logger

penebang

Pustaka utilitas untuk penelusuran dan debugging kode sumber.

Dapat digunakan seperti antarmuka (hanya header) atau perpustakaan bersama.

Sistem pembangunan yang didukung

• CMembuat
• Segera AOSP

Tenggelam yang didukung

• std::cout - bawaan
• Android Logcat - jika Android (AOSP dan NDK)

Penggunaan

Kedua contoh penggunaan (hanya header atau pustaka bersama) dapat ditemukan di tes/LoggerMainTest.

Catatan perpustakaan antarmuka (hanya header).

1. Tentukan variabel berikutnya dalam kode Anda jika menggunakan std::cout sebagai keluaran logging:

 std::mutex nlab::logger::gCoutMutex; // used for output synchronization

Jika tidak, matikan cout logging melalui definisi berikutnya: LOG_OUTPUT_COUT_DISABLED , misalnya untuk CMake:

 add_definitions(-DLOG_OUTPUT_COUT_DISABLED`)

2. Untuk build CMake, atur opsi LOGGER_BUILD_HEADER_LIB=ON melalui baris perintah, misalnya:

 cmake -DCMAKE_BUILD_TYPE=Release -DLOGGER_BUILD_HEADER_LIB=ON ..

atau di file CMake teratas, misalnya:

 set(LOGGER_BUILD_HEADER_LIB ON CACHE BOOL "Build the header only library")
add_subdirectory(logger)

Contoh keluaran

Contoh keluaran yang diambil dari pengujian/LoggerMainTest

Untuk pembuatan Debug:

 cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
cd tests
make
./LoggerMainTest
