Hi!
I'm trying to compile em-Dosbox (but it happens the same with any other transcompile I try after updating emscripten).

Hi, I'm trying to prepare a Docker image with Emscripten (based on Ubuntu 15.10) and it works fine except image size what is huge. Major chunk of image is consumed by clang. There is an output.

Question is: Can we do something with compilation flags that in default it will produce size optimized clang binary files?

There is no 1.36.8 release here so it fails. Can this be fixed? I want to try downgrading from 1.36.9 to 1.36.8 to see emscripten-core/emscripten#4506 gets fixed or not.

$ fastcomp/fastcomp/bin/clang -v
clang version 6.0.1 (/b/s/w/ir/cache/git/chromium.googlesource.com-external-github.com-emscripten--core-emscripten--fastcomp--clang 98df4be387dde3e3918fa5bbb5fc43e1a0e1daac) (/b/s/w/ir/cache/git/chromium.googlesource.com-external-github.com-emscripten--core-emscripten--fastcomp 1b4148f39a69c7fc62edadd85e4122b68694dfb7) (emscripten 1.38.31 : 1.38.31)

Presumably because we haven't kept emscripten-version.txt up to date.
Do we even need that version? Upstream clang doesn't report it at all.

Hi just trying to compile this project.

Currently I am using the following commands:

cd ./HiGHS/src
em++ ./interfaces/highs_c_api.cpp -I . -s WASM=1 -o sol.js -std=c++11

There are a number of errors shown in the full log below.

The main error is "undeclared identifier" for many of the ia32 '__builtin_ia32_readeflags_u32', '__builtin_ia32_writeeflags_u32', '__builtin_ia32_rdpmc', ...

Do I need to set a flag? Is this expected?

shared:ERROR: compiler frontend failed to generate LLVM bitcode, halting

After I build the source of emscripten 1.37.0, I find that emcc do not recognise __declspec. In 1.35.0, It is just a warning, but now it is an error and treat __declspec as a class. The example code and error message is :
class __declspec(dllexport) A
{
};
error : unknown type name '__declspec'

Is it because the new version emscripten do not support this or I need to modify some kinds of configure ?
