cygwin无法从/ cygdrive找到我的编译器

Question

I have a makefile which invokes my compiler from /cygdrive/c/path/to/compiler

when I'm in a cygwin shell, I can invoke it correctly, but from inside a makefile, the absolute path returns "The system cannot find the file specified" .

I don't understand why the makefile does not understand the absolute cygdrive path

edit*
In fact, any command with absolute path will fail.

/usr/bin/touch

will also return "The system cannot find the file specified" .

Answer 1

It is bad practice to use absolute paths to executables in Makefiles. You should be able to put this in the Makefile

CC=gcc

then as long as gcc.exe is on your PATH it will work. If you happen to be cross-compiling you could run this from the command line

make CC=i686-w64-mingw32-gcc
