链接静态 c 库并使用 -fPIC 重新编译错误
Linking static c libraries and getting error recompile with -fPIC
出现很多 "undefined reference to" 错误。我的 CMakeLists.txt 中缺少什么？我没有正确链接库吗？
native-lib 应该链接到 liblept.a 和 libtesseract.a 库，我认为这些库没有链接到这些库。
这是我的 CMakeLists.txt:
cmake_minimum_required(VERSION 3.4.1)
set(distribution_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../../../../distribution)
add_library(lib_musireader STATIC IMPORTED)
set_target_properties(lib_musireader PROPERTIES IMPORTED_LOCATION

add_library(lib_tesseract STATIC IMPORTED)
set_target_properties(lib_tesseract PROPERTIES IMPORTED_LOCATION

这是我遇到的构建错误：

还有更多参考错误
您正在链接 lib_lept，但您的库名称是 liblept，因此您需要将所有出现的 lib_lept 更改为 liblept，或者更改您的库名称 liblept.a 到 lib_lept.a 随你喜欢。
这也适用于 libtesseract 和其他图书馆。
我通过使用 -fPIC 标志重新编译库解决了我的错误。
在 makefile 中像这样：
CFLAGS += -fPIC
CPPFLAGS += -fPIC
出现很多 "undefined reference to" 错误。我的 CMakeLists.txt 中缺少什么？我没有正确链接库吗？
