Building libffi for emscripten

tobi-laa commented 11 years ago

I was attempting to build the patched version of libffi with emscripten but was unsuccessful. I am really not sure whether I used the right commands, though. Here is what I did:

autoconf
emconfigure ./configure --host=i386-pc-linux-gnu --prefix=${EMSCRIPTEN_SYSTEM_ROOT} --enable-static=yes --disable-shared --disable-libtool
emmake make

Which yielded the following error:

make[3]: Entering directory `/home/tobi/Desktop/emscripten-libffi-emscripten_fix/i386-pc-linux-gnu'
depbase=`echo src/prep_cif.lo | sed 's|[^/]*$|.deps/&|;s|\.lo$||'`;\

make[1]: Leaving directory `/home/tobi/Desktop/emscripten-libffi-emscripten_fix/i386-pc-linux-gnu'

Any input on what went wrong would be highly appreciated ;-)

Good question. The thing we do not do is call autoconf. Perhaps scrape it and try without.

Thanks for replying. Without calling autoconf, the option --disable-libtool is not recognized by configure Continuing to build then gives me this error:

Also having this problem. What did you do about the assembly files for the emscripten build?

racerxdl commented 10 years ago

Same problem here. Also I didnt found any LLVM Assembly codes o.O
