The main motivation for this is wanting a successful MinGW build,
which is currently failing with:
guile-guile.o: In function `inner_main':
/home/neil/SW/Guile/ovnight/libguile/guile.c:55: undefined reference to `__imp__gdb_result'
/home/neil/SW/Guile/ovnight/libguile/guile.c:55: undefined reference to `__imp__gdb_output'
/home/neil/SW/Guile/ovnight/libguile/guile.c:55: undefined reference to `__imp__gdb_output_length'
The detailed problem here is to do with how those variables are
declared as exported from the libguile DLL and imported by the guile.c
main program. But in fact we don't need to solve that problem because
the GDB interface is an idea that never actually happened. So here we
just remove the offending variable references from guile.c.
For the record, Guile contains two kinds of GDB support, one of which
is real (and works, last time I tried it), and the other mythical.
The first kind is that libguile includes the utility functions
gdb_print, gdb_eval, etc., and the variable gdb_output. These have no
purpose except for developers to use from GDB when debugging
something. For example, if you have a SCM x and want to know what it
is, you can do:
(gdb) call gdb_print(x)
(gdb) p gdb_output
The second kind is that those utility functions are somehow declared
to GDB, and then GDB itself uses/calls them in some useful way. This
was an interesting idea, but (AFAICT) never actually happened.
I think it's worth leaving gdb_interface.h in the repository and the
distribution, in case this idea is properly resurrected in the future.
* libguile/guile.c (top level): Remove GDB_INTERFACE declaration.
(inner_main): Remove GDB_INTERFACE_INIT call.
* libguile/Makefile.am (guile_LDFLAGS): Remove `@DLPREOPEN@' since it
has no effect.
* libguile/guile.c (main): Don't invoke `LTDL_SET_PRELOADED_SYMBOLS ()'
since it had no effect given how we invoke `libtool'. It also fixes
compatibility issues when using libltdl 1.5 with a Libtool 2.2
package.
"-I$(top_srcdir)/libguile-ltdl".
(libguile_la_LIBADD): Use @LIBLTDL@ instead of
"../libguile-ltdl/libguile-ltdl.a".
* guile.c, dynl.c: Switched to using libltdl directly. Replaced
all references to scm_lt_* with just lt_*. Include <ltdl.h>
instead of <libguile-ltdl.h>.
* NEWS: Corrected remarks about SCM_API.
* configure.in: Defining USE_DLL_IMPORT definition to indicate
usage of DLL import macros in `libguile/__scm.h'.
(LIBOBJS): Removed `fileblocks.o' from the list of object files.
Somehow Jim Blandy's patch from 1997 did not survive.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* configure.in (EXTRA_DEFS): Follow-up patch. Using SCM_IMPORT
instead of __SCM_IMPORT__.
* readline.c (scm_readline_init_ports): Disable input/output
stream redirection for Win32. The readline package for Win32
does not support this. The guile-readline library works fine
for command line editing.
* readline.h (SCM_RL_API): Renamed __FOO__ macros into FOO.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
here (was at guile_LDADD) which describes the dependency
correctly and allows a clean build on Win32.
* __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
into FOO.
* __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
import macros for external libraries (libcrypt, libqthreads,
libreadline and libregex).
* coop-defs.h: Include <winsock2.h> for `struct timeval'.
* posix.c (flock): Added support for flock() in M$-Windows.
* guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
of __SCM_IMPORT__.
* fports.c (getflags): Differentiate reading and writing pipes
descriptors.
* filesys.c (S_IS*): Redefine all of the S_IS*() macros for
M$-Windows.
* coop.c (coop_condition_variable_timed_wait_mutex): Use
conditionalized error code if `ETIMEDOUT' is not available.
(scm_thread_usleep): Remove bogus declaration of `struct timeval
timeout'.
* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
belongs. That is because NO_PREPRO_MAGIC gets undefined after
each inclusion of `num2integral.i.c'.
(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* md/Makefile.am (EXTRA_DIST): Added `i386.asm'.
* md/i386.asm: New file. Contains the Intel syntax version for
nasm/tasm/masm of the file `i386.s'.
* qt.h.in: Definition of QT_API, QT_IMPORT and QT_EXPORT.
Prefixed each symbols which is meant to go into a DLL.
* Makefile.am (libqthreads_la_LDFLAGS): Put `-no-undefined'
into LDFLAGS to support linkers which do not allow unresolved
symbols inside shared libraries.
(EXTRA_DIST): Add `libqthreads.def', which is an export file
definition for M$-Windows. It defines exported symbols. This is
necessary because the M$VC linker does not know how to export
assembler symbols into a DLL.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* srfi-13.h, srfi-14.h, srfi-4.h: Follow-up patch. Renamed
__FOO__ macros into FOO.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* tests/ports.test: Run (close-port) before (delete-file) if
necessary/advisory.
and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
so guile.c can be very small (and eventuallly auto-generated. (I
mean, generated mechanically, not self-generated. Hmm.))
* guile.c, script.c, script.h: New source files.
* init.c (scm_boot_guile_1): Call scm_init_script.
* libguile.h: #include "script.h".
* Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
targets, for new executable.
(libguile_la_SOURCES): Mention script.c.
(modinclude_HEADERS): Add script.h.
* configure.in: Always check for -lm, -lsocket, -lnsl, whether or
not dynamic linking is enabled. This is because we're generating
executables now. Move CY_AC_WITH_THREADS call after those, so the
values of cy_cv_threads_libs captures the libs chosen above.
* Makefile.in, configure, aclocal.m4: Regenerated.
