CMEM_init();CMEM_alloc();CMEM_free()

我git了aml_hardware_decode_demo/ionplayer.c
做了交叉编译工具链，但是始终找不到下面这三个函数引用了哪个头文件
CMEM_init();CMEM_alloc();CMEM_free()

请告知。

2

从引用方式可以看出来，在系统路径下：/usr/include

make的日志如下：-Wimplicit-function-declaration警告的几个函数找到了头文件，但是CMEM_init();CMEM_alloc();CMEM_free()还是没有找到头文件。

@youngor 不要交叉编译，直接在板子上编译就好。

5

在板子上用cmake编译也会找不到cmem，请问有什么方法解决吗，我想把它放进一个c++的程序中

Hi @qintian

你用的什么固件？怎么编译的？参考demo编译也不行？

7

参考demo的编译是可以通过的，gcc -o ionplayer ionplayer.c -lamcodec -lamadec -lamvdec -lamavutils -lpthread
但是我在使用cmake时出现了找不到cmem库的问题

cmake中引入了这些库：
# target_link_libraries(ionplayer PRIVATE spdlog::spdlog amcodec amadec amavutils ${AVCODEC_LIBRARY} ${AVFORMAT_LIBRARY} ${AVUTIL_LIBRARY} ${AVDEVICE_LIBRARY})
