compiling sqlite3 ends with va_arg error

[Roman Savchenko]

Hello all,

I'm trying to compile my project dependecy sqlite3.c amalgamation, and emcc breaks on va_arg with such errors:

sqlite3.c:33735:27: error: unexpected type name 'PrintfArguments': expected expression
pArgList = va_arg(ap, PrintfArguments*);

I tried to search information at the web, but didn't find to much.

Appreciate for any help with it.

Thanks,

Roman.

Can you give the full command line you are using to compile that file?

Christian Heimes recently added an sqlite3 port to emscripten itself BTW.  You can use it by simply passing `-sUSE_SQLITE3` on the command line.

cheers,

san

I'm using the SQLChiper extension so I'm not sure that the mentioned port may help. Verbose make gives following:

/emsdk/upstream/emscripten/emcc
-DSQLITE_ENABLE_JSON1
-DSQLITE_HAS_CODEC
-DSQLITE_OMIT_LOAD_EXTENSION
-DSQLITE_TEMP_STORE=2

That seems to work fine for me. 

```

$ wget https://www.sqlite.org/2022/sqlite-amalgamation-3390000.zip

$ unzip sqlite-amalgamation-3390000.zip

$ emcc -c -DSQLITE_ENABLE_JSON1 -DSQLITE_HAS_CODEC -DSQLITE_OMIT_LOAD_EXTENSION -DSQLITE_TEMP_STORE=2 -D_GNU_SOURCE -D_SILENCE_CXX17_ITERATOR_BASE_CLASS_DEPRECATION_WARNING -fPIC -g -Qunused-arguments sqlite-amalgamation-3390000/sqlite3.c

```

I guess there could be some flag in `@CMakeFiles/.../includes_C.rsp` that is messing things up but it seems unlikely. 

cheers,

sam
