当OP写道：

readPVCData：readPVCData.o readfunc.o readlib.h
gcc -o readPVCData readPVCData.o readfunc.o readlib.h -lm -lsndfile
readPVCData.o：readPVCData.c readlib.h
gcc -c readPVCData。 c
readfunc.o：readfunc.c readlib.h
gcc -c readfunc.c

@Kevin写道：

很确定你的公关oblem是中的 readlib.h > gcc -o readPVCData readPVCData.o readfunc.o readlib.h -lm -lsndfile 。拿出来。

I'm getting the following error when I try to execute my make file:

clang: error: cannot specify -o when generating multiple output files

The issue occurred when I upgraded to Mac OSX Mavericks (Xcode 5.0.1). I have spent days trying to figure this problem out on the forums, and I'm just very lost. After deleting a previous XCode version, I reinstalled a clean one (from the Mac App Store). When I ran the following:

sudo port install gcc49

It froze trying to build libgcc-devel.

Any help as I'm desperate, working on dissertation work.

Pretty sure your problem is the readlib.h in gcc -o readPVCData readPVCData.o readfunc.o readlib.h -lm -lsndfile. Take it out.
