我们如何在MacOS上的CMake中设置目标上的多个RPATH目录？在Linux上,我们可以使用以冒号分隔的列表:
set_target_properties(mytarget
PROPERTIES
INSTALL_RPATH "\$ORIGIN/../lib:\$ORIGIN/../thirdparty/lib"
)
在MacOS上,我们可以在技术上添加冒号分隔列表并otool -l显示它,但不搜索这些目录:
set_target_properties(mytarget
PROPERTIES
INSTALL_RPATH "@loader_path/../lib:@loader_path/../thirdparty/lib"
)
通常情况下,如果我要在MacOS上有多个RPATH目录,我会发送多个链接器标志,这些标志将单独显示otool -l.就像是:
g++-mp-4.7 mytarget.cpp -o mytarget -Wl,-rpath,@loader_path/../lib,-rpath,@loader_path/../thirdparty/lib
这使:
Load command 15
cmd LC_RPATH
cmdsize 32
path @loader_path/../lib (offset 12)
Load command 16
cmd LC_RPATH
cmdsize 48
path @loader_path/../thirdparty/lib (offset 12)
如何使用CMake重新创建此行为？
我尝试构建gitql。
我已经安装了 go、CMake 和 MinGW，并试图让它们在 git bash 下工作，但是当我在 gitql 目录中调用 cmake 时，出现此错误：
-- Building for: NMake Makefiles
-- The C compiler identification is unknown
CMake Error at CMakeLists.txt:14 (PROJECT):
The CMAKE_C_COMPILER:
cl
is not a full path and was not found in the PATH.
To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. …在使用CMake构建文件期间出现以下错误:
CMake Warning at CMakeLists.txt:33 (FIND_PACKAGE):
By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Core", but
CMake did not find one.
Could not find a package configuration file provided by "Qt5Core" with any of the following names:
Qt5CoreConfig.cmake
qt5core-config.cmake
谁知道怎么解决这个问题？提前致谢
如何循环遍历 Jekyll 中 _data 文件夹中的每个文件？
目前，我在名为 sidebarlist.yml 的文件中有一个文件列表，如下所示：
- file1
- file2
- file3
为了循环遍历所有这些文件，我使用以下代码：
{% for sidebar in site.data.sidebarlist %}
{% for entry in site.data.sidebars[sidebar].entries %}
...
{% endfor %}
{% endfor %}
我想避免使用 sidebarlist.yml 并自动迭代 _data 中的所有文件。我可以这样做吗？
大家好我想使用以下代码捕获标签名称（72 * 30）：
$("input[type = 'radio']:checked:last").each(function() {
var idVal = $(this).attr("id");
var a = $("label[for='"+idVal+"']").text();
alert(a);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<li class="radio">
<input class="tmcp-field nav nav-pills dimension-layer-dimension tm-epo-field tmcp-radio" type="radio">
<label id="tmcp_radio_9" >72*30</label>
<span class="price tc-price hidden">
<span class="amount">20 <i class="fa fa-inr"></i></span>
</span>
</li>但代码没有alert任何意义。怎么了？
鉴于istream_iterator<int>和multimap<char, int> output.
我想所有的值复制到output的'a'关键.如何处理这个问题的最佳方法是什么？
我试过用:
transform(
istream_iterator<int>(input),
istream_iterator<int>(),
begin(output),
[](const auto value){
return make_pair('a', value);
}
)
但是我收到了错误:
错误:分配只读成员
std::pair<const char, int>::first
我想这意味着我无法写信begin(output).是我唯一的选择for_each吗？
我正在尝试使用Clion IDE编译我的游戏项目但是在移植allegro 5时遇到了问题.我收到此错误:
main.cpp:2:10: fatal error: 'allegro/allegro.h' file not found
#include <allegro/allegro.h>
我的CMakeLists是:
cmake_minimum_required(VERSION 3.5)
project(testAllegro)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
add_executable(testAllegro ${SOURCE_FILES})
INCLUDE_DIRECTORIES( /usr/local/include )
LINK_DIRECTORIES( /usr/local/lib )
file(GLOB LIBRARIES "/usr/local/Cellar/allegro/5.2.1.1_1/lib/*.dylib")
message("LIBRARIES = ${LIBRARIES}")
TARGET_LINK_LIBRARIES(testAllegro ${LIBRARIES})
我想问一下如何将外部图书馆的快板添加到Clion？
我有以下CMakeLists.txt文件来生成基于Qt的项目:
cmake_minimum_required(VERSION 2.8.12)

set(MyProjectLib_hdr ${PROJECT_SOURCE_DIR}/gui.h)

add_library(MyProjectLib SHARED

${MyProjectLib_ui_moc}
)
target_link_libraries(MyProjectLib Qt5::Widgets)
add_executable(MyProject ${MyProjectBin_src})
target_link_libraries(MyProject MyProjectLib)
当我尝试编译生成的项目时,我收到以下错误:
