Compiling C++ code on Red Hat Linux
 

I am new to doing command line C++ compiling and linking in Linux. I have been a Developer Studio programmer for years in the Windows environment, so I am spoiled. We are porting a group of C++ programs from Solaris 10 to Red Hat version 5 and I am having trouble getting the include and library paths correct in the make file. Getting a "make Error 127" - Command not found when I run the make file. The makefile is shown below.

Any help is greatly appreciated.

ALways paste the whole error, even if you don't know what it all means. It should be telling you what line in your Makefile has a problem.
Here's what I see:

There is an extra space after '=' on several lines. Remove them. Makefiles are not free-form.

There are no instructions in the rule to make convertcips.

I don't see where CCC is defined.

Here is the error. I found the error with CCC, I left off a c in the makefile definition.

Made some progress, objects are being created now. Now need to work on linking objects. Here is the make file again.

did you install the development tools ? ( looks like it ? BUT ???? you might be missing things ?
and did you install from source / or the *-devel.rpm's for ALL prerequisites

most are not installed by default in RHEL
having them on a server is a security risk
( a "bad guy" could then build the spy software on the server)

please USE code tags
manually making make files are a pain sometimes
Autotools are a bit better , but for a small program ?? maybe not

?
where is that coming from ?
it is causing one of the errors

No I did not install from development tools. I have no reference documentation for compiles as this is a new process here and the other developers have not experience with the platform. I am basically shooting in the dark trying to create a basic makefile that works and can be put into a Source Code Control system so the next person after me does not have to feel the pain like I do if changes have and will be made in the future.

Are you trying to build a 32-bit executable or a 64-bit? If you have a 32-bit RHEL, you must be building 32-bit and you can ignore this concern. But if you have 64-bit RHEL, I'm not sure whether the g++ default is 32-bit or 64-bit.

/usr/lib/ is 32-bit even on 64-bit RHEL, so if the g++ default is 64-bit, your choice of usr/lib instead of /usr/lib64 might be an issue (EDIT: after you fix other syntax problems that I didn't initially notice that make your choice of lib vs. lib64 not yet relevant).

I always prefer to have one of -m32 or -m64 in my CPPFLAGS, so there is no ambiguity about what I am trying to build.

so you are moving over to RHEL
is there a reason to use the now, starting to age ,older RHEL5.9
( it is rhel5.9 ? and not 5.1 ?)
and not the current RHEL6.3

The 5 series is supported but it is also starting to show sings of it's old age

With RHEL requiring a support contract your company is paying for the license and the support that comes with it

you can start with the Red hat knowledge base
( loging in to red hat will be required)
https://access.redhat.com/search/quick?
and there is the open to EVERYONE documentation
https://access.redhat.com/knowledge/...erprise_Linux/
the docs for the older 5 are near the bottom
