I have broken out the MEMORY{} command of my linker script into a separate file memmap.ld in order to share it between projects (bootloader and target firmware).
The file is currently located in the same directory as the main linker script and I include it using the line
INCLUDE memmap.ld
from my main .ld script however this does not work and I get the error
ld.exe: cannot open linker script file memmap.ld: No such file or directory
when building. The section of the ld manual dealing with the INCLUDE filename command reads
Include the linker script filename at this point. The file will be searched for in
the current directory, and in any directory specified with the ‘-L’ option. You
can nest calls to INCLUDE up to 10 levels deep.
You can place INCLUDE directives at the top level, in MEMORY or SECTIONS commands, or in output section descriptions.
What is up with this? Is the current directory taken from the current script, executable, some other external parameter?
Am using the ST build of the GNU Linker distributed with the 64 bit Windows STM32CubeIDE if it makes any difference.
It appears the matching of .ld scripts within the current directory when using INCLUDE only compares with script names introduced via either '-L searchdir' or '-T scriptfile'.
[i.e. the LD program doesn't do a file system search but instead searches the list of scripts provided during invocation (or at least behaves as such) ].
My case in point when using STM32CubeIDE only provides the option to provide a single loader script via the -T option within project system (while Eclipse Embedded CDT which ST bases it's tools on allows multiple files to be passed by -T) required the addition of the folder containing both my scripts using the -L option (from the Libraries subsection of the Linker project properties).
Once the script I was referencing inside LD was being passed through the build system by including the directory location in the command line the 'current directory' did resolve to that of the script doing the inclusion.

I am using Conan package manager on Windows to create a package. The conan command to create the package copies files to a folder within %USERPROFILE%\.conan (or C:\Users\xxxxxxx\.conan). Then from this location it builds a Visual Studio project and ultimately calls doxygen.exe to create a .chm help file in a post-build command. The doxygen command fails with:
error : failed to run html help compiler on index.hhp
Further investigation reveals the hhc.exe command executed by doxygen is failing with:
C:\Users\xxxxxxx\.conan\data\Module\1.0.0\user\channel\build\524dc97e4a3dd1f774ea3897f9e4faf26c5457d2\Documentation>"C:/Program Files (x86)/HTML Help Workshop/hhc.exe" html\index.hhp
HHC5010: Error: Cannot open "C:\Users\xxxxxxx\data\Module\1.0.0\user\channel\build\524dc97e4a3dd1f774ea3897f9e4faf26c5457d2\Documentation\html\Module.chm". Compilation stopped.
Close inspection reveals that in the error message, the ".conan" folder is missing. Sure enough, I confirmed that hhc.exe fails when the index.hpp resides in a folder that has a parent folder that starts with a ".".
Attempts to resolve this:
changing the Doxyfile setting OUTPUT_DIRECTORY to "$(TMP)/DoxygenModule" resolves the error, but creates the .chm file in another location, which I do not prefer.
navigating to the 8DOT3 name of the ".conan" folder, which is "CONAN~1", to run the hhc.exe command, succeeds, but unfortunately I have no way of getting conan to use this 8DOT3 path for creating the package. E.g. C:\Users\xxxxxxx\CONAN~1\...
I can live with the using the %TMP% folder but would prefer generating the .chm in the current folder. Anyone have any ideas?
HTML Help Workshop v1.31 is installed on my machine at C:\Program Files (x86)\HTML Help Workshop, probably from a Visual Studio installation (not sure). I attempted using a version downloaded from Microsoft website (v1.30) as well, which made no difference.
Other info: Conan version 1.18.0, Doxygen version 1.8.14, Windows 10 Version 1809
Unfortunately not a solution, but this is a known limitation in the hhc.exe, see: https://social.msdn.microsoft.com/Forums/en-US/0681145c-223b-498c-b7bf-be83209cbf4e/issue-with-html-workshop-in-a-windows-container?forum=visualstudiogeneral
HTML Help 1.x command line compiler hhc.exe cannot compile CHM file to folder whose full path contains folder name starting with dot. If you have that problem, you probably specified output path with folder starting with dot, e.g. "d:\My files.NET\documentation". You can use dots in folder names but not at the beginning.
Edit 2019-11-15:
I've just pushed a proposed patch to github (pull request 7402, https://github.com/doxygen/doxygen/pull/7402).
This proposed patch changes inside doxygen from the current directory to the short named current directory, but just for the HTML Help compilation.
Edit 2019-11-16:
Code has been integrated in the master version on github.
This is not an answer either. Actually, you found the answer and workaround[s] yourself.
Use OUTPUT_DIRECTORY to specify a directory containing no folder names beginning with periods.
The error you described is a known issue of the MS HTML Help compiler. More general, the HTML Help compiler does not like some folder and file names. Try and stick with these characters _, a..z, A..Z, 0..9. Do not use these signs in particular ., -, # .
Please note that the proprietary CHM file format is about 20 years old (Windows 95, ...). HTML Help is in maintenance mode, which means no new features and bug fixes are expected for either the runtime or the compiler. All mainstream development on HH has stopped.
There is no way to avoid this error if a directory name above begins with a period. Not even if only the necessary files are written by Doxygen and compiling of the index.hhp is done by a third-party tool like FAR HTML using your path that contains .conan. This is because all applications are using the faulty HHA.dll.
The above applies of course to the entire workflow you have described. Maybe you can interrupt it.
Doxygen can be configured not to call the HTMLHelp compiler. Just uncheck the GENERATE_HTMLHELP option (DoxyWizard: Experts > Topics > HTML). You have all files generated by Doxygen in your preferred output directory - but of course without the CHM file. This can be imported later e.g. by HelpNDoc and compiled as a CHM file in another location.
If you can interrupt the workflow and can also make changes to Doxygen's settings, then a preference setting of OUTPUT_DIRECTORY to e.g. C:/CacheMenu/CONAN~1/DOXYGE~1 also works as expected (here used as test case).
No matter what you do, your workaround and copy and paste from another directory outside is a quick solution at this stage. Please note the EDIT in #albert's answer.
my issue seems to be a common one, but none of the found answers could solve it.
I am following the software foundations course on Coq, and so I come to the command:
> From LF Require Export Basics.
Whatever I try, I get always the following answer:
"Cannot find a physical path bound to logical path matching suffix <>
and prefix LF."
I compiled Basics.v from coqIde, and the Basics.vo file is created correctly.
I also compiled it from the coqc command line, as suggested somewhere
My _CoqProject file exists, in the same folder as Basics.v, and states: -Q . LF
the _CoqProject parameter is set to "appended to arguments".
when I load Basics.v I see on the bottom of CoqIde "Reading Options from ..._CoqProject"
I put the lf folder into a folder which is in the LoadPath of coq.
What else could I check?
My system is Windows 10. I run CoqIde 8.9.1
Thank you!
I usually work under a Linux machine, but here something I did using a virtual machine.
I downloaded the windows installer from https://github.com/coq/coq/releases/tag/V8.9.1
I downladed the lf.tgz file from https://softwarefoundations.cis.upenn.edu/lf-current/index.html
I ran the windows installer for Coq. It placed the coq system in C:\coq
I used cygwin tools to expand the file lf.tgz so that I had a directory C:\Users\user\foundations\lf containing Basics.v, _CoqProject etc.
Then I used the search command to find coqide as an installed app. I then proceeded with the following steps:
start coqide
open the file Basics.v
use the option Compile->Compile buffer
I could then observe that the directory C:\Users\user\foundations\lf contained a file named Basics.vo
Then I opened a new buffer, and wrote From LF Require Export Basics. and did not try to execute this line
I saved this buffer in a file in directory C:\Users\user\foundations\lf. Let's assume this file is named toto.v
I closed the toto.v buffer.
I re-opened the toto.v using the option File->Open
I executed the file contents.
This process is the result of trial-and-error. What I know is that Require Export ... only works if there are ...vo files on you disk, but coqide needs to know where to look for these files. For this it maintains a "load path". When opening a file from a given directory, coqide looks in this directory (and ancestors) to find a _CoqProject file, and the latter may contain directives to modify the load path. It is the case here "-Q . LF" indicates that all .vo files in the current directory should be considered, and that their symbolic name should start with the prefix "LF."
The problem is that when you start from an empty buffer, no _CoqProject file gets read and coqide does not where to look for your data. This is why I did the steps 5-6-7: when reading the file toto.v, I provoked the reading of the _CoqProject file.
Takeaway lesson: Make sure the Basics.vo file exists, and then make sure the buffer you are working on was obtained through a reading operation from the same directory. If needed, save, close, and re-open to make sure this is the case.
I have several build dirs for different configurations (using an external build system from the CLI), so the executable name duplicates the desired cwd:
path/to/build1/executable
path/to/build1 (desired cwd)
path/to/build2/executable
path/to/build2 (desired cwd)
Is there a more convenient way to run the executable from the directory containing it, without typing the path twice?
The most likely solution would be with a variable like ${workspace_loc} under "Arguments -> Working directory", but I could not find a suitable variable.
Tested on Eclipse 4.6.3.
If you use managed build you can get away with specifying config_name appended to workspace_loc, i.e. if you project is called "test" this should work (tested on linux)
${workspace_loc:test}/${config_name:test}
My app prints
Current working dir: /home/elaskavaia/workspace/test/Debug
I am trying to configure Netbeans IDE 7.4 for node-webkit development.
It is excellent IDE but I want to run my projects with F6 button. To do this I added NW.EXE as additional browser (executable is located outside project folder).
After this I have a problem with execution arguments. NW.EXE expects a folder path to be specified as an argument, but I cannot leave empty field of Start File in project settings and the Project URL has to start with either http:// or file:// while Node-webkit needs a path like C:/path_to_app
Does any method exist to deal with this feature?
In short, you can work this around by creating a batch program and let it strip the file name down to the path name part, to be fed to nw.exe, as it requires.
Unfortunately, as you said, we don't have full control over the way the main file of the project is passed to the browser, hence some further actions (in addition to the creation of the batch file) are needed.
This is how I got it working after a bit of struggle:
added nw.exe to the system %PATH% variable (optional, just for ease of access)
created nw.bat in the same folder as nw.exe, and filled it with this content:
#echo %1
start nw.exe %~d1%~p1
The first line of this batch file is just to inspect the actual parameter that is getting passed to the batch file.
The second line uses start to invoke nw.exe without having to wait for its return (you may need to specify the full path to nw.exe, if you didn't add it to the system %PATH% variable).
The second line also passes to nw.exe the drive part of the parameter (extracted from %1 by %~d1) concatenating it to the path of the parameter (extracted from %1 by %~p1).
For instance, my last run from within NetBeans gave this output:
D:\node\test\index.html
D:\node\test>start nw.exe D:\node\test\
Then I needed something to tie the NetBeans run button to an arbitrary executable, and luckily I found a perfect fit.
So here is how I went on:
installed the Node.js Projects plugin from Timboudreau Update Center
went to Options > Miscellaneous > Node.js and set the Node.js Binary field to point to my nw.bat file
In my project, I've also taken care to put package.json in the same folder of index.html (being that that's the main file of my package, and that's what will be fed to the batch file).
Now pressing F6 on my NetBeans installation happily runs my node-webkit project without any further ado :-)
I'm trying to compile C shared library from Matlab. My Matlab code uses a lot of the image processing functionality. So, compiling goes fine, but when I call the dll from my application, I get messages like:
"Undefined function or method 'XYZ' for input arguments of type double".
I have verified my arguments are ok -- it's not a type problem. So, I tried adding %#function XYZ to my .m file, but that didn't help anything. Then, I tried using the -a flag in my compile command:
eval(['mcc -v -N -W lib:cshared -d ' clibdir ' -T link:lib -a edge' allFiles]);
but it fails to compile with:
Depfun error: 'Unable to locate edge as a function on the MATLAB path'
I have verified the image processing files are on my computer (I can run everything from matlab with no problem) and my path points to the directory that contains them.
I've also tried copying the toolbox .m files into my working directory, but that quickly balloons into a lot of files. And, for some functions, there is no .m - just a .mex - and i haven't found a way to include a mex file into my .dll.
What am I missing?
Have you tried including the Image Processing Toolbox folder using the -a option? For example:
mcc ... -a C:\Program Files\MATLAB\R2009a\toolbox\images\images
According to the mcc documentation, all files in this folder, as well as all files in any subfolders, are added to the CTF archive, and the folder subtree is preserved in the CTF archive.
If you don't want to include every subfolder, you can load only the files in a folder using a wildcard pattern:
mcc ... -a C:\Program Files\MATLAB\R2009a\toolbox\images\images\*
This may be necessary if there is a subfolder that may have functions or scripts that could shadow ones in the parent folder. For example, there is an edge.m function in the parent folder C:\Program Files\MATLAB\R2009a\toolbox\images\images\, and there is a ja subfolder that contains Japanese language help files (on Windows), one of which is also called edge.m. You wouldn't want this subfolder to be added when compiling, so you could either:
Remove that subfolder temporarily, add the parent folder without the wildcard option (to add the other subfolders you do want), then put that folder back.
Add the parent folder with the wildcard option (to add just the files), then separately add only the subfolders you want (such as #strel and private) with an additional -a command. NOTE: I'm uncertain if adding subfolders separately will maintain the folder subtree of the parent directory in the CTF archive in the same way as option #1 would!
If you don't want to include a large list of files that may not end up being used, you could instead try using the function DEPFUN to first get a list of dependencies for your MATLAB code. Then from this list you can find the specific Image Processing Toolbox functions your code uses and include only those when compiling. Since you specifically asked, this newsgroup thread mentions how to include a .mex file:
mcc ... -a imreconstructmex.mexw32 %# For a 32-bit Windows mex file
NOTE: There is also a MathWorks bug report I came across (which you need a login to see) that mentions a problem compiling applications using some Image Processing Toolbox functions on Windows in R2009b. There is a workaround given at the above link. This bug is fixed as of R2010a.
