Uncaught ReferenceError: __setjmp is not defined ??

[Steffen Köhler]

Hi

When compiling with

emcc -o luac.js luac.o print.o liblua.a

wrap it with
emcc -o luac.html luac.o print.o liblua.a

and run it in Chrome 39,

it comes up with

Uncaught ReferenceError: __setjmp is not defined

which is true, at least I can find only the call in the generated code, but not a declaration of __setjmp().

What I'm doing wrong?

Many thanks in advance & a happy new year :-)

Steffen

Update:

In the meantime I discovered that the Ubuntu package still contained an older emscripten version, so I removed and manually installed the latest SDK (1.28). Also I removed all optimizations from my Makefile and made sure that really the fastcomp compiler is used, but nevertheless I get a compilation warning

emcc -O0 -Wall -DLUA_USE_POSIX  -o luac.js  luac.o print.o liblua.a

warning: unresolved symbol: _longjmp

warning: unresolved symbol: _setjmp

and a crash when try to test it in nodejs

nodejs luac.js dummy.luamissing function: _setjmp

The program I try to compile is just a command line tool, it's the well known Lua (5.1), but not the interpreter, it's the compiler (luac) instead. I've also seen the Lua example and wonder why the interpreter is working smoothly while the compiler fails, as they both probably have a very similar if not even the same build progress. ?!?

Any idea is highly appreciated :-)

best regards

Steffen

Fastcomp should reduce setjmp to emscripten_setjmp, and so forth. What shows up in the console when you build with EMCC_DEBUG=1 in the env? (It should say if fastcomp is being used, etc.).

Did you try just using setjmp rather than _setjmp?

Hello Bruce

I've to admit that I've no clue where in the sources this command is used and how to change it.. - I'm  just a poor "end user" who wants to transfer the lua compiler functionality into a online web page to allow easy script generation for an embedded system. But how the lua compiler works by itself, I've no idea.... :-|

[Steffen Köhler]

Hi Bruce,
after thinking twice about it: Do you mean I should change the call in the generated js? I'll give it a trial next :-)

You can find it and change it in the C that you're compiling.

Hello Bruce

originally I was worry if I'm able to find and fix in the sources, but finally I've made it :-)

The compilation is working now- many thanks for your support!

best regards

Steffen

[Bruce Mitchener]

I looked into this a bit when I got home and before sleeping...

The actual big that should be addressed is in emscripten. I will file a bug report or submit a pull request that fixes it.

I am glad that you have a workaround for now. :)
