%general-entities; ]> $LastChangedBy$ $Date$ GDB GDB, the GNU Project debugger, allows you to see what is going on inside another program while it executes -- or what another program was doing at the moment it crashed. Note that GDB is most effective when tracing programs and libraries that were built with debugging symbols and not stripped. &lfs83_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &gdb-md5sum; Download size: &gdb-size; Estimated disk space required: &gdb-buildsize; Estimated build time: &gdb-time; GDB Dependencies Optional (required for tests), , (ada and gfortran are used for tests), , , (used for some tests), , and SystemTap (run-time, used for tests) User Notes: Install GDB by running the following commands: ./configure --prefix=/usr --with-system-readline && make Optionally, to build the API documentation using , run: make -C gdb/doc doxy To test the results, issue: pushd gdb/testsuite && make site.exp && echo "set gdb_test_timeout 120" >> site.exp && runtest TRANSCRIPT=y popd See gdb/testsuite/README and TestingGDB. There are many problems with the test suite: Clean directories are needed if re-running the tests. For that reason, it is recommended to make a copy of the compiled source code directory before the tests in case you need to run the tests again. Results depend on installed compilers. There are a large number of timeouts (there is a variable that can be set to increase time for timeout, but changing it will result in a different number of tests being run). There are failures associated with system readline 6.x. A few tests assume that the header file <sys/sdt.h>, part of SystemTap, is present. Approximately 1-3% of the tests fail (out of over 53000 tests). Now, as the root user: make -C gdb install If you have built the API documentation, it is now in gdb/doc/doxy. You can install it (as the root user): install -d /usr/share/doc/gdb-&gdb-version; && rm -rf gdb/doc/doxy/xml && cp -Rv gdb/doc/doxy /usr/share/doc/gdb-&gdb-version; --with-system-readline: This switch forces GDB to use the copy of Readline installed in LFS. Installed Programs Installed Library Installed Directories gcore, gdb and gdbserver libinproctrace.so /usr/{include,share}/gdb and /usr/share/doc/gdb-&gdb-version; Short Descriptions gcore generates a core dump of a running program. gcore gdb is the GNU Debugger. gdb-prog gdbserver is a remote server for the GNU debugger (it allows programs to be debugged from a different machine). gdbserver libinproctrace.so contains functions for the in-process tracing agent. The agent allows for installing fast tracepoints, listing static tracepoint markers, probing static tracepoints markers, and starting trace monitoring. libinproctrace.so
