Unknown file type: cjpeg.bc

[jens-duttke]

Hello,

I'm getting the following error when I try to compile the project (with emscripten 3.1.51):

wasm-ld: error: unknown file type: cjpeg.bc
wasm-ld: error: unable to find library -ljpeg
emcc: error: '/home/jens/emsdk/upstream/bin/wasm-ld -o cjpeg.wasm cjpeg.bc -L/deps/mozjpeg/.libs -ljpeg -L/home/jens/emsdk/upstream/emscripten/cache/sysroot/lib/wasm32-emscripten -lGL -lal -lhtml5 -lstubs-debug -lnoexit -lc-debug -ldlmalloc -lcompiler_rt -lc++-noexcept -lc++abi-debug-noexcept -lsockets -mllvm -combiner-global-alias-analysis=false -mllvm -enable-emscripten-sjlj -mllvm -disable-lsr /tmp/tmp7utesnwqlibemscripten_js_symbols.so --strip-debug --export-if-defined=main --export-if-defined=__start_em_asm --export-if-defined=__stop_em_asm --export-if-defined=__start_em_lib_deps --export-if-defined=__stop_em_lib_deps --export-if-defined=__start_em_js --export-if-defined=__stop_em_js --export-if-defined=__main_argc_argv --export-if-defined=fflush --export=emscripten_stack_get_end --export=emscripten_stack_get_free --export=emscripten_stack_get_base --export=emscripten_stack_get_current --export=emscripten_stack_init --export=stackSave --export=stackRestore --export=stackAlloc --export=__errno_location --export=__get_temp_ret --export=__set_temp_ret --export=__wasm_call_ctors --export-table -z stack-size=65536 --initial-memory=16777216 --max-memory=2147483648 --no-entry --stack-first --table-base=1' failed (returned 1)

in the following step:

emcc -03 cjpeg.bc -s LEGACY_VM_SUPPORT=1 -s "EXPORTED_RUNTIME_METHODS=[]" -s ELIMINATE_DUPLICATE_FUNCTIONS=1 -s ALLOW_MEMORY_GROWTH=1 --memory-init-file 0 --pre-js ../../../cjpeg_pre.js --post-js ../../../cjpeg_post.js -L"$DIR/deps/mozjpeg/.libs" -ljpeg -o cjpeg.js

The file cjpeg.bc is there, so it's not because of a missing file.

Do you have any ideas what could be wrong here?

I'm trying to compile it, because I want to use jpegtran -drop, which requires to specify a second image, which seems not to be considered yet.

Thanks!
