|2014.x System Generator - Sysgen/Matlab library compatablity issues may occur with Sysgen 2014.x on Linux OS
描述
When running Vivado Sysgen the following error is received:
Invalid MEX-file '/path_to_vivado/2014.1/lib/lnx64.o/matlab/xlgetpath.mexa64': /path_to_matlab/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by /path_to_vivado/2014.1/lib/lnx64.o/librdi_xicom.so)
解决方案
This is a known issue with Vivado Sysgen 2014.x libraries not being compatible with Matlab R2013a, R2013b and R2014a libraries, in particular the libstdc++.so.6 library.
Vivado Design Suite uses a different version of this runtime library.
The version used by Vivado and hence System Generator is GLIBCXX_3.4.18 and the version used by MATLAB is GLIBCXX_3.4.17.
When using 2014.1:
A patch has been prepared to fix this issue in Vivado 2014.1 and is attached to this answer record.
For installation instructions, please review the patch_readme directory within the patch file.
After applying the patch it is necessary to set the following environment variable in your terminal:
setenv USE_VIVADO_RUNTIME_FOR_MATLAB 1Then after invoking System Generator from within this terminal you will receive the following message in the terminal:
We are loading the MATLAB RC File while launching MATLAB
Once this message has been received the patch has been applied correctly.
When using 2014.2:
There is no need to apply the patch in 2014.2 but the environment variable must still be set to enable the solution included in the 2014.2 installation.
setenv USE_VIVADO_RUNTIME_FOR_MATLAB 1Then after invoking System Generator from within this terminal you will receive the following message in the terminal:
We are loading the MATLAB RC File while launching MATLAB
If you have any further problems, please contact Xilinx Technical Support.
When using 2014.3 or newer:
There is no need to apply the patch or set the environment variable.
Sysgen 2014.3 contains a direct resolution for this issue and so it should not be seen.
Note: This AR is written with respect to TCSH.
If using other tools such as BASH shell, use the equivalent commands to set up the environment variables.
