Bug#1010932: wasm-ld-13: unable to find library -lgcc

[Jérémy Lal]

Package: lld-13
Version: 1:13.0.1-4
Severity: normal


Hi,

I am trying to build llhttp, an indirect dependency of nodejs 16.5.0.

Using the recommended method is:

/usr/bin/clang  -v  --sysroot=/usr  -target wasm32-unknown-wasi  -Ofast  -fno-exceptions  -fvisibility=hidden  -mexec-model=reactor  -Wl,-error-limit=0  -Wl,-O3  -Wl,--lto-O3  -Wl,--strip-all  -Wl,--allow-undefined  -Wl,--export-dynamic  -Wl,--export-table  -Wl,--export=malloc  -Wl,--export=free  /home/dev/Software/debian/node-undici/js-team/deps/llhttp/src/*.c  -I/home/dev/Software/debian/node-undici/js-team/deps/llhttp/include  -o /home/dev/Software/debian/node-undici/js-team/lib/llhttp/llhttp.wasm

(I installed wasi-libc, lld, llvm, clang)
however, the result is:

 "/usr/bin/wasm-ld-13" -m wasm32 -L/usr/lib/wasm32-wasi /usr/lib/wasm32-wasi/crt1-reactor.o --entry _initialize -error-limit=0 -O3 --lto-O3 --strip-all --allow-undefined --export-dynamic --export-table --export=malloc --export=free /tmp/api-1a4e87.o /tmp/http-f5ff3b.o /tmp/llhttp-f86505.o -lc -lgcc -o /home/dev/Software/debian/node-undici/js-team/lib/llhttp/llhttp.wasm
wasm-ld-13: error: unable to find library -lgcc

I apt-installed more packages, like libunwind-dev and libc++, libclang-cpp, etc...
but it still fails.

So maybe it's a problem with llvm, after all ?
