error: cannot convert ‘std::ifstream’ {aka ‘std::basic_ifstream<char>’} to ‘bool’ in return

Dear author:

I get error report below when I tried to install iMAAPs, and I'm sure that I had installed gsl, fftw and openmp with conda successfully.

tools.cpp: In function ‘bool file_check(const string&)’:
tools.cpp:26:9: error: cannot convert ‘std::ifstream’ {aka ‘std::basic_ifstream’} to ‘bool’ in return
return fp;
^~
tools.cpp: In function ‘bool file_open(const string&)’:
tools.cpp:35:9: error: cannot convert ‘std::ofstream’ {aka ‘std::basic_ofstream’} to ‘bool’ in return
return fp;
^~
make: *** [Makefile:19: tools.o] Error 1

Best regards
