Building on newer Linux

[Conrad Steenberg]

Hi Tucker et al,

Trying out my first Ada-based project since 1991 (!) I'm running into some linking issues on Ubuntu 19.04. Since I do Elixir by day and used Python for many years, I'm really excited for the Parython syntax especially!

Procedure:

unzip ~/Download/parasail_release_8_0.zip

cd parasail_release_8_0/

make -j 6 all_no_gtk

Works fine, then lots of errors of the form:

/usr/bin/ld: parasail_release_8_0/lib/compiler_main.psl.o:

 relocation R_X86_64_32S against `.rodata' can not be used when

 making a PIE object; recompile with -fPIC

even though the object files are relocatable:

$ file lib/compiler_main.psl.o

 lib/compiler_main.psl.o: ELF 64-bit LSB relocatable, x86-64, 

 version 1 (SYSV), with debug_info, not stripped

Googling around it seems this might be an issue with LLVM-produced code, but wanted to ask here first to see is anybody else has any insights?

Thanks!

Conrad

To answer my own question, the solution is to change the arguments for llc in pslc.csh:

llc $llc_flags -relocation-model=pic $i.ll

The whole bootstrap procedure would probably belongs in a Makefile :)

Best,

Conrad
