I compiled some codes in Matlab on a Linux system, and .mexa64 files has been generated, but in run time, I get the following error:
Invalid MEX-file '/*.mexa64': /matlab-8.5/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.8' not found.
i tried setting -rpath in make file by two following commands in matlab make file:
LDFLAGS="\$LDFLAGS -rpath=/usr/local/GNU/glibc-2.22/lib/"
LDFLAGS="\$LDFLAGS -dynamic-linker=/usr/local/GNU/glibc-2.22/lib/ld-linux-x86-64.so.2"
But, it cannot solve the problem.
This worked for my case:
Goto your matlab installation:
cd /usr/local/MATLAB/R2015a/sys/os/glnxa64
and rename these two files:
sudo mv libstdc++.so.6 libstdc++.so.6.orig
sudo mv libgcc_s.so.1 libgcc_s.so.1.orig

I'm trying to create my own function (using C) in postgres for which I'm referring this doc: http://www.linuxgazette.cz/139/peterson.html
For compiling - I'm referring: Section 33.9.6 . But, when I run below command:
cc -fpic -c example.c
I get this error:
example.c:1:22: fatal error: postgres.h: No such file or directory
#include "postgres.h"
^
compilation terminated.
I have also installed postgresql-server-dev-all package and tried with the solution provided in this link: How to fix 'postgres.h' file not found problem?
Nothing working for me. Please let me know how I can have postgres.h file.
I'm using postgres-12 on centos -7.
First: If you didn't install PostgreSQL from source, make sure that you installed the headers, which are in the -devel package.
If the problem persists even with the headers installed, the reason is that you forgot to tell the compiler where to look for header files:
cc -fpic -I /location/of/postgres/include -c example.c
To find that location, you can use pg_config:
pg_config --includedir
There is a similar --libdir option to show the library path for when you link the executable.
for ubuntu: apt-get -y install postgresql-server-dev-13 after apt-get -y install postgresql-13
I am using the davidva/gcc49 copr, on Fedora 27.
When I try to compile after running source /usr/bin/gcc49 as the copr webpage describes, I get this error:
/usr/bin/ld: cannot find -lgcc_s
After learning about how the flag -l works for gcc, I learned it is looking for library gcc_s. I found it in /opt/gcc-4.9.3/lib64/gcc/x86_64-fedoraunited-linux-gnu/lib64, which sounds like the right spot for it to be. Why is it not linking? Do I need to add a directory to a library path? If it's LDFLAGS, it's already there because of the file I sourced:
export LDFLAGS="-L/opt/gcc-$gver/$lib/gcc/$gcc_target_platform/$lib/"
What do I need to do to get gcc 4.9 on Fedora 27 to find its library file which is clearly in the LDFLAGS directory?
The problem is that the libgcc_s.so file is in the wrong directory! Just symlink to it in the 4.9.3 directory:
pushd /opt/gcc-4.9.3/lib64/gcc/x86_64-fedoraunited-linux-gnu/4.9.3
sudo cp -p ../lib64/libgcc_s.so.1 .
sudo ln -s libgcc_s.so.1 libgcc_s.so
popd
I guess the /opt/gcc-4.9.3/lib64/gcc/x86_64-fedoraunited-linux-gnu/lib64 directory was supposed to be included in any LDFLAGS parameter, and that might be a weakness of the build process I was using and not the gcc 4.9 package.
Putting this file and appropriately-named symlink in the 4.9.3 directory allows my build process to complete successfully.

There are some posts about this for the older releases of MATLAB, but they don't seem to work for R2016a.
I'm trying to install MatConvNet on Ubuntu 16.04. When I run the vl_compilenn command as described here, it gives me a warning as follows:
Building with 'gcc'.
Warning: You are using gcc version '5.4.1'. The version of gcc is not supported.
The version currently supported with MEX is '4.7.x'. For a list of currently supported
compilers see: http://www.mathworks.com/support/compilers/current_release.
I have already installed gcc-4.7 and g++-4.7 using apt-get install gcc-4.7 g++-4.7. How can I force MATLAB to use these versions and not the default ones?
Few hints, not a complete tutorial how to do it.
Probably the simplest would be to edit the MATLAB's Mex XML configuration file:
mex -setup C
cc = mex.getCompilerConfigurations('C', 'Selected')
edit(cc.MexOpt)
The mex setup usually creates a copy in your home folder (~/.matlab/<version>/mex_C_glnca64.xml), so you should be able to edit it without root.
There you probably need to change the section:
<GCC>
<cmdReturns name="which gcc" />
</GCC>
which I guess searches for the location of the gcc command to your gcc version and assigns it to the $GCC variable. Plus you can change the version name in the header.
Additionally you need to do the same for the C++ language.
This works with R2016b:
Install the required GCC version with apt install (gcc-4.9 and g++-4.9 in my case).
Create a bin folder in your home, i.e. ~/bin.
Create the following links with ln:
ln -s /usr/bin/gcc-4.9 ~/bin/gcc
ln -s /usr/bin/g++-4.9 ~/bin/g++
If using CUDA, create a file called nvcc in the ~/bin folder, with the following contents (don't forget to make it executable: chmod +x ~/bin/nvcc):
Contents:
#!/bin/sh
exec /usr/lib/nvidia-cuda-toolkit/bin/nvcc -ccbin gcc-4.9 "$#"
If necessary replace /usr/lib/nvidia-cuda-toolkit/bin/nvcc with the correct location of the nvcc binary.
Open MATLAB and follow the instructions for compiling MatConvNet.
I have the following system:
Linux 64 bit LTS 12.04
I have multiple installations of opencv library on the system.
I want to know the procedure to remove all opencv libraries from the system.
I am having trouble while executing my program through Eclipse IDE.
Though I can build the project when I try to execute it, it gives the following error:
OpenCV Error: Assertion failed (k == STD_VECTOR_MAT) in release, file /build/buildd /opencv-2.3.1/modules/core/src/matrix.cpp, line 1364
terminate called after throwing an instance of 'cv::Exception'
what(): /build/buildd/opencv-2.3.1/modules/core/src/matrix.cpp:1364: error: (-215) k == STD_VECTOR_MAT in function release
Confusing thing is I am not able to find the path specified in the error i.e.
/build/buildd/opencv-2.3.1/modules/core/src/matrix.cpp
I am able to compile the same source code using command line tool gcc and using pkg-config.
However I am unable to do the same through eclipse IDE.
You can also uninstall by going to the "build" folder directory of opencv from terminal, and execute the following
make uninstall
cd ..
sudo rm -r build
sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*
I remember I used this command a while ago to remove all opencv related things. It is interactive which promote you to remove the file. choose y or n depending.Take your time and be-careful
$> sudo find / -name "*opencv*" -exec rm -i {} \;
The correct way is cd /path/to/cv/build then sudo make uninstall. Of course you will have to have the source code with you
I tried the exec rm thing but nothing changed. Also FYI, sudo apt-get remove libopencv-* did not remove openCV for me
I'm trying to connect to Oracle 10.2.0.4 on a remote system from my intel mac running OSX 10.6 snow leopard. I've tried using perl CPAN to install DBD::Oracle (DBI worked ok) but get compilation errors. Could someone provide an easy to follow guide?
Getting a mac install of perl to play nicely with oracle is a bit of a pain - once it's running it is fantastic, getting it running is a little frustrating..
The below has worked for me on a few different intel macs, there could well be superfluous steps in there and it is likely not going to be the same for other platforms.
This will require use of shell, the root user and a bit of CPANing - nothing too onerous
First off create a directory for the oracle pap - libraries, instant client etc
sudo mkdir /usr/oracle_instantClient64
Download and extract all 64 bit instant client packages from oracle to the above directory
Create a symlink within that directory for one of the files in there
sudo cd /usr/oracle_instantClient64
sudo ln -s /usr/oracle_instantClient64/libclntsh.dylib.10.1 libclntsh.dylib
The following dir is hardcoded into the oracle instant client - god knows why - so need to create and symlink it
sudo mkdir -p /b/227/rdbms/
sudo cd /b/227/rdbms/
sudo ln -s /usr/oracle_instantClient64/ lib
Need to add a couple of environment variables, so edit /etc/profile and add them so they exist for all users:
export ORACLE_HOME=/usr/oracle_instantClient64
export DYLD_LIBRARY_PATH=/usr/oracle_instantClient64
Now try and install DBD::Oracle through CPAN - this will fail, but it means any dependencies will be downloaded and it retrieves the module for us
sudo perl -MCPAN -e shell
install DBD::Oracle
When this fails exit CPAN and head to your .cpan/build dir - if you used automatic config of CPAN it'll be
cd ~/.cpan/build
if you didn't auto configure you can find your build directory with the following command in CPAN
o conf build_dir
Once in the build dir look for the DBD::Oracle dir which has just been created (it'll be called something like DBD-Oracle-1.28-?) and cd into it.
Now we need to switch to the root user. Root isn't enabled as default in osx - for details on enabling see this post on the apple website
Once logged in as root we need to set the above environment variables for root:
export ORACLE_HOME=/usr/oracle_instantClient64
export DYLD_LIBRARY_PATH=/usr/oracle_instantClient64
Now while still logged in as root we need to run the makefile for the module, then make, then install
perl Makefile.pl
make
make install
Assuming that all worked without error log out of root: we're DBD'd up! If this didn't work it's time to bust out google on whatever errors you're seeing
Now just to install the DBI module
sudo perl -MCPAN -e shell
install DBI
Now you're all set - enjoy your perly oracley new life

Correction to this step
perl Makefile.pl
make
install
The last step should be make install
During make, you may encounter an error that looks like :
lipo: can't open input file: /var/tmp//ccIevTzM.out (No such file or directory)
To correct this you must edit the file "Makefile" created after the "perl Makefile.pl" step and remove all occurrences of the following text :
-arch ppc
This will eliminate the error.
The same error described in (2.) will occur during the installation of the DBI module. You must edit the Makefile created after the perl Makefile.pl step and remove all occurrences of the following text :
-arch ppc
It looks with the XCode4 change (removal of PPC arch support) the Perl installation was not updated in any of the 10.6.X updates to also remove PPC binaries (probably because Rosetta is still present).
Because of this, the configuration files retain "-arch ppc" causing all CPAN module compiles with C libraries to fail because MakeMaker's output Makefile contains -arch ppc.
To fix this one can edit the following file:
/System/Library/Perl/5.10.0/darwin-thread-multi-2level/Config_heavy.pl
at line 1219 you'll see:
$archflags = exists($ENV{ARCHFLAGS}) ? $ENV{ARCHFLAGS} : '-arch x86_64 -arch i386 -arch ppc';
change that to:
$archflags = exists($ENV{ARCHFLAGS}) ? $ENV{ARCHFLAGS} : '-arch x86_64 -arch i386';
Once you do this the generated Makefile will be correct.
These are a great set of instructions. I have a few other comments about potential "gotchas".

It seems as though the "Perl MakeFile.pl" command is not finding the version of Perl correctly and I get this error message:

Using Oracle in /usr/oracle_instantClient64
Can't find sqlplus. Pity, it would have helped.
I'm having trouble finding your Oracle version number... trying harder
WARNING: I could not determine Oracle client version so I'll just
default to version 8.0.0.0. Some features of DBD::Oracle may not work.
Oracle version based logic in Makefile.PL may produce erroneous results.
You can use "perl Makefile.PL -V X.Y.Z" to specify a your client version.
Oracle version 8.0.0.0 (8.0)
DBD::Oracle no longer supports Oracle client versions before 9.2
Try a version before 1.25 for 9 and 1.18 for 8! at Makefile.PL line 175.
I've triple checked that I've downloaded and installed the proper 64-bit drivers from Oracle. I also checked to make sure that I'm running 64-bit Perl.
If I force the version number like this:
perl MakeFile.pl -V 10.2.0.4
It completes, but I receive the error message when running "make":
Oracle.c:2267: error: ‘SQLT_BIN’ undeclared (first use in this function)
Oracle.c:2277: error: ‘SQLCS_NCHAR’ undeclared (first use in this function)

make: *** [Oracle.o] Error 1
I realize this is because of the "-arch ppc" argument that needs to be removed from Makefile, but even after removal the removal of all 32-bit references, I still saw the error message.
Running 10.6.8 Snow Leopard with Oracle Driver version 10.2.0.4
I found that the key to this issue was making sure that MakeFile.pl could find the Oracle version.
The problem I ran into was that Safari was downloading the zip files from Oracle.com, but unzipping them and somehow corrupting the library.
Instead, I used a different browser and downloaded all the zip files into one directory. Then I ran the following tar commands:
tar -xf instantclient-basic-10.2.0.4.0-macosx-x64.zip
tar -xf instantclient-sdk-10.2.0.4.0-macosx-x64.zip
tar -xf instantclient-sqlplus-10.2.0.4.0-macosx-x64.zip
The copy all the contents in the folder "instantclient_10_2" to $ORACLE_HOME (set previously)
sudo cp -R instantclient_10_2/* $ORACLE_HOME
Also, I did not need to edit the Makefile generated by the MakeFile.pl script to remove the "-arch ppc" references.
You should not recreate on your machine the same directory structure as of the client libraries packager.
Don't do mkdir -p /b/227/rdbms/
Use MacOSX library header management tools: otool and install_name_tool
For instance, I have updated the library headers to my deployment architecture:
otool -L /usr/oracle_instantclient/11.2.0.3.0-64-bit/libclntsh.dylib.11.1

otool -L libsqlplus.dylib
otool -L libsqlplusic.dylib
otool -L sqlplus

Then, you link your dynamic libraries to the place they're supposed to be.
And you can avoid using that export DYLD_LIBRARY_PATH because you know how to setup your system
