Ich möchte diese Software kompilieren: http://snap.stanford.edu/snap/download.html auf Ubuntu 9.10 Server.undefinierter Verweis auf `clock_gettime '. Das Hinzufügen von LIBRTDEF = -lrt zu Makefile repariert es nicht
Mein Makefile:
#
# Makefile for non-Microsoft compilers
#
## Linux (uncomment the 2 lines below for compilation on Linux)
CXXFLAGS += -std=c++98 -Wall
LDFLAGS += -lrt
LIBRTDEF=-lrt
## CygWin (uncomment the 2 lines below for compilation on CygWin)
#CXXFLAGS += -Wall
#LDFLAGS +=
all: MakeAll
opt: CXXFLAGS += -O4
opt: LDFLAGS += -O4
opt: MakeAll
MakeAll:
# $(MAKE) -C cascades
$(MAKE) -C centrality
$(MAKE) -C community
$(MAKE) -C concomp
$(MAKE) -C forestfire
$(MAKE) -C krongen
$(MAKE) -C kronfit
$(MAKE) -C mkdatasets
$(MAKE) -C motifs
$(MAKE) -C ncpplot
$(MAKE) -C netevol
$(MAKE) -C netstat
$(MAKE) -C testgraph
clean:
