[CMake] regarding linking functionality and overloading in cmake

[Leila Baghdadi]

yep that's how its defined. (note, this is not my code, it is backprojection code free for download at ctsim.org)

typedef double kfloat64;
typedef kfloat64** const ImageFileArrayConst;

the code has diversions between 32 and 64 bit, anyways, that's how it is defined.

Unless “ImageFileArrayConst” is a typedef for “double **”, there is not an ImageFile::statistics() function which takes a double** as the first parameter. (Line 288 and 296 have the two versions of ImageFile::statistics())
 
If you look in views.cpp at the function ImageFileView::OnProperties() function where it is calling the ImageFile::statistics() function, what is the type of the first parameter?  Do you have an extra & on the front of a double* variable there?

Hello

I have attached the CMakeLists.txt file (note, I commented the source in question line 76) and I get the following error, If I leave line 76 in, I get a clean build
Linking CXX executable opt_ctsim
CMakeFiles/opt_ctsim.dir/src/views.cpp.o: In function `ImageFileView::OnProperties(wxCommandEvent&)':
views.cpp:(.text+0x1bfd9): undefined reference to `ImageFile::statistics(double**, double&, double&, double&, double&, double&, double&) const'
views.cpp:(.text+0x1c57a): undefined reference to `ImageFile::statistics(double**, double&, double&, double&, double&, double&, double&) const'
collect2: ld returned 1 exit status

I am also attaching the source imagefile.cpp located in libctsim subdirectory.

thanks

This sounds like poorly formed c++, not a CMake issue.  Can you include your CMakeLists.txt, a copy of the error, and possibly a simple example which shows the problem?

hi everyone,

I have been trying to use cmake to build ctsim(need to add my own code to it later) and finally managed to do it however I have difficulty understanding why my puny solution works!

I have 3 different directories (a,b,c) in ctsim , so I set up cmake files in each one and built liba.so and so on,

now I am trying to build the executable cstim by linking to the above three libraries and I kept getting an error, regarding an overloading function in directory a,

I thought that using TARGET_LINK_LIBRARIES(target a b c) would address that but instead I had to add the source code with the overloading function from directory a into the list of source codes for the ctsim executable,

does that make sense? 

any thought 

thanks

Leila
