I am trying to run a piece of code that includes "itkScalarImageTextureCalculator.h". However, cmake cannot find this reference, and I can't seem to find it manually neighter. I've looked for it in
Modules/Numerics/Statistics/include
Modules/Compatibility/V3Compatibility/include
Modules/Compatibility/Deprecated/include
but i can't find it anywhere. A search in the itk folder also returns no results. Was this library deleted/renamed/moved somewhere else? Or maybe there is some kind of problem with my itk installation? I have successfuly used other libraries, and I only have itk installed (I mean I don't have vtk, tcl etc).
It has been renamed itkScalarImageToTextureFeaturesFilter (probably in ITK 4.0). You can see this conversion listed in the table here: http://itk.org/Wiki/Proposals:Refactoring_Statistics_Framework_2007_Migration_Users_Guide

I think this is more of a Tcl configuration question rather than a Tcl coding question...
I inherited a whole series of Tcl scripts that are used within a simulation tool that my company built in-house. In my scripts, I'm finding numerous instances where there are function calls to functions that don't seem to be declared anywhere. How can I trace the path to these phantom functions?
For example, rather than use source, someone build a custom include function that they named INCLUDE. Tclsh obviously balks when I try to run it there, but with my simulation software, it runs fine.
I've tried grep-ing through the entire simulation software for INCLUDE, but I'm not having any luck. Are there any other obvious locations outside the simulation software where a Tcl function might be defined?
The possibilities:
Within your software. (you have checked for this).
Within some other package included by the software.
Check and see if the environment variable TCLLIBPATH is set.
Also check and see if the simulation software sets TCLLIBPATH.
This will be a list of directories to search for Tcl packages, and you
will need to search the packages that are located outside of the
main source tree.
Another possibility is that the locations are specified in the pkgIndex.tcl file.
Check any pkgIndex.tcl files and look for locations outside the main source tree.
Within an unknown command handler. This could be in
your software or within some other package. You should be able to find
some code that processes the INCLUDE statement.
Within a binary package. These are shared libraries that are loaded
by Tcl. If this is the case, there should be some C code used to
build the shared library that can be searched.
Since you say there are numerous instances of unknown functions, my first
guess is that you have
not found all the directories where packages are loaded from. But an
''unknown'' command handler is also a possibility.
Edit:
One more possibility I forgot. Check and see if your software sets the auto_path variable. Check any directories added to the auto_path for
other packages.
This isn't a great answer for you, but I suspect it is the best you're going to get...
The procedure could be defined in a great many places. Your best bet for finding it is to use a tool like findstr (on Windows) or grep -R (on POSIX platforms) to search across all the relevant source files. But that still might not help! It might not be a procedure but instead a general command, which could be implemented in C and not as a procedure, or it could be defined in a packaged application archive (which are usually awkward to look inside). There are also other types of script-implemented command too, which could make things awkward. Generally searching and investigating is your best bet, but it might not work.
Tcl doesn't really differentiate strongly between different types of command except in some introspection operations. If you're lucky, you could find that info body tells you the definition of the procedure (and info args and info default tell you about the arguments) but that won't help with other command types at all. Tcl 8.7 will include a command (info cmdtype) that would help a lot with narrowing down what to do next, but that's no use to you now and it definitely doesn't exist in older versions.
I have a Cython extension which I've compiled on Ubuntu 14 and uploaded as an Anaconda package. I'm trying to install the package on another machine which is running Scientific Linux (6?) which ships with an older version of glibc. When I try to import the module I get an error that looks (something like) this:
./myprogram: /lib/libc.so.6: version `GLIBC_2.14' not found (required by ./myprogram)
When I say "something like" - the "myprogram" is actually the .so name of the extension.
From what I understand this error is because I have a newer version of glibc on the build system which has an updated version of the memcpy function.
This page has a good description of the problem, and some rather impractical solutions: http://www.lightofdawn.org/wiki/wiki.cgi/NewAppsOnOldGlibc
There is also a much simpler answer proposed here: How can I link to a specific glibc version?
My question is: how to I apply this solution to my Cython extension? Assuming the __asm__ solution works (as given in the second link) what's the best way to get it into the C generated by Cython?
Also, more generally, how to other modules avoid this issue in the first place? For example, I installed and ran a pre-built copy of numpy without any issues.
This turned out to be quite simple.
Create the following header, glibc_fix.h:
__asm__(".symver memcpy,memcpy#GLIBC_2.2.5")
Then include it by using CFLAGS="-include glibc_fix.h". This can be set as an environment variable, or defined in setup.py.
Additionally, it turns out numpy doesn't do anything special in this regard. if I compile it myself it links with the newer version on my system.
I am new to TCL and trying to dig the C code that runs TCL commands , I installed TCL in windows . Not able to find the C code .
Can anyone suggest me where can I get the C code ? or any links ?
For browsing, see here on core.tcl.tk which is a web view into the code repository. The directories you're most likely to want to look inside are generic (platform-independent code, most of Tcl) and win (Windows-platform code, build instructions). The other main directories there are unix (Unix-specific sources), mac (Mac-specific build system), library (Tcl library files; no C code) and doc (documentation in a format that you've probably never encountered before).
For code relating to a specific version of Tcl, see the Tcl file distribution area on SourceForge. Pick your version, download the exact sources you want. Note that they'll be laid out in virtually the same way as in the repository: look in generic and win to see the C code.
You are new to Tcl and yet, you go for the C source code already? What is your goal? Are you trying to learn Tcl, or learn C? Any way, the source can be found here:
http://tcl.sourceforge.net/
After quite a bit of searching and trying different things, I am stumped on how to get mym to work (as found here: http://sourceforge.net/projects/mym/). I was wondering if anyone has a very simple list of actions needed to get this to work. I think my main trouble is installing zlib. I don't understand how to actually install it or work with it. I have tried to use Microsoft Visual C++ Express 2010 but then only the debug versions are compiled. That means when I try to use the mex function in matlab it gives me the error:
Error: Could not detect a compiler on local system
which can compile the specified input file(s)
I just don't understand the process and everywhere I look it says something different. I have tried multiple versions of each all of the programs involved and nothing seems to work. Any help would be greatly appreciated.
Do:
mex -setup
from the command line to define your compiler on your system. Once you do that then Matlab will correctly locate the compiler and build the mex libraries it needs.

I'm trying to translating the MySql C connector 6.02 headers to D, but I get some weird crashes.
My guess is I've made some mistakes on translating the structs or function (I'm not very good at C).
I used implib /system on the libmysql.dll to create a lib file.
I couldn't get htod.exe to work. Using -hs (include system files) complained it couldn't find system files.
Coffimplib.exe didn't have an option to prepend _ to exported internal names.
I couldn't find a free version of coff2omf.
mysql.d is the wrapper. I've included the C definition before each wrapped definition to easier spot bugs. The file includes the mysql dll and converted libfile too.
When compiling mytest_fails.d it crashes. mytest_works.d only has an assert, and this makes it work.. Compiling mytest_works with -release makes it crash too.
I've been using dmd 2.051
Download mytest.zip from share1t.com
Update: I've also asked some question regarding this on the D.learn newsgroup, but I don't think anyone has gone through the code.
C Const
Compiler extensions
Connot get htod.exe to work
The weird crashes
stdcall is a Windows function calling convention (very different from the C calling convention). HTOD failed to mark several functions with extern(Windows). This is normal, since HTOD isn't equipped to handle macros (STDCALL is defined as a macro, I can see that from the leftover comments in msyql.d).
Here's an updated mysql.d file:
http://dl.dropbox.com/u/9218759/mysql.d
Now, you need the proper import library in OMF format. I'd generally advise that you do not use implib for this. I've had several problems with it and others have reported having problems using it. Using coffimplib is the way to go. But first, you will need a COFF import library.
If you need it, the Mysql release with the COFF import library can be downloaded from here: http://dev.mysql.com/downloads/mirror.php?id=377977#mirrors (Libraries in DLL form marked for Visual Studio usually come with a COFF import library).
But I'm providing you the translated COFF import library in OMF format here: http://dl.dropbox.com/u/9218759/libmysql.lib
I've tried both of your test cases and they both seem to work fine now. In case of problems, try to check the translated header file again (mysql.d), it's possible that I might have missed to specify all the calling conventions properly.
