Hi, if I in Keil uVision IDE (3.31) use GNUARM compiler, IDE makes program without errors, but if I use WINARM compiler, IDE shows this errors. Where is problem, please? Build target 'release' compiling main.c... arm-elf-gcc: @.\obj\main.__i: No such file or directory arm-elf-gcc: no input files linking... arm-elf-gcc: @.\obj\Test1.lnp: No such file or directory arm-elf-gcc: no input files Target not created
