Hello,

I am migrating solaris (SPARC) application coded in c/c++ to RHEL5 on
x86_64 platform. The solaris application uses transport layer interface (TLI) calls ( i mean STREAMS API's). But the same STREAMS implemention is not there in RHEL. RHEL uses standard BSD socket calls.

I found the open source implementation of Linux STREAMS on net and downloaded the source. I am not able to build it on Linux platform.

My question is:

Can I invest more time in building the linux streams on Linux platform? or Can I rewrite the solaris code with BSD sockets. Customer doesn't want to change the working code as they feel changing code is more risky.

If anybody has built the Linux STREAMS on Linux platform. please share your experience. Do you see any problems using Linux STREAMS on Linux in the long run.

Please share your thoughts and experience on Linux STREAMS - how should i move in. which is right way to go.

Thanks in advance.

I think there is only one Linux Streams. I assume it's the one from www.gcom.com
(http://email.gcom.com/home/linux/lis/).

I have LiS-2.19 installed on 20 zLinux (IBM mainframe) servers. It was a prereq for IBM's
Comm Server product. The tarball for installation was supplied by IBM (it didn't come off
the gcom site).

It works. I guess that's all that matters. The install was typical of a mid '90s Linux package.
Why IBM can't package their stuff as RPM's is anyone's guess. ..but I rant.

I needed to install a few rpm's as pre-reqs, some for LiS and some for Comm Server. I think
kernel-devel, GCC and glibc-devel were the ones that LiS needed (over what we have in our
standard build). And it required manually adding a line, "#include <linux/autoconf.h>", to
/usr/src/kernels/2.6.18*/include/linux/module.h.

Much more involved than "yum install".

On the gcom site
Doesn't really give you a warm fuzzy feeling that it'll always work as you upgrade the OS.
But it might be acceptable as a tactical solution.

Hope this helps.

Hi,

Can you please let me know how did you resolved all this issue while installing the LiS in Red Hat Linux?..

I m not able to install the LiS in my RHEL 5 and getting some compilation errors.

Could someone help me to resolve this Urgently?

Don't reopen old threads...this thread has been closed for THREE YEARS, and don't hijack someone elses thread with your own question. Both are against LQ Rules. Open your own thread for your own question.

Second...this is a volunteer forum...this is NOT an 'urgent' issue for anyone here, and asking for 'urgent' help is fairly rude. If you need 'urgent' help, then I suggest you CALL RED HAT SUPPORT, since you're using RHEL, you should be PAYING FOR IT. They're there for you 24/7.

You don't say where you got the code you're trying to compile, if you followed the instructions, or what you're typing in to get the message(s) below, so it's hard to give even a guess. Provide details and we can try to help...but another question would be, why not just install this from the packages via yum??
