On Win7 with Emacs24 I encounter problems when Emacs programs want to open (pdf) files. The problems remain when I activate or deactivate openwith-mode. I either get a 'wrong-type-argument arrayp nil' message inside Emacs or Acrobat Reader is started but gives an error message 'can't open/find that file'.
I tried to debug it and always ended up in files.el.
It seems that the name of the pdf-file to be opened is constructed by concatenating the absolute filename and the file extension .pdf. However, the filename-string given to AcroRd32 appears to look like this:
AcroRd32 "c:\\absolute\file\name".pdf
This doesn't work on the command line either. I have to change it (manually) to
AcroRd32 "c:\\absolute\file\name.pdf"
or to
AcroRd32 c:\\absolute\file\name.pdf
to make it work.
I don't know if this is considered a bug, or if it is a problem only for me. I tried to change the elisp code to something like
(format "%s" (concat absolute-filename file-extension))
to get rid of those double-quotes, but to no avail. And anyway, I don't feel comfortable to mess around in a basic library like files.el, and its really hard to edebug that library since its invoked permanently.
Maybe somebody encountered the same problem and found a solution?
[I use GNU Emacs 24.0.91.1 (i386-mingw-nt6.1.7601) of 2011-11-22 on MARVIN.]
PS 1 Test Case 1
I get the following error message when I do M-x toggle-debug-on-error and then try to open a pdf file in dired:
Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
file-truename(nil)
find-file-noselect-1(#<buffer test.pdf<4>> "~/.emacs.d/org/projects/sandbox/test.pdf" nil nil "~/.emacs.d/org/projects/sandbox/test.pdf" ((2816 7 . 27468) (16087 . 35227)))
find-file-noselect("c:/Users/tj2/.emacs.d/org/projects/sandbox/test.pdf" nil nil nil)
find-file("c:/Users/tj2/.emacs.d/org/projects/sandbox/test.pdf")
dired-find-file()
call-interactively(dired-find-file nil nil)
and the following message:
Openwith mode enabled
find-file-noselect-1: Wrong type argument: arrayp, nil
Does it matter that my .emacs.d is really a windows symlink (mklink) to a Dropboxfolder?
PS 2 Test Case 2
here is the message I get in the maven-compile buffer, when doing C-c C-s (LilyPond-command-view) in a ,ly buffer:
-*- mode: compilation; default-directory: "~/.emacs.d/org/projects/sandbox/" -*-
Compilation started at Tue Dec 20 09:16:28
AcroRd32 "c:/Users/tj2/.emacs.d/org/projects/sandbox/2test".pdf
Compilation exited abnormally with code 1 at Tue Dec 20 09:16:35
In the message buffer I find
Compilation exited abnormally with code 1
Error during redisplay: (invalid-regexp "Unmatched ( or \\(")
This error doesn't trigger the debugger, although I did M-x toggle-debug-on-error.
Sounds like a bug, to me. Consider reporting it: M-x report-emacs-bug.
Dunno why Michael H. sent you to a Sunrise Commander page with a tip about OpenWith. Perhaps I'm missing something in your question where you indicate that you use one of those packages?
I would suggest reporting an Emacs bug. And if you want to see more about opening Windows apps associated with file types etc. then I'd suggest consulting this page.
This seems to be a problem with openwith.el, so I don't think you'll get much help with an Emacs bug report since openwith.el is not part of Emacs.
I've found a similar error (I'm on Linux) and decided that it would be better to use a "cleaner" alternative that doesn't tweak find-file-noselect (see that page on emacs.sxe for why). The OpenWith wiki page pointed me to a less-popular little bit of glue code,
https://www.emacswiki.org/emacs/download/run-assoc.el (code)
https://www.emacswiki.org/emacs/RunAssoc (docs)
By default this package's run-associated-program is not well-integrated with the usual Emacs workflow, but here is how you can integrate it with helm-find-files (also documented at the above link).
(require 'run-assoc)
(setq associated-program-alist
'(("evince" "\\.pdf$")
("play" "\\.mp3$")))
(defun helm-find-files-maybe-run-assoc (orig-fun &rest args)
(let ((sel (helm-get-selection)))
(if (string-match (mapconcat
(lambda (x) (second x))
associated-program-alist "\\|")
(helm-get-selection))
(run-associated-program sel)
(apply orig-fun args))))
(advice-add 'helm-execute-selection-action
:around #'helm-find-files-maybe-run-assoc)

I'm attempting to make a Lisp package with uiop/package:define-package. I'm using SBCL, and have confirmed that package-local nicknaming ought to be supported:
* *features*
(:QUICKLISP :ASDF3.3 :ASDF3.2 :ASDF3.1 :ASDF3 :ASDF2 :ASDF :OS-UNIX
:NON-BASE-CHARS-EXIST-P :ASDF-UNICODE :X86-64 :GENCGC :64-BIT :ANSI-CL
:COMMON-LISP :ELF :IEEE-FLOATING-POINT :LINUX :LITTLE-ENDIAN
:PACKAGE-LOCAL-NICKNAMES :SB-CORE-COMPRESSION :SB-LDB :SB-PACKAGE-LOCKS
:SB-THREAD :SB-UNICODE :SBCL :UNIX)
* (uiop:featurep :package-local-nicknames)
T
Nevertheless, when I try to define a package that has local nicknames, it doesn't work:
(uiop/package:define-package #:foo
(:use #:cl)
(:local-nicknames (#:b #:binparse)))
debugger invoked on a SIMPLE-ERROR in thread
#<THREAD "main thread" RUNNING {1001878103}>:
unrecognized define-package keyword :LOCAL-NICKNAMES
Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Exit debugger, returning to top level.
(UIOP/PACKAGE:PARSE-DEFINE-PACKAGE-FORM #:FOO ((:USE #:CL) (:LOCAL-NICKNAMES (#:B #:BINPARSE))))
source: (ERROR "unrecognized define-package keyword ~S" KW)
0] 0
(binparse being another package I've made, which worked fine, but which did not happen to use local nicknaming).
What I've found of the uiop/package source seems to indicate that this shouldn't happen? Going by that, it should either work, or have a specific error message indicating the non-supported-ness of local nicknames (if somehow uiop:featurep is inaccurate or changing), but it shouldn't give a generic unknown-keyword error. At this point I'm not sure what I could be getting wrong.
The version of asdf that's included in releases of sbcl is based on asdf version 3.3.1 (November 2017), except bundled into only two (larger) lisp files (one for asdf and one for uiop) rather than breaking them up by purpose as is done in official releases of asdf. asdf added #+sbcl support for package-local nicknames in 3.3.3.2 (August 2019), and switched to the more general #+package-local-nicknames in 3.3.4.1 (April 2020) (the latest release version is 3.3.4, though, so that wouldn't be in yet anyway). So it's "just" a delay in pulling from upstream. Following the instructions on upgrading ASDF did the trick – extract the latest release tarball into ~/common-lisp/asdf and run (load (compile-file #P"~/common-lisp/asdf/build/asdf.lisp")) once, and future shells will use the updated version.
I working on a version bump on the cc65 and encountered a problem with the linuxdoc-tools. Since I can't fix the linuxdoc-tools and there is a simple workaround possible I decided to add an if statement to inform the user together with the workaround:
if {! [file exists ${prefix}/bin/perl] } {
ui_error "
«${prefix}/bin/perl» is missing but the linuxdoc-tools depends on it.
Please create an appropriate symbolic link for linuxdoc-tools to work.
"
exit 1
}
Crude but the best I can do since I'm neither the perl5 nor the linuxdoc-tools maintainer and I don't want to spend to much time on a version bump.
However, the MacPorts doesn't understand exit 1 and ui_error won't stop execution on its own.
How do I stop the execution so not to waste the users time on a build which will otherwise fail right at the end.
Use return -code error "error message", or the shorthand for the same thing, error "error message".
Note that you should use ui_error before that to print a human-readable message for the user – while the error message is also being printed, it can sometimes get lost in the output.
Additionally, note that $prefix/bin/perl is a build dependency of linuxdoc-tools. If it is also needed at runtime, you should submit a pull request that adds depends_run path:bin/perl:perl5 to the port rather than attempting to fix this bug in your port.
I'm very new to the C language and have been tasked with modifying GRUB. What a way to learn, right? Anyway, I'm trying to debug my modified GRUB using VMWare and GDB. I've been able to get the debugger working before, but for some reason, every time I load up my VM and connect GDB, during the loading process of GRUB, I get:
.loadsym.gdb:1: Error in sourced command file:
The address where biosdisk.module has been loaded is missing
and I have no idea what to do about it. My first thought was, "Oh, I'll just add-symbol-file <file> and that'll fix it!" but apparently that tells GDB to forget every other symbol it loaded???? So I can't add the symbol-file and set a breakpoint.
My googling only returns one semi-relevant post that doesn't really go all that in-depth on fixing the issue.
This output may also be relevant.
info file biosdisk.module
Symbols from "H:\Workspace\GRUB\Bootloader\Trunk\grub-core\kernel.exec".
Remote serial target in gdb-specific protocol:

Ended up being that my codebase wasn't the same. That is, on my Windows host, I had one copy of my code and on my Ubuntu VM was another.
Using version control solved this issue.
Does it exists functions for Emacs Lisp which can copy files and directories (with support for TRAMP) and does this asynchronously?
My problem is that (copy-file) and (copy-directory) blocks my editor until they finish and if I do it over TRAMP with a remote-server it takes about 5-10 seconds until I can proceed.
I found the answer to this myself, I use
emacs-async like this:
(async-start
`(lambda()
(copy-file ,local ,remote-path t t)
,local)
(lambda(return-path)
(message "Upload '%s' finished" return-path))))
Place your paths in the variables local and remote-path. For directories, just change (copy-file) to (copy-directory).
Also I think you can use emacs-deferred too, however I haven't tried it yet.
I am working on a remote red-hat server and there I'm developing a c application to insert data in to a remote oracle database. So first i installed the OCI instant client rpm on the server and tried to compile a sample program. after certain linkages I could compile it. But then when I am going to run it. It exits giving an error saying
ORA-12162: TNS:net service name is incorrectly specified
The sample code I used is from the blog (refer to this code in case you need to clarify the things.where I’m quoting only few pieces to this post) René Nyffenegger's collection of things on the web
René Nyffenegger on Oracle
(refer to this code in case you need to clarify the things.where I’m quoting only few pieces to this post)
In the code I added some prints to check for the error And it seems like It gets stuck in the OCIServerAttach() function r gives a printed walue of -1
r=OCIServerAttach(srv, err, dbname, strlen(dbname), (ub4) OCI_DEFAULT);
printf("r value %d",r);
if (r != OCI_SUCCESS) {
checkerr(err, r);
goto clean_up;
}
Another point is that in the compilation process it gives a warning saying that a certain libry is not include. but the exicutable file is created. Here is the massage I get in the compilation process.
[laksithe#loancust ~]$ gcc -L$ORACLE_HOME/lib/ -L$ORACLE_HOME/rdbms/lib/ -o oci_test oci_test.o -L/usr/lib/oracle/12.1/client64/lib -lclntsh `cat $ORACLE_HOME/lib/sysliblist`

Going through the web I found that by creating a tnsnames.ora file with the connection details I could solve the problem. But even It didn't work for me. Here is the link for that blog blog
It has been a week since this error and I cold'nt solve it. could someone please help me.
connection string format I used is abc.ghi.com:1521/JKLMN
My recommendation is to bypass tnsnames completely. Oracle has always allowed you to put in the direct connection details, but EZConnect makes that even easier.
When you format your connection string, instead of listing the TNS name, use the actual connection properties in the following format:
servername:port/service name
For Example
MyOracle.MyCompany.Com:1521/SalesReporting
Your connection string might also require direct=true, but I'm honestly not sure.
I like the idea of tnsnames, but it's a double edged sword. When it works, it's great. When it doesn't, you want to throw something. With EZConnect, it always works.
By the way, if you don't know the properties of the three items above, find a machine that connect via tnsnames and:
tnsping <your TNS-named database>
