Re: build of 7.2.1 on SCO Openserver and Unixware 7.1.1 - Mailing list pgsql-hackers

Bruce,

The reason to move the socket library is that during configuration script
execution, the binary created core dumps if not in the order I gave. You can
check in the port list, some people have been complaining that they could
not even go any further than the configure step and that is the reason.
Here is the message you get otherwise:

checking test program... failed
configure: error:
*** Could not execute a simple test program.  This may be a problem
*** related to locating shared libraries.  Check the file 'config.log'
*** for the exact reason.

In config.log the last lines are:

configure:7516: checking test program
configure:7525: gcc -o conftest -O2


conftest.c -lz -lPW -lgen -lld -lnsl -lsocket -ldl -lm -lreadline -ltermcap
1>&5
configure: failed program was:
#line 7521 "configure"
#include "confdefs.h"
int main() { return 0; }



pow is in the static library libm and SCO Openserver linker does not accept
to link it in a so file. The modification I provide works whithout changing
the way the code works. If there is another way to get libm linked in so
Here is the message I get:

The TCL stuff is because Caldera distribution of TCL is compiled with their
compiler. If you happen to use another compiler on your platform (gcc) it
doesn't work anymore. Caldera compiler has -belf -Kpic options which are
fully incompatible with gcc. That's why I though best to leave the TCL
packages been compiled with the compiler used for postgresql.

Note that I have the same issue for perl modules, but I haven't found a
proper way to correct the make files automatically generated. I understand
that we would want the same compilation options but if you install TCL or
PERL from packages you may not have the same compiler.

Appart these points the regression tests work fine for these platforms. They
are still a few warnings during the compilation process, when I get some
time, I'll try to correct them.
