Hi,

We are using (Redhat 32bit ) and (Suse 64bit) machines .

The g++ compiler version we use is "gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-124.7.2)"

The gcc compiler for suse is "gcc version 3.3.3 (SUSE Linux)"

We're using these compilers and we're not sure what versions of RedHat and SuSE they translate to.

How or Where I can find the linux kernel that these gcc versions support and what versions of RedHat and SuSE does that kernel version translate into?

Please clarify and advise

Please read; http://www.digitalhermit.com/linux/K...ild-HOWTO.html see the section on Software requirements. Word of warning, recently changes with the 2.6 kernel series gcc < 3.X are no longer supported; http://lwn.net/Articles/163881/

I cannot speak about SuSE versions, but with Red Hat kernel versions the basic rule of thumb is, the major number (2.6.9 for example) means the kernel is based on the vanilla 2.6.9 kernel from kernel.org. The extra dash number (-11 for example) means this is the 11th revision (backports and other tweaks) of the base kernel.

Thank you that gave me some information


But let me tell the problem in detail

We build the executables with gcc 2.96 for redhat and gcc 3.3.3
for suse and deliver them to customers .

Now my question is.....

What kernel versions can the customer use to make this executable
(built with gcc 2.96) run perfectly ?

The exact question is ...

For each linux version what kernel versions
customer can use for this executable (built with gcc 2.96)to run?

Previously we faced the problem like .... for some combination of
kernel and linux versions this executable doesnt work.

So can u give me some pointer where can i find this information.

Thanks and regards
Sudhakar

Your making this task a lot harder then it needs to be......

All supported version of Red Hat Linux can support binaries built with gcc-2.96, some will require the compat-liggcc packages. The same is true for gcc-3.3.3 built binaries. For Red Hat Enterprise Linux, 2.X is gcc-2.96 based, 3.x is gcc-3.2.3 based and 4.X is gcc-3.4.5 based. A simple reading of the release notes can tell you this;
http://www.redhat.com/docs/manuals/enterprise/

Notice I said all supported versions, Red Hat ended support for all versions of RHL (the freely downloadabe versions) nearly 2 years ago. Which gcc is supported for these still can be found by reading the release notes forn them;

http://www.redhat.com/docs/manuals/linux/

A simple query of /proc/version will provide an intelligent way to know which gcc version was used to build the kernel. A simple query of gcc will also do the same;

Human readabe quires;

cat /proc/version
gcc --version


I cannot say for SuSE, but I believe all of this could be done pretty much the same way.

Hopefully I pointed you in the right direction, the rest is a matter of research.
