C++ libicuuc.so.52，需要libboost_regex-mt.so 介绍

我想编译一段使用ICU和libboost的代码。为此，我使用以下

install.sh

文件。问题是我遇到了以下错误：

/usr/bin/ld: warning: libicuuc.so.52, needed by /opt/boost-1.54.0/lib/libboost_regex.so, not found (try using -rpath or -rpath-link)

我知道我必须在cmakeLists.txt文件中添加一些内容：

set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS} -rpath=/opt/icu_52.1/")

但它不起作用：

c++: error: unrecognized command line option ‘-rpath=/opt/icu_52.1/’

当我尝试时：

set（CMAKE\u CXX\u FLAGS“-std=c++11${CMAKE\u CXX\u FLAGS}-Wl，-rpath=/opt/icu\u 52.1/”

错误：/usr/bin/ld:warning:libicuuc.so.52，未找到/opt/boost-1.54.0/lib/libboost_regex-mt.so所需的文件（请尝试使用-rpath或-rpath链接）

---

Install.sh

---

CmakeLists.txt

---

添加到CMakeLists.txt文件：

link_directories(/opt/icu_52.1/lib)

---

您还可以尝试查看是否有人为ICU编写了查找包，无论如何，它不属于标准的cmake模块。

@Antonio我确信我必须在那里添加一些内容。但是我忘记了正确的命令：

set（CMAKE\u CXX\u FLAGS）-std=c++11${CMAKE\u CXX\u FLAGS}-Wl，-rpath=/opt/icu\u 52.1/”

（注意附加的

-Wl，

），在cmake中，您可以通过使用命令

link\u directories

添加目录来做到这一点：

libicuuc.so.52似乎不在您的
Boost\u LIBRARY\u DIRS`路径中。首先，查找您是否有
libicuuc.so.52
，以及它在/opt/icu\u 52.1/lib中的位置。因此，我必须添加/opt/icu_52.1/lib@Antonios与-Wl，-rpath=/opt/icu_52.1/“？@HaniGoc相同。最好不要将添加正确标志的工作留给cmake。不应将
rpath
标志与cmake命令混合使用。
