I have an Oracle 10g (release 1) database running on an IBM p520
running AIX 5.3, with the appropriate MicroFocus COBOL compiler
installed.

I am trying to compile the first of the sample programs in the
..../precomp/demo/procob2 directory.

The command I use (and the output I get) is as follows :-

# make -f demo_procob.mk sample1
/bin/make -f
/apps/oracle/10g/precomp/demo/procob2/demo_procob.mk build
COBS=sample1.cob EXE=sample1
cob -C IBMCOMP -C NESTCALL -x -t -o sample1 sample1.cob
-L/apps/oracle/10g/lib/ /apps/oracle/10g/precomp/lib/cobsqlintf.o
-lclntsh -lld -lm `cat /apps/oracle/10g/lib/sysliblist` -lm -lc_r
-lpthreads
Could not load program /usr/lpp/cobol/bin/rts32_t:
Dependent module libcobrts_t.2.so could not be loaded.
Could not load module libcobrts_t.2.so.
System error: No such file or directory
cob32: error(s) in compilation: sample1.cob
make: 1254-004 The error code from the last command is 255.


Stop.
make: 1254-004 The error code from the last command is 2.


When I check for the files mentioned (with the ls command) :-

# ls -l /usr/lpp/cobol/lib/libcobrts_t.2.so
-r-xr-xr-x 1 root system 1141066 Mar 20 2003
/usr/lpp/cobol/lib/libcobrts_t.2.so

# ls -l /usr/lpp/cobol/bin/rts32_t
-r-xr-xr-x 1 root system 3870 Mar 20 2003
/usr/lpp/cobol/bin/rts32_t

I suspect that the problem is probably environmental, as I am able to
build the MicroFocus demo programs with no problems. However, The
LD_LIBRARY_PATH variable seems to be correct, and I'd thought this was
where it should be looking for the "so" file, no?


Thanks in advance for any insights anybody might be able to offer. I'm
a newbie in the Pro-COBOL world

There is no LD_LIBRARY_PATH in AIX, I guess that you mean LIBPATH.

To see why libcobrts_t.2.so cannot be loaded, try

ldd /usr/lpp/cobol/bin/rts32_t

and

ldd /usr/lpp/cobol/lib/libcobrts_t.2.s

Yours,
Laurenz Albe

Thanks for the fast response Laurenz!

I think most flavours of unix use the LD_LIBRARY_PATH, but I guess AIX
is a little different, and uses LIBPATH. However, I notice that my
environment has both defined.

I used the ldd command (very useful), as shown in the text below. I'm
able to see the dependencies, but all seems to be well. I did issue
the ldd command for the other libraries mentioned under rts32_t, but
didn't stumble across any missing files. Are there any other
environment variable that are related to finding paths to libraries
under AIX?

The output from my test with ldd is shown below :-

# echo $LIBPATH

Being totally ignorant of Cobol (fortunately) or this compiler in
particular, I don't know how 'cob' tries to load 'rts32_t'.

But I guess it just executes it, right?

There is one more thing that could be the problem:

Does any of the executables in question (cob, rts32_t, whatever else may
be called in the makefile that calls cob) have the SETUID flag set?

I ask because if a SETUID program is executed on AIX by a user OTHER THAN
THE OWNER of the executable, the LIBPATH will be ignored (for security
reasons).

If that is your problem, your options are the following:

- Link rts32_t with a linker path that points to the shared library
(you need to have the source of rts32_t for that).

- Create a symbolic link to /usr/lpp/cobol/lib/libcobrts_t.2.so
in /usr/lib. It is ugly, but should work.

Yours,
Laurenz Albe

Once again, thank you for your input! The Cobol compiler was indeed
installed using the root account, rather than some less-privileged
account. Once installed with such an account, everything starts to
make sense!!

Thanks again!
