Linking s7 interpreter fails with postgresql 13.3 #7

Closed SiliconWizard closed 2 years ago

SiliconWizard commented 2 years ago

make depend make

At the link step, link fails with an undefined reference to "pg_snprintf" (which should be in libpq?)

postgresql 13.3 (and associated library) installed. There was no problem with earlier versions AFAIR.

Link command line shown is:

gcc -Wl,--gc-sections s7.o ../bin/s7_comp.a ../bin/s7_data.a ../bin/s7_draw.a ../bin/s7_con.a ../bin/s7_db.a ../bin/seed7_05.a -lX11 -lXrender -lncurses -lmysqlclient -lsqlite3 -lpq -lfbclient -lm -ldl -o ../bin/s7

I need more information to address this problem. Please provide the file src/version.h and the actual linker error message. Without that I can only guess what is going on.

AFAIK Postgresql defines its own versions of printf() functions. This includes snprintf(). The postgresql include file port.h defines: #define snprintf pg_snprintf

There is only one place within src/sql_post.c where snprintf() is used. You can try to replace the function setDbErrorMsg() in src/sql_post.c with:

static void setDbErrorMsg (const char *funcName, const char *dbFuncName,
    PGconn *connection)

  {
    char *message;
    memSizeType length;

  /* setDbErrorMsg */
    dbError.funcName = funcName;
    dbError.dbFuncName = dbFuncName;
    dbError.errorCode = 0;
    message = PQerrorMessage(connection);
    length = strlen(message);
    if (length >= DB_ERR_MESSAGE_SIZE) {
      length = DB_ERR_MESSAGE_SIZE - 1;
    } /* if */
    memcpy(dbError.message, message, length);
    dbError.message[length] = '\0';
  } /* setDbErrorMsg */

This code does not use snprintf(). Please tell me if that worked (and send also src/version.h).

I tried modifying the setDbErrorMsg() function. It removed a warning but still have a few, for instance with sql_open_post().

There also are those DWARF errors. Not sure what they mean - don't think I've ever run into those before. Could it be that the latest postgresql libraries on my distribution have issues? I'm using Arch Linux here. I usually don't use postgresql so...

SiliconWizard commented 2 years ago

Note: I tried compiling libpq examples (from here: https://www.postgresql.org/docs/9.1/libpq-example.html ) on the same machine, and it worked without a problem. So libpq seems fine on this machine. Must come from something else. Used the following for compiling the examples: gcc -Wall testlibpq.c -o testlibpq -lpq

ThomasMertes commented 2 years ago

You compiled testlibpq.c without the option -I. The compilation of sql_post.c is done with the options -I/usr/include/postgresql -I/usr/include/postgresql/server This means that include files are also searched in these directories. The file sql_post.c includes:

include "server/postgres.h"

include "libpq-fe.h"

include "server/catalog/pg_type.h"

This means that the file /usr/include/libpq-fe.h exists. Maybe gcc finds the other files at a different place (e.g. in /usr/include/postgresql/server). There could be files from an old version of Postgresql and mixing them does not work.

If you change testlibpg.c to also include these 3 files form sql_post.c you might be able to trigger the same problem (as with sql_post.c). In order to compile testlibpq.c you need to use the same include options also: gcc -Wall -I/usr/include/postgresql -I/usr/include/postgresql/server testlibpq.c -o testlibpq -lp

SiliconWizard commented 2 years ago

The original test programs from the above link just include this:

include

which is all that's needed for them... but it is in /usr/include/ indeed. Same header file as with your approach.

If I change this to the 3 includes you mentioned in the same order, I get undefined symbols indeed ('pg_printf' and 'pg_fprintf' here, but for the same reason.)

I don't think I have several versions of libpq installed. I checked the dates of the include files too. What triggers the issue is when including the 'server/postgres.h' file (which is not needed for the examples I tried), which is where (well, from other files included in it) a lot of things get redefined. Frankly, libpq looks a bit like a mess to me.

As it looks, yes, the standard xxxprintf() functions are all redefined when including 'server/postgres.h', but the own versions they map to (like pg_sprintf) don't seem to be exported in libpq anymore, so link fails. Sorry for bothering you here, with your info, now it really looks like a bug either in libpq, or at least the libpq binaries that are installed by Arch Linux. Could be nice if you could confirm you can link this from your side, with postgresql (and libpq) 13.3. And if so, what systems are you using for developing?

ThomasMertes commented 2 years ago

You could try to remove the line #define POSTGRESQL_POSTGRES_H "server/postgres.h" from version.h and compile Seed7 with make afterwards. This should trigger that server/postgres.h is not included. On my computer it seemed that server/postgres.h is not needed now (IMHO is was neeeded in the past). Unfortunately server/catalog/pg_type.h does not exist on my computer, so I cannot try that solution.

In pg_type.h there are definitions for INT2OID, FLOAT8OID, VARCHAROID, etc. These OID definitions are used by sql_post.c. Unfortunately the place, the name and the existence of pg_type.h has changed several times. There is even code in chkccomp.c to construct a file with OID definitions from another file. Later this other file vanished. They are changing their include files very often... The OID definitions never changed (e.g. INT2OID is always 21) so sql_post.c has no issue with OIDs (besides finding an include file that defines them).

ThomasMertes commented 2 years ago

I just commited a change of src/chkccomp.c, that avoids including postgres.h in sql_post.c. The fix of the function setDbErrorMsg in sql_post.c is not necessary (you can revert it). You can do

git pull
cd src
make clean
make depend
make

for a fresh compile

SiliconWizard commented 2 years ago

Thanks. Your change fixes the issue. I can build s7 and s7c successfully and run tests.
