[Error] Build Stopped: subcommand failed about jsc.js HOT 24 CLOSED

Yeah, the toolchain setup is a bit outdated. Let's see if I can find some time to fix it. Thanks for the report!

from jsc.js.

I just wanted to update. I tried some new things and it refuses to work. The error happens around [202/1094].
Here is the command causing the error : https://pastebin.com/sJZZU3pg
Here is the error I get if I manually run the command : https://pastebin.com/4Wx0YQ1x
Here is the full output including the error when running "ninja -C out" : https://paste.ubuntu.com/p/WRrFKw5TBN/ (Apparently it is too big for pastebin)

from jsc.js.

Looks like the error is caused by missing files in ./out/obj/Source/JavaScriptCore
as well as it being weird with the directory.
error: unable to open output file 'obj/Source/JavaScriptCore/inspector/JSGlobalObjectInspectorController.bc': 'no such file or directory'

from jsc.js.

hi, I just updated the build steps in README. would you mind try again? I was a bit outdated but I think it should be good now.

It says I didn't run the command when I did.

from jsc.js.

that's something changed in EMSDK. seems like emsdk no longer defines the EMSCRIPTEN environment. I've updated the prep_env.bat and you may try again.

from jsc.js.

That helps but I still run into errors :

Any suggestions on how to fix?

from jsc.js.

I'm using EMSDK from a year ago and everything seems fine. I'm not sure if this error is because of some changes in newer version emsdk. I'll find some time and try that. but before that I won't be able to know hot to fix it.
The error message itself looks very strange as how can it unable to open the output file? it complains about no such file or directory which doesn't make any sense. it is the output file and of course it doesn't exist.

from jsc.js.

What version are you using I can try downloading that in the meantime?

from jsc.js.

never mind. I just synced to the latest emsdk (1.39.16) and everything still working fine. and I'm still seeing environment "EMSCRIPTEN" being defined.

from jsc.js.

I still get the same error with the newest version. But the older versions of emscripted give me this error : "compiler frontend failed to generate LLVM bitcode"

from jsc.js.

How exactly are you installing emscripten. Could you try to redo all of the download steps?

from jsc.js.

I cloned from their repo
https://github.com/emscripten-core/emsdk.git

from jsc.js.

I think if you have trouble with emsdk, you might want to try with a wasm hello world. JSC.js is simply using emcc/emc++ just like any other wasm hello world project does. Nothing special here.

I verified that emsdk works fine with the hello world example outlined in their tutorial (https://emscripten.org/docs/getting_started/Tutorial.html#tutorial). I will try compiling jsc again.

I get a bunch of warnings as soon as I run the thing. Are you doing "emsdk install latest"? I also get an error and it stops : 1 warning and 1 error generated. em++: error: 'C:/Users/trist/Desktop/jsc/emsdk/upstream/bin\clang++.exe -target wasm32-unknown-emscripten -D__EMSCRIPTEN_major__=1 -D__EMSCRIPTEN_minor__=39 -D__EMSCRIPTEN_tiny__=16 -D_LIBCPP_ABI_VERSION=2 -Dunix -D__unix -D__unix__ -Werror=implicit-function-declaration -Xclang -nostdsysteminc -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\include\libcxx -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\lib\libcxxabi\include -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\lib\libunwind\include -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\include\compat -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\include -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\include\libc -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\lib\libc\musl\arch\emscripten -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\local\include -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\cache\wasm\include -DEMSCRIPTEN -fignore-exceptions -fno-inline-functions -MMD -MF obj/Source/JavaScriptCore/inspector/JSGlobalObjectInspectorController.bc.d -DJSCJS=1 -DENABLE_JIT=0 -DENABLE_C_LOOP=1 -DLLIntOffsetsExtractor=CLoop -DNDEBUG -DNOMINMAX -DBUILDING_JavaScriptCore -DSTATICALLY_LINKED_WITH_WTF -I../Source/JavaScriptCore/DerivedSources/JavaScriptCore -I../Source/JavaScriptCore/DerivedSources/JavaScriptCore/ForwardingHeaders -I../Source/JavaScriptCore/DerivedSources/JavaScriptCore/inspector -I../Source/JavaScriptCore/DerivedSources/JavaScriptCore/yarr -I../Source/JavaScriptCore -I../Source/JavaScriptCore/API -I../Source/JavaScriptCore/assembler -I../Source/JavaScriptCore/bindings -I../Source/JavaScriptCore/builtins -I../Source/JavaScriptCore/bytecode -I../Source/JavaScriptCore/bytecompiler -I../Source/JavaScriptCore/dfg -I../Source/JavaScriptCore/disassembler -I../Source/JavaScriptCore/domjit -I../Source/JavaScriptCore/ftl -I../Source/JavaScriptCore/heap -I../Source/JavaScriptCore/debugger -I../Source/JavaScriptCore/inspector -I../Source/JavaScriptCore/inspector/agents -I../Source/JavaScriptCore/inspector/augmentable -I../Source/JavaScriptCore/inspector/remote -I../Source/JavaScriptCore/interpreter -I../Source/JavaScriptCore/jit -I../Source/JavaScriptCore/llint -I../Source/JavaScriptCore/parser -I../Source/JavaScriptCore/profiler -I../Source/JavaScriptCore/runtime -I../Source/JavaScriptCore/tools -I../Source/JavaScriptCore/wasm -I../Source/JavaScriptCore/wasm/js -I../Source/JavaScriptCore/yarr -I../Source/WTF -I../Source/icu -fvisibility=hidden -Wno-ignored-attributes -Wno-deprecated-register -Wno-nonportable-include-path -Wno-tautological-compare -Oz -m32 -std=c++17 -fno-exceptions -fvisibility-inlines-hidden -c ../Source/JavaScriptCore/inspector/JSGlobalObjectInspectorController.cpp -Xclang -isystemC:\Users\trist\Desktop\jsc\emsdk\upstream\emscripten\system\include\SDL -c -o obj/Source/JavaScriptCore/inspector/JSGlobalObjectInspectorController.bc -mllvm -combiner-global-alias-analysis=false -mllvm -enable-emscripten-sjlj -mllvm -disable-lsr' failed (1) [343/1094] CXX obj/Source/JavaScriptCore/heap/SpaceTimeMutatorScheduler.bc In file included from ../Source/JavaScriptCore/heap/SpaceTimeMutatorScheduler.cpp:27: In file included from ../Source/JavaScriptCore/heap/SpaceTimeMutatorScheduler.h:28: In file included from ../Source/JavaScriptCore/heap/MutatorScheduler.h:29: In file included from ../Source/WTF\wtf/MonotonicTime.h:29: In file included from ../Source/WTF\wtf/Seconds.h:28: ../Source/WTF\wtf/MathExtras.h:401:43: warning: implicit conversion from 'std::__2::numeric_limits<unsigned long long>::type' (aka 'unsigned long long') to 'double' changes value from 18446744073709551615 to 18446744073709551616 [-Wimplicit-const-int-float-conversion] double fmodValue = fmod(trunc(d), std::numeric_limits<unsigned long long>::max() + 1.0); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ 1 warning generated.

And if you could update the demo so it has access to the other exported variables that would be a big help while I am trying to solve this issue

from jsc.js.

Honestly, if you tried it on another computer and could get it to work and sent me the exact steps it would probably help identify the error.

from jsc.js.

LLVM changed a bunch of default behaviors and become backward incompatible. This is annoying. Anyway I've fixed the issues and you may try again.

from jsc.js.

Whatever you did helped a lot but I get an error when linking to jsc.js
Here is the error:

from jsc.js.

interesting. I can't repro the issue. It looks like something with the compiler but I'm already using the same one as you do.
