bh_read_file.h isn't in any of the include paths.

[Please-just-dont]

Now can my program link to it. The tutorial has:

#include "bh_read_file.h"

buffer = bh_read_file_to_buffer(wasm_path, &buf_size);

I cannot include "bh_read_file.h" as it's not in any of the include paths. And if I manually find where it is and include that I get an undefined reference error because it's not linking to it.

In my CMake I do as the instructions say:

include (wasm-micro-runtime-main/build-scripts/runtime_lib.cmake)
add_library(vmlib ${WAMR_RUNTIME_LIB_SOURCE})
target_link_libraries(my_target PRIVATE vmlib)

How are the include directories even added? I have access to the normal wasm headers like wasm_runtime.h, but not others.

BTW, it's in:

core/shared/utils/uncommon/bh_read_file.h

[Please-just-dont]

I've included everything:

#include "wasm_runtime.h"
#include "wasm_c_api.h"
#include "wasm.h"
#include "wasm_runtime_common.h"
#include "wasm_interp.h"
#include "wasm_memory.h"
#include "wasm_native.h"
#include "wasm_shared_memory.h"
#include "wasm.h"
#include "wasm_export.h"
#include "wasm_exec_env.h"
#include "wasm_export.h"
#include "wasm_loader_common.h"
#include "wasm_loader.h"
#include "wasm_opcode.h"

And still nothing. I also can't find:

read_wasm_binary_to_buffer

That's in the runtime initialization documentation.

The bh_read_file.h/.c is included in core/shared/utils/uncommon/shared_uncommon.cmake

[Please-just-dont]

@TianlongLiang So... I have to include that in my CMake in addition to:

include (wasm-micro-runtime-main/build-scripts/runtime_lib.cmake)
add_library(vmlib ${WAMR_RUNTIME_LIB_SOURCE})
target_link_libraries(my_target PRIVATE vmlib)

???

Yes, you can refer to iwasm CMakeLists.txt in product-mini/platforms/linux/CMakeLists.txt

include (${SHARED_DIR}/utils/uncommon/shared_uncommon.cmake)

add_executable (iwasm main.c ${UNCOMMON_SHARED_SOURCE})

@TianlongLiang Hmm, ok, well it may be a good idea if that were mentioned in the docs as someone else may have trouble. May I ask why it's done this way, including CMakeLists.txt, then you yourself defining a library and then linking to it? As supposed to doing add_subdirectory? Are there two ways to build this? Because I noticed there's a CMakeLists.txt at the root directory.

[TianlongLiang]

IIUC, what you are trying to do is embed wamr into your project, you can refer to this document and in that section give example about how to write custom CMakeLists.txt to embed wamr, it can used as reference if you want to do custom embed or something:

"Examples can be found in CMakeLists.txt of linux platform and other platforms."

You can do that too

I believe this was solved via: #4284 and can be closed.
