I have a problem with invoking gcov, it keeps returning - No such file or directory.
When I call
localhost:R-3.0.1 romantsegelskyi$ gcov src/main/eval.c
eval.c: No such file or directory
However file itself and information needed for gcov exists.
localhost:R-3.0.1 romantsegelskyi$ ls src/main/eval*
src/main/eval.c src/main/eval.d src/main/eval.gcda src/main/eval.gcno src/main/eval.o
I have tried specifying --object-directory but still no luck
localhost:R-3.0.1 romantsegelskyi$ gcov src/main/eval.c --object-directory=./src/main
eval.c: No such file or directory
Strangest thing is that it is only the case on OSX, on Linux everything works fine as intended. Any ideas?
Same behavior !! And more strange : I get the result (the .gcov file), following this mesg !! Perhaps, you have the result too ?
There two aspects in the problem :
gcov manual said that gcov should execute by default in the directory where the object file and the gcov data files are. The first and simplest working solution is : go in the appropriate directory and execute gcov cd src/main; gcov eval.c
why the --object-directory=... arg seems not working ? Because the expected value is a directory name and in the example given, it is a file name. So you should write --object-directory=src/main (this work too)
or --object-file=src/main/eval.c (according to the doc. I haven't tried this !)

I am using the moderncv class to create a CV in Rmarkdown. In order to make the cv reproducible out of the box I have included the .cls and .sty files in the root directory. However, in an effort to keep the root directory uncluttered I would prefer to keep all the moderncv related files in a subdirectory (assets/tex/). I am able to access the .cls file using a relative path in the yaml front matter, but I am not able to access the .sty files unless they are in the root directory.
Searching previous questions on stackoverflow I learned the following: (1) keeping .cls and .sty files in nested directories is not recommended. I understand this and would like to do it anyway so that other people can fork my project and be able to knit the cv without having to deal with finding their texmk folder. (2) the solution to my problem seems to involve setting the TEXINPUTS using a Makefile (see this thread and another thread)
I am not very good with Makefiles, but I have managed to get one working that will knit my .Rmd file to pdf without problems, so long as the .sty files are still in root. This is what it looks like currently:
PDF_FILE=my_cv.pdf
all : $(PDF_FILE)
echo All files are now up to date
clean :
rm -f $(PDF_FILE)
%.pdf : %.Rmd
Rscript -e 'rmarkdown::render("$<")'
My understanding is that I can set the TEXINPUTS using:
export TEXINPUTS=".:./assets/tex:"
Where "assets/tex" represents the subdirectory where the .sty files are located. I do not know how to incorporate the above code into my makefile so that the .sty files are recognized in the subdirectories and my .Rmd is knit to PDF. In its current state, I get the following error if I remove the .sty files from root and put then in the aforementioned subdirectory:
! LaTeX Error: Command \fax already defined.
Or name \end... illegal, see p.192 of the manual.
which I assume is occurring because the moderncv class needs---and cannot locate---the relevant .sty files.
You could try to define the environment variable in the make rule:
%.pdf : %.Rmd
export TEXINPUTS=".:./assets/tex:"
Rscript -e 'rmarkdown::render("$<")'
Or you could set the environment variable in a set-up chunk in your Rmd file:
```{r setup, include = FALSE}
Sys.setenv(TEXINPUTS=".:./assets/tex:")
```
Note: Not tested due to lack of minimal example.
I have an algorithm in C++ (main.cpp) and I use CLion to compile and run it. Algorithm would read strings from text file, but there is a mistake:
Could not open data.txt (file exists and placed in one folder with main.cpp)
How can I fix it and make this file "visible" to CLion?
If you are using fopen or something similar and just passing "data.txt", it is assumed that that file is in the current working directory of the running program (the one you just compiled).
So, either
Give a full path instead, like fopen("/full/path/to/data.txt"), where you use the actual full path
(not preferable), Move data.txt to the directory where CLion runs its compiled programs from.
(for #2, here's a hacky way to get that directory)
char buf[1024]; // hack, but fine for this
printf("%s\n", getcwd(buf, 1024));
Run/Edit configurations...
Select your application (on the lefthandside of the window)
Specify Working directory
Apply
Now you can fopen relatively from working directory.
I found another way to solve this problem.
#Lou Franco's solution may affect the project structure. For example, if I deploy code on a server, I should move the resource file to specific directory.
What I do is modify the CmakeLists.txt, on Windows, using
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "D:\\science\\code\\English-Prediction")
CMAKE_RUNTIME_OUTPUT_DIRECTORY is a CMake variable, it assigns the work directory of CLion work directory.
Continuing with the CMAKE_RUNTIME_OUTPUT_DIRECTORY CMakeLists variables, I do the following. In the root directory of my project, I create a directory, e.g., out. Then, in my CMakeLists.txt I set the CMAKE_RUNTIME_OUTPUT_DIRECTORY to that directory:
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/out)
Note, that must come before you have
add_executable(YourProject ${SOURCE_FILES})
I might also add that instead of using fopen() I would keep it more object-oriented by using std::ifstream:
std::ifstream inFile("data.txt");
// check if it opened without issue...
if (!inFile) {
processError(); // a user-defined function to deal with the issue
} else {
// All is good, carry on...
// and when you're done don't forget
inFile.close();
}
Is it possible to tell ASDF that it should produce only one fas(l) file for entire system? This file should be concatenation (in right order) of all compiled files of the system, including all files of systems on which target system depends.
Yes, with compile-bundle-op (ASDF 3.1): http://common-lisp.net/project/asdf/asdf/Predefined-operations-of-ASDF.html
edit: Actually, monolithic-compile-bundle-op seemes to be asked for (as shown in other answers).
If you have to predict the extension, use uiop:compile-file-type.
And/or you can just call (asdf:output-files 'asdf:monolithic-compile-bundle-op :my-system) to figure out what is actually used.
Option monolithic-compile-bundle-op will create single compiled file which includes all dependencies, while compile-bundle-op creates a file for every system.
Example of use:
(asdf:operate 'asdf:monolithic-compile-bundle-op :my-system)
This command will create file my-system--all-systems.fas(l) in output directory of target project, as well as "bundle" files for every system, named like my-system--system.fas(l).
So I am trying to compile Pascal programs and everything is find; however, I would like to put the generated files after each compilation is a separated folder. I am looking of something like this: fpc "Destination Folder" "program.pas".
Thanks
From Alphabetical listing of command line options
-FE<x> Set exe/unit output path to <x>
-FU<x> Set unit output path to <x>, overrides -FE
So something like fpc program.pas -FEc:\output should work. I don't have fpc installed so I cannot verify. If you try it and get errors that you can't work through post them.
This one works for me:
fpc hello.pas -o"Web/hello.cgi"
I was using ubuntu, notice there is no space between the argument -o and the beginning of the path "Web/..."
In the Emperor project, I'm having some issues getting intltool to work when doing an out-of-tree build. When running make check out-of-tree, which is one of the things make distcheck does, intltool fails thus:
INTLTOOL_EXTRACT="/usr/bin/intltool-extract" XGETTEXT="/usr/bin/xgettext" srcdir=../../po /usr/bin/intltool-update --gettext-package emperor --pot
can't open ../../po/../data/emperor.desktop.in: No such file or directory at /usr/bin/intltool-extract line 212.
intltool is looking for emperor.desktop.in, which is listed in po/POTFILES.in, in the source tree. However, emperor.desktop.in is generated by the configure script from a file called emperor.desktop.in.in, in order to insert the installed executable path as configured by the user, and lands in the build tree.
These are the relevant bootstrap.sh lines:
echo +++ Running intltoolize ... &&
intltoolize --force --copy &&
cat >>po/Makefile.in.in <<EOF
../data/_column_names.h:
cd ../data && \$(MAKE) _column_names.h
EOF
The setup code in configure.ac:
IT_PROG_INTLTOOL([0.35.0])
GETTEXT_PACKAGE=emperor
AC_SUBST(GETTEXT_PACKAGE)
AC_DEFINE_UNQUOTED([GETTEXT_PACKAGE], ["$GETTEXT_PACKAGE"],
[The domain to use with gettext])
AM_GLIB_GNU_GETTEXT
data/emperor.desktop.in is listed in AC_CONFIG_FILES.
data/Makefile.am contains these lines:
desktopdir = $(datadir)/applications
desktop_in_files = emperor.desktop.in
desktop_DATA = $(desktop_in_files:.desktop.in=.desktop)
#INTLTOOL_DESKTOP_RULE#
and po/POTFILES.in contains the line
data/emperor.desktop.in
You can review all the details in the public git repository if you wish.
Can I somehow tell intltool that this file will be located in the build tree, not in the source tree? Otherwise, my options appear to be to break make distcheck (not a great option), or to ship a desktop file that doesn't include the full path and assumes that the executable is installed in the PATH. (just as messy, IMHO) - Any other options?
In your source code you have emperor.desktop.in.in, which does not seem to be in any rule as a dependency. That file has to be converted first to emperor.desktop.in and later to emperor.desktop, which does not seem to be the case in your data/Makefile.am.
desktopdir = $(datadir)/applications
desktop_in_in_files = emperor.desktop.in.in
desktop_in_files = $(desktop_in_in_files:.desktop.in.in=.desktop.in)
desktop_DATA = $(desktop_in_files:.desktop.in=.desktop)
#INTLTOOL_DESKTOP_RULE#
[...]
EXTRA_DIST = \
$(desktop_in_in_files) \
[...]
$(desktop_in_in_files) contains $(desktop_in_in_files), and Makefile will know how to deal with that.
Some further digging has brought me believe that the answer is: intltool does not support source files that aren't source files in the project. Ergo, any additional processing must be done after intltool is through
Intltool requires the lines in POTFILES to be relative to the (build-time) working directory. The file POTFILES is generated by the configure script from POTFILES.in with a simple sed script defined in the IT_PO_SUBDIR autoconf macro (called by IT_PROG_INTLTOOL) that simply prepends the relative location of the top-level source directory to the paths. Alas, modifying POTFILES does not help: the intltool-extract script does everything it can to get the source directory right. I don't believe files that are sometimes inside and sometimes outside the source tree can be supported without modifying intltool itself.
