| Summary | 0002562: 'extract' command fails due to default plugin path in Darwin | ||||
| Description | Compiling from tarball, after 'make install', the 'extract' command always returns empty results because plugins are not found. This problem did not exist in 0.6.3. The reason is due to the following Darwin specific code found in extractor_plugpath.c. Suppose I do a 'make install' to a typical prefix of '/usr/local'. The executable 'extract' will be installed at '/usr/local/bin'. In this case, the get_path_from_NSGetExecutablePath function returns '/usr/local/bin/libextractor' instead of '/usr/local/lib/libextractor', so it is unable to find any plugins. In addition, on Darwin, the '_NSGetExecutablePath' call may return a symbolic link, so if you configured the prefix to something like '/usr/local/X/' and symlink '/usr/local/X/bin/extract' to '/usr/local/bin/extract', the path from 'get_path_from_NSGetExecutablePath' will return the symbolic path '/usr/local/bin/libextractor', which is most probably wrong. A 'realpath' call can resolve this path to the real path. #if DARWIN if (NULL == prefix) prefix = get_path_from_NSGetExecutablePath (); if (NULL == prefix) prefix = get_path_from_dyld_image (); #endif | ||||
| Steps To Reproduce | ./configure --prefix=/usr/local make && make install extract -V src/plugins/testdata/png_image.png => No results | ||||
