Here's an example:
use Inline CPP => 'DATA'
greet();
__DATA__
__CPP__
#ifdef __INLINE_CPP_STANDARD_HEADERS
#include <string>
#else
#include <string.h>
#endif
#ifdef __INLINE_CPP_NAMESPACE_STD
using namespace std;
#endif
void greet() {
string mygreeting = "Hello world!\n";
cout << mygreeting;
}
// End of CPP
(First line of that example is missing the ';' at the end, btw.)
You probably should work that into a test script - as it's not working with
either of my MS compilers (though the 0.33_003 test suite is passing all
tests). No problems with my mingw g++ compiler.
Let's just concentrate on my 32-bit MSVC++ 7.0 compiler. It's a fairly
regular sort of compiler (that doesn't need to link to any weird libraries),
and I have a perl-5.10.0 that was built using it.
Having built and installed Inline-CPP-0.33_003 it defines both
__INLINE_CPP_STANDARD_HEADERS and __INLINE_CPP_NAMESPACE_STD to 1.
But here's what I get when I try to build the above demo:

Stop.
A problem was encountered while attempting to compile and install your
Inline
CPP code. The command that failed was:
nmake > out.make 2>&1
The build directory was:
C:\_64\pscrpt\inline\_Inline\build\davido_pl_c4daa
To debug the problem, cd to the build directory, and inspect the output
files.

#########################################
If I rebuild Inline-CPP-0.33_003 specifying 'cl -TP /EHsc' as the compiler
(instead of the default 'cl -TP'), then the test suite still passes, and all
that noise about "unwind semantics" being unavailable is removed, but the
exact same linking errors remain when I try to build the demo.
Anyone able to glean anything useful from those error messages ?
I think that most of the recent MS compilers will suffer the same fate.
There has been no such problem with the earlier releases of Inline::CPP
(from before David took it on), but that's probably just that nothing was
being done that made this problem apparent
I also get essentially the same with that other "troublesome" x64 MS
compiler, but it's probably simpler to just concentrate on this MSVC++ 7.0
compiler - having to deal with that bufferoverflowU.lib requirement would
just be an added complication at this stage.
In any case, I think it likely that the same fix will apply to both
compilers (and probably many other MS compilers as well).
Cheers,
Rob
