There are a couple of things that either you have done wrong or I don't understand. This is how I would implement things:<br><br>core/CMakeLists.txt<br><br>SET(SRC_LIST ConfigHolder.cpp DictItem.cpp Reciter.cpp ForgetCurve.cpp Task.cpp Dict.cpp Manager.cpp WordList.cpp)<br>
ADD_LIBRARY(core ${SRC_LIST})<br><br>ui/CMakeLists.txt<br><br># You can also use CMAKE_SOURCE_DIR if FREERECITE_SOURCE_DIR is the top of your CMake tree<br>ADD_DIRECTORIES(${CMAKE_SOURCE_DIR}/core)<br><br>ADD_LIBRARY(ui Cui.cpp)<br>
# Tell CMake that ui needs to link agains core<br>TARGET_LINK_LIBRARIES(ui core)<br><br>CMakeLists.txt<br>ADD_EXECUTABLE(myprogram main.cpp)<br># myprogram depends on ui library<br>TARGET_LINK_LIBRARIES(myprogram ui)<br><br>
You don't need to use LINK_DIRECTORIES, because CMake knows where core was built and how to link it against ui.<br><br>James<br><br><div class="gmail_quote">On Tue, Dec 9, 2008 at 3:40 PM, Kermit Mei <span dir="ltr"><<a href="mailto:kermit.mei@gmail.com">kermit.mei@gmail.com</a>></span> wrote:<br>

<br>
Linux-cmd$ tree<br>
<br>
.<br>
|-- CMakeLists.txt<br>
|-- core<br>
| |-- CMakeLists.txt<br>
| |-- ... ... ...<br>
| |-- (Some source files to implement the internal function.)<br>
`-- ui<br>
|-- CMakeLists.txt<br>
|-- ... ... ...<br>
|-- (Some source files to impliment the UI)<br>
|-- main.cpp<br>
<br>
<br>
Their dependences is main.cpp -> ui -> core<br>
<br>
What's wrong with my CMakeLists.txt so that the files under the directory "ui" can't<br>
find the headers under the directory "core".<br>
<br>
1.ui/CMakeLists.txt :<br>
<br>
# Make sure the compiler can find include files from our ui library.<br>
INCLUDE_DIRECTORIES(${FREERECITE_SOURCE_DIR}/core)<br>
<br>
# Make sure the linker can find the ui library once it is built.<br>
LINK_DIRECTORIES(${FREERECITE_BINARY_DIR}/core)<br>
<br>
TARGET_LINK_LIBRARIES(Cui.o core)<br>
ADD_LIBRARY(ui Cui.cpp)<br>
<br>
<br>
<br>
2. core/CMakeLists.txt:<br>
<br>
# Set a variable $SRC_LIST to declare the source files.<br>
<br>
SET(SRC_LIST ConfigHolder.cpp DictItem.cpp Reciter.cpp ForgetCurve.cpp Task.cpp Dict.cpp Manager.cpp WordList.cpp)<br>
<br>
<br>
# Create a library called "Core" which includes the source files.<br>
# The extension is already found. Any number of sources could be listed here.<br>
<br>
ADD_LIBRARY(core ${SRC_LIST})<br>
<br>
Thanks.<br>
