matlab coder: Build error: Compilation returned error status code 2.

I want to use the MATLAB coder to transform a m file to a c file . But I always encounter the problem.

Here is the m file

function a = testfun(b,c)
a = b + c;
end

And the error report is : Build error: Compilation returned error status code 2. See the target build log in the report for further details.

Build log is : 13 link /dll /LIBPATH:"D:\SOFTWA~3\MATLAB~1\extern\lib\win64\microsoft" libmx.lib libmex.lib libmat.lib /MACHINE:X64 kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib /nologo /manifest /incremental:NO /implib:"testfun_mex.x" /MAP:".\testfun_mex.mexw64.map" /NODEFAULTLIB:LIBCMT /OUT:testfun_mex.mexw64 testfun_initialize.obj testfun_terminate.obj testfun.obj testfun_api.obj testfun_mex.obj _coder_testfun_info.obj @testfun_mex_mex.arf 14 正在创建库 testfun_mex.x 和对象 testfun_mex.exp 15 'cmd' 不是内部或外部命令，也不是可运行的程序 16 或批处理文件。 17 gmake: * [testfun_mex.mexw64] Error 1

I encounter the same problem now.did you find the possible reasons for the results and solve it in the end?

Answer 1

[Matthias]

I had the same Problem. MATLAB could not find the cmd.exe in the system path. cmd.exe is located in C:\Windows\System32

Call the command "getenv PATH" and check if the path is present. If not use for instance http://www.mathworks.com/matlabcentral/answers/94933-how-do-i-set-my-system-path-under-windows to add it.

Hope this helps Matthias

[Hari Ijjada]

i have did the same thing...i have changed the path ...but it is giving same error...what should i do ?

Answer 2

[Walter Roberson]

That software is not supported on versions of MS Windows before Windows XP.

[Hari Ijjada]

but Mine is Windows 7..but it is still giving same error ..what is the remedy for that ?

[Walter Roberson]

I would need a copy of the error message that you are getting. The original poster's error message translates as cmd being an unknown command at the MS Windows level, which is an error you get before Windows XP.

this is the report of error i got...it will be very helpfull to me if you got a answer for me ..i am spending a lot of time on this

[Walter Roberson]

Possibly you have problems with your PATH environment variable.

[Hari Ijjada]

yes...i had a problem with my PATH environment variable...i added the C/Windows/System32 to my path variable...now i am able to build the mex files..

i have resolved my issue succesfulluy...thank you so much your help

[超 陈]

i had the same problem and i added the C/Windows/System32 to my path variable.but i stll did not solve the problem ,how could i do?
