In gcc 4.3 some bugs were fixed, unfortunately they can cause compile errors with code that would compile with older versions.\r\n\r\nIn particular this is the case with log4cpp 1.0 which fails with the following message:\r\nBasicLayout.cpp:37:5: error: ‘auto_ptr’ in namespace ‘std’ does not name a type\r\n\r\nLuckily the fix is very simple; all that is required to get a clean compile is add an #include <memory> in src/BasicLayout.cpp.\r\n
