Hi, A few dais a go I ask something about an error that I am finding during the linkage stage of a code migrated from vc++. I also ask this in the libstdc++ list because the error was on this 'namespace'. Anyway, I have some progress but it's not enough to have yet my binary... The makefiles for this code, the libraries and the program itself, was written by me; but anything else. But I wrote wrong one library Makefile. After a revision of it, and compiling as an static library I have also a similar error, but not exactly the same. Maybe this could good to have a problem perspective to solve it. Using the gcc-4.1.2 (on a suse 10.2), the link process explotes with this: .../libISL.a(GaussianFit1D.o): In function `std::__simple_alloc<isl::Error, std::__default_alloc_template<true, 0> >::allocate(unsigned int)': /local/gcc-3.3.5/include/c++/3.3.5/bits/stl_alloc.h:232: undefined reference to `std::__default_alloc_template<true, 0>::allocate(unsigned int)' .../libISL.a(GaussianFit1D.o): In function `std::__simple_alloc<isl::Error, std::__default_alloc_template<true, 0> >::deallocate(isl::Error*, unsigned int)': /local/gcc-3.3.5/include/c++/3.3.5/bits/stl_alloc.h:242: undefined reference to `std::__default_alloc_template<true, 0>::deallocate(void*, unsigned int)' I think this is a clearer answer. All the libraries, and the program, i am trying to compile it with gcc-4.1.2, but this link process say something about a gcc-3.3.5 that is also installed on the system. >From the answer that I had from the libstdc++ list, this error could have relation with the common life between the 'libstdc++.so.6.0.8' and the 'libstdc++.so.5.0.7'. How I can fix this?! /Sergi.
