* Add windows stubs for dlopen, dlclose, dlsym, dlerrorMike Gran2021-03-111-0/+8
| | | | | | | | | | * libguile/dynl.c [__MING32__] (dlopen, dlsym, dlclose, dlerror): use windows stubs * libguile/posix-w32.c (dlopen_w32, dlsym_w32, dlclose_w32, dlerror_w32): new procedures (dlerror_str): new module-level variable (DLERROR_LEN): new define * libguile/posix-w32.h: declare dlopen_w32, dlsym_w32, dlclose_w32, dlerror_w32. Declare RTLD_NOW, RTLD_LAZY, RTLD_GLOBAL, RTLD_LOCAL
* Replace libltdl with raw dlopen, dlsymAndy Wingo2021-02-031-312/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * NEWS: Update. * am/bootstrap.am (SOURCES): * module/Makefile.am (SOURCES): Add system/foreign-library.scm. * configure.ac: Replace ltdl check with -ldl check. * libguile/dynl.c: Rewrite to just expose core dlopen / dlsym / etc to a helper Scheme module. (scm_dynamic_link, scm_dynamic_pointer, scm_dynamic_function) (scm_dynamic_object_p, scm_dynamic_call): Rewrite in terms of (system foreign-library). * libguile/extensions.c (load_extension): Avoid scm_dynamic_call. * module/system/foreign-library.scm: New file. * module/oop/goops.scm (<dynamic-object>): Hackily export <foreign-library> instead of a class here. * doc/ref/api-foreign.texi (Foreign Function Interface): Rewrite to only document the new interfaces. Eventually we will deprecate dynamic-link and friends. * doc/ref/guile.texi (API Reference): Move Foreign Objects after Foreign Function Interface. Seems there should be some closer relationship but this will do for now. * doc/ref/tour.texi (Putting Extensions into Modules): * doc/ref/libguile-parallel.texi (Parallel Installations): Update for rename of Modules and Extensions to Foreign Extensions. * libguile/deprecated.h: * libguile/deprecated.c (scm_dynamic_unlink): Deprecate. * libguile/guile.c: Remove ltdl include. * test-suite/tests/foreign.test: Update tests to use new API, and update error expectations.
* Interpret dynamic library name as literal file name first.Isaac Jurado2020-03-221-4/+3
| | | | | | | | | | | Fixes <https://bugs.gnu.org/21076>. * libguile/dynl.c (sysdep_dyn_link): Try plain lt_dlopen first, to interpret fname as a literal path. * doc/ref/api-foreign.texi: Update explanation to describe the new behavior. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
* Update license notices in all C filesAndy Wingo2018-06-201-19/+19
| | | | | Update to newest recommended license notices from the FSF. Everything stays LGPLv3+ except guile-readline which is GPLv3+.
* Remove (C) from copyright statementsAndy Wingo2018-06-201-1/+1
| | | | | | As the FSF advises, 'There is no legal significance to using the three-character sequence “(C)”, but it does no harm.' It does take up space though! For that reason, we remove it here from our C files.
* Make .c copyright headers uniformAndy Wingo2018-06-201-0/+1
|
* Rationalize include order in C filesAndy Wingo2018-06-201-30/+14
| | | | | Include config.h first, then system includes, then libguile includes, in alphabetical order, then the include for the file in question.
* Make libguile header inclusion consistent within libguile c filesAndy Wingo2018-06-201-14/+14
| | | | | Change from '#include "libguile/foo.h"' and '#include <libguile/foo.h>' to '#include "foo.h"'.
* Remove Emacs local variables comments in Guile sourceAndy Wingo2018-06-201-6/+0

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * libguile/foreign.c: * libguile/foreign.h: Rework interface to be more pointer-centric. Details are: (SCM_FOREIGN_TYPE_STRUCT, SCM_FOREIGN_TYPE_POINTER): Removed; now the pointer in a foreign is first-class. If it points to a native type like uint32, then it still has a tag; but if it points to something else, like a struct or a pointer or something, then its type is VOID (i.e., void*). (SCM_FOREIGN_POINTER): Rename from SCM_FOREIGN_OBJECT. (SCM_FOREIGN_VALUE_REF, SCM_FOREIGN_VALUE_SET): Rename from SCM_FOREIGN_OBJECT_REF and SCM_FOREIGN_OBJECT_SET, to indicate that they only work with value types. (SCM_FOREIGN_HAS_FINALIZER): Reserve a bit to indicate if the foreign pointer in question has a finalizer registered. (SCM_FOREIGN_LEN): For void* pointers, optionally store the length in bytes of the associated memory region. (SCM_FOREIGN_VALUE_P): Rename from SCM_FOREIGN_SIMPLE_P. (SCM_VALIDATE_FOREIGN_VALUE): Rename from SCM_VALIDATE_FOREIGN_SIMPLE. (scm_take_foreign_pointer): Rename from scm_c_take_foreign. Remove scm_c_from_foreign. (scm_foreign_type): New accessor. (scm_foreign_ref, scm_foreign_set_x): Take some optional args, used when dereferencing void pointers. * libguile/dynl.h: * libguile/dynl.c (scm_dynamic_pointer): New function, used by scm_dynamic_func. Adapt code to foreign.h changes. * libguile/goops.c (scm_enable_primitive_generic_x) (scm_set_primitive_generic_x): Use the SCM_SET_SUBR_GENERIC macro. * libguile/gsubr.c (create_gsubr): Adapt to API change. * libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_GENERIC): Store the pointer directly, not indirected. * libguile/snarf.h (SCM_DEFINE, SCM_IMMUTABLE_FOREIGN): Store subr pointers directly. Adapt to SCM_FOREIGN_TYPE_VOID change. * libguile/vm-i-system.c (subr-call): Access the void* directly.
* dynamic-func returns foreign objects, not bignumsAndy Wingo2010-01-041-8/+8
| | | | | | | | * libguile/dynl.c (scm_dynamic_func, scm_dynamic_call) (scm_dynamic_args_call): Change the representation of dynamic functions to be foreign objects. Shouldn't affect any users, as people should be treating the return value of dynamic-func as an opaque object.
* add $libir to the ltdl path, not $pkglibdir; add extensionsdirAndy Wingo2009-10-131-4/+7
| | | | | | | | | | | | | | | | * libguile/Makefile.am (libpath.h): Fix SCM_LIB_DIR to point to the libdir, not pkglibdir. Add SCM_EXTENSIONS_DIR, for a dir to put in the dynamic-link search path that's not managed by ldconfig or the like; and put this dir in the "extensionsdir" key of %guile-build-info. * libguile/dynl.c (sysdep_dynl_init): Rename the installed-libdir environment var to GUILE_SYSTEM_EXTENSIONS_PATH (from GUILE_SYSTEM_LTDL_PATH). Also add SCM_EXTENSIONS_DIR to the ltdl search path in the default case. * meta/uninstalled-env.in: Adapt override to match. * meta/guile-2.0.pc.in: Add extensionsdir, so you can pkg-config --variable=extensionsdir guile-2.0.
* add the libdir to the ltdl lib search pathAndy Wingo2009-09-161-0/+15
| | | | | | | | | | | | | | | | | | * libguile/Makefile.am (libpath.h): Fix pkgdatadir, pkglibdir, and pkgincludedir entries. Add a new define, SCM_LIB_DIR. * libguile/dynl.c (sysdep_dynl_init): Add the libdir to the libltdl search path. Should fix http://thread.gmane.org/gmane.lisp.guile.bugs/4289/focus=4296 -- that is, it should allow guile to be invoked from whereever it is installed, without munging LTDL_LIBRARY_PATH or the like variables. There is a trick though -- during the build, we don't want to be looking in the $libdir for loadable modules. So as with GUILE_SYSTEM_PATH, we have GUILE_SYSTEM_LTDL_PATH. * meta/uninstalled-env.in: Set GUILE_SYSTEM_LTDL_PATH to "" when building.
