Xmake in how to run and debug the target program, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Xmake is a lightweight and modern Lua-based project construction tool for cAccessPlus. Its main features are simple syntax, easy to use, more readable project maintenance, and consistent cross-platform behavior.

Run build target

Xmake also provides the run command to run the generated executable file directly for convenient and quick testing, such as:

$xmake run

Hello xmake!

Add run environment variables

We can also add environment variables that set the default running target program through the add_runenvs interface in xmake.lua.

Therefore, for PATH, it is very convenient to add values through this interface, and this interface supports multi-value settings, so it is usually used to set multi-valued env with path sep.

Target ("test")

Set_kind ("binary")

Add_files ("src/*.c")

Add_runenvs ("PATH", "/ tmp/bin", "xxx/bin")

Add_runenvs ("LD_LIBRARY_PATH", "/ tmp/lib", "xxx/lib")

For more information on this interface, see the documentation: add_runenvs interface documentation.

Custom running logic

If the simple environment settings and the default loading and running rules do not meet the requirements, we can implement more complex running logic by customizing the on_run script:

For example, run the installed apk program:

Target ("test")

-.

-- set custom run scripts, automatically run installed app programs, and automatically obtain device output information

On_run (function (target))

Os.run ("adb shell am start-n com.demo/com.demo.DemoTest")

Os.run ("adb logcat")

End)

Debugger command line debugging

We can also pass the-d parameter, call debugger programs such as gdb/lldb, and load the object file for debugging:

$xmake run-d

Xmake will use the system's own debugger to load the program to run, currently supports: lldb, gdb, windbg, vsjitdebugger, ollydbg and other debuggers.

[lldb] $target create "build/hello"

Current executable set to 'build/hello' (x86' 64).

[lldb] $b main

Breakpoint 1: where = hello`main, address = 0x0000000100000f50

[lldb] $r

Process 7509 launched:'/ private/tmp/hello/build/hello' (x86 / 64)

Process 7509 stopped

* thread # 1: tid = 0x435a2, 0x0000000100000f50 Hello`main, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1

Frame # 0: 0x0000000100000f50 Hello`main

Hello`main:

-> 0x100000f50: pushq% rbp

0x100000f51: movq% rsp,% rbp

0x100000f54: leaq 0x2b (% rip),% rdi; "hello world!"

0x100000f5b: callq 0x100000f64; symbol stub for: puts

[lldb] $

Using vscode for breakpoint debugging

We can also use the xmake-vscode plug-in in conjunction with vscode to implement breakpoint debugging support for the cmax cymbal + project.

In addition, we also need to rely on vscode's C++ plug-in for debugging support, but this plug-in is almost necessary due to the development of the cUnix censor + program, so it's not a big problem.

Even if the plug-in is not installed, xmake-vscode will load system debuggers such as lldb/gdb/vsjitdebugger to load and debug directly.
