tacc not found

[lucevers]

Seems that tacc is not compiled.
Could not found the program after installing pam_tacplus.

Can you attach the output of your make? Not giving a lot of useful information to go by here.

The issue is not announced in the make process, but it is if you attempt to compile the tacc.c manually:

# gcc tacc.c -o tacc
tacc.c:30:26: fatal error: openssl/rand.h: No such file or directory
 #include <openssl/rand.h>
                          ^
compilation terminated.

This issue can be fixed by either installing libssl-dev in Debian or openssl-devel in RHEL base.

Of course the package containing the headers needs to be present to compile. Also, when you compile manually you're not passing in all the flags that a make-based compile would, so of course it's not going to work properly.

Neither of these is really a bug. That's normal usage.

If you look here:

https://github.com/jeroennijhof/pam_tacplus/blob/master/configure.ac#L39
https://github.com/jeroennijhof/pam_tacplus/blob/master/configure.ac#L54

you'll see that TACC only gets defined if a library (called libcrypto.a or libcrypto.so) containing the function RAND_pseudo_bytes is found. And you'll see here:

https://github.com/jeroennijhof/pam_tacplus/blob/master/Makefile.am#L13

that tacc only gets built if TACC was defined above (i.e. a libcrypto.a containing RAND_pseudo_bytes) was found.

If those conditions aren't met, then only the minimal components which can be built are built.

Correct, I should've included the extended piece instead of the short one where I was replicating the make flags.

[pprindeville]

That's not really the point. If you want to (re-)compile tacc, then you do so as:

make tacc

[rx13]

Worth noting, in Debian 8.7* (kernel 4.7.5), you also need to replace -Werror with -Wno-deprecated to compile successfully with all dependencies. tacc is working for me at this time. Thanks. (adjusted per follow-up comment -- need more coffee)

[pprindeville]

I don't think you need to replace -Werror so much as supplement it as -Werror -Wno-error=deprecated. Can you post the errors that you're seeing when you build? And why are you using such an old version of Debian? I don't think anyone expects a current project to build under such an old release. Etch is now 10 years old.

[rx13]

In short, make was running with no issue (reported), but it was never spitting out the tacc client.
So I replicated as many of the flags from make as I could, and realized it was missing libssl.
Once that was fixed, it was failing to compile due to deprecation errors.
That's when I pulled -Werror (in place of the more sensible -Wno-error=deprecated)

So, had I not needed tacc, it likely would have never been noticed.

[pprindeville]

Once that was fixed, it was failing to compile due to deprecation errors.

Without seeing the previously requested errors, I can't tell if that's definitively true or not, but I strongly suspect that the errors have to do with your using a very old version of Debian (and hence a very old version of OpenSSL, probably pre 1.0.0).

[pprindeville]

Can you post your compilation messages from an unmodified cloning?

[pprindeville]

Can't fix it without more information so closing the issue.
