Mixed language C++, C and Fortran compilation with Cmake
cmake, g++, gcc, gfortran
Solution
You need to enable Fortran for the project like this:
project (q-test C CXX Fortran)
Also, you might want to use find_package(Boost) instead of hard coding an include path.
Problem
Using `g++`, `gcc` and `gfortran` on GNU/Linux, I've written a simple script to compile and link together a number of source code files written in C++, C and Fortran. Here are the complete contents of the script. This script has been tested, and works well. ``` g++ -c test-Q.cpp -I./boost/boost_1_52_0/ -g gcc -c paul2.c -g gcc -c paul2_L1.c -g gcc -c paul6.c -g gcc -c paul6_L1.c -g gcc -c fit_slope.c -g gfortran -c getqpf.F -g g++ -o test-Q test-Q.o paul2.o paul2_L1.o paul6.o paul6_L1.o fit_slope.o getqpf.o -g -lgfortran ``` To make this more cross-platform, I would like to re-write the script using Cmake. How might I handle mixed-language compilation? The following test script listed below does not work, and will only selectively compile some of the files. Is there perhaps another cross-platform build process that might be better suited for this type of compilation? ``` cmake_minimum_required (VERSION 2.6) project (q-test) include_directories(/media/RESEARCH/SAS2-version2/test-Q/boost/boost_1_52_0) add_executable( q-test test-Q.cpp paul2.c paul2_L1.c paul6.c paul6_L1.c fit_slope.c getqpf.F ) # end ```
