Re: Compiling under cygwin

[Dr . Jürgen Sauermann]

    Hi Bill,
      
      strange. According to the config log that you kindly provided:
      
    #define HAVE_AFFINITY_NP 1
    
    which means that according to the confgurere.ac of GNU APL lines 291
    ff.
    the following test program compiled successfully:
    
    
    #include <pthread.h>
    #include <ext/atomicity.h>
    
    int
    main()
    {                     
      cpu_set_t cpuset;]
      pthread_setaffinity_np(0, sizeof(cpuset), &cpuset);]
      pthread_getaffinity_np(0, sizeof(cpuset), &cpuset);]
     _Atomic_word count = 0;]
      __gnu_cxx::__exchange_and_add_dispatch(&count, 1);]
    __gnu_cxx::__atomic_add_dispatch(&count, 1);]
    }
    
    
    But then this fails:
    
    memory_benchmark.cc: In function ‘void multi(int, int, int64_t*)’:
    memory_benchmark.cc:147:9: error: ‘CPU_ZERO’ was not declared in
    this scope
      147 |         CPU_ZERO(&cpus);
          |         ^~~~~~~~
    memory_benchmark.cc:148:9: error: ‘CPU_SET’ was not declared in this
    scope
      148 |         CPU_SET(c, &cpus);
          |         ^~~~~~~
    memory_benchmark.cc:149:9: error: ‘pthread_setaffinity_np’ was not
    declared in this scope
      149 |         pthread_setaffinity_np(ctx[c].thread,
    sizeof(cpu_set_t), &cpus);
          |         ^~~~~~~~~~~~~~~~~~~~~~
    ...
    
    I believe that you may need to troubleshoot this a bit deeper on
    your machine (where are
    pthread_setaffinity_np() and CPU_ZERO/CPU_SET defined (supposedly
    under /usr/local)?
    
    In the meantime you could delete the following lines in
    tools/Makefile.am:
    
    noinst_PROGRAMS += memory_benchmark
    memory_benchmark_SOURCES = memory_benchmark.cc
    memory_benchmark_LDADD = -lpthread
    memory_benchmark_CXXFLAGS = -Wall
    
    and then autoreconf and ./configure again at  the top-level.
    
    In the meantime I will look into removing the memory_benchmark
    from the standard build.
    
    Best Regards,
    Jürgen
