C/C++ 跨平台(android/unix/windows)工具库(xlog日志)，支持log打印、检测内存泄露_Linux

简介

这是一个通用c工具库，支持 unix(android)/windows 等平台

组件

log
- logger : logger门面. xlog 和 slog 实现它定义的宏
- xlog : 支持打印 level/tag/tid/time 这些log头和日志信息
- slog : 简易log实现，实际上是对printf的二次包装, 只支持打印level/tag和日志信息
thread
data
file
memory
- string : asprintf, stringbuilder, str_params, strlcpy, strlcat, strreplace, strsplit, strtrim, strutf8len …
- allocator : 跟踪和检测heap内存，帮助你提早发现内存泄露和踩内存等问题.
- mplite : 内存池实现 sqlite’s memsys5 memory subsystem
ring_buffer
time

编译

常用平台 (windows/linux/android)

platform	onekey deploy build	manual build
windows	`deploy_for_windows.bat release`	`make_windows.bat win32 release 1`
linux	`chmod +x *.sh && ./deploy_for_linux.sh release`	`chmod +x *.sh && ./make_cross_platform.sh linux m64 release`
android	`deploy_for_android.bat release c++_static`	`make_android.bat armeabi-v7a release`

其他平台 (交叉编译)

首先，在 tool/cmake/toolchains 文件夹下写cmake交叉编译规则文件:

set(unix true cache bool "")
set(cmake_system_name linux) # this one is important
set(cmake_system_version 1)  # this one not so much
# tell the cmake script what the platform name is, must setup this for cross compile
set(platform hisi)           # important: tell script the platform name

set(cross_toolchain_dir "/root/toolchains/hisi-linux/x86-arm/arm-himix100-linux")
set(cross_toolchain_path_prefix "${cross_toolchain_dir}/bin/arm-himix100-linux-")
message(status "current cross_toolchain_path_prefix is => ${cross_toolchain_path_prefix}")

#set compiler location
set(cmake_c_compiler "${cross_toolchain_path_prefix}gcc")
set(cmake_cxx_compiler "${cross_toolchain_path_prefix}g++")
set(cmake_ar "${cross_toolchain_path_prefix}ar")
set(cmake_linker "${cross_toolchain_path_prefix}ld")
set(cmake_ranlib "${cross_toolchain_path_prefix}ranlib")
set(cmake_strip "${cross_toolchain_path_prefix}strip")

set(cmake_find_root_path  ${cross_toolchain_dir})
# sysroot.
set(cmake_sysroot "${cross_toolchain_dir}/sysroot")
# search for programs in the build host directories
set(cmake_find_root_path_mode_program never)
# for libraries and headers in the target directories
set(cmake_find_root_path_mode_library only)
set(cmake_find_root_path_mode_include only)

set(platform_common_flags " -fpic")
string(append cmake_c_flags          "${platform_common_flags}")
string(append cmake_cxx_flags        "${platform_common_flags}")
string(append cmake_exe_linker_flags "${platform_common_flags} -fpie")
add_definitions(-d_lcu_not_support_pthread_setname) # custom compile definitions

执行 cmake 命令编译:

./make_cross_platform.sh hisi release

cmake -h. -b./build_abcd -dbuild_static_libs=on -dbuild_shared_libs=off -dbuild_demo=off -dcmake_try_compile_target_type=static_library -dcmake_toolchain_file=./cmake/toolchains/abcd.toolchain.cmake
cmake --build ./build_abcd --config release --target lcu_static
