I get the following error when trying to execute the command sbt/sbt assembly:
[error] Could not create directory
/home/user/Downloads/spark-1.6.0/external/mqtt/target/streams/test/$global/$global/discoveredMainClasses
I have no idea...
Check your permissions for creating.
if you run before this command with sudo and after that try it without sudo you will receive this message.
It was an issue with something being out of date. I tried reinstalling Ubuntu with updates included and it worked this time. I probably could have also done this by checking each package manually, but this was easier.

I'm trying (for hours now) to install the cargo crate diesel_cli for postgres. However, every time I run the recommended cargo command:
cargo install diesel_cli --no-default-features --features postgres
I wait a few minutes just to see the same build fail with this message:
note: LINK : fatal error LNK1181: cannot open input file 'libpq.lib'
error: aborting due to previous error
error: failed to compile `diesel_cli v1.4.1`, intermediate artifacts can be found at `C:\Users\<user name here>\AppData\Local\Temp\cargo-installUU2DtT`
Caused by:
could not compile `diesel_cli`.
I'm running postgres in a docker container and have the binaries on my C:\pgsql with the lib and bin directories both on the PATH so I can't figure out why it's not linking. What else could be required they didn't mention in the docs?
In my case the installation was successful but when I tried to run it this error occured.
maybe this would work for others who have the same problem:
open PowerShell
type in setx PQ_LIB_DIR "C:\Program Files\PostgreSQL\13\lib" (or any other path to your PostgreSQL lib)
restart your PC
run again
I had the same issue with WSL, if you're on Linux probably you could find PostgreSQL lib location and add it to your environment variables.
Update:
The answer below is a work around for older versions. Please check the possibility to execute cargo clean first
Original Version
Adding the folder to the PATH variable didn't help, at least in my case, as by some reason it is not used in the /LIBPATH parameter passed to link.exe.
In my case it was C:\Users\<username>\.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib
You can see it in the beginning of the error message.
Copy libpq.lib in there and it will be used from there.
After installation diesel would require some other assemblies. Copy libcrypto-1_1-x64.dll, libiconv-2.dll and libssl-1_1-x64.dll into the folder showed after where diesel command execution
I had the same error on Ubuntu and for me the following install fixed the issue:
sudo apt install libpq-dev
No need to move files around, just add C:\Program Files\PostgreSQL\14\lib and C:\Program Files\PostgreSQL\14\bin to your PATH. Installing and running diesel should have no problems.
Note: your paths may be different, and remember to close/reopen your terminal so the PATH variable is updated.
(Tested on Windows 10)
To give clear steps for windows:
Add C:\Users<username>.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib in the path in environment variables
Copy libpq.lib that is in C:\Program Files\PostgreSQL\14\lib (obviously this is with version 14) and paste it in C:\Users<username>.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib
If you've attempted to cargo build (or anything that runs the build scripts for libpq rust crate) when your environment was invalid, then you need to do a cargo clean after fixing your environment otherwise you'll still get the libpq.lib not found error even when it's in your PATH. The other answers where you copy the file into another directory are just hacks
You can instead add the path to .../lib to the compilers' library search paths, using RUSTFLAGS environment variable. It works both for installing diesel_cli and for building your projects.
RUSTFLAGS='-L /usr/local/pgsql/lib' cargo build
On Windows with EDB installer, the path contains a space, so use CARGO_ENCODED_RUSTFLAGS instead. For PowerShell:
$env:CARGO_ENCODED_RUSTFLAGS = "-L`u{1f}C:\Program Files\PostgreSQL\14\lib"
I am trying to compile matconvnet-1.0-beta20 with Matlab 2016a on Ubuntu 16.04. Initial phase of compilation works fine:
untar('http://www.vlfeat.org/matconvnet/download/matconvnet-1.0-beta20.tar.gz') ;
cd matconvnet-1.0-beta20
run matlab/vl_compilenn
The error happens when I run vl_simplenn(network, image) which gives following error:
Invalid MEX-file '/home/matconvnet-1.0-beta20/matlab/mex/vl_nnconv.mexa64':
/usr/local/MATLAB/R2016a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version
`GLIBCXX_3.4.21' not found (required by /home/matconvnet-1.0-beta20/matlab/mex/vl_nnconv.mexa64)
To understand the cause of problem, I run /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBC which doesn't give any output bash: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: Permission denied
Also more /usr/lib/x86_64-linux-gnu/libstdc++.so.6 gives no output:
******** /usr/lib/x86_64-linux-gnu/libstdc++.so.6: Not a text file ********
I did some research and found some possible solutions:
http://it.mathworks.com/matlabcentral/newsreader/view_thread/162466
The problem is that MATLAB secretly changes LD_LIBRARY_PATH on startup
to point to the MATLAB version of GLIBC++, so that GLIBC++ 3.4.9 can
no longer be found. The solution is to modify matlab/bin/.matlab7rc.sh
so that "LDPATH_PREFIX" contains the path to the version of GLIB
installed with your compiler, then this is found before the
matlab-supplied library.
so I edited /usr/local/MATLAB/R2016a/bin/.matlab7rc.sh and modified LDPATH_PREFIX='' in 195th line to LDPATH_PREFIX='/usr/lib/x86_64-linux-gnu'.
After applying this change, the problem still exist.
As suggested here, I copied .matlab7rc.sh to current working directory of project, but still error persist.
https://askubuntu.com/questions/719028/version-glibcxx-3-4-21-not-found
According to first answer, running this command
ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6
gives an error:
ln: failed to create symbolic link 'usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6': No such file or directory
Seems like second solution suggests changes of LD_PRELOAD path in .matlab7rc.sh, but it is not anywhere inside the file.
How to tell mex to link with the libstdc++.so.6 in /usr/lib instead of the one in the MATLAB directory?
From Matlab directory in /usr/local/MATLAB/R2016a/bin$ I run
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu/libstdc++.so.6
but the problem still exist.
Maybe there I didn't apply the solution in the correct way Or maybe there is another solution elsewhere that I didn't find. Please let me know, I am very confused!!!
You need before execute (matlab in my case) add path of library:
In console execute this:
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 matlab
I had the same problem.
In my case, to solve it, I first ran "locate" to list all the possible versions of the library in the system.
locate libstdc++
As an example, I report the result on my system
I then set the most recent version of "lib" by exporting the environment variable:
export LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21"
So, the fullpath of the library to be set depends on where it is allocated in your system.
There are 2 possible solutions:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu/libstdc++.so.6
Install this package:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
MAYBE the second solution you mentioned really works, but you have done it before. So you cannot operate in the same way again because you have ever linked /usr/lib/x86_64-linux-gnu/libstdc++.so.6 to usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6. TRY rebooting?
Also, you use MATLAB R2016a, but this command applies to R2014a. Was it that you ignore this point?
The error is:
Error using mxlpsolve
Failed to initialise lpsolve library.
I run the
Makefile.m
in the folder and the compiliation, it says everything compiled fine. Where do i need to put mslpsolve and where do i find it?
I used the following guide to solve the same problem:
http://lp-solve.2324885.n4.nabble.com/Fwd-Re-lpsolve-in-MATLAB-on-Mac-OS-X-10-8-2-td1770.html
the only thing that was missed within the guide and I added it up is as follows:
$ cd $HOME/Documents/MATLAB/lp_solve_5.5/extra/MATLAB/lpsolve
$ sudo ln -s /opt/local/lib/liblpsolve55.dylib liblpsolve55.so
make sure that you have installed lp_solve package already.
I am trying to install sipp with pcap-replay on winows7.
I have installed cygwnin, libncurse, and winpcap. I was trying to patch cygwin with IPv6 using the URL http://cygwin.win6.jp/cygwin-ipv6/, but it couldn't get the setup.ini file.
So I copied to local directory and upgrade, but it said no new updates.
And if I try to complie sipp. it gives error
$ ./configure.ac --with-pcap
./configure.ac: line 3: syntax error near unexpected token [SIPp],'
./configure.ac: line 3:AC_INIT([SIPp], [3.3], [sipp-users#lists.sourceforge.net], [sipp])'
Could anyone help me in getting sipp be installed on windows?
I download sipp.3.3.990 it has ./configure and was able to install on Linux.
But now on windows it still fails saying ncurse is not present. But I have downloaded it.
How do I troubleshoot it from here?
You can follow below steps to generate configure from configure.ac.
$> autoreconf -i
Now, you will see a configure file created at the same location.
To run the above command, following packages are required: automake,ncurses-devel,libncurses,M4 and autoconf.
if any of the above packages are missing run the cygwin setup file again and select the packages on the package selection screen and click install.
i've izpack installer Scala 2.8.1 after install it at /usr/local/scala and set environment variable at etc/environment it's work normally for execute command like scala or scalac, but if i execute sbaz with sudo, the error message show like
sudo: sbaz: command not found
So i try to execute sbaz-setup new_sbaz_directory without sudo, but after i tried to execute command like
sbaz install sbt
Again the error show like
java.io.FileNotFoundException: /usr/local/scala/meta/.lock (Permission denied)
Why the sbaz not pointing to my sbaz_directory after execute sbaz-setup command ? Is there any solution for my problem ? Thank you
I don't know the cause of the problem, likely a JVM or Scala crash which left a .lock file.
You can get sbaz to work again by changing the permissions on the .lock file, which will then be deleted when sbaz will run anew :
sudo chmod 777 /usr/local/scala/meta/.lock
then :
sbaz install sbt
Allowing 777 permission on the file looks scary, but I didn't find any other way to delete the .lock file than by letting sbaz run and delete it by itself...
