compile glog v0.3.5 and glags on windows from source.

Series

Guide

version

gflags

do not use offical version,instead use https://github.com/schuhschuh/gflags.git

git clone https://github.com/schuhschuh/gflags.git

cd gflags

mkdir windows-build

cd windows-build

cmake-gui ..

with options

BUILD_SHARED_LIBS ON

INSTALL_SHARED_LIBS ON

INSTALL_STATIC_LIBS OFF

CMAKE_CONFIGURATION_TYPES Release # Release

REGISTER_INSTALL_PREFIX OFF

CMAKE_INSTALL_PREFIX D:/gflags

#NAMESPACE google;gflags

NAMESPACE google

or command

	cmake -DGFLAGS_NAMESPACE=google -DCMAKE_CXX_FLAGS=-fPIC ..

we get include and lib/gflags.lib, and bin/gflags.dll

modify CMAKE/CMAKE_INSTALL_PREFIX to a non-system folder, otherwise you will need administrative privileges to run INSTALL project.

glog

Notice:

we have to new entry with BUILD_SHARED_LIB with value ON , because by default, glog is static library with extension .lib.

wget https://github.com/google/glog/archive/v0.3.5.zip

mkdir windows-build

cd windows-build

cmake-gui ..

with options

#WITH_GFLAGS ON

#gflags_DIR D:/gflags/lib/cmake/gflags

WITH_GFLAGS OFF

CMAKE_INSTALL_DIR d:/glog

CMAKE_CONFIGURATION_TYPES Release # Release

BUILD_SHARED_LIBS ON  # new by hand

generate sln and open with Visual Studio 2015 compile and install.

and we get preprocessors from glog

WIN32

_WINDOWS

NDEBUG

GLOG_NO_ABBREVIATED_SEVERITIES

GOOGLE_GLOG_IS_A_DLL=1

GOOGLE_GLOG_DLL_DECL=__declspec(dllexport)

GFLAGS_IS_A_DLL=1

CMAKE_INTDIR="Release"

LIBGLOG_EXPORTS

we get include and lib/glog.lib, and bin/glog.dll

multiple processor compile

  • windows: set_target_properties(main PROPERTIES COMPILE_FLAGS "/MP")
  • linux: make -j8

with cmake options /MD added to CMAKE_CXX_FLAGS_RELEASE

CMAKE_CXX_FLAGS_RELEASE /MD /O2 /Ob2 /DNDEBUG /MP

or

with CMakeLists.txt

if(MSVC) # WIN32

  set_target_properties(target1 PROPERTIES COMPILE_FLAGS "/MP")

  set_target_properties(target2 PROPERTIES COMPILE_FLAGS "/MP")

  set_target_properties(target3 PROPERTIES COMPILE_FLAGS "/MP")

endif()

project dependency

select ALL-BUILD and change build order by hand.

	google::SetLogDestination(google::GLOG_INFO, "../log/log_info_"); 

	LOG(INFO) << "Hello GLOG";

	return 0;

}

copy gflags.dll and glog.dll to main executable folder.

errors

error:

fatal error C1189: #error :  ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h. See the document for detail.

solution:

find_package(GFLAGS REQUIRED) # user-defined

find_package(GLOG REQUIRED) # user-defined

include_directories(${GFLAGS_INCLUDE_DIRS})

include_directories(${GLOG_INCLUDE_DIRS})

# add macro GLOG_NO_ABBREVIATED_SEVERITIES

add_definitions( -DGLOG_NO_ABBREVIATED_SEVERITIES )
