Hello @Miguel angel Tortosa pelegrina,
The Micro Focus recommended method for building COBOL subroutines into a library file on Unix/Linux platforms, so that they can be loaded and accessed at runtime, is to use callable shared objects.
In this approach, the COBOL subprograms are linked together into a .so file. The .so file is a shared object, similar to a ".DLL" on Windows. The COBOL runtime system can dynamically load objects of this type at runtime to bring extra modules into a running executable.
A callable shared object can be created with a "cob" command similar to:
cob -z -g -o regards.so -e "" helloworld.cbl goodbyeworld.cbl
The -z tells "cob" to create a callable shared object. The -o option names the resulting callable shared object "regards.so", with a .so extension (on HP/UX, callable shared objects instead carry a ".sl" extension).
Then, the main COBOL program can be compiled (and linked) with a special INITCALL compiler directive to cause the regards.so to be automatically loaded, so that the required subroutines will be available (avoiding a 173 error) when they are called.
cob -C "initcall=regards.so" "-v -xU -o regards main.cbl
For additional background information about creating shared objects on Unix/Linux platforms, please see the following Micro Focus Community article:
Please let me know if you have any questions about the information above.

Error 173 is not found .exe or .dll. I see your
"int-cob-d-01u:/cralm/simep/prue/apps/helloworldv3>cat goodbyeworld.cbl"
probably the dll/exe will be goodbyeworld.exe and you are CALLing "HELLO-WORLD". I believe this is the reason for error 173.

This can't work!
you must use this commands:
CALL "HELLO-WORLD".
CALL "GOODBYE-WORLD".
or
CALL "HELLO-WORLD".
PERFORM STR-GOODBYE-WORLD.
STR-GOODBYE-WORLD SECTION.
CALL "GOODBYE-WORLD".
When use "CALL" its better to use "CANCEL" to remove the program from memory!

Your statement is only true if the configuration default_cancel_mode is changed and "GOODBYE-WORLD" is a DLL, so, int or gnt (not .obj or .o).
Otherwise, GOODBYE-WORLD is logically CANCEL'ed.
If deterministic storage is a requirement, then consider avoiding CANCEL and look at "is initial" phrase on the program-id of GOODBYE-WORLD program.
Lastly, the use of CANCEL is problematic in threaded or hosted threaded environment, so take care with its use.

In order to link an object from a static library into an executable, when only a dynamic call is made in COBOL, you can use the -I option on the cob32 line and specify the symbol name. This will force it to link the object containing that symbol into your executable. Try something like:
cob32 -v -xU -o regards main.o -L . -lregards -I GOODBYE-WORLD

Hi Chris,
Correct. This is a possible solution. In our case, the static library has about 107 objects/routines, fulfilling, in addition, that the routine that is implemented in each object coincides with the filename without extension (.o). The solution found is to do it as follows :
1 # Set COBMODE to 64 for 64bit. Defaults to 32bit.
2 MODE=${COBMODE:-32}

4 cob$MODE -v -xU -o regards main.o $(ar t libregards.a | sed 's/\\.o//g' | sed 's/^/-I /g' | xargs echo) libregards.a

You can do this with the "litlink" directive (I also use another directive "nocase" to make it case-insensitive)
For example:
# ./bld.sh
helloworld.cbl:
goodbyeworld.cbl:
helloworld.cbl:
goodbyeworld.cbl:
# ./regards
Entrada al programa principal...
Hello world!
Goodbye world!
# cat bld.sh
cob -c helloworld.cbl goodbyeworld.cbl
cob -Z -o libregards.so helloworld.cbl goodbyeworld.cbl
cob -C litlink -C nocase -x -L. -lregards -o regards main.cbl

I am not an expert in this area but after some experimentation I find that passing the --whole-archive option to the system linker for that library appears to do what you want.
