Old c compilers needed for 9i on Red Hat Linux
9i on Red Hat Linux (with the exception apparently 32-bit on RH3) won’t install unless you revert the c compilers back to old versions. Horrible. But fixed (I am told) with oracle 10g.
And its not something you necessarily want to do just for the install – because future patchsets and even some one off bugfixes will need to use the old compilers also.
Also note that on Red Hat, you don’t get a choice with oracle word size – if you have built a 64 bit OS kernel, then you have to use 64 bit oracle, and (obviously) vice versa. That’s different to SPARC Solaris, where you can happily run 32 bit oracle on a 64 bit kernel (if for some strange reason you ever wanted to). However it is possible to run a 32 bit kernel OS on 64 bit hardware. “uname -a” tells you whether the OS kernel is 32 bit or 64 bit – if it reports “i386”, its 32 bit; “i386-64” means its 64 bit.
On RH4, for both 64-bit and 32-bit:
1) Revert back to an old c compiler (as the root userid):
mv /usr/bin/gcc /usr/bin/gcc.orig mv /usr/bin/g++ /usr/bin/g++.orig ln -s /usr/bin/x86_64-redhat-linux-gcc32 /usr/bin/gcc ln -s /usr/bin/x86_64-redhat-linux-g++32 /usr/bin/g++
2) Set environment variable (as the oracle userid before running installer):
export LD_ASSUME_KERNEL=2.4.19
On RH3 64-bit:
1) apply patch 3423540 before running the installer
2) Set environment variable (as the oracle userid before running installer):
export LD_ASSUME_KERNEL=2.4.19
On RH3 32-bit:
1) Revert back to an old c compiler (as the root userid):
mv /usr/bin/gcc /usr/bin/gcc323 mv /usr/bin/g++ /usr/bin/g++323 ln -sf /usr/bin/gcc296 /usr/bin/gcc ln -sf /usr/bin/g++296 /usr/bin/g++
2) apply patch 3006854 before running the installer
3) Set environment variable (as the oracle userid before running installer):
export LD_ASSUME_KERNEL=2.4.19
(Caveat emptor: I’ve only done installs of RH4 64-bit and RH3 32-bit, so the information for the others is from metalink only.)
