[Live-devel] Compile issue with 2004.02.09 code

[Clark N. Taylor]

I found the same problem when compiling on Solaris.  This is what I did 
to fix it.

The "<<" function is defined in 
BasicUsageEnvironment/BasicUsageEnvironment.cpp.  This is the only thing 
that points to cerr.

I changed those functions to the following (don't remember what it was 
before...):

UsageEnvironment& BasicUsageEnvironment::operator<<(char const* str) {
  fprintf (stderr,"%s",str);
    return *this;
}

UsageEnvironment& BasicUsageEnvironment::operator<<(int i) {
  fprintf (stderr,"%d",i);
    return *this;
}

UsageEnvironment& BasicUsageEnvironment::operator<<(unsigned u) {
  fprintf(stderr,"%d",u);
    return *this;
}

UsageEnvironment& BasicUsageEnvironment::operator<<(double d) {
  fprintf(stderr,"%f",d);
    return *this;
}

UsageEnvironment& BasicUsageEnvironment::operator<<(void* p) {
  fprintf(stderr,"%x",p);
    return *this;
}
