In some situations, atexit handlers perform I/O (e.g., closing a file), which entails the handling of signals. Should SIGTERM be pending, the handling of this signal will in turn trigger the execution of atexit handlers. To break this cycle, this patch removes atexit handlers from the list before executing them. So no atexit handler is entered more than once. Fixes #5444
This directory contains ports of 3rd-party libraries to Genode. Usage ----- The tool './tool/ports/prepare_port' in the toplevel directory automates the task of downloading and preparing the 3rd-party source codes. One can select individual ports that have to be prepared by specifying their base names (without the version number) as command-line argument. For example, the following command prepares both the C library and the Freetype library: ! ./tool/ports/prepare_port libc freetype To compile and link against 3rd-party libraries of the 'libports' repository, you have to include the repository into the build process by appending it to the 'REPOSITORIES' declaration of your '<build-dir>/etc/build.conf' file. Under the hood -------------- For each library, there is a file contained in the 'libports/ports/' subdirectory. The file is named after the library and contains the library-specific rules for downloading the source code and installing header files. How does 'libports' relate to the other repositories? ----------------------------------------------------- Most libraries hosted in the 'libports' repository expect a complete C library, which is provided via the 'libc' port. The libc, in turn, depends on the 'os' repository for its back end.
