Compiling gcc on HP-UX

[Vamshi-Krishna]

Hi,

I have been searching for a gcc compiler for HPUX (11.,31 ia64). The latest version which I have been able to download is 4.2.3. Is there a way for me to get a later compiler. I also tried using the following builds:

http://mirrors.develooper.com/hpux/gcc-4.7.2-11.31.sd.bz
http://mirrors.develooper.com/hpux/gcc-4.6.1-11.31.sd.bz

But both seem to be buggy, and dont work. I tried to compile gcc 4.6.1 from src using the provided gcc-4.2.3, and I get the following error on Stage-2: cc1plus out of virtual memory.

Could someone please point me to an official gcc version beyong gcc-4.2.3 ? Any help is appreciated.

You need to increase maxdsiz_64 and maxdsiz.  What are their current values?

[Vamshi-Krishna]

maxdsiz = 1073741824

maxdsiz_64 = 4294967296

That should be enough, unless you have ulimit making it smaller.

What does "ulimit -a" show?  How about "swapinfo -tam".

You seem to have enough swap and ulimit matches maxdsiz.

You might want to try that "swapinfo -tam" at the same time you get that "cc1plus out of virtual memory".

[Vamshi-Krishna]

The "swapinfo -tam" output shown above is representative of what I was observing when the issue happened.

My only other suggestion is to install tusc(1m) and then trace the process with "tusc -fp -ea -o tusc.out your-build-command".

Then look for the last few system calls done by the aborting process.

The HP-UX compiler team tells me they can provide their build of gcc 4.7.1 on request.
You could email them at hpux-compilers-java @ hpe . com .

[Vamshi-Krishna]

Unfortunately, the mail is being rejected if the size of more than 1KB (and since I have a microsoft 365 account, it will add in a lot of headers). Could someone please make the request on my behalf ? My mail seems to be 8KB in size, but my actual body is barely 3-4 lines. 

My mail id is v, a, m, s, h, i, [d o t], k, @ a, p, p, n, o, m, i, c, [d o t], c, o, m

After a brief hiatus, I am back to my original problem. I need a C++11 (atleast, C++14 if possible) compliant compiler on HPUX. I have aCC A.06.29, but it does not fully support all the C++11 features (especially atomics). I would like to build a C++11 compliant compiler (using aCC if need be). The current options are gcc-4.9.2 (for C++11) and gcc-5.2.0 (for C++14).

Could someone help me with the steps to build the gcc-5.2.0 (or if this is not possible, then gcc-4.9.2) using aCC ?
