问题
I am trying to use cspice with g++ for windows via mingw. Unfortunately cspice does not provide a library for mingw. The libraries are available at https://naif.jpl.nasa.gov/naif/toolkit_C.html. It gives undefined reference errors for the functions defined through cspice. It runs properly in Linux. Can anyone suggest a method to make it work.
I run:
g++ -LK:\Data\cspice\lib -IF:\CPP\Libraries\Boost\boost_1_68_0 -o foo foo.cpp -l:cspice.a -lm
The errors I get are:
undefined reference to 'furnsh_c' and other functions I use from 'SpiceUsr.h'.
Am I not linking the file properly or what is the error.
回答1:
I managed to compile this in windows using MinGW.
I downloaded the code from NASA website for UNIX not WINDOWS.
You need to download a libf2c library, the arith.h (comment this line //#include <config.h>) header and the times.h header.
Then I use the following CMakeLists.txt with MinGW and CMAKE for windows.
mkdir build
cd build
cmake .. -G "MinGW Makefiles"
mingw32-make
Some compilation errors will came out but they are very straightforward to solve.
