Does anybody compile protobuf successfully on HP-UX?

[Jackie]

I tried to compile protobuf many times on different HP machines with
version 2.1 and 2.2, but all failed. The failure reason is same as
below. Does anybody can gimme some advice ? Thank you in advance!

It appears that your system lacks strtoll().  You'll need to replace it somehow.  Is your system 64-bit?  If so, strtol() should work fine.  There's actually an #ifdef near the top of strutil.h which deals with this for other systems.

As for the "iter has already been declared" problem, it looks like your compiler is using very old rules regarding scope of variables declared in for() loops.  I noticed that it is also suspiciously complaining that it doesn't recognize the "-ansi_for_scope" flag, which it appears you specified yourself.  Presumably getting this flag to work would fix the problem.

Hello Kenton,

My system is 64-bit. I wrote a small sample to test strtoll(), and
surprisedly found it is not enabled by default, actually an extra
option "-ext" is needed. As for the "iter has already been declared"
problem, there is also an extra option: "-Wc,ansi_for_scope,on", but
this option can not passed into autoconf directly due to its strange
form. Lucky thing is that we can enable this option by another way: "-
AA" or "-Aa". That is exactly what I've done now. Here's my compiling
command line:
$ ./configure CXXFLAGS="-ext -AA"

Unfortunately, my good luck can not last to the end :(
Another error is reported as below, which seems to tell me that aCC's
standard header file is wrong. I'm confused.
pls kindly gimme some help. THANK YOU!

Line 477 of src/google/protobuf/compiler/command_line_interface.cc says:

    proto_path_.push_back(make_pair("", "."));

Try changing it to:

    proto_path_.push_back(make_pair(string(""), string(".")));

If this works I will commit it to SVN.

[Jackie]

Yes, it works! Thank you, Kenton :)

And I got another error report:

./ -I. --cpp_out=.
sh: ./: Execute permission denied.
*** Error exit code 126

which is located in line 2552 of src/Makefile :
2551 unittest_proto_middleman: protoc$(EXEEXT) $(protoc_inputs)
2552 ./$^ -I$(srcdir) --cpp_out=.
2553 touch unittest_proto_middleman

I noticed that there's some comments above the line:
2548 # For reference, if we didn't have to worry about VPATH (i.e.,
building from
2549 # a directory other than the package root), we could have just
written this:
2550 # ./protoc$(EXEEXT) -I$(srcdir) --cpp_out=. $(protoc_inputs)

I don't worry about VPATH, so I modified the line as below:
2551 unittest_proto_middleman: protoc$(EXEEXT) $(protoc_inputs)
2552 ./protoc$(EXEEXT) -I$(srcdir) --cpp_out=. $(protoc_inputs)
2553 touch unittest_proto_middleman

Then everything is O.K. :)

BTW, I noticed lots of warnings printed during the whole process of
compiling and linking, like this:

I guess this is caused by protobuf-2.2.0/m4/acx_pthread.m4. Maybe
you can take a look at that little problem when you're free.

And I got another error report:

       ./ -I. --cpp_out=.

*** Error exit code 126

This can also be fixed by using GNU make instead of your system's make.

 

BTW, I noticed lots of warnings printed during the whole process of
compiling and linking, like this:

It looks like acx_pthread.m4 loops through a set of flags trying to find the one that makes pthreads work.  One of the things it tries is -mthreads, which is apparently used by mingw32.  It happens that your compiler does not fail when given this flag (it only prints a warning), and then apparently pthreads work correctly by coincidence.  So the script decides to use this flag.

Since it looks like nothing is actually wrong except for some spurious warnings, I'm not going to look into fixing this myself, but feel free to send me a patch if you want.
