I have faced a peculiar problem today. My program gave linking error. It could not locate the strcpy or strncpy functions though I had included the string.h file. I then included the c51flp.lib file in my project. The error was removed and the hex file was generated. Then I removed the c51flp.lib file. This time on compiling, the errors didnot come. I am wondering why the errors didnot come again? Can anybody help! Mohit
Project/File Extensions, Books and Environment On the 'Environment Setup' tab, you have the choice of either 'Use settings from TOOLS.INI file' or spcific paths. Note that these settings are stored in the Project file (.uv2); however, since the Library location is usually defined by the Keil installation, I think it's better to use the TOOLS.INI file - otherwise you project may not be portable to a different Keil installation.
