Thread: Solaris ecpg program doesn't work - pulling my hair out!
I have an ecpg program that runs perfectly on Linux (PostgreSQL 7.4.1). I
recompile it on Solaris and when I try to run it the results are total
gibberish. When I connect:
EXEC SQL WHENEVER SQLERROR GOTO sql_error;
EXEC SQL CONNECT TO :dbTarget USER :user USING :pw;
Where dbTarget = mydb@host.my.domain
user = xxxuser
pw = xxxpassword
The GOTO is not taken and sqlca.sqlcode is set to 0 (no error).
Similarly, when I try to fetch records, either using SELECT or with a
DECLARE CURSOR/FETCH, I get no records and sqlcl.sqlcode is zero (no error).
Since I get no record, but no error is detected, the variables are garbage
and the program SEGV's trying to manipulate the variables.
The above problems occur whether I use valid information for host/user/pw,
or put in totally bogus values. Again, the program works perfectly on
Linux.
Psql works, and handles errors properly. Yet here, nothing works but no
error codes are set.
Any ideas what could be going on? Is ecpg broken on Solaris? Since psql
works, it would seem that the build is valid.

If I had to take a guess, there is something wrong with the ecpg program and the error is masked on Linux, but is visible on Solaris. I would break the program down into small parts and test to see where there error starts. --------------------------------------------------------------------------- wespvp@syntegra.com wrote: > I have an ecpg program that runs perfectly on Linux (PostgreSQL 7.4.1).

The ecpg C code output is identical on both Linux and Solaris. The problem exists all the time - the error code is *never* set (at least never that I've seen). Sqlca is always the same regardless of success or failure of the operation. The reason it appeared valid operations didn't work is I was searching for the wrong record, and since there's no error code set... Wes

I verified last night that this problem also occurs with 7.4.2. I did some
more extensive testing on the solution in my previous follow-up email. That
is definitely the problem - configure is setting "-pthread" instead of
"-lpthread" in config.status. After manually correcting this in
config.status, everything works properly.
I don't know enough about configure to know how to fix configure. It is
properly setting -lpthread on linux.
It's also not clear why the symptoms occur since the build does not abort
with an unsatisfied external. It must be picking up the pthread externals
from soemwhere else? The only difference I can se in the ldd's is the order
of the libraries. An ldd of ecpglib shows:

I realize it isn't entirely meaningful without the source code to know
exactly where I put the print statements, but here is my debug output
running the previously enclosed test program. You can see that it is
allocating a new sqlca structure when it shouldn't be.

I just got this in response to a post to pgsql-general on a different
Solaris problem. This sounds like the same problem as I'm seeing. I've
sent him my solution. Hopefully it will solve his symptoms also.

As stated before, this is not true. If you don't compile with
-D_REENTRANT, the /usr/include/errno.h declared errno as
extern int errno;
instead of the thread safe
extern int *___errno();
#define errno *(___errno())
At least it does so here on Solaris 8. That leads to libpq using the
global errno variable, which might or might not be the one where "your"
error is in a multithreaded program. I mailed the correct solution as a
follow up to the other thread earlier today as a patch against 7.4.2.

Just linking against the right libraries does not do it here. Solaris is
not Linux.

Yep. As I said in a previous email, this is fixed in current CVS and
will be fixed in 7.4.3. Here is the template/solaris file you need:
---------------------------------------------------------------------------
if test "$GCC" != yes ; then
CC="$CC -Xa" # relaxed ISO C mode
CFLAGS="-O -v" # -v is like gcc -Wall
fi
# Pick right test-and-set (TAS) code.

i?86-*-solaris*) need_tas=yes; tas_file=solaris_i386.s ;;
esac
# tools/thread/thread_test must be run
# -D_POSIX_PTHREAD_SEMANTICS enables 5-arg getpwuid_r, among other things
if test "$GCC" = yes
then THREAD_CPPFLAGS="-D_POSIX_PTHREAD_SEMANTICS"
THREAD_LIBS="-pthread"
else THREAD_CPPFLAGS="-mt -D_POSIX_PTHREAD_SEMANTICS"
THREAD_LIBS="-lpthread"
fi

I mailed the correct solution as a > follow up to the other thread earlier today as a patch against 7.4.2. The change I made most definitely corrects the problem I was seeing where I was getting no error handling in ecpg problems. I could correct my problem by rebuilding only libecpg*. Sounds like the problem you found is related, but not exactly the same as what I found. Are you referring to the attachment threadsafe-libpq-742-diff.gz? Unfortunately, I'm committed to 7.4.1 right now, so have to make it work properly. threadsafe-libpq-742-diff.gz is rather large, and I don't think I want to fit it into the 7.4.1 source. I can't just download the latest CVS source. What can I change in my build to get it to properly specify -D_REENTRANT? Sorry, I'm not a configure wiz... >> I don't know enough about configure to know how to fix configure. It is >> properly setting -lpthread on linux. > > Just linking against the right libraries does not do it here. Solaris is > not Linux. The problem I found in config.status is definitely a bug. As released, the build specifies '-pthread' on the GCC command line, which is obviously not a valid GCC parameter. -lpthread needs to be specified, not -pthread. Wes
