If you don't like python and have problems setting up you C compiling environment, why don't use one of the numerous *other* language bindings? Ow the owshell tools?

Please understand this very simple test program first:
=== Makefile
.PHONY: all clean
CFLAGS=-I /opt/owfs/include/
LDFLAGS=-L /opt/owfs/lib64/ -lowcapi
all: owcapitest
clean:
-rm *.o owcapitest
owcapitest: owcapitest.o
$(CC) $(LDFLAGS) -o $@ $^
=== owcapitest.c
#include
#include
#include
int main(int argc, char* argv[]) {
size_t rs;
char*buf;
ssize_t rss;
if ((rss = OW_init("-s localhost:4304")) < 0) {
perror("OW_init failed");
exit(EXIT_FAILURE);
}
if ((rs = OW_get("/uncached/10.AE9C54020800/temperature", , )) <
0) {
perror("OW_get failed");
exit(EXIT_FAILURE);
}
printf("%s\n",buf);
}

Kind regards

[Owfs-developers] owcapiexample parameters to pass
Wouldsomeone Please help me with the input string needed forthe owcapiexample program. I am trying to read my 18b20 sensors that areattached to my Raspberry Pi 3 using the I2C interface. I can readthem with my browser @ “localhost:2121”. The problem is I cannot get the example code that was loaded at(/usr/share/doc/libowfs-dev/examples/owcapi/C) to work. I need helpfiguring out what parameters to pass to ./owcapiexample ??? Ihave spent countless hours at this. Please help.
