在Windows上使用cmake编译gstreamer应用程序
在Windows上使用cmake编译gstreamer应用程序
提问于 2015-12-16 17:59:39
我正在尝试使用windows下的gstreamer库，使用cmake。
下面是我的简单测试代码：
#include <gst/gst.h>
int main (void)
{
gst_init (NULL, NULL);
return 0;
}我从这里得到了库("gstreamer-1.0-devel-x86-1.6.1.msi")：http://gstreamer.freedesktop.org/data/pkg/windows/1.6.1/
并尝试使用以下CMakeList.txt编译程序：
cmake_minimum_required(VERSION 2.8.12)
project(test_g)
SET(CMAKE_CXX_WARNING_LEVEL 4)
if (MSVC)
add_definitions("/W4")
else()
add_definitions("-Wall -Wextra")
endif ()
include(CheckCXXCompilerFlag)
CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)
CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X)
if(COMPILER_SUPPORTS_CXX11)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
elseif(COMPILER_SUPPORTS_CXX0X)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")
else()
message(STATUS "The compiler ${CMAKE_CXX_COMPILER} has no C++11 support. Please use a different C++ compiler.")
endif()
file(
GLOB_RECURSE
source_files
./*
)
file(
GLOB_RECURSE
gst_files
${CMAKE_CURRENT_SOURCE_DIR}/deps/lib/*.a
${CMAKE_CURRENT_SOURCE_DIR}/deps/lib/*.lib
)
add_executable(
test_g
${source_files}
)
set(GSTREAMER_INCLUDE_DIRS "./deps/include/gstreamer-1.0" "./deps/include/glib-2.0" "./deps/lib/glib-2.0/include" "./deps/lib/gstreamer-1.0/include")
if (WIN32)
set(GSTREAMER_LIBRARIES ${gst_files})
else()
message(FATAL_ERROR "Gstreamer not found")
endif()
include_directories(${GSTREAMER_INCLUDE_DIRS})
target_link_libraries (test_g ${GSTREAMER_LIBRARIES})我想避免使用pkgconfig，因为我的目标是使编译变得容易。
不幸的是，这是行不通的：

... Many other errors ...我的问题如下：
- 我应该同时使用.lib和.a文件吗？
- 为什么它不编译？文件libglib-2.0.dll.a位于lib目录中，所以我不确定在链接过程中问题是什么.
谢谢!

好吧，我找到问题所在了。我只需要接受*dll.a文件，所以现在的代码是：
file(
GLOB_RECURSE
gst_files
${CMAKE_CURRENT_SOURCE_DIR}/deps/lib/*dll.a
)我想我们可以用适当的方法来做，所以如果有人有更好的主意，我会感兴趣的。
