[openssl-users] Building OpenSSL 1.1.0h on HPUX 11 PARISC2 64bit

Hi,

However, I'm trying to build it in 64 bit.

You should keep in mind that it takes gcc that actually generates 64-bit
code. While it seems to be self-obvious, it was source of confusion
earlier. For example you can observe hppa2.0w-hp-hpux11.11 in gcc -v
output, yet it would generate 32-bit code [even though "w" customarily
is reference to 64 bits]. But let's say that your gcc generates 64-bit
code. Trouble is that ./config in 1.1.0 fails to detect bitness
correctly. It was corrected in master/1.1.1, but in 1.1.0 you are stuck
with manual selection as argument to ./Configure. The choice is between
hpux64-parisc2-cc and hpux64-parisc2-gcc. As for gnu assembler, it's
known limitation. I mean yes, OpenSSL PA-RISC assembly can be compiled
only with vendor assembler. So that if your gcc can't be told to use
native HP-UX assembler, then you have to configure with no-asm or
configure for hpux64-parirsc2-cc, i.e. vendor compiler.
