Greeting Everyone!
I am a student and currently I got problem in setting Code Block.
Can anyone help me or guide me how to configure Code Block so it can run MPI?
I already install Code Block and MPICH2.
But when I trying to compile the code, it does not work. Code block doesn't detect MPI.
Anyone can show to me step by step to configure it.
Really Appreciate it :)
I assume you are asking about Code::Blocks IDE.
I think, you should modify your IDE and project settings and switch from default GCC compiler setup to MPI one.
First your should to clone GCC Compiler Setup in IDE Settings (menu "Settings" -> "Compiler and debugger"). http://www.codeblocks.org/docs/main_codeblocks_en3.html#x3-270001.11.6 You must clone the some complier settings (I recommend to copy a default "GNU GCC Compiler"), then you can change new settings set on the tab "Toolchain executables" -- replace the gcc and g++ by mpicc and mpicxx.
Second step is to change your MPI project build settings to use new compiler settings.
This will allow you to build MPI applications with Code::Blocks IDE.
To run them you can use the command line, and to debug them... debugging of MPI is not so easy...
Use Eclipse PTP. It has builtin support for MPI based programs.

I am trying to install a C++/Qt/Qml program with CMake. I tried the IFW generator, but I'd rather stick to NSIS64.
Setup install file is correctly generated, and program is correctly installed. But my installed Qt program crashes right away, because
qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
It is an easy to solve problem when running the program from the command line: we just need to set QT_QPA_PLATFORM_PLUGIN_PATH to the current directory (I installed/copied qwindows.dll there).
It is strange that the .exe does not look into the current program directory for Qt plugins. Anyways, a way to solve my problem would be: how to set an environment variable in a shortcut .lnk (created by NSIS)?
I have tried a bunch of things with NSIS (added in NSIS.template.in):
CreateShortCut "$SMPROGRAMS\$STARTMENU_FOLDER\#CPACK_NSIS_DISPLAY_NAME#.lnk" "QT_QPA_PLATFORM_PLUGING_PATH=$INSTDIR\bin $INSTDIR\bin\#CPACK_NSIS_DISPLAY_NAME#.exe"
CreateShortCut "$SMPROGRAMS\$STARTMENU_FOLDER\#CPACK_NSIS_DISPLAY_NAME#_cmd.lnk" \
"C:\Windows\System32\cmd.exe" "/c SET QT_QPA_PLATFORM_PLUGING_PATH=$INSTDIR\bin && start $INSTDIR\bin\#CPACK_NSIS_DISPLAY_NAME#.exe"
but this does not compile.
Maybe there is a different way to achieve this. Even if that would work, I would like to avoid setting QT_QPA_PLATFORM_PLUGING_PATH globally during the install, if possible, and restrain it to the program launch.
NOTE: documentation says:
CreateShortcut "$SMPROGRAMS\My Company\My Program.lnk" "$INSTDIR\My Program.exe"
"some command line parameters" "$INSTDIR\My Program.exe" 2 SW_SHOWNORMAL
ALT|CONTROL|SHIFT|F5 "a description"
but I am not too sure about how to use this in my case.
Has anyone enabled the libLTO when compiling the FreeBSD kernel(in order to compute a whole-program call graph). I want to compile the FreeBSD kernel using the libTO tool from the llvm/clang compiler suite. If anyone has previously done this work then can anyone show me how it is done or how to proceed to do it?
Wiki page called Building FreeBSD with Clang has a section regarding this. According to it, it's possible to perform LTO on kernel and get bootable binary. The page itself is somewhat old though, for example you don't need setenv CC clang step anymore, so your mileage may wary.
I'm trying to add Coverity Scan static analysis to my Qt project but I'm not able to get the result.
I download the coverity scan build tools and use the following command line:
cov-build --dir cov-int make
Which produces the following log:
...
my build log
...
[WARNING] No files were emitted. This may be due to a problem with your configuration
or because no files were actually compiled by your build command.
Please make sure you have configured the compilers actually used in the compilation.
For more details, please look at:
/Users/martin/dev/builds/ConsoleTest01-Desktop_Qt_5_3_clang_64bit-Debug/cov-int/build-log.txt
How can I go further?
I'm using Qt 5.3.2 under MacOS 10.9.
I didn't read the docs carefully enough: https://scan.coverity.com/download?tab=cxx
I had to configure coverity first by running:
cov-configure --comptype clangcxx --compiler clang++ --template
You need to run qmake first, then you can run the cov-int command with make.
I found it easiest to run cov-int in my build- folder created by Qt-Creator.
How to change compiler executable name? I want to perform a "fake build" of some products which are using BJam as build system. (For example: the Boost itself) In this "fake build" I want some special command to be called instead of g++. (with all the options and environment used in real build with real gcc).
How to perform this? Are there any command line switches which already allows me to do what I need or maybe I can somehow modify *.jam files to achieve what I need?
The easiest thing might to just switch your path so gcc refers to what you want to run. Otherwise, the correct way to do it bjam is more finicky. I've never gotten it to successfully, easily work, but here's what the docs suggest:
You'll need to add command to the Jamroot of your project to configure the gcc mocking command. The simplest way is just:
using gcc : : my-gcc ;
But most likely you have another using gcc ; line somewhere in your jam rules (or site-config.jam) and you'll get a complaint about trying to reinitialize a toolset. If so, you'll need to give an explicit version to the toolset like so
using gcc : mywrapper : my-gcc ;
And to use this toolset when compiling use the command bjam toolset=gcc-mywrapper.
Good luck.
I'm trying to build an application from source in windows that requires some Unix tools. I think it's the apparently standard ./configure; make; make install (there's no INSTALL file). First I tried MinGW but got confused that there was no bash, autoconf, m4, or automake exes in \bin. I'm sure I missed something obvious but I installed Cygwin anyways just to move forward. For some reason when I run
sh configure.sh
I get:
platform unix
compiler cc
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
My OS has identity problems. Obviously the makefile is all wrong since I'm not on unix but win32. Why would the configure script think this? I assume it has something to do with Cygwin but if I remove that I can't build it at all. Please help; I'm very confused.
Also is it possible to build using MinGW? What's the command for bash and is mingw32-make the same as make? I noticed they're different sizes.
Everything is fine. When you are inside CygWin, you are basically emulating an UNIX. sh runs inside CygWin, and thus identifies the OS correctly as Unix.
Have a look at GCW - The Gnu C compiler for Windows
Also, you might be interested in this help page, that goes into some detail about the minimal system (MSYS), such as how to install, configure et. c.
That should help you get bash, configure and the rest to work for MinGW as well.
From the Cygwin home page
Cygwin is a Linux-like environment for Windows. It consists of two parts:
A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
A collection of tools which provide Linux look and feel.
Since configure is using the Cygwin environment, it is interacting against the emulation layer and so it is just like it's working on a Unix environment.
Have you tried building the application and seeing if it works?
