The generated library does indeed contain all systems that your library
contains on. The undefined references are init functions, which need to
be called via ecl_init_module after cl_boot to initialize the compiled
libraries (see
https://common-lisp.net/project/ecl/static/manual/System-building.html#Build-it-as-shared-library-and-use-in-C
for more details).
Since you didn't specify an explicit init name yourself, init functions
are automatically generated for each system contained in the final
library. When compiling a monolithic library, it is preferable to
specify an explicit init name yourself, for example as
(asdf:make-build :embedded-console :type :static-library :move-here
#P"/my/output/dir" :monolithic t :init-name "init_lib_embedded_console")
and then invoke it using
extern void init_lib_embedded_console(cl_object);
/* ... */
cl_boot(argc, argv);
ecl_init_module(NULL, init_lib_embedded_console);

Hello. I am trying to make a library that makes use of 'STR' package and
link it into my C program.
I presumed that using :monolithic t flag would result in the static
library that contained all systems my library depends on. However it
seems that is not the case.
Here is my .asd file:
(defsystem "embedded-console"
:description "embedded console - ECL functions for smart snake game"
:author "Ivan Truskov <tru...@gmail.com <mailto:tru...@gmail.com>>"
:components ((:file "embedded-console"))
:depends-on ("str"))
I am compiling the library with command:
ecl -norc -eval '(require :ecl-quicklisp)'
-eval '(push \"/my/src/dir/\" asdf:*central-registry*)'
-eval '(asdf:make-build :embedded-console :type
:static-library :move-here \#P\"/my/output/dir}\" :monolithic t )'
-eval '(quit)'
However, when i try to link with resulting library, this is what i get:
... undefined reference to `init_lib_CL_PPCRE'
... undefined reference to `init_lib_BASE'
... undefined reference to `init_lib_CL_UNICODE'
... undefined reference to `init_lib_CL_PPCRE_UNICODE'
... undefined reference to `init_lib_CL_CHANGE_CASE'
... undefined reference to `init_lib_STR'
... undefined reference to `init_lib_EMBEDDED_CONSOLE'
And indeed, when i run nm over the built file
embedded-console--all-systems.a, this is output:

What am i doing wrong? What should i change to get static library
containing all systems i am intending to use (and maybe only them, if
possible)?
