Re: Monolithic build of static library

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);
