参考文献：
记录下将CNStream流处理多路并发Pipeline框架适配到NVIDIA Jetson AGX Orin的过程，以及过程中遇到的问题，我的jetson盒子是用jetpack5.1.3重新刷机之后的，这是系列博客的第三篇。
这篇博客记录下编译步骤、编译过程中遇到的各种问题、问题解决步骤。中间特别简单的错误就不记录了，只记录稍微有点代表性的错误。
1 infer_server编译
先编译inferserver模块，一个模块一个模块的编译。
1.1 infer_server/CMakeLists.txt修改
cmake_minimum_required(VERSION 3.5)

set_target_properties(nvis PROPERTIES VERSION ${NVIS_VERSION})
set_target_properties(nvis PROPERTIES SOVERSION ${NVIS_VERSION_MAJOR})
然后还需要编写两个findxxx.cmake文件
1.2 FindLibCompute.cmake编写
# - Try to find Compute headers and libraries.
#
# Usage of this module as follows:
#
# find_package(LibCompute)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# LibCompute_ROOT_DIR Set this variable to the root installation of
# LibCompute if the module has problems finding
# the proper installation path.
#
# Variables defined by this module:
#
# LibCompute_FOUND System has LibCompute libs/headers
# LibCompute_LIBRARIES The LibCompute libraries
# LibCompute_INCLUDE_DIRS The location of LibCompute headers
find_path(LibCompute_ROOT_DIR
NAMES include/export_funtions.h
PATHS ${CNSTREAM_ROOT_PATH}/3rdparty/jetson/compute
)
find_path(LibCompute_INCLUDE_DIRS
NAMES export_funtions.h
PATHS ${LibCompute_ROOT_DIR}/include
)
find_path(LibCompute_CUDA_INCLUDE_DIRS
NAMES cuda_runtime.h
PATHS ${LibCompute_ROOT_DIR}/include/cuda
)
set(LibCompute_LIBRARIES "")
set(COMPUTE_LIBS cudart trteng_exp cuda_utils)
foreach(lib ${COMPUTE_LIBS})
find_library(LibCompute_LIBRARIES_${lib}
NAMES ${lib}
PATHS ${LibCompute_ROOT_DIR}/lib/linux_lib
NO_DEFAULT_PATH
)
if(LibCompute_LIBRARIES_${lib})
list(APPEND LibCompute_LIBRARIES ${LibCompute_LIBRARIES_${lib}})
endif()
endforeach()
if (LibCompute_INCLUDE_DIRS)
list(APPEND LibCompute_INCLUDE_DIRS ${LibCompute_CUDA_INCLUDE_DIRS})
endif ()
if (LibCompute_LIBRARIES)
set(LibCompute_FOUND TRUE)
endif ()1.2 findLibCVCuda.cmake编写
# - Try to find CVCuda headers and libraries.
#
# Usage of this module as follows:
#
# find_package(LibCVCuda)
#
# Variables used by this module, they can change the default behaviour and need

#
# LibCVCuda_ROOT_DIR Set this variable to the root installation of

#
# Variables defined by this module:
#
# LibCVCuda_FOUND System has LibCVCuda libs/headers
# LibCVCuda_LIBRARIES The LibCVCuda libraries
# LibCVCuda_INCLUDE_DIRS The location of LibCVCuda headers
find_path(LibCVCuda_ROOT_DIR
NAMES include/cvcuda/Version.h
PATHS ${CNSTREAM_ROOT_PATH}/3rdparty/jetson/cvcuda
)
find_path(LibCVCuda_INCLUDE_DIRS
NAMES cvcuda/Version.h
PATHS ${LibCVCuda_ROOT_DIR}/include
)
find_library(LibCVCuda_LIBRARIES
NAMES cvcuda
PATHS ${LibCVCuda_ROOT_DIR}/lib/linux_lib
)
find_library(LibNVCV_Types_LIBRARIES
NAMES nvcv_types
PATHS ${LibCVCuda_ROOT_DIR}/lib/linux_lib
)
if (LibCVCuda_LIBRARIES)
list(APPEND LibCVCuda_LIBRARIES ${LibNVCV_Types_LIBRARIES})
set(LibCVCuda_FOUND TRUE)
endif ()然后直接
cd /data/chw/nvstream/infer_server/build
cmake -DCMAKE_BUILD_TYPE=Debug ..
make -j4
然后满屏幕的报错。。。。。。。。。。。。。，

这种在标准C++库的头文件中报错的不正常，网上搜都让我加上#include <utility>，但我觉得不应该是修改标准库文件，然后我仔细看了下报错，发现有个
那我觉得应该是这个文件里面哪里写错了，
修改方法
1.4.2 no matching function for call to ‘std::unique_ptr<trt::trtnet_t>::unique_ptr(trt::trtnet_t*&, infer_server::M
/data/chw/nvstream/infer_server/src/model/model.h:114:88: error: no matching function for call to ‘std::unique_ptr<trt::trtnet_t>::unique_ptr(trt::trtnet_t*&, infer_server::Model::GetRunner(int)::<lambda(trt::trtnet_t*)>)’
114 | TEngine engine = TEngine(net, [](trt::trtnet_t* n) { trt::release_net(n); });
修改代码
//using TEngine = std::unique_ptr<trt::trtnet_t>;
using TEngine = std::unique_ptr<trt::trtnet_t, std::function<void(trt::trtnet_t*)>>;1.4.3 /usr/include/c++/11/iosfwd:193:11: error: ‘basic_ostringstream’ does not name a type; did you mean ‘basic_ostream’?
反正也是满屏幕的报错，
这个原因是因为我现在只是编译的inferser模块，但是里面的DEFER操作确实去找了外面的cnstream命令空间的东西，所以这里在infer_server的命名空间中也再定义一个DEFER
修改infer_server/include/common/utils.hpp

这是因为我编译的jetson-ffmpeg里面ffmpeg库的版本和opencv所需要的ffmpeg库版本有差异造成的，下面图中红框的是opencv需要的，但是我的jetson-ffmpeg比他低一个版本
然后我发现系统根目录的opencv是4.5，然后他用的ffmpeg版本低一个，所以直接用系统根目录下的

这是因为cmake/FindFFmpeg.cmake里面NAMES include/libavcodec/avcodec.h写成了NAMES inculde/libavcodec/avcodec.h
我这样修改之后再次编译，然后发现

根本就没有ffmepg的库呀。原因在于我的代码中，包含头文件的时候，没有加extern C,改成下面这样的
#ifdef __cplusplus
extern "C" {
#endif
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libavutil/avutil.h>
#ifdef __cplusplus
}
#endif
然后再次编译出来的库就会依赖FFmpeg了。
5.4 /data/chw/nvstream/3rdparty/freetype/lib/linux_lib/libfreetype.so.6: undefined reference to `fstat@GLIBC_2.33'
这种错误很明显就是版本问题了，我现在的工程目录下的文件是6.18的
/data/chw/nvstream/3rdparty/freetype/lib/aarch64/libfreetype.so.6.18.1
/data/chw/nvstream/3rdparty/freetype/lib/aarch64/libfreetype.so.6.14.0_backup

/data/chw/nvstream/3rdparty/freetype/lib/linux_lib/libfreetype.so.6.14.0
但是系统目录下的是6.17的
/usr/lib/aarch64-linux-gnu/libfreetype.so.6
/usr/lib/aarch64-linux-gnu/libfreetype.so.6.17.1
所以把系统路径的拷贝过来，
cp /usr/lib/aarch64-linux-gnu/libfreetype.so.6.17.1 /data/chw/nvstream/3rdparty/freetype/lib/aarch64/并且修改config脚本的内容
