I think you mean “.C” (with a capital C) which I’ve seen used occasionally for 
C++, though not in a long time.
Since the Mac filesystem is case-insensitive (though case-preserving), I 
believe the logic that maps extensions to languages ignores case, so treats 
“.C” like “.c”.

Re: [sqlite] Problem building amalgamation

[Keith Medcalf]

g++ assumes that all source input files are c++

sqlite3.c is C source, not C++

Compile the C files using gcc using the -c option (to output .o files)
Compile the C++ files using gcc or g++ using the -c option (to output .o files)
Link the files using g++ so that the c++ runtime is included
 OR link using gcc and manually add the -lstdc++ runtime library

Alternatively you can use gcc for the compile & link all-in-one step and 
manually add the library -lstdc++

But most compilers can cope with both in the same project.  Just make sure that 
your compiler compiles files with ".c" extension as C and not C++.

This problem is especially bad on Apple devices, since many people use ".c" as 
an extension for C++ files, when Apple’s compiler assumes they’ll use ".cpp".

SQLite is not C++ but C.

[sqlite] Problem building amalgamation

[Jeff Archer]

SQLite 3.13.0

I have just grabbed the sqlite3.c and sqlite3.h from another (working)
project and dropped then into a new project and I am seeing compile errors.

New project is a C++ project in Eclipse.  using GCC 5.4.0 from cygwin64.
Just trying to make a simple command line app.

I'm sure I'm missing something simple but nothing is clicking...


g++ -std=c++11 -fpermissive -P -dD -o HelloCPP.exe HelloCPP.cpp sqlite3.c


Errors...

sqlite3.c:25153:48: error: cannot convert 'SrcList::SrcList_item*' to
'SrcList_item*' in initialization
 struct SrcList_item *pItem = >a[k];
^
sqlite3.c:25156:18: error: invalid use of incomplete type 'struct
SrcList_item'
 if( pItem->zDatabase ){
  ^

sqlite3.c:25157:49: error: invalid use of incomplete type 'struct
SrcList_item'
   sqlite3StrAccumAppendAll(pAccum, pItem->zDatabase);
