I'm creating a static lib via cmake,and when I view the .a binary file with less/more/cat I see functions from my time_tools.c, but not my other_api.c The directories structure is:
Code:
CMakeLists.txt
time/CMakeLists.txt
time/time_tools.c
time/time_tools.h

I am attempting to compile some code on a cluster where I do not have root access (and is missing many of the libraries I want), and hence have had to create local builds of the boost and opencv libraries (i.e. in /home/username/usr/local). In particular, my cmake depends on:
Code:
find_package(boost)
which my normal development machine finds in:
Code:
/usr/share/cmake-2.6/Modules/FindBoost.cmake
On the cluster I have a version of FindBoost.cmake at:
Code:
/home/username/cmake_modules
How can I tell CMake to look for FindBoost.cmake in that directory, since neither the cmake file, nor the boost install is in the standard location? I've modified the FindBoost.cmake file to make it search in the locally installed boost libraries.

Only ones I can think of seem overly complex, and I'm sure there is a simple solution I am overlooking. I have a class, it has a member who is an object. This object needs to be able to represent an object of different types.
[code]...
Where "surface" could be several different types, which will be set during execution. Hope this is clear enough. I have tried using templates but am getting "data member cannot be a member template". Either I have incorrect syntax, or am not implementing it right. another solution would have one class containing definitions of all possible shapes, But this would take up extra memory. Other solutions I thought of seem too round-about, and seems there is a simpler solution that I have overlooked.
This is probably an easy question but somehow I couldn't manage it to work.. I was testing the C++ WT library and I have a CMakeLists.txt file as below:
Code:
ADD_EXECUTABLE(heloooo.wt
hello.C
)
SET(CMAKE_SKIP_BUILD_RPATH FALSE)

What am i doing wrong, I don't want to use the LD_LIBRARY_PATH, but to get the executable find the library with rpath when run?

Overnight, I upgraded from KDE 4.5.1 to 4.6.3 and had a rude awakening this morning when I found that KDE had managed to, once again, break the Task Manager "force rows" behavior which had been fixed a few major releases ago. I found this lovely patch that had been applied:
[URL]
And thus broken the functionality, and I want to recompile that particular plasmoid with the patch removed. However, I am completely unfamiliar with CMake or building anything at all, for that matter. All my programming is done in PHP which means I'm pretty much completely lost. I'm in the midst of pulling down the kde-workspace tree with git, and already downloaded and modified a separate copy of the file in question to look the way it is supposed to. I don't want to rebuild all of KDE, just the one module.
Is there any tool to translate rules from configure.ac into Cmake rules?

I have 2 completely different processes A and B (they do not have any relationship) suppose A opens a file with file descriptor 4 and B opens another file with file descriptor 5
Can process A use the fd 5 (i.e using the file object of processs B) by any means..if suppose i let the fd 4 of process A to point to the file object of process B(fd 5) will it work? is it safe?
Is there any way may be some tools to view and explore contents of .obj files (in a formatted or unformatted way) or an executable. Can we do it using gcc?

View 1 Replies View RelatedI have created an application that has a executable program that loads in a shared object
the shared object loads in another shared object
both of these shared object I have created
For debugging I have been printf'in data to determine what is going on
I now have some odd memory issue, and need a bit more control over debugging...
I have one workspace set up and under my exectuable(will call maintest from now on) I have two items in my link libraries under project build options being soA and soB (so A is the shared object that maintest uses, soB is the SO that soA uses) I also have linker options pthread and ldl
At the beginning of my maintest I do my dlsym and load in each function that I will be using
I always run my program using maintest, because when I have one of the SO as the startup project(turns bold) and try to run it gives me "You must select a host application to run a library"
I tried to set up this host library, i Go to Menu->Project->SetProgramArguments and change the Host Application to the debug version of my maintest
I then hit OK and try to run again but I get the same error: "You must select a host application to run a library"
If I get this part working - which I need help doing, is tehre other steps that need to be taken to debug the so's? or will this make it so when i hit f8 it will run.
What flags do you have to pass to valac to compile code into a shared library (file extension .so)?
View 1 Replies View RelatedI came from Windows and I am want to learn how C++ programs are compiled and executed in Linux. I read in "Thinking in C++" that the linker adds (by default) a startup module to the object files that an application should be made of. Now when I use g++, I can create an single object module out of a single source code file then execute it in the terminal like this:
./objectFile.out
How can this object file be executed while it doesn't contain the startup module? In Windows, object files usually get combined into an executable file (somthing.exe) then that executable can be executed, is this not necessary in Linux? does the OS perform required actions before it executes that object file?

why i am getting this error. I know the error is occuring because i have assigned values to obj.i and obj.j outside main(). But i want to know why do that result in an error. From my part i have created an object 'obj' of stucture 'test' and assigned values to its variables.
