Re: Bug #490: Can't compile PostgreSQL 7.1.3 with Solaris 2.6

Holger Mittewald (hrmitter(at)lsd(dot)franken(dot)de) reports a bug with a severity of 1
The lower the number the more severe it is.

Short Description
Can't compile PostgreSQL 7.1.3 with Solaris 2.6

Long Description
Trying to compile postgresql under solaris 2.6 configure stops claiming about an unknown symbol "optreset". I wasn't able to fix the problem.

Sample Code
The last lines of config.log:

[..]
configure:7459: checking for optreset
configure:7471: gcc -o conftest conftest.c -lposix4 -lz -lresolv -lgen -lns
l -lsocket -ldl -lm -lreadline -ltermcap 1>&5

; return 0; }
configure:7497: checking test program

You misread it: the log shows that it's the test after the optreset one
that is failing. That test is just trying to compile and run a trivial
test program. The only reason I can think of for it to fail is if you
have a problem with the libraries that it's linking.

Without seeing the error message it's impossible to guess more than
that...

Not a big surprise: ld doesn't pay attention to LD_LIBRARY_PATH (on
most platforms), but the dynamic loader does.

Hmm. It sounds like we formerly set rpath in the executables on your
platform, and don't anymore. Could you compare the makefiles between
7.0 and 7.1 and see what's changed?
