Invoke the MS C++ Compiler at the run time

Invoke the MS C++ Compiler at the run time

• Steven Somer

  I tried this:

  system("CALL \"C:\\Program Files\\Microsoft Visual Studio 8\\VC\\bin\\vcvars32.bat\"");

  system("CD \"C:\\Program Files\\Microsoft Visual Studio 8\\VC\\\"");

  system("cl.exe \"c:\\main.c\"");

  and I get error:

  "This application has failed to start because mspdb80.dll was not found. Re-installing the application may fix this problem."

  Thanks,

  The first line (the vital one, the one which set up your necessary environment variables) was ineffectual. The first line opened up a new command interpreter (CMD), ran vcvars32.bat from within that interpreter, then when it completed, shut that command interpreter instance down, and it took the environment variables with it.

  Without those environment variables, it's no wonder you got errors afterward. In order for batches to work, you MUST perform one system statement only, no more no less.

  Exercise: How would you code system() such that it would execute a number of statements in just one call

  Hint: what does the first line in your posted code do

  The simple answer is to use a batch file by your own. Or you determine the needed environment variables by your won, and pass it as a separate data block to _spawnle instead of system.

  I recall someone asking a similar question last month. You can check out the discussion here:

  Yes! The compiler is just a normal console program, so you can redirect the output accordingly. The pathes and environment variables should be set correct.
