The options -GR (Visual C++ and Intel for Windows) and The options -EHsc (Visual C++ and Intel for Windows) and -Ae (Digital Mars) tell the compiler to enable C++ exception handling. This makes the compiler’s output easier to read. The options -nologo (Visual C++ and Intel for Windows) and -q (Borland) tell the compiler not to print its name and version to theĬonsole. Options don’t apply to any particular file instead they enable or disable Most of the command-line options in Tableġ-7 fall into the fourth category: general configuration information. For more information on -I option, see Recipe 1.5. Installation I specified this directory in Table 1-7 using the notation /stlport/stlport. stlport/stlport subdirectory of the Digital Mars Option, where to search for the STLPort headers. Library, the compiler must be told, using the -I Since the STLPort library is not Digital Mars’s built-in standard That falls into the third category, locations to search for files, appears in the command Necessary to specify the extension of an executable.
Most toolsets use -o to specify an output executable, but In thisĬase, however, the way the file name is passed to the compiler depends on the toolset. Hello, depending on the operating system. There is also a single output file, hello.exe or Where you place the name of the input file, as long as it doesn’t appear in the middle ofġ-7, I placed hello.cpp at the very end of Single input file, hello.cpp, and it is passed to theĬompiler simply by writing the name of the file on the command line. In general, the information passed to the compiler Remember that you only need to be concerned with the rowĬorresponding to your toolset. Now let’s look at the command lines in Table 1-7. As another example, the toolsets Visual C++ and Digital Mars both contain tools Version of vcvars32.bat before using the command-line Have multiple versions of Visual C++ installed, you must make sure to run the correct Name, causing the wrong tool to be invoked during the build process. Is not always a good idea, however, since several toolsets may contain tools with the same Changing your environment variables permanently To run the script each time you start a command-line session how this is done, depends on It’sĪlso possible to make the environment variable settings permanent so that you don’t have The command-line tools, as I demonstrated for Visual C++ and Intel 9.0 for Linux. One way to use such a script is to run it from the command line before invoking any of Record the locations of headers and libraries and other information.

It’s, therefore, commonįor Windows toolsets to provide scripts that set a number of environment variables to Headers and their compiled runtime support libraries, for example. However, there have traditionally been a number of competing C++ compilers two differentĬompilers will almost certainly have to look in different locations to find their standard The environment variables it requires are set by default to correct values. On Windows, theĭirectories in PATH are also searched when a dynamicĬommand-line tools make use of environment variables on both Unix and Windows, but on Unix there is typically a dominant C++ compiler and
