And/or during the build LD_LIBRARY_PATH is used to change the link path, so running ldd like above doesn't give the same results as what would happen when you run something using libuno_sal.so e.g. [caolan@Nom core]$ ldd install/ure/lib/libuno_sal.so.3 libstdc++.so.6 = /home/caolan/LibreOffice/core/install/ure/lib/libstdc ++.so.6 (0x7fc9fa177000) libgcc_s.so.1 = /home/caolan/LibreOffice/core/install/ure/lib/libgcc_s.so.1 i.e. my copy of libstdc++.so.6 is the one that will get used when I run the final binaries. That's why I'm plinking around the issue of the libstdc++.so.6 which gets copied/created by the external module to see if the libstdc++.so.6 that's in there is the right one. You could play around with LD_DEBUG=man-page-options and see if that gives anything useful. Have others had any issues compiling LO with GCC 4.6? It's frustrating and telling that I'm the only one noticing it. Nope, I build with it all the time. However my gcc 4.6 and stdc++ are the system ones, and not in /usr/local/somewhere C. ___ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice

I still don't know exactly why the compilation fails with GCC v4.6 (compiled three weeks ago) yet doesn't with GCC v4.4, but I can fix it one of two ways: - $ hash -r $ which gcc g++; gcc --version | head -1; g++ --version | head -1 /usr/local/bin/gcc /usr/local/bin/g++ gcc (GCC) 4.6.1 g++ (GCC) 4.6.1 # fails $ gcc -o .../oosplash [...] # works; rest of build can now finish successfully $ gcc -o .../oosplash [...] -lstdc++ or $ g++ -o .../oosplash [...] - Have others had any issues compiling LO with GCC 4.6?

[Libreoffice] gcc/g++ compilation issue in desktop/splash
Hi Folks, I haven't seen a fix go by, and have seen nothing mentioned on the list regarding building the splash part of desktop, but I'm having an issue that appears to be solved by switching to g++ instead of gcc: - $ cd desktop $ build [...snip...] Entering /home/kevin/devel/libreoffice/desktop/unx/source Making:oosplash ccache /usr/local/bin/gcc -Wl,-z,noexecstack -Wl,-z,combreloc -Wl,-z,defs -Wl,-Bsymbolic-functions -Wl,--dynamic-list-cpp-new -Wl,--dynamic-list-cpp-typeinfo -Wl,--hash-style=gnu -g -g -Wl,-rpath,'$ORIGIN:$ORIGIN/../basis-link/program:$ORIGIN/../basis-link/ure-link/lib',--enable-new-dtags -Wl,-export-dynamic -Wl,-rpath-link,../../unxlngx6/lib:/home/kevin/devel/libreoffice/solver/350/unxlngx6/lib:/lib:/usr/lib -L../../unxlngx6/lib -L../lib -L/home/kevin/devel/libreoffice/solenv/unxlngx6/lib -L/home/kevin/devel/libreoffice/solver/350/unxlngx6/lib -L/home/kevin/devel/libreoffice/solenv/unxlngx6/lib ../../unxlngx6/obj/splashx.o ../../unxlngx6/obj/start.o ../../unxlngx6/obj/args.o ../../unxlngx6/obj/pagein.o ../../unxlngx6/obj/file_image_unx.o \ -lpthread -Wl,--as-needed -lXext -lX11 -Wl,--no-as-needed -luno_sal -lpng12 -lXinerama -o ../../unxlngx6/bin/oosplash /home/kevin/devel/libreoffice/solver/350/unxlngx6/lib/libuno_sal.so: undefined reference to `std::__detail::_List_node_base::_M_hook(std::__detail::_List_node_base*)@GLIBCXX_3.4.15' collect2: ld returned 1 exit status dmake: Error code 1, while making '../../unxlngx6/bin/oosplash' - By executing that line manually and switching to /usr/local/bin/g++ the compile is successful.
