[llvm-dev] llvm build failed while Linking CXX shared library ../../../lib/libc++.so
Hello everybody, I am very new to llvm and I am struggling to install it on my 15.10 Xubuntu with kernel 4.2.0-34-generic #39-Ubuntu SMP x86_64 GNU/Linux. I essentially intend to use the clang static analyzer, but it seems that I have to build it on top of llvm and clang. Unfortunately I run into the following problem. CXX shared library ../../../lib/libc++.so at around 52% of the procedure (while building target gtest_main) followed by a handful of undefined references the last lines consist of the following messages: collect2: error: ld returned 1 exit status projects/libcxx/lib/CMakeFiles/cxx.dir/build.make:735: recipe for target 'lib/libc++.so.1.0' failed make[2]: *** [lib/libc++.so.1.0] Error 1 CMakeFiles/Makefile2:11552: recipe for target 'projects/libcxx/lib/CMakeFiles/cxx.dir/all' failed make[1]: *** [projects/libcxx/lib/CMakeFiles/cxx.dir/all] Error 2 Makefile:136: recipe for target 'all' failed make: *** [all] Error 2 Can someone please help me go further? -------------- next part -------------- An HTML attachment was scrubbed...

Hi Ioannis, If you only want the clang static analyzer, there is no need to check out and build libc++ as part of the process. The rest of the build can just use the system C++ library, which will be libstdc++ on Xubuntu. That said, without the full build log, it is hard to say what went wrong. Specifically, which references were undefined? -Dimitry> On 26 Mar 2016, at 16:04, Ioannis Koukoulis via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Hello everybody, > > I am very new to llvm and I am struggling to install it on my 15.10 Xubuntu with kernel 4.2.0-34-generic #39-Ubuntu SMP x86_64 GNU/Linux. > > I essentially intend to use the clang static analyzer, but it seems that I have to build it on top of llvm and clang. > > Unfortunately I run into the following problem. > CXX shared library ../../../lib/libc++.so > at around 52% of the procedure (while building target gtest_main) > followed by a handful of undefined references > > the last lines consist of the following messages: > collect2: error: ld returned 1 exit status > projects/libcxx/lib/CMakeFiles/cxx.dir/build.make:735: recipe for target 'lib/libc++.so.1.0' failed > make[2]: *** [lib/libc++.so.1.0] Error 1 > CMakeFiles/Makefile2:11552: recipe for target 'projects/libcxx/lib/CMakeFiles/cxx.dir/all' failed > make[1]: *** [projects/libcxx/lib/CMakeFiles/cxx.dir/all] Error 2 > Makefile:136: recipe for target 'all' failed > make: *** [all] Error 2 > > Can someone please help me go further? > > > _______________________________________________ > LLVM Developers mailing list > llvm-dev at lists.llvm.org > http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev-------------- next part -------------- A non-text attachment was scrubbed...

Hi Dimitry, I do not particularly need to build libc++ from the package. Is the name of the package's libc++, libcxx, because this is where the installation starts finding undefined references, during linking CXX shared library ../../../lib/libc++.so. Please check below the first part of the log when the first error appear, I omited repeating results. Furthermore, the undefined references are thousands! If you say that libc++ is not need it how can I skip it's interference. Shall I check out the package again without the particular libc++, of invoke cmake with a particular parameter? . .
