which doesn't support symbolic links), ldqnx.so.2 is a copy of libc.so.3, so the warning doesn't appear.
- On Linux, if you use sudo (as would be the case on Ubuntu),
you must specify the -E option to preserve the environment.
In this case, the PATH environment variable is set
to a safe one for security reasons, so you need to specify the full path to
