我正在编译hadoop-yarn-nodemanager。
编译环境：#!/home/XXX/PycharmProjects/XX/venv/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==10.0.1','console_scripts','pip3'
__requires__ = 'pip==10.0.1'
import re
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
sys.exit(
load_entry_point('pip==10.0.1', 'console_scripts', 'pip3')()
)
，MacOS-10.14，java-1.7.0_80与cmake3.13.0-rc3，clang-1000.10.44.4，Maven 3.6.0。
我正在尝试在MacOS上安装protocbuf 2.5.0，但正如其文档所示，
仅* nix平台支持本机hadoop库。该库不不能与Cygwin或Mac OS X平台一起使用。
因此，我必须重新编译Hadoop的源代码。在下载的Hadoop-2.2.0文件夹中，运行hadoop-2.2.0-src，经过几分钟的编译，新的本机库应该位于mvn package -Pdist,native -DskipTests -Dtar处。但是，我一直在找回错误消息。有些已经通过修改源代码而修复，但是现在我陷入了编译hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0/lib/native的陷阱。
这是错误消息：
hadoop-yarn-server-nodemanager我试图将cmake的编译器从 [exec] [ 57%] Linking C executable target/usr/local/bin/test-container-executor
[exec] /Applications/CMake.app/Contents/bin/cmake -E cmake_link_script CMakeFiles/test-container-executor.dir/link.txt --verbose=1

切换到clang，但是没有用。
相对于错误消息，我发现以下代码。
在gcc中：
hadoop-2.2.0-src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/CMakeLists.txt在add_executable(test-container-executor
main/native/container-executor/test/test-container-executor.c
)
target_link_libraries(test-container-executor
container
)
output_directory(test-container-executor target/usr/local/bin)
中：
hadoop-2.2.0-src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/configuration.c在int launch_container_as_user(const char *user, const char *app_id,

char* const* log_dirs, const char *resources_key,
char* const* resources_values) {...}
中：
hadoop-2.2.0-src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/target/native/CMakeFiles/test-container-executor.dir/link.txt对于压缩文件/Library/Developer/CommandLineTools/usr/bin/cc -g -Wall -O2 -D_GNU_SOURCE -D_REENTRANT -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk -Wl,-search_paths_first -Wl,-headerpad_max_install_names CMakeFiles/test-container-executor.dir/main/native/container-executor/test/test-container-executor.c.o -o target/usr/local/bin/test-container-executor libcontainer.a
，我在解压缩后发现hadoop-2.2.0-src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/target/native/libcontainer.a，但是由于编码问题而无法打开它。
此外，以前在编译此项目时出现错误：
container-executor.c.o要修复此问题，我将 [exec] /Users/markdana/Downloads/hadoop-2.2.0-src/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/container-executor.c:1252:48: error: too many arguments to function call, expected 4, have 5

[exec] int mount(const char *, const char *, int, void *);
中的函数mount()的声明修改为：
mount.h这有点愚蠢，我知道，但是至少可以用。然后遇到问题中显示的新问题。我想知道他们是否担心，或者链接库存在一些错误。
已经调试了整整一天，对完成的工作一无所知。如果您可以指出密钥，或者分享一些类似的处理cmake链接问题的经验，将不胜感激。
答案 0 :(得分：1)
在OS X上似乎不存在功能fcloseall。从Porting UNIX/Linux Applications to OS X：
fcloseall此功能是
fclose的扩展。尽管OS X支持fclose，但不支持fcloseall。通过将文件指针存储在数组中并遍历数组，可以使用fclose来实现fcloseall。
您需要重新设计应用程序并存储应该用fcloseall关闭的每个文件。之后，您可以对每个此类文件使用简单的close，如引用中所述。
