Hi everyone, Background:
The package rminizinc <https://github.com/acharaakshit/RMiniZinc> provides an interface to MiniZinc <https://www.minizinc.org/tutorial/minizinc-tute.pdf> in R. The package provides various functionalities to parse, solve and manipulate MiniZinc models. This is done by using the MiniZinc C++ API (libminizinc <https://github.com/MiniZinc/libminizinc>). The installation requires linking of the library an including the header files for which PKG_LIBS flag(-L/path/to/libminizinc -lmzn) , and PKG_CPPFLAGS (-I/path/to/libminizinc/include) are filled in Makevars.in which is set by configure based on the path of the library provided by the user using --configure-args or if the user doesn't provide any arguments, a default path is passed from configure (using configure.ac). Question: In one of my Rcpp functions mzn_parse() which is used to parse MiniZinc models, I sometimes need to use the files in the subdirectories of the libminizinc library. To access these files, I need to use the path of libminizinc (which can change per installation). I want to extract this path from either Makevars or configure to use it in my package. Is there any way I could retrieve this path in my scripts? Please let me know if this question is not relevant to the mailing list. The Makevars.in looks like this: CXX_STD = CXX11 PKG_CPPFLAGS = -I. @MZN_INCLUDE@ PKG_LIBS = @MZN_LIBS@ OBJECTS.tests = cpp_tests/test-runner.o cpp_tests/test-mzn_parse.o cpp_tests/test- set_params.o cpp_tests/test-mzn_eval.o cpp_tests/test-sol_parse.o cpp_tests/test- getMissingPars.o OBJECTS.sources = RcppExports.o set_params.o mzn_parse.o mzn_eval.o sol_parse.o getMissingPars.o OBJECTS.helpers = filetoString.o helper_parse.o expDetails.o pathStringcheck.o OBJECTS = $(OBJECTS.sources) $(OBJECTS.tests) $(OBJECTS.helpers) $(SOURCES:.cpp=.o) strippedLib: $(SHLIB) if test -e "/usr/bin/strip"; then /usr/bin/strip --strip-debug $(SHLIB); fi.phony: strippedLib all: clean clean: rm -f $(OBJECTS.sources) $(OBJECTS.tests) $(OBJECTS.helpers) *.so Thanks!
