when i am doing make in /opencv/build directory it is working upto some extent after that it is showing this kind of error what should i do
Linking CXX executable ../../bin/opencv_test_core
CMakeFiles/opencv_test_core.dir/test/ocl/test_arithm.cpp.o: file not

Your problem is most likely here:
CMakeFiles/opencv_test_core.dir/test/ocl/test_arithm.cpp.o: file not recognized: File truncated
Delete the object (.o) file and rerun. The make call was probably interrupted before which caused the object file to be truncated.

Building webassembly with opencv

I've been trying to build a piece of code in webassembly that would use OpenCV.
I took https://github.com/mpizenberg/emscripten-opencv to start building, this worked well, but when I try adding cv::resize to be able to resize an image, that's when I have some issues:

I tried wrapping up my problem here https://github.com/jdrouet/opencv-wasm, you can pull it and run make, it'll build with docker.
Do you have any idea of how I could fix my issue?
Ok, looks like I found a way to build it (still here https://github.com/jdrouet/opencv-wasm) but now, when I try to use the resize function, I end up with the following error :
Error: the string "174007712 - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch." was thrown, throw an Error :)
So now, I don't know if I'm not using the function well... Here is the function : https://github.com/jdrouet/opencv-wasm/blob/master/source/resizer.cpp#L23
Do you have any idea of why it's not working?

Using Clang to get function definitions

I would like use clang to get the functions names from a cpp file.
I found some tutorials but always I received this error when I executed 'make':
/usr/bin/ld: error: ../../lib/libLLVMSelectionDAG.a: ELF section name out of range
collect2: error: ld returned 1 exit status
tools/lto/CMakeFiles/LTO.dir/build.make:269: recipe for target 'lib/libLTO.so.7.0.0svn' failed
make[2]: * [lib/libLTO.so.7.0.0svn] Error 1
CMakeFiles/Makefile2:18957: recipe for target 'tools/lto/CMakeFiles/LTO.dir/all' failed
make[1]: * [tools/lto/CMakeFiles/LTO.dir/all] Error 2
Makefile:149: recipe for target 'all' failed
make: *** [all] Error 2
Any idea of how can I solve this problem or any tutorial?
Thanks in advance.
I solved the problem increasing the /dev/sda1 size and removing the file ../../lib/libLLVMSelectionDAG.a
After that I only executed 'make' and It worked.

Permission denied error when running simple c++ program

I get this error almost everytime i try to run a simple code on CLion.
I'm not trying to save the project in c drive.

This usually means your program is already running. You can't replace it with a new one while it's running. Ensure you've closed your program before you try to rebuild it. If you think you've done so, there may be a bug where it is hanging — attach your debugger to find out.

make "sumo 0.17.1" on ubuntu 13.10

I installed and tested v0.19.1 successfully before, however, I needed to downgrade to 0.17.1 in order to run some example in omnetpp's veins simulator.
Whenever I run the "make" command, I get the following error:
/usr/bin/ld: ./utils/foxtools/libfoxtools.a(MFXMutex.o): undefined reference to symbol 'pthread_mutexattr_settype##GLIBC_2.2.5'
/lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/maamoun/pkgs/sumo-0.17.1/src'
make: *** [all-recursive] Error 1
What am I missing?!
Problem solved, had to install libproj-dev and include proj in the ./configure using the --with-proj-includes=DIR
[EDIT] after 15 minutes of making, same error raised again!!!

Cannot find library reference to libmysqlclient_r Angstrom

I downloaded the MySQL Connector / C++ code from dev.mysql.com. I also used opkg to download the libmysqlclient-r-dev package, which gave me libmysqlclient_r.so and .la in my /usr/lib directory.
When I attempt to make the source code for the MySQL connector, I get the following error:
/usr/lib/gcc/arm-angstrom-linux-gnueabi/4.7.3/../../../../arm-angstrom-linux-gnueabi/bin/ld: cannot find -lmysqlclient_r
collect2: error: ld returned 1 exit status
make[2]: *** [driver/libmysqlcppconn.so.1.0.5] Error 1
make[1]: *** [driver/CMakeFiles/mysqlcppconn.dir/all] Error 2
make: *** [all] Error 2
It tells me that the library is missing, eventhough it is present in /usr/lib?
How does that work, and what should I do?
