shared-libraries

I am using pip and trying to install a python module called pyodbc which has some dependencies on non-python libraries like unixodbc-dev, unixodbc-bin, unixodbc. I cannot install these dependencies system wide at the moment, as I am only playing, so I have installed them in a non-standard location. How do I tell pip where to look for these dependencies ? More exactly, how do I pass information through pip of include dirs (gcc -I) and library dirs (gcc -L -l) to be used when building the pyodbc extension ? pip has a --global-option flag You can use it to pass additional flags to build_ext . For

I have some code that uses some shared libraries (c code on gcc). When compiling I have to explicitly define the include and library directories using -I and -L, since they aren't in the standard places. When I try to run the code, I get the following error: ./sync_test ./sync_test: error while loading shared libraries: libsync.so: cannot open shared object file: No such file or directory However, do the following, everything works just fine: export LD_LIBRARY_PATH="/path/to/library/" ./sync_test Now, the strange part is, this only works once. If I try and run sync_test again I get the same

gcc and ld provide many ways to specify a search path for libraries—among them the -rpath and -L flags. The manpages reveal no differences between these two flags, effectively saying each flag adds a library to the library search path. Yet it seems strange that both flags do exactly the same thing. What are the differences, if any, between these two options? You must be reading some outdated copies of the manpages (emphasis added): -rpath=dir Add a directory to the runtime library search path. This is used when linking an ELF executable with shared objects. All -rpath arguments are

I am in the development of an Android library module which has to include Crosswalk Webview. I create the library using Github Sonatype ( https://github.com/sonatype/ ). It works fine without Crosswalk Webview. I tried the following 3 methods to include Crosswalk. Method 1: Add Crosswalk Webview library in my library project app gradle Error : (Compile error) Failed to resolve: org.xwalk:xwalk_core_library:18.48.477.13 Method 2: Add crosswalk aar file in my library project Reference link for adding aar file How to import a .aar file into Android Studio 1.1.0 and use it in my code I have
