Thank you for your quick response. The problem is that all of the errors appear to be in the RC_helper.cpp/RC_helper.h (whichever I try) file provided with the program. So it appears that the syntax within the library file that came with the program is incorrect... Have others used the RC_helper.cpp/RC_helper.h file successfully? I also tried compiling the unedited RC_example2.cpp and I got: Error RC_example2.cpp: .\RC_helper.h: 9 syntax error; found `CharArray' expecting `;' Error RC_example2.cpp: .\RC_helper.h: 9 syntax error; found `{' expecting `;' Error RC_example2.cpp: .\RC_helper.h: 9 skipping `{' Error RC_example2.cpp: .\RC_helper.h: 10 syntax error; found `:' expecting `;' Error RC_example2.cpp: .\RC_helper.h: 10 skipping `:' Error RC_example2.cpp: .\RC_helper.h: 11 redeclaration of `CharArray' previously declared at .\RC_helper.h 9 Error RC_example2.cpp: .\RC_helper.h: 11 syntax error; found `:' expecting `;' Error RC_example2.cpp: .\RC_helper.h: 11 skipping `:' Error RC_example2.cpp: .\RC_helper.h: 11 syntax error; found `1024' expecting `)' Error RC_example2.cpp: .\RC_helper.h: 11 skipping `1024' Error RC_example2.cpp: .\RC_helper.h: 12 undeclared identifier `m_buff' Error RC_example2.cpp: .\RC_helper.h: 12 type error in argument 1 to `malloc'; found `pointer to int function(void)' expected `unsigned int' Error RC_example2.cpp: .\RC_helper.h: 12 operands of = have illegal types `int' and `pointer to char' Error RC_example2.cpp: .\RC_helper.h: 13 undeclared identifier `m_size' Error RC_example2.cpp: .\RC_helper.h: 13 operands of = have illegal types `int' and `pointer to int function(void)' Error RC_example2.cpp: .\RC_helper.h: 13 type error: pointer expected Warning RC_example2.cpp: .\RC_helper.h: 14 missing return value Error RC_example2.cpp: .\RC_helper.h: 15 unrecognized declaration Error RC_example2.cpp: .\RC_helper.h: 15 undeclared identifier `m_buff' Error RC_example2.cpp: .\RC_helper.h: 15 type error in argument 1 to `free'; found `int' expected `pointer to void' Warning RC_example2.cpp: .\RC_helper.h: 15 possible usage of m_buff before definition Warning RC_example2.cpp: .\RC_helper.h: 15 missing return value Error RC_example2.cpp: .\RC_helper.h: 16 undeclared identifier `m_size' Warning RC_example2.cpp: .\RC_helper.h: 16 possible usage of m_size before definition Error RC_example2.cpp: .\RC_helper.h: 18 too many errors

Hello, I am currently working on a project that requires MATLAB to communicate with Geochemist's Workbench. I found the sample code provided within the documentation and tried compiling it as a MATLAB MEX file only to receive many errors such as: lcc preprocessor error: pipe.cpp:4 Could not find include file <iostream> lcc preprocessor error: pipe.cpp:5 Could not find include file <string> Error pipe.cpp: .\RC_helper.cpp: 26 syntax error; found `stdiopipe' expecting `;' Error pipe.cpp: .\RC_helper.cpp: 26 syntax error; found `(' expecting `)' Error pipe.cpp: .\RC_helper.cpp: 26 skipping `(' "unnamedpipe" Error pipe.cpp: .\RC_helper.cpp: 26 extraneous old-style parameter list Error pipe.cpp: .\RC_helper.cpp: 26 syntax error; found `)' expecting `;' Error pipe.cpp: .\RC_helper.cpp: 26 skipping `)' Error pipe.cpp: .\RC_helper.cpp: 30 syntax error; found `&' expecting `)' Error pipe.cpp: .\RC_helper.cpp: 30 skipping `&' `pipe' Error pipe.cpp: .\RC_helper.cpp: 32 undeclared identifier `pipe' Error pipe.cpp: .\RC_helper.cpp: 32 left operand of . has incompatible type `int' Error pipe.cpp: .\RC_helper.cpp: 32 type error: pointer expected Warning pipe.cpp: .\RC_helper.cpp: 32 possible usage of pipe before definition Error pipe.cpp: .\RC_helper.cpp: 36 redefinition of `Clear' previously defined at .\RC_helper.cpp 30 Error pipe.cpp: .\RC_helper.cpp: 36 redeclaration of `Clear' previously declared at .\RC_helper.cpp 30 Error pipe.cpp: .\RC_helper.cpp: 37 too many arguments to `Clear' Error pipe.cpp: .\RC_helper.cpp: 38 asm: label _Clear: redefined Error pipe.cpp: .\RC_helper.cpp: 43 syntax error; found `&' expecting `)' Error pipe.cpp: .\RC_helper.cpp: 43 skipping `&' `pipe' Error pipe.cpp: .\RC_helper.cpp: 45 undeclared identifier `DWORD' Warning pipe.cpp: .\RC_helper.cpp: 45 Statement has no effect Error pipe.cpp: .\RC_helper.cpp: 45 too many errors I was wondering if you know if it's something I'm doing wrong or if the provided code itself does not function. If so, who do you suggest I contact to aid in the process of writing a pipe between MATLAB and GWB? Thank you.
