Hi,

I tried to compile with aCC on HP-UX, but it couldn't work out. Anyways
, it is not very important to get libcURL compiled with aCC (C++
Compiler specifically).

I also tried to configure/compile libcURL with GCC, it works but with
some changes I made.
-----
1. It seems that autoconf script (configure) is broken for HP-UX 11.00 .
   -- Removed Check for function "select" function in it, and forced it
to think that select is well present, so it doesn't exit abnormally
without creating Makefiles. 2. Again autoconf is broken , so I changed
manually the setting in lib/config.h . I have attached the working file.
   It is as per _my_ configuration

So, on a whole it doesn't seems to be libcURL problem.
If somebody needs to compile for 7.10.3 on HP-UX he can do the same :-)

Regards,
Rohit

I think your HP-UX version is also a factor here. Seems to be 11.00...

Right, but the absense of that header should not be reason for a compile
failure and I don't think it is here either.

No, it checks if the include file is usable and it checks for the
presense of a select function, it does not check if the function itself
is usable.

The check for the presense of select() fails due to the compiler being
very strict about things, as the config.log shows:

(This is the first error out of two when checking for the select
function.)

configure:14734: checking for select
configure:14784: aCC -Ae -o conftest -g conftest.c >&5
Error 42: "configure", line 14809 # ANSI C requires same function
declarations to have compatible types. Previous function declaration was
"int select(int,fd_set *,fd_set *,fd_set *,timeval *)"
["/usr/include/sys/time.h", line 489].
    char select ();
         ^^^^^^

This is the culprit of your problem. Is it possible to somehow lax the
strictness of the compiler when you run the configure script?
