> So I checked wondered if the problem is that it is configuring for the wrong platform, so I have reviewed the code in "config", and in line 778 the OUT variable is set to "hpux-parisc1_1-$(CC)" with a comment saying that PARISC2 is no longer supported in a 32 bit build. 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.
