Installation problem #78

Open rpx99 opened 2 months ago

rpx99 commented 2 months ago

Hi,

wanted to try gobo and ran the install file. Unfortunately not successful:

tron$ cc -v 
OpenBSD clang version 16.0.6
Target: amd64-unknown-openbsd7.5
Thread model: posix
InstalledDir: /usr/b

tron$ $GOBO/bin/install.sh cc

I receive lots of warnings like:

/home/rpx/Downloads/eiffel/gobo/tool/gec/bootstrap/gec1.c:102915:13: warning: left operand of comma operator has no effect [-Wunused-value]
                R = ((m1, a1, (T0*)0));
                          ^~
58 warnings generated.

And then error:

Although I never tried it on openBSD, I guess that the problem above comes from the fact that the install script does not know that cc means clang. Can clang be called directly on your machine?

$ clang -v

If so, you can try to run:

$GOBO/bin/install.sh clang

Also note that you may run into other problems because as I said above, openBSD is not part of my available platforms. GitHub Actions only provides Linux Ubuntu, MacOs and Windows.

Thanks for your swift reply and your suggestion! Looks better but does not compile fully.

Btw. I tried to copy the clang options as cc options in the bootstrap.sh file but this errors earlier as there are more switches later on.

Wonder if cc should not be equal to clang in general?

rpx99 commented 2 months ago

There seems to be even a switch in pthread:support.c


#     ifdef HAVE_PTHREAD_SETNAME_NP_WITHOUT_TID /* iOS, OS X */
        (void)pthread_setname_np(name_buf);
#     elif defined(HAVE_PTHREAD_SET_NAME_NP) /* OpenBSD */
        pthread_set_name_np(pthread_self(), name_buf);
#     else /* Linux, Solaris, etc. */
        if (EXPECT(pthread_setname_np(pthread_self(), name_buf) != 0, FALSE))
          WARN("pthread_setname_np failed\n", 0);
#     endif

So it seems HAVE_PTHREAD_SET_NAME_NP is not set?

rpx99 commented 2 months ago

For now I simply removed the code I do not need:

-#     endif
+      pthread_set_name_np(pthread_self(), name_buf);
     }

 # elif defined(GC_WIN32_THREADS) && !defined(MSWINCE)

Doing it properly would mean to define HAVE_PTHREAD_SET_NAME_NP in gec.h ?


#if defined(__clang__)

#   define GC_REQUIRE_WCSDUP
#   define HAVE_DLADDR

#       define HAVE_PTHREAD_SIGMASK

#   endif
#endif
