Static link error with nettle built on Debian bookworm on arm64

[illwieckz]

When doing a linux-arm64 static build, the linkage errors out if I build the external deps on arm64 on Debian Bookworm:

build/deps/linux-arm64-default_10/lib/libnettle.a(fat-arm64.o): in function `fat_init':
Unvanquished/daemon/external_deps/build-linux-arm64-default_10/nettle/nettle-3.8.1/fat-arm64.c:219:(.text.startup+0x154):
 relocation truncated to fit: R_AARCH64_LD64_GOTPAGE_LO15 against symbol `_nettle_aes256_decrypt_c'
 defined in .text section in build/deps/linux-arm64-default_10/lib/libnettle.a(aes256-decrypt.o)
/usr/bin/ld: Unvanquished/daemon/external_deps/build-linux-arm64-default_10/nettle/nettle-3.8.1/fat-arm64.c:219:
 warning: too many GOT entries for -fpic, please recompile with -fPIC

For our release builds, we cross-compile the linux-arm64 external deps amd64 and Debian Buster, so there are multiple variations at play that may prevent us to face this problem in our release build.

When I force the -fPIC flag for the whole external deps build, the error is still there.

When I force the -fPIC flag for the whole external deps build, the error is still there.

Weird, days later I noticed it, now it worked with that flag. Well, good news then.

No, now that I cleaned-up the build folder, I get this error again…
