Hi Rich, I've consistently been hitting issues with guestfs-tools builds. I have workarounds but they are annoying. 1) With a fresh checkout I run: $ git submodule init $ git submodule update $ autoreconf -if $ ./configure $ make -j8 I will get these errors: make[3]: Entering directory '/home/crobinso/src/guestfs-tools/builder' GEN virt-builder GEN virt-builder-repository /usr/bin/ld: virt_builder_repository-index-scan.o: relocation R_X86_64_32S against `.rodata' can not be used when making a PIE object; recompile with -fPIE /usr/bin/ld: failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit status File "caml_startup", line 1: Error: Error during linking (exit code 1) make[3]: *** [Makefile:1261: virt-builder-repository] Error 2 make[3]: *** Waiting for unfinished jobs.... /usr/bin/ld: virt_builder-index-scan.o: relocation R_X86_64_32S against `.rodata' can not be used when making a PIE object; recompile with -fPIE /usr/bin/ld: failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit status File "caml_startup", line 1: Error: Error during linking (exit code 1) make[3]: *** [Makefile:1257: virt-builder] Error 2 make[3]: Leaving directory '/home/crobinso/src/guestfs-tools/builder' I can fix it with `make -j8 CFLAGS="-fPIE -fPIC"` but only after doing a full `make clean`. 2) If I make a trivial change in common/, like adding whitespace in common/mlcustomize/customize_run.ml, subsequent guestfs-tools build will failu with: make[2]: Entering directory '/home/crobinso/src/guestfs-tools/customize' GEN virt-customize File "_none_", line 1: Error: Files customize_main.cmx and ../common/mlcustomize/mlcustomize.cmxa make inconsistent assumptions over implementation Customize_run Again, a `make clean` and rebuild will fix it. Are these expected, or is something wrong with my environment? Host is Fedora 41 Thanks, Cole
