libmetis-gtsam issue #380

linzha0 · 2020-07-08T02:00:10Z

Hi, I am in Ubuntu 20.04 and built gtsam follow the quick start and build the github branch successfully with a install path.

Then I try to build the OdometryExample.cpp with cmake(with ROS but plain gtsam). The CMakeLists.txt is shown below. The build was successfully, too.

cmake_minimum_required(VERSION 3.0.2)
project(sidescan_slam)

## Compile as C++11, supported in ROS Kinetic and newer
add_compile_options(-std=c++11)

### GTSAM 
set(GTSAM_DIR /home/lin/develop/3rd/gtsam/install/lib/cmake/GTSAM)
find_package(GTSAM)
if(GTSAM_FOUND)  
  message(STATUS "Found GTSAM ${GTSAM_VERSION}")
else()
  message(STATUS "GTSAM Not Found")
endif()

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
)

catkin_package()

include_directories(
  ${catkin_INCLUDE_DIRS}
  ${GTSAM_INCLUDE_DIR}
)

link_directories(
	${GTSAM_LIBRARY_DIRS}
)

### build test
add_executable(T_GTSAM_odomTest test/OdometryExample.cpp)
target_link_libraries(T_GTSAM_odomTest gtsam)

Then I run the executable, got the error:

./T_GTSAM_odomTest: error while loading shared libraries: libmetis-gtsam.so: cannot open shared object file: No such file or directory

Any suggestions? Thank you so much!

@CrazyPopLin Hmm that is odd indeed. I got OdometryExample compiling as follows.

Install gtsam as specified in the quick start
Create the following structure:

test-gtsam
├── build
├── CMakeLists.txt
└── OdometryExample.cpp

Populate OdometryExample.cpp as an exact copy from https://github.com/borglab/gtsam/blob/develop/examples/OdometryExample.cpp
Populate CMakeLists.txt as follows:

project(OdometryExample)
cmake_minimum_required(VERSION 2.8)

find_package(GTSAM REQUIRED)

include_directories(${GTSAM_INCLUDE_DIR})

add_executable(OdometryExample OdometryExample.cpp)
target_link_libraries(OdometryExample gtsam)

Build and run the project

cd build
cmake ..
make
./OdometryExample

Please let us know if the following doesn't work for you. (Let's make sure we get OdometryExample working by itself before we try linking it with ROS catkin packages)

Also I do not think you need the following:

link_directories(
	${GTSAM_LIBRARY_DIRS}
)

And you should be linking ${catkin_LIBRARIES} as well:
target_link_libraries(T_GTSAM_odomTest gtsam ${catkin_LIBRARIES})

Also consider populating the arguments for catkin_package() as recommended by ROS: http://wiki.ros.org/catkin/CMakeLists.txt#catkin_package.28.29

linzha0 · 2020-07-09T21:47:32Z

hi @acxz ,thanks for your reply. I did just like the quick start but installed the gtsam a self-defined path, so this time the pure CMakeLists.txt (without ROS env) like below:

project(test_gtsam)
cmake_minimum_required(VERSION 2.8)

### GTSAM 
set(GTSAM_DIR /home/lin/develop/3rd/gtsam/install/lib/cmake/GTSAM)
find_package(GTSAM)
if(GTSAM_FOUND)  
  message(STATUS "Found GTSAM ${GTSAM_VERSION}")
else()
  message(STATUS "GTSAM Not Found")
endif()

include_directories(${GTSAM_INCLUDE_DIR})

add_executable(OdometryExample OdometryExample.cpp)
target_link_libraries(OdometryExample gtsam)

Same issue occurred. Maybe I used Ubuntu 20.04, because this system not tested according Important Installation Notes?

acxz · 2020-07-09T22:02:02Z

did just like the quick start but installed the gtsam a self-defined path

Can you give the exact commands you followed? Without them I am afraid I cannot reproduce your situation and therefore have limited knowledge in helping you.

because this system not tested according Important Installation Notes?

That list sort of outdated anyways tbh. I'm running on Arch Linux with GCC 10.1.0. People that I know use GTSAM on Ubuntu 20.04 as well so it is not a system issue.

Also just to make sure, that local install is the only installation of GTSAM you have on your system right? If not can you ensure that.

linzha0 · 2020-07-09T22:20:06Z

The install commands shown below:

$ cd <my_path>/
$ git clone https://github.com/borglab/gtsam
$ cd gtsam
$ mkdir build && mkdir install
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=<my_path>/gtsam/install ..
$ make check
$ install

The gtsam test project build steps are just like your suggestion.
This is new installed system, and it's first to install gtsam. Please let me know if you have any questions. thanks for your help.

acxz · 2020-07-09T22:22:32Z

And how did you compile your own project?

linzha0 · 2020-07-09T22:23:47Z

The gtsam test project build steps are just like your suggestion.

acxz · 2020-07-09T22:34:35Z

The gtsam test project build steps are just like your suggestion.

Weird those instructions shouldn't even compile your project if GTSAM is installed locally.

After installing GTSAM to a local directory, I built my project with the following commands:

cd build
cmake .. -DCMAKE_PREFIX_PATH=~/local
make

and just to iterate, where I installed GTSAM locally as follows after cloning:

cd gtsam
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX:PATH=$HOME/local
make install

With these steps I still do not receive the libmetis-gtsam issue.
Can you try these exact steps and let me know the output of them?

linzha0 · 2020-07-09T23:57:41Z

Build gtsam

$ cd 
$ mkdir local
$ cd local
$ git clone https://github.com/borglab/gtsam
$ cd gtsam
$ mkdir build 
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX:PATH=$HOME/local
$ make install

The CMake output for building gtsam:

./OdometryExample: error while loading shared libraries: libmetis-gtsam.so: cannot open shared object file: No such file or directory

ProfFan · 2020-07-10T00:14:28Z

Before this is dealt with you can always use LD_LIBRARY_PATH to get going.

linzha0 · 2020-07-10T00:19:19Z

Hi @ProfFan , could you be more specific?

acxz · 2020-07-10T01:38:04Z

@CrazyPopLin followed your steps command by command (except replacing lin with acxz) and I could not reproduce the issue. It seems there is something else amiss.

Can you give us the output of ls ~/local/lib?

As well as the contents of ~/local/gtsam/build/install_manifest.txt

It would be much appreciated if you can post your file as a gist or as a dropdown element in the issue comment.

linzha0 · 2020-07-10T02:01:55Z

cmake libgtsam.so.4 libgtsam_unstable.so.4

Thanks.

linzha0 · 2020-07-10T02:10:35Z

I used the same build steps to install gtsam and build project in Jetson TX2 with jetpack 4.4.2(Ubuntu 18.04), got same error;
Then use same steps to install gtsam and build project in Ubuntu 16.04, it's working.
Just let you know.

ProfFan · 2020-07-10T02:33:05Z

@CrazyPopLin I mean you can add LD_LIBRARY_PATH that points to where libmetis-gtsam.so is in and see if that fixes your issue.

Ref: https://stackoverflow.com/questions/13428910/how-to-set-the-environmental-variable-ld-library-path-in-linux

acxz · 2020-07-10T02:35:02Z

@CrazyPopLin so it seems like that libmetis-gtsam.so is installed, but your executable cannot find it.

Glad to hear it's working on Ubuntu 16, but still very weird that it is not working for you on 18 or 20.

Can you change your CMakeLists.txt as follows and post the output, noting the new get_target_property() commands.

project(test_gtsam)
cmake_minimum_required(VERSION 2.8)

set(GTSAM_DIR /home/acxz/local/lib/cmake/GTSAM)
find_package(GTSAM)
if(GTSAM_FOUND)
  message(STATUS "Found GTSAM ${GTSAM_VERSION}")
else()
  message(STATUS "GTSAM Not Found")
endif()

include_directories(${GTSAM_INCLUDE_DIR})

add_executable(OdometryExample OdometryExample.cpp)
get_target_property(gtsam_link_lib gtsam INTERFACE_LINK_LIBRARIES)
message("${gtsam_link_lib}")
target_link_libraries(OdometryExample gtsam)

I get the following output:

@acxz , this issue is solved by addling following in ~/.bashrc suggested by @ProfFan
export LD_LIBRARY_PATH=/home/lin/local/lib/:$LD_LIBRARY_PATH.

But this issue is wired, so please let me know if you want to debug more. thanks for your suggestion.

dellaert · 2020-07-10T12:50:04Z

Thanks ! Will close for now

acxz · 2020-07-10T12:58:44Z

I am puzzled but out of ideas. Nevetheless, glad to hear you got it working, and I hope you enjoy using GTSAM!

cynosure4sure · 2020-08-27T10:44:00Z

Same issue when upgrading ROS Melodic code from 4.0.2 to 4.0.3 on Ubuntu 18.04. ROS code compiled correctly however at runtime gave error:
error while loading shared libraries: libmetis-gtsam.so: cannot open shared object file: No such file or directory

Adding export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH to ~/.bashrc resolved the issue as mentioned above.

Thank you for the solution.

bloom256 · 2021-04-26T09:33:15Z

Perhaps ldconfig should be called after installing gtsam. See https://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-ldconfig

cynosure4sure · 2021-05-03T11:29:06Z

Perhaps ldconfig should be called after installing gtsam. See https://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-ldconfig

Thank you this fixed the problem.

berndpfrommer · 2021-08-25T20:16:52Z

This is a packaging bug.

jingyibo123 · 2021-09-18T08:51:14Z

ldconfig should not be necessary, and LD_LIBRARY_PATH is a no no for portability

There's clearly a lot missing in the generated GTSAMConfig.cmake and GTSAM-exports.cmake

When installed to a custom path( which is usually the PREFERED way to build and link against a thirdparty project from source), the libgtsam.so is unable to find libmetis-gtsam.so (as seen by ldd libgtsam.so), and import GTSAM with find_package(GTSAM) is quite painful.

AFAIK, either the old fashioned way, define GTSAM_LIBRARIES and GTSAM_LIBRARY_DIR, or the modern way, define cmake targets with correct dependencies...

Correct me if I'm wrong I'm no cmake expert...

berndpfrommer · 2021-10-02T22:12:23Z

When I try to fix this by creating a libgtsam4.triggers file in the debian directory:

activate-noawait ldconfig

I get the following cryptic lintian error when packaging:
E: libgtsam4: repeated-trigger-name activate-noawait ldconfig (line 3) vs activate-noawait ldconfig (line 1)
A web search didn't provide much clarity, but the answer to this stack exchange post mentions that the debian build tools add the trigger automatically, which may result in the above error message.

For now I will not include the ldconfig trigger also because it is not clear if it is still needed with the new package that uses the system-provided libmetis.

jlblancoc · 2021-10-03T20:23:57Z

For the records:

Should [Feature Request] Allow use of system libraries for 3rdparty codebases #292 be updated to mark "libmetis" as solved? (Finally!! Yay! 👍 )
I agree: ldconfig shouldn't be needed to be explicitly called in the Debian packaging, @berndpfrommer

So good to see progress on #292 !

ProfFan · 2021-12-03T14:46:01Z

This is because you have multiple versions of GTSAM installed in different locations. Please search and remove them.

brunoeducsantos · 2021-12-03T14:50:33Z

Thanks a lot ! Indeed that was the problem.

Janphr · 2022-02-27T06:56:17Z

Under 20.04 and GTSAM 4.2.0 following solved it for me:
sudo cp /usr/local/lib/libmetis-gtsam.so /usr/lib

sfod · 2022-12-14T10:16:45Z

I see that even the issue is closed, users encounter it from time to time.
I believe, a proper way to fix it in linux environment is to set RPATH. It can be done using CMAKE_INSTALL_RPATH option.
Something like the following:

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_RPATH='\$ORIGIN:${CMAKE_INSTALL_PREFIX}/lib'

Then, the installed library will have the RUNPATH property (I set CMAKE_INSTALL_PREFIX to /tmp/install):

$ readelf -a /tmp/install/lib/libgtsam.so | fgrep -i runpath     
 0x000000000000001d (RUNPATH)            Library runpath: [$ORIGIN:/tmp/install/lib]

$ ldd /tmp/install/lib/libgtsam.so | fgrep metis
	libmetis-gtsam.so => /tmp/install/lib/libmetis-gtsam.so (0x00007fc3b5f0a000)

If this doesn't work, sometimes CMAKE_SKIP_BUILD_RPATH=OFF and CMAKE_INSTALL_RPATH_USE_LINK_PATH=ON options are also required.

Maybe it should be added by gtsam library, but I' not sure about this.

wienans · 2023-01-20T11:04:24Z

This works:
sudo cp /usr/local/lib/libmetis-gtsam.so /usr/lib
But is not so nice and not the intended way, for me also calling
ldconfig
worked fine on ubuntu 20.04
