Undefined reference errors in tls.c during compilation

[tdebaets]

When I try to compile branch 3.0.x on CentOS 5, the compilation fails with these linker errors:

/root/freeradius-server-3.0.x/src/main/tls.c:3295: undefined reference to `tls_error_io_log'

I have no clue why the linker is unable to find the tls_error_log and tls_error_io_log functions, as these are just defined in the same tls.c file. This was probably introduced by commit 8d8234b. Could someone have a look? Thanks!

You probably need to re-run "configure".

[tdebaets]

Unfortunately that didn't help. I get the same errors after a new run of ./configure. Any other ideas?

[alandekok]

Hmm.. CentOS 5 is at least 6 years old, and the base distribution is 10 years old. This kind of bug isn't a high priority.

It's better to use a recent distribution than for us to track down why valid C code doesn't compile.

[tdebaets]

Ok, but the latest 3.0.11 release still compiles and works fine on CentOS 5. I can understand that I can't use 3.1, but shouldn't 3.0 continue to work for the sake of backwards compatibility?

[arr2036]

You have done

rm -rf build
make

right?

[tdebaets]

I have just tried it and it doesn't make any difference. make clean doesn't help either.

[alandekok]

We don't have CentOS 5 here, and aren't inclined to install it just to fix a bug. CentOS is 10 years old, and the base RedHat OS isn't even supported by RedHat any more.

The code seems to be correct, and builds for all Linux / BSD distributions we have access to. So our inclination is to say it's a CentOS 5 bug, and to ignore it.

The larger question is why are you running such an old distribution? It costs nothing to install a recent version of CentOS, which will work.

My FreeBSD 9.3-PRERELEASE (mid 2014) build is failed too. Actually, this seems to be a failure for radeapclient rather than tls.o itself:

v.3.1.x is building OK on the same server, this is v3.0.x issue.

[mcnewton]

Just successfully built a clean v3.0.x HEAD on fresh install of FreeBSD 9.3-RELEASE. No problems at all, including radeapclient.

[edit: refreshed page and see @alandekok just pushed a fix, so that probably explains it... :) ]

[lytboris]

Yeah, I know, I have another RELENG_10 machine with no issues. Will dig it tomorrow properly and update this thread with findings.

[lytboris]

It is arr2036's 8d8234b commit that breaks build. Previous 296eeeb is OK.

[lytboris]

Here you go
#1586

Compilation on CentOS 5 is now again fine as well, thanks!
