redefinition error with gcc 5.1

Compiling gccxml with gcc 5.1 raises the following error:

GCCXML_EXECUTABLE

Hello everyone,

I am trying to use gccxml to generate XML files but when I launc gccxml from the command line I have this error: Could not determine GCCXML_EXECUTABLE setting.

I don't know how to set this setting.

Coudl anyone tell me how to set it ?

Regards,

Alexandre.

Add Visual Studio 2015/MSVC14 support

It's been 6.5 years since the last supported Visual Studio was released. It's really hard to get a MSVC10 compiler, since it can't easily be installed on a Windows 10 machine.

This commit summarizes the places where the changes should be made to support the newer versions: d958e62

I have the MSVC 11, 12 and 14 installed on my computer, so I can help with the implementation and testing, just let me know what information is needed to make it happen.

The version numbers of the different Visual Studios are described here:
https://en.wikipedia.org/wiki/Microsoft_Visual_Studio#History

Wrong output for typedef of anonymous structs

I have the following C source typedef_anonymous_struct.c:

typedef struct {
  int car;
  int cdr;
} pair_t;

I convert it to XML by this command:

$ gccxml typedef_anonymous_struct.c -fxml=typedef_anonymous_struct.xml

In the output I expect a Struct node with no name and a Typedef node with a name. But GCCXML generates a Struct with a name:

$ echo $(xmllint --format --xpath '//Struct[@name="pair_t"]' typedef_anonymous_struct.xml)
<Struct id="_75" name="pair_t" context="_1" mangled="6pair_t" demangled="pair_t" location="f1:4" file="f1" line="4" size="64" align="32" members="_159 _160 _161 _162 _163 _164 " bases=""/>

And no Typdef at all:

$ echo $(xmllint --format --xpath '//Typedef[@name="pair_t"]' typedef_anonymous_struct.xml)
XPath set is empty

This are two bugs. The Struct must not have a name and the Typedef is missing.

Plan to support VS2012 and VS2013

Hi,
Is there a plan or a workaround we can use to make gccxml work with headers from VS2012 and VS2013 ?

Thanks！

the gccxml/GCC cmake configuration under cygwin: returns "Configuration x86_64-unknown-cygwin not supported"

after a...
mkdir bld
cd bld
cmake ..

I get...
...

I think the GNU config.guess and config.sub, configure
need to be refreshed, is there a nice ibride way to do just that with autoreconf ?

thx.

Visual C directories are not in the repo

GCC_XML looks for support directories for every compiler. Without them the GCC_XML can't support a specific compiler. These files are located in https://github.com/gccxml/gccxml/tree/master/GCC_XML/Support by default.

This repo doesn't contain the files for any of the MSVC compilers. VC9 is supported in code, but can't be used since the directory Support/Vc9 is not there.

If those files ever existed, please upload check them in to make the Visual C compilation possible again.
