Hello Volker (& others with interest) I get the same error in Sage 6.7, but this time adding the recommended include directive to the Cython file doesn't work. Error message below, but I note that a workaround (however temporary) is to modify the offending file, si_gmp.h, so that
# include <cf_gmp.h> reads instead as # include <../factory/cf_gmp.h> In this case it compiles & links just fine. john perry Here's that error as I encounter it now: RuntimeError: Error compiling ./dynamic_algorithm.pyx: running build running build_ext building '_Users_cantanima_common_Research_SAGE_programs_gb_detection_dynamic_algorithm_pyx_1' extension gcc -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -I/Applications/sage-6.7-untouched/local/include/singular -I/Applications/sage-6.7-untouched/local/include/csage -I/Applications/sage-6.7-untouched/local/include -I/Applications/sage-6.7-untouched/local/include/python2.7 -I/Applications/sage-6.7-untouched/local/lib/python/site-packages/numpy/core/include -I/Applications/sage-6.7-untouched/src/sage/ext -I/Applications/sage-6.7-untouched/src -I/Applications/sage-6.7-untouched/src/sage/gsl -I. -I/Applications/sage-6.7-untouched/local/include/python2.7 -c _Users_cantanima_common_Research_SAGE_programs_gb_detection_dynamic_algorithm_pyx_1.cpp -o build/temp.macosx-10.9-x86_64-2.7/_Users_cantanima_common_Research_SAGE_programs_gb_detection_dynamic_algorithm_pyx_1.o -w -O2 In file included from /Applications/sage-6.7-untouched/local/include/singular/structs.h:15:0, from /Applications/sage-6.7-untouched/local/include/libsingular.h:6, from _Users_cantanima_common_Research_SAGE_programs_gb_detection_dynamic_algorithm_pyx_1.cpp:257: /Applications/sage-6.7-untouched/local/include/singular/si_gmp.h:5:22: fatal error: cf_gmp.h: No such file or directory # include <cf_gmp.h> ^ compilation terminated. error: command 'gcc' failed with exit status 1 -- You received this message because you are subscribed to the Google Groups "sage-support" group.
