PRB: #pragma comment(lib...) Can Specify Only Libraries

• The Microsoft C/C++ Compiler (CL.EXE) included with: - Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2, 5.0

SYMPTOMS

The comment pragma allows the user to insert comments into an object file or executable file. The lib specifier allows the user to pass this comment to the linker to specify additional libraries to link when using the object module. Some users utilize the lib comment pragma to add linker options as well as library names, such as:

   #pragma comment(lib, "MSVCRT -VERBOSE")

In Visual C++ 4.0, 4.1, and 4.2, the compiler correctly puts quotes around the comment string thereby causing the above code to generate the following error:

   LINK : fatal error LNK1104: cannot open file "MSVCRT -VERBOSE.lib"

RESOLUTION

Use the following new pragma to specify linker options:

   #pragma comment(linker, "<linker options>")

STATUS

This behavior is by design.

MORE INFORMATION

Sample Code

   // Compile options needed: none

   // test.c
