如何强制 make/GCC 显示命令? [英] How do I force make/GCC to show me the commands?

问题描述

我正在尝试调试编译问题，但我似乎无法让 GCC(或者可能是 make??)向我显示它正在执行的实际编译器和链接器命令.

I'm trying to debug a compilation problem, but I cannot seem to get GCC (or maybe it is make??) to show me the actual compiler and linker commands it is executing.

这是我看到的输出:

  CCLD   libvirt_parthelper
libvirt_parthelper-parthelper.o: In function `main':
/root/qemu-build/libvirt-0.9.0/src/storage/parthelper.c:102: undefined reference to `ped_device_get'
/root/qemu-build/libvirt-0.9.0/src/storage/parthelper.c:116: undefined reference to `ped_disk_new'
/root/qemu-build/libvirt-0.9.0/src/storage/parthelper.c:122: undefined reference to `ped_disk_next_partition'
/root/qemu-build/libvirt-0.9.0/src/storage/parthelper.c:172: undefined reference to `ped_disk_next_partition'
/root/qemu-build/libvirt-0.9.0/src/storage/parthelper.c:172: undefined reference to `ped_disk_next_partition'
collect2: ld returned 1 exit status
make[3]: *** [libvirt_parthelper] Error 1

我想看到的应该是类似这样的:

What I want to see should be similar to this:

$ make
gcc -Wall   -c -o main.o main.c
gcc -Wall   -c -o hello_fn.o hello_fn.c
gcc   main.o hello_fn.o   -o main

请注意此示例如何显示完整的 gcc 命令.上面的例子仅仅展示了CCLD libvirt_parthelper"之类的东西.我不确定如何控制这种行为.

Notice how this example has the complete gcc command displayed. The above example merely shows things like "CCLD libvirt_parthelper". I'm not sure how to control this behavior.

推荐答案

调用试运行:

make -n

这将显示 make 正在尝试做什么.

This will show what make is attempting to do.
