shared-libraries

I'm trying to dynamically load a camera library .so file into a Linux executable to gain access to simple camera functions. I'm attempting to do this by: if ( (newHandle = dlopen("./libCamera.so",RTLD_LAZY | RTLD_GLOBAL)) == NULL ) { printf( "Could not open file : %s\n", dlerror() ); return 1; } However this fails and I receive the following output: "Could not open file : libCamera.so: undefined symbol: ZTVN10 _cxxabiv117__class_type_infoE" How do I find out what symbols it is relying on? Most likely, libCamera.so uses a symbol defined in a shared library without depending on that library.

EDIT: I suppose I should clarify, in case it matters. I am on a AIX Unix box, so I am using VAC compilers - no gnu compilers. End edit I am pretty rusty in C/C++, so forgive me if this is a simple question. I would like to take common functions out of a few of my C programs and put them in shared libraries or shared objects. If I was doing this in perl I would put my subs in a perl module and use that module when needed. For the sake of an example, let's say I have this function: int giveInteger() { return 1034; } Obviously this is not a real world example, but if I wanted to share that

I am trying to load two shared libraries in my Android application through the loadLibrary call: System.loadLibrary("mywrapper"); System.loadLibrary("crypto"); I keep running catching the `UnsatisfiedLinkError. Here is a more detailed version of the error. Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1969]: 130 could not load needed library 'libcrypto.so.1.0.0' for 'libmywrapper.so' (load_library[1111]: Library 'libcrypto.so.1.0.0' not found) Any ideas? After spending some time I found out that Android doesn't support versioned libraries. Has any one faced the

TL;DR Is there a way to import code into the Jenkinsfile from the local repository (other than the load step)? Why? I've experienced that for complex builds the Jenkinsfile gets kind of bulky and not very maintainable. Now that the build job is code, it would be wonderful to have the same means as for other code. That is, I would like to divide it into smaller (more maintainable) units and unit test them. What I tried shared libraries : allow for dividing our Jenkins Pipeline logic into smaller files in a separate module and even unit test it. However, they need to be in different repository

We have a web application made in Java, which uses struts2, spring and JasperReport. This application runs on glassfish 4.0. The libraries of the application are in the WEB-INF/lib folder, and also in glassfish are installed 4 more than uses the same libraries. Glassfish is configured to use 1024mb for heapspace and 512m for permgen, and the most of the memory consumption when i use libraries per application is in the struts actions and spring aop classes (using netbeans profiler). The problem we are having is the amount of memory consumed by having libraries in the classloader per application

I need to use different dynamic library over a execution cycle of a program. Looking at dlfcn.h I thought this was possible. I confess of not reading much literature on dynamic library loading. OK here is what I do - I have created shared library called `libdynamicTest.so.1` The main APP opens this solib ( dlopen ), gets the function pointer ( dlsym ), run it and then close it back ( dlclose ) Everything is fine until here. Now suppose I replace my libdynamicTest.so.1 by another libdynamicTest.so.1 (some code diff) I see a Segmentation fault. Further I have made sure the solib is replaced

The theano installation documentation states, that theano will as a default use the BLAS libraries from numpy, if the "BLAS libraries are available as dynamically-loadable libraries". This seems not to be working on my machine, see error message. How do I find out, if the numpy BLAS libraries are availalbe as dynamically-loadable? How do I recompile the numpy BLAS libraries, if they are not dynamically-loadable? Please indicate, if you would need more information! Error message We did not found a dynamic library into the library_dir of the library we use for blas. If you use ATLAS, make sure
