cmake setup:

[tkloczko@ss-desktop x86_64-redhat-linux-gnu]$ cmake -L
CMake Warning:

I tried it on OpenSUSE linux and there is no problem. Please provide full information - not only error message.

kloczek commented 2 years ago

First I've been thinking that this issue is about removed by LTO symbol but that is not the case because even with disabled LTO I have the still the same error. (BTW ENABLE_LTO option can be removed because cmake handles LTO without any problems by just changeing content of the $CFLAGS, $CXFLAGS, $LDFLAGS, $AR, $NM and $RANLIB env variables)

I'm using Fedora gcc 11.2.1. Here is extracted part from generated by rpm build script which could be used to try reproduce the issue:

CFLAGS='-O2 -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -fdata-sections -ffunction-sections'

amitdo commented 2 years ago

Are you Fedora's Tesseract package maintainer? Did you try building with Autotutools?

kloczek commented 2 years ago

No I'm not Fedora's Tesseract package maintainer.

zdenop commented 2 years ago

Seems like problem with any customization of CFLAGS/CXXFLAGS/LDFLAGS... Can you just make clean build (cmake .. && make)?

kloczek commented 2 years ago

Hmm .. what you mean "clean build". I'm using exactly the same %cmake rpm macros across all packages which are using cmake

[tkloczko@ss-desktop SPECS]$ grep -w %cmake *.spec -l | wc -l
401

Does it mean that you've been able to reporoduce reported effect using scririp which I've provided?

kloczek commented 2 years ago

Nevertheless looks like it is issue with only one lbrary public symbol. I cannot fined anything specyfic in the cose which could make that tesseract::Plumbing::AddToStack non-public :/

zdenop commented 2 years ago

With clean build I mean this:

git clone --depth=1 https://github.com/tesseract-ocr/tesseract.git
cd tesseract
mkdir build & cd build
cmake ..
make

zdenop commented 2 years ago

So classifier_tester was built and linked - the problem must be in rpm build script (outside of tesseract). I will have a look at how OpenSUSE gets info about location of ft2build.h.

kloczek commented 2 years ago

Here is the fix for pango:

Please let me know if you want those two patches as PR.

It is yet another issue. When is used BUILD_TESTS=ON you are including googletest git repo instead use system installed gtest libraries.

zdenop commented 2 years ago

Yes, please send it as 2 separate PR, so it can be checked by GH action.

Regarding your fist patch -I think it should be like this:

pkg_check_modules(Pango REQUIRED pango>=1.38.0)
pkg_check_modules(Cairo REQUIRED cairo)
- pkg_check_modules(PangoFt2 REQUIRED pangoft2)
+ pkg_check_modules(PangoFt2 REQUIRED pangoft2>=1.38.0)
 pkg_check_modules(PangoCairo REQUIRED pangocairo)

Can you test it on Fedora?

kloczek commented 2 years ago

I'm not using fedora.

This is not matter minimum version pangoft2.

More cmake issues:

man pages are not generated and installed
$(datadir}/tesseract resources are not installed

kloczek commented 2 years ago

I'm reverting my build procedure to GNU auto tools. cmake is not finished and/or broken at the moment.

However look slike GNU auto tools suffers sim,illar issues with test suit abcause it tries to compile google test submodule ainstead checking (using pkg-config) is gtest available. Buldling other projects is not good habit ..

And yet another small detail. Compile time warnings:

Just in case .. I'm not trying to critiocize yir work. What I;ve mention is more like ToDo list for 5.0.1 :)

Cheers

zdenop commented 2 years ago

Some notes for clarification:

OpenCL is not supported - search issue tracker for an explanation.
AFAIR cmake was primarily created for Windows as autotools is not available there, Nobody cares about manpages and for configs installation (I expect this is what you mean by $(datadir}/tesseract resources) I made an explanation here - I am not sure that current autotools install process is correct. Training tools are not built on windows with cmake as building e.g. pango on Windows is not easy.
cmake build is working as expected. As I already mention it works without problem on openSUSE. I also tried it now on raspberry pi ("Raspbian GNU/Linux 10 (buster)) - no problem. And cmake build is automatically tested. You can check by yourself: https://github.com/tesseract-ocr/tesseract/actions/runs/1589437109.
This is a community project. We share what we create/improve. If you want to run it on your system, you should contribute changes specific to your system. Do not expect somebody else will fix it.

it tries to compile google test submodule instead checking (using pkg-config) is gtest available

It should be possible to use an installed googletest on Linux hosts, but the current solution would still be needed for MacOS. Homebrew on MacOS has a googletest formula which conflicts with nss:

Error: Cannot install googletest because conflicting formulae are installed.
  nss: because both install `libgtest.a`

Debian has a package libgtest-dev which also installs the googletest 1.10.0 sources. Why would it be better to require an installation of those packages (which typically are not preinstalled) instead of using the existing Git submodule?

Do not waste time on compile those binaries.

If some MacOS gtest binaries have some issues it is the problem of those distributed binaries .. not the tesseract, Isn't it?

stweil commented 2 years ago

Do not waste time on compile those binaries.

time nohup make libgtest.la libgtest_main.la libgmock.la libgmock_main.la
nohup: ignoring input and appending output to 'nohup.out'

real    0m26.839s
user    0m25.440s
sys 0m1.426s

The googletest files take less than 30 seconds to compile (single threaded), and only once for a fresh build. This looks negligible compared to the total time for make check.

So how long takes to compile other libratriues used by tesseract?🤔 Why not they are included in tesseract source tree?😱

stweil commented 2 years ago

@kloczek, your comment is not helpful. Feel free to contribute a pull request which uses an existing libgtest, but still allows to use the Git submodule.

GoogleTest is not like other dependencies. It is used for unit testing which is not meant to be used bv most users.

stweil commented 2 years ago

Again your comment is not helpful. On Debian, very few packages require libgtest-dev. So most users won't have it installed.

kloczek commented 2 years ago

It is some reason why gtest provides public interface with header files and pkgconfig file as well. That reasdon is "please use that interface (only)". On debian gtest is packaged so there is no any obstacles to use system installed files.

I could understand to fall back to compile it if system gtest is not available but this is not the case here.

stweil commented 2 years ago

Is there still a build problem, or can this issue be closed?

kloczek commented 2 years ago

I don't remember. Let me check.

stweil commented 2 years ago

Yes, and the local copy works fine. In your build you just forgot to run git submodule update --init. If you want support for a pre-installed googletest, your pull request is welcome.

I close the issue as there seem to be no other problems.
