[Solved] Waf crashes on configure (--use-lld is at fault!)

Installation & Configuration Linux
#1

Running my build config, it crashes your version of waf (on git head 7fad21d5172c994fc697ea593902ecfe844d700f) or something in waf doesnt like --use-lld

CC=gcc CXX=g++ ./waf configure --prefix=/opt/ard9 --use-lld --debug-symbols --freedesktop --no-nls --no-phone-home --qm-dsp-include=/usr/include/qm-dsp

generates;

after lots of fussing around I’ve worked out that --use-lld is the cause of the problem. Removing it lets waf complete the configure

so this is more an FYI to anyone building with ‘–use-lld’

#2

I use

./waf configure --strict --ptformat --cxx17 --use-lld --backtrace --libjack=weak --compile-database --address-sanitizer

without any issues. Do you have lld installed?

#3

yep; I have llvm-23 + llvm-23 with lld. my default is

/usr/lib/llvm-23/bin/lld

I’ve been using my above config to build ardour for years, I hadnt done a build since feb (it worked back then). its odd. I tested forcing llvm-23 and llvm-23 verison of lld

LLD=/usr/lib/llvm-22/bin/lld CC=gcc CXX=g++ ./waf configure --prefix=/opt/ard9 --debug-symbols --freedesktop --no-nls --no-phone-home --qm-dsp-include=/usr/include/qm-dsp --use-lld

ok I did some more digging. this is weird and I dont know why. I moved the source tree off my NAS, and into a local disk, no errors with --use-lld.

so something doesnt like maybe the locking on an nfs build, where before I never had an issue…

so I think this is a non-issue and its just on my end. consider this resolved/closed and my bad lol.
