All codes can be compiled under OSX and Linux without any warning / error. I've found the information that the error is thrown, if the main method is not found, but all programs have the main methode like int main(int argc, char* argv[]) I try to solve the problem with a full reinstall of Cygwin but it does not run. The linker command shows like: g++ -o build/test.exe -enable-stdcall-fixup examples/test.o -L/usr/local/bin -L/usr/bin -L/cygdrive/c/Windows/system32 -L/cygdrive/c/Windows -L/cygdrive/c/Windows/system32/Wbem -L/cygdrive/c/Windows/system32/WindowsPowerShell/v1.0 "-L/cygdrive/c/Program Files/TortoiseSVN/bin" "-L/cygdrive/c/Program Files/Java/jdk1.6.0_29/bin" -L/usr/bin  -L/cygdrive/c/opt/library/atlas/3.9.51/lib -L/cygdrive/c/opt/library/hdf/1.8.7/lib -L/cygdrive/c/opt/library/xml2/2.7.8/bin -L/cygdrive/c/opt/library/boost/1.47.0/bin -L/cygdrive/c/opt/library/boo st/1.47.0/lib -L/cygdrive/c/opt/library/jsoncpp/0.5.0/lib -L/cygdrive/c/opt/scons/bin -lcygboost_system -lcygboost_thread -lcygboost_iostreams -lcygboost_regex -lcygboost_program_options -lboost_exception -lcygboost_filesystem -llapack -lcblas -lf77blas -latlas -lgfortran -lhdf5_cpp -lhdf5 All depend libraries are build with Cygwin Gcc / G++ / GFortran also. I've found a lot of posting with the similar / equal problem, but no solution. Does anybody know a solution for the linker problem?
