how to include file.

i write a hello world program. and add head file.

i just want to test my eclipse+mingw enviroment.

using namespace std;

int main() {
cout return 0;

but , i can not compile.
`Standard_OStream' has not been declared

**** Internal Builder is used for build ****
g++ -ID:\OCC632\win32\ros\inc -O0 -g3 -Wall -c -fmessage-length=0 -osrc\test2.o ..\src\test2.cpp

D:/OCC632/win32/ros/inc/Standard_values.h:35:2: #error "check config.h file or compilation options: either HAVE_LIMITS or HAVE_LIMITS_H should be defined"

my path of head files ist D:\OCC632\win32\ros\inc
is it right?

i can not compile , why?

Paul Jimenez's picture

OpenCASCADE will not compile out of the box with MinGW. Files need to be modified and libraries/DLLs rebuilt. You may get past that error by adding HAVE_LIMITS to the list of defined preprocessing macros in Eclipse (I have no idea where that option may be), or, as a quick check adding




That is not a solution, though.
