linker-errors

I'm very new with boost spirit (and with boost). Its very interesting library. I use qtcreator + MinGW 5.3. I simply add every source file from git_hub_calc8 into new project and add some boost library, but i got the following error trying to build (All other examples work fine) C:\Program Files\boost\boost\boost\spirit\home\x3\nonterminal\rule.hpp:113: ошибка: undefined reference to `bool client::parser::parse_rule<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, boost::spirit::x3::context<boost::spirit::x3::error

I have a static library, liborc-0.4.a with no shared library. I have another library, libschroedinger-1.0.a (no shared) that depends on symbols in liborc-0.4.a. If I run nm on liborc-0.4.a, symbols such as orc_init show up as T (meaning they are defined). I built libschroedinger-1.0.a with the command line flag -lorc-0.4 so it saw the symbols and was ok. However, now I have a small executable that depends on libschroedinger-1.0.a. It compiles fine, but when I run the linker gcc -lschroedinger-1.0 -lorc-0.4 -o output input.o It gives errors such as: /usr/local/lib/libschroedinger-1.0.a

I'm trying to build a dynamic library for android wrapper around libcrypto.a as described in http://wiki.openssl.org/index.php/FIPS_Library_and_Android#Using_FIPS_OpenSSL_in_a_real_Application I've produced the libcrypto.a as suggested on the page, but when I try to compile my wrapper.c I get a linker error, multiple definition of 'atexit' Here's the command line I'm using to compile: arm-linux-androideabi-gcc wrapper.c -fPIC -shared -I/usr/local/ssl/android-14/include -Wl,-Bstatic -lcrypto -L/usr/local/ssl/android-14/lib -o libwrapper.so --sysroot=/Users/scoleman/android-ndk-r9d/platforms

I am trying to test a function with Google Test. It seems that everything is set up correctly, and it builds and executes fine without gtest... (There is a bit of complexity in the code, so I cannot list all the source files here, but without adding gtest, the files are linking properly, and running as they should). It is an application type project. It has a number of library dependencies... irrelevant. The test project is added as a separate project to the solution. It has the tested project as a dependency. The .h file of the test project only points to the gtest... The .cpp (not main,

So I'm working on linking together a Fortran and a C++ code, and I'm getting the above error when I try and run the executable. I've done some searching for other solutions, and none of the things I've found so far have helped. I'll try and include everything, but I'm not that great with this kind of stuff so if there's anything else that is needed/useful to see let me know and I'll go grab it.
