Hi I'm trying to compile libstdc++-v3 with debugging symbols and I'm a little stuck. I'm trying to follow the documentation `/libstdc++-v3/doc/html/manual/setup.html' and I'm not finding it very clear what I'm supposed to do if I want to ONLY build libstdc++-v3 and NOTHING else. So far I have 1. Downloaded the entire source tree of the gcc project via svn $ svn checkout svn://gcc.gnu.org/svn/gcc/trunk gcc-root 2. The documentation seems to strongly recommend that my code is NOT compiled in the source directory so I did the following. $ mkdir gcc-build $ cd gcc-build 3. Now here's where I get confused the documentation says "When configuring libstdc++, you'll have to configure the entire gccsrcdir directory." Isn't that going to build everything though? I don't want to do that. Surely I want to run $ ../gcc-root/libstdc++-v3/configure --enable-libstdcxx-debug --prefix=$HOME/local and NOT (as the documentation suggests) $ ../gcc-root/configure --enable-languages=c++ --enable-libstdcxx-debug --prefix=$HOME/local anyway I ran `../gcc-root/libstdc++-v3/configure --enable-libstdcxx-debug --prefix=$HOME/local'. All the checks passed a make file was generated in my current directory (gcc-build). $ ls config.h config.log config.status doc include libsupc++ libtool Makefile po python scripts src stamp-h1 testsuite 4. I tried running make $ make and the build fails. The output is shown here http://pastebin.com/p4iD7h4i The reason I'm trying to do this is so I can build programs on my system and debug the standard library objects. For example when in gdb if I try to do the following gdb) call cout.good() Couldn't find method std::ostream:;good I presume this error message is because my version of libstdc++ has no debugging symbols. I did try compiling with `-D_GLIBCXX_DEBUG' and for someone reason that I can't explain that made some standard library objects I declared in the stack accessible via gdb (e.g. if I had an ifstream object called inputFile) despite the fact my version of libstdc++ has no debugging symbols at all! gdb) call inputFile.good() $1 = true Without that compiler flag I can't seem to call any of the methods on standard library objects my code creates. What am I doing wrong? Thanks.
