Integrate sw for arm build #97

Closed Ottunger closed 2 years ago

Ottunger commented 2 years ago

Hello,

I'm trying to build a project using Tesseract and OpenCV for android. The windows build works perfectly fine, and I'd like to use the NDK toolchain to build natively for android (and then add a JNI calling class, but that's out of this scope).

I don't find a way to tell sw to use the toolchain of the NDK. I've placed all executables of the toolchain in my PATH, and I had to modify SWConfig.cmake to read:

set(sw_platform_args
        ${storage_dir}
        ${stsh}
        -platform arm64
        ${mt_flag}
        -compiler clang-12.0
        ${os}
        -d "${wdir}"
    )

because I couldn't find another way to pass arm64.

Anyways, now I'm stuck with:

Exception in file D:/dev/cppan2/client2/src/sw/driver/module.cpp:120, function operator (): error in module (C:/Users/Ottunger/.sw/storage/tmp/cfg/116146/loc.sw.self.a55044-0.0.29.dll): Exception in file D:/dev/cppan2/client2/src/sw/driver/target/native.cpp:772, function findCompiler: Librarian not found

And looking at this repo, this means the "lib" is not found in the settings, so can you tell me how to reference the lib?

I don't mind to temporarily modify SWConfig.cmake to already prove the feasibility end to end, and then make it cleaner if OK.

egorpugin commented 2 years ago

Hi,

Do you have small example or repro? So I could test it myself.

It seems, cmake thing is easy to fix.

As for lib (or Librarian) you can try to add -DSW_DEBUG=1 or what variable it is in SWConfig.cmake, so it will print sw command. Next, run that command with --trace flag and attach output here.

Ottunger commented 2 years ago

Looks like the built command is: C:/Windows/System32/sw.exe -static -platform arm64 -compiler clang-12.0 -linker ld -d C:/Users/Ottunger/Desktop/dev/satoris-ocr/cmake-build-release-ndk-23/.sw/cmake -config r integrate -cmake-deps C:/Users/Ottunger/Desktop/dev/satoris-ocr/cmake-build-release-ndk-23/.sw/cmake/sw.txt -cmake-file-version 6

Anyways, you can find the repo that I'm trying to build here: https://gitlab.satoris.lu/satoris/satoris-ocr .

Let me know if anything!

egorpugin commented 2 years ago

I see. Try to install lld package (or take lld linker from llvm). I hardcoded this some time ago because of poor ld performance on big projects.

egorpugin commented 2 years ago

Also it's better to use non-master (release) version of tess. https://gitlab.satoris.lu/satoris/satoris-ocr/-/blob/master/CMakeLists.txt#L15 I did not update master branch for some time, but there is v5.2.0. https://software-network.org/org.sw.demo.google.tesseract.libtesseract

Ottunger commented 2 years ago

Okay, let me have a look. NDK provides ld.exe and ld.lld.exe should I force the command to contain these?

egorpugin commented 2 years ago

NDK provides ld.exe and ld.lld.exe should I force the command to contain these?

I don't think it will catch it from cmd.

Ottunger commented 2 years ago

Hmmm used tesseract 5.2.0, that's ok.

For the android build though, still can't get it OK.

If I leave x64 as platform I get the following:

If I force platform arm64

CMake Error at C:/Users/Ottunger/.sw/storage/etc/sw/static/SWConfig.cmake:235 (message):

So, could you tell me how I can force which ld to use, even by modifying SWConfig.cmake? Supposing this error means ld is not found of course!

egorpugin commented 2 years ago

The problem is that packages do not support android. I did not do any testing for it, because of lack of time. To try to add android support I need small repro. I'll take your example.

Ottunger commented 2 years ago

Sure, that seems fair! Let me know if I can help or test anything.

Must say, this project is already great job so far :)

egorpugin commented 2 years ago

How do you run that cmake? From Android studio?

Ottunger commented 2 years ago

From CLion, by using a "system" toolchain, and referencing clang binaries. I added -DCMAKE_TOOLCHAIN_FILE -DANDROID_ABI -DANDROID_PLATFORM

From Android studio, I couldn't get SW to find clang binary, although it is in my PATH. Says "Cannot find compiler org.LLVM.clang"

egorpugin commented 2 years ago

So, I tried android build with sw itself.

Create sw.cpp

void build(Solution &s)
{
    auto &ocr = s.addStaticLibrary("ocr");
    ocr += cpp17;
    ocr +=
        "opencv_hough_lines.cpp",
        "process.cpp",
        "TD1Builder.cpp",
        "ocr.cpp"
        ;
    ocr += "org.sw.demo.intel.opencv.imgcodecs"_dep;
}

Create sw toolchain file for android win2android.json, fix your sdk paths:

{
    "name": "win2android",
    "native": {
        "program": {
            "asm": "org.LLVM.clang",
            "c":
            {
                "package": "org.LLVM.clang",
                "command":
                {
                    "do_not_add_target_argument": "1",
                    "program": "d:/dev/android/sdk/ndk/25.0.8775105/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android30-clang.cmd"
                }
            },
            "cpp":
            {
                "package": "org.LLVM.clangpp",
                "command":
                {
                    "do_not_add_target_argument": "1",
                    "program": "d:/dev/android/sdk/ndk/25.0.8775105/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android30-clang++.cmd"
                }
            },
            "lib": "org.LLVM.ar",
            "link":
            {
                "package": "org.LLVM.clang",
                "command":
                {
                    "do_not_add_target_argument": "1",
                    "program": "d:/dev/android/sdk/ndk/25.0.8775105/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android30-clang++.cmd"
                }
            }
        },
        "stdlib": {
            "c": null,
            "compiler": null,
            "kernel": null,
            "cpp": null
        }
    },
    "os": {
        "kernel": "org.torvalds.linux",
        "version": "5.17"
    }
}

Run

sw build -settings-file win2android.json

Now sw says that it must complete platform checks (like cmake does):

Performing 9 check(s): org.sw.demo.jpeg-9.5.0 (jpeg), config 772283
[5/9] Check WORDS_BIGENDIAN requires to be set up manually
[8/9] Check HAVE_SIZEOF_UNSIGNED_CHAR requires to be set up manually
[9/9] Check HAVE_SIZEOF_UNSIGNED_SHORT requires to be set up manually
Waiting for completing cc checks.
Run 'D:/dev/swst/etc/sw/checks/772283/cc/run.sh' and press and key to continue...

What does it mean? Libraries do such checks on configure stage. For example, check pointer size on this platform, size of some types. To do this, sw needs to run small check binaries on target (!) platform. So you need to run android arm64 emulator or real device, write some script to transfer check files there, run checks command and return files back. You need to add following flags to sw -wait-for-cc-checks -cc-checks-command win2android_aarch64_checks.bat. To run android emulator use tools/emulator.exe. To copy files and run commands use platform-tools/adb push/shell/etc.

For some reason arm64 emulator does not start for me, so you are kindly encouraged to do this and provide feedback.

Hmmm thanks for the tests so far.

So, trying to understand because as much as I understand the basic concepts of creating a C/C++ program or library, I'm all new to SW. I added the file sw.cpp, but doesn't it need any headers?

Anyways, I could fix the paths and run your command to build. After having manually for now ran the checks and imported the results, I re-ran the command and I got:

C:\Users\Ottunger\Desktop\dev\satoris-ocr>sw build --settings-file win2android.json
Performing 43 check(s): org.sw.demo.tiff-4.4.0 (tiff), config 313738
Exception in file D:/dev/cppan2/client2/src/sw/driver/module.cpp:120, function operator (): error in module (C:/Users/Ottunger/.sw/storage/tmp/cfg/116146/loc.sw.self.e0ea5f-0.0.29.dll): Exception in file C:/Users/Ottunger/.sw/storag
e/pkg/b2/ef/b415/src/sdir/sw.cpp:115, function build: no type: 0, 0

Code at that position is 

else if (!tiff.DryRun)
        throw SW_RUNTIME_ERROR("no type: " + tiff.Variables["SIZEOF_SIGNED_INT"].toString() + ", " + tiff.Variables["SIZEOF_SIGNED_LONG"].toString());

making me think all configure checks have not been registered? Can I check this?

egorpugin commented 2 years ago

Try to remove c:\users\u\.sw\storage\etc\sw\checks (copy to checks1 dir to not lost them). Re-run command with --print-checks and post log here.

sw build --settings-file win2android.json --print-checks

Your error definitely means that SIZEOF_SIGNED_INT was not determined.

I added the file sw.cpp, but doesn't it need any headers?

Sw will downloaded needed headers.

Not sure if the zeroes are expected.

egorpugin commented 2 years ago

is the "os" the target config or the compiler config

In json file this is target config.

Not sure if the zeroes are expected.

Size of int, of course, cannot be zero.

If I change in the json to os.arch = aarch64 and os.kernel = com.Microsoft.Windows.NT

If you change it in config, it will use MSVC compiler probably and that tiff error 0 0 shows that I also did not test arm64 windows build yet. Compiler is available, but i do not have win arm64 host to run checks again.

Ottunger commented 2 years ago

Not sure what I should test now to be honest?

Maybe it would work if I force the results of the checks manually, but I'd like to know why they return zeroes. Any idea?

egorpugin commented 2 years ago

It is cached for some reason already. Just remove checks dir. To set checks manually add parameter -wait-for-cc-checks. It will point to some dir. Open it, you will see text file. Open it, replace ? with actuabl values. Press enter in sw window.

Ottunger commented 2 years ago

The thing is, even when I remove checks dir and I add --wait-for-cc-checks, the process does not stop, it goes all the way to the fault. Tried removing .sw folder in the folder where I do the command, but no luck there either.

    instead of

    bin/aarch64-linux-android21-..."
egorpugin commented 2 years ago

Also try to use updated binary. sw.client.sw-1.0.0.exe.zip

Ottunger commented 2 years ago

Oooook, so:

my mistake for aarch64, that said it didn't change anything. Using the updated client yields much better results, and compilation starts!

However, I think the libs are not well made available (see opencv error), and the standard lib behaves weirdly?

Can you send me checks dir, so I also try actual building?

checks.zip

This is what I have!

Btw, you don't have <string> include in TD1Builder.h.

checks.zip

Can you re-run sw with --print-checks because at the moment I cannot determine what check dir is for. One can be host check and other for android.

Ottunger commented 2 years ago

Hmmm really strange that I now need <string> where a build for x86_64 works without anything? Is there an addes stdlib by default there?

Anyways, the complete command gives

Guess that will need modifications in the library here though :( Can I see the path that made me import this lib? Strange to me to have poly1305 with OpenCV and Tesseract.

  2. sw build -settings-file win2android.json -sfc --print-checks -wait-for-cc-checks -static -sd

With it I see only linker error in the last command. But adding -static hides some errors which is not right.

You can go to .sw/rsp. Remove all filex except the newest two. Remove from .rsp file -pthread arg and you'll see:

One unresolved from tess (have to adjust it build script) and one from opencv.

Okay, you're better off than me, I'm surprised about my error then but I will try your command already.

Unfortunately, I don't have much clue in how SW chooses what to give to linker as input, to know why these two are not made available...

egorpugin commented 2 years ago

Those are just build script errors. I prepared them for main platforms at first. Again because of limited time. Android/IOS was not tested.

Ottunger commented 2 years ago

I bet, is normal to have priorities :)

Didn't manage to achieve same result with your command, I get an error of another undefined type still at compile time personally.

egorpugin commented 2 years ago

Seems I missed this change for you. Add arch in config.

    "os": {
        "kernel": "org.torvalds.linux",
        "version": "5.17",
        "arch": "aarch64"
    }
egorpugin commented 2 years ago

So I am able now to build this shared library. Add -llog after you see this error.

Ottunger commented 2 years ago

I managed to build the static lib libocr-0.0.1.a

Now should I try without the -static flag? This .bat file you run to finish the process, where do you get it from?

Also, does your build system set any variable to preprocessor? So that I can keep "ddlspec" in case of a CMake build?

Subsidiary question, how can I copy checks X to checks Y? Each time I modify the build command I must replay all the checks... I would like to say to go see for results of checks of the previous run.

egorpugin commented 2 years ago

This .bat file you run to finish the process, where do you get it from?

In .sw/rsp dir.

Also, does your build system set any variable to preprocessor? So that I can keep "ddlspec" in case of a CMake build?

You can try to left your code unchanged. I do not remember, maybe it was just a warning. If no, just add #ifndef OCR_API ... #endif.

Subsidiary question, how can I copy checks X to checks Y?

Copy checks.txt from prepared dir to new one which it asks for.

Ottunger commented 2 years ago

Cool thanks for the hints.

How did you build the .so? If I just take out the flag -static I end up with error:

Check out this post https://github.com/SoftwareNetwork/sw/issues/97#issuecomment-1194445529= and go to p.3.

Ottunger commented 2 years ago

Well this command works for me, but it generates the static lib, .a, and not the shared lib, .so. Hence I say, I tried to take out the -static, but no luck

egorpugin commented 2 years ago

Remove all files from rsp dir. Also re-check your sw.cpp, maybe you did not update it. Re-run.

Ottunger commented 2 years ago

That's my sw.cpp

void build(Solution &s)
{
    auto &ocr = s.addStaticLibrary("ocr");
    ocr += cpp17;
    ocr += "OCR_API"_api;
    ocr +=
            "opencv_hough_lines.cpp",
            "process.cpp",
            "TD1Builder.cpp",
            "ocr.cpp"
            ;
    ocr += "org.sw.demo.intel.opencv.imgcodecs"_dep;
    ocr += "org.sw.demo.intel.opencv.videoio"_dep;
    ocr += "org.sw.demo.intel.opencv.video"_dep;
    ocr += "org.sw.demo.google.tesseract.libtesseract"_dep;
}

And cleaning rsp does not help.

Just to be clear, to build the .so, you used command with or without -static?

egorpugin commented 2 years ago

Without.

That's my sw.cpp

You still have outdated sw.cpp. I provide it full expecting you to copy it full, not adding lines. You do not see changes in line auto &ocr = s.addStaticLibrary("ocr"); (your outdated line, check mine).

Upd.: Actual line should be

auto &ocr = s.addSharedLibrary("ocr");

or even

auto &ocr = s.addLibrary("ocr");
egorpugin commented 2 years ago

I see. Probably you need

auto &ocr = s.addSharedLibrary("ocr");

and run command WITH -static.

Sorry for misleading.

Ottunger commented 2 years ago

Ah, I'm bad at copying because I try to understand x)

So, with your last comment I still get:

But let me try a clean build too

egorpugin commented 2 years ago

So, with your last comment I still get: (https://github.com/SoftwareNetwork/sw/issues/97#issuecomment-1194558085)

It is ok, it is current progress. Now go post https://github.com/SoftwareNetwork/sw/issues/97#issuecomment-1194445529 and go to p.3.

Ottunger commented 2 years ago

Okay gotcha now! I have the .so library too :)

Will be time for some testing in place, but for this, I need a JNI declaration! This is supposedly the role of OcrServiceJNI.cpp:

#include <jni.h>
#include "ocr.h"

extern "C"
JNIEXPORT jstring JNICALL
Java_lu_satoris_android_ocr_OcrService_ocr(JNIEnv *env, jobject, int video, int psmType=6) {
    char* result = ocr("data", false, nullptr, video, psmType, false);
    if(!result) return nullptr;
    return env->NewStringUTF(result);
}

But I guess I should use also some custom declaration here?
