mbuild -setup: no compiler detected

Jorge — Wed, 14 Nov 2007 15:26:47 -0500

Dear list members,

While running the command mbuild -setup allowing it to
locate installed compilers none are detected.

I am using the 64 bits Matlab R2007b version and I need to
compile some mex files. Does anyone know how to install a
new compiler and how to tell matlab that I want to use it?

The mcc compiler is installed but matlab does not put it
in the list, I have also installed a lcc-win32 compiler
which is not shown in the list.

Any ideas?

Thanks a lot in advance!

Best Regards!,
S.

64 bit Matlab R2007b does not have a compiler. Here is what
I got from Matlab Support:

" The answer to your question which you have probably
already worked out is that the MATLAB 64bit edition does
not ship with a built in LCC compiler.

Kind Regards
Clive Amos"

It would have been useful if they told me if or when they
will have a built-in compiler, or if there are alternatives.

On Windows (when I have to) I try not to use the LCC
compiler; it generates slow code. I use the freely
available Microsoft Visual C/C++ 2005 Express, for 32-bit
Windows. It generates decent code, although not quite as
good as gcc in Linux/Unix. The Professional version (which
comes at a price) is better, I think, since unless I'm
mistaken it includes additional compiler optimizations that
are disabled in the 2005 Express version.

See http://msdn2.microsoft.com/en-us/express/default.aspx

It's quite easy to configure mex to use this compiler.

However ... it appears that the Express edition doesn't
support 64-bit:

http://msdn2.microsoft.com/en-us/vstudio/aa700921.aspx

You might try gcc for windows:

http://gnumex.sourceforge.net/

that link doesn't talk about 64bit Windows, but 32bit.
However, gcc and cygwin do run on 64bit Windows.

I've got the same problem with WinXP x64. In the Matlab
compatible compiler page it is writen that 64-bit version
supports MS Visual Studio 2005 SP1 and Visual Studio
Express edition compilers. I have installed MS VS2005 with
64-bit support but still I get the message that there is no
compiler in the system. In case of Express Edition there
must be some additional windows parameter defined. But I
did not try it yet.

Dear all,

I ran into the same problem yesterday when I was trying to use the embedded Matlab function in Simulink.

Under mex -setup, there was no compiler available.

System is Windows 7 x64 (64bit) with Matlab 2009b.

After digging around I found this site:

http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/index.html?solution=1-6IJJ3L

This details how to add a 64bit compiler to your machine.

Another thing you need to make sure you do is put the files you want to compile somewhere away from Program File. So e.g. D:\Matlab, because it will not compile files with a space in the file name or folder names.

Thank u very much,
for Windows after installing MS Visual Stdio and carrying out the information in the site http://gnumex.sourceforge.net/ then typing in workspase command
>>mbuild -setup
matlab will be able to convert my m.file to exe.file
finally,Thanks list members
