At line 43, the MATLAB command is system(['sumo-gui -c ' '"' scenarioPath '"' ' --remote-port 8873 --start&']); Since I am using Ubuntu 16.04.1 LTS , I fixed scenarioPath . Now, this line is equal to system('sumo-gui -c "/path/to/SUMO/docs/tutorial/traci_tls/data/cross.sumocfg" --remote-port 8873 --start&'); When I run it nothing does happen ( ans=0 ) while when I test the command in bash command line the sumo-gui application starts. I believe the problem is even further

I'm compiling a shared library .so in Ubuntu 32 bit (Have tried doing it under Debian and Ubuntu 64 bit, but none worked either) I keep getting: /usr/lib/libstdc++.so.6: version ``GLIBCXX_3.4.15' not found every time I try to load my plugin. Here's how I'm getting this error: Install latest Ubuntu 32 bit sudo apt-get install build-essential Compile & load my plugin (.so) Here are some links which I found and tried, but none worked for me: (My old question: I somehow got it fixed a few days

Invoking the compiler is the same for both source types, so I'd like to use the same rule and just tweak it to be more flexible. I'd rather not change the OPTIONS variable because it's also used for the linking step, etc. Is there a way to make the rule above more flexible to accommodate both .c and .m files? Thanks 回答1: We

I followed the help on mathworks by making a link in /lib64 as: ln -s /lib/x86_64-linux-gnu/libc.so.6 . That solved the issue.

Edit On the above man page it says: Feature Test Macro Requirements for glibc (see feature_test_macros(7)): The XSI-compliant version of strerror_r() is provided if: (_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600) && ! _GNU_SOURCE Otherwise, the GNU-specific version is provided. It then says in feature_test_macros(7) : If no feature test macros are explicitly defined, then the following feature

MIN() is the macro defined in the standard NSObjCRuntime.h header file as: #if !defined(MIN) #define MIN(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __a : __b; }) #endif During the compilation, the LLVM Compiler 4.1 highlights my instruction showing the warning: "Use of GNU statement expression extension". What does this mean? Is it my fault? If yes, how can I fix it? If not, how can I remove the compiler
