如何提供Matlab與舊版gcc版本？

在我的電腦上，我安裝了gcc 4.4.4的Ubuntu 10.10。我嘗試編譯它使用CUDA一些MEX文件，我收到以下錯誤信息：通過與GCC 4.2.3我可以擺脫錯誤的鏈接Matlab的如何提供Matlab與舊版gcc版本？

我想，但我不知道如何去做吧。

mex -setup給了我以下選項：

1: /home/leMe/Matlab/bin/gccopts.sh : 
     Template Options file for building gcc MEX-files 

    2: /home/leMe/Matlab/bin/mexopts.sh : 
     Template Options file for building MEX-files via the system ANSI compiler

我解決它通過改變我的mexopts.sh file，在~/matlab/R2009b/mexopts.sh（與您的MATLAB版本的變化）

找到你的架構（對我來說這glnxa64），並像這樣改變它：

 ;; 
    glnxa64) #<----------------------- FIND THIS 
     RPATH="-Wl,-rpath-link,$TMW_ROOT/bin/$Arch" 
     # StorageVersion: 1.0 
     # CkeyName: GNU C 
     # CkeyManufacturer: GNU 
     # CkeyLanguage: C 
     # CkeyVersion: 
     CC='gcc-4.1' #<---------------------------------- CHANGE HERE 
     CFLAGS='-ansi -D_GNU_SOURCE' 
     CFLAGS="$CFLAGS -fexceptions" 
     CFLAGS="$CFLAGS -fPIC -fno-omit-frame-pointer -pthread" 
     CLIBS="$RPATH $MLIBS -lm" 
     COPTIMFLAGS='-O -DNDEBUG' 
     CDEBUGFLAGS='-g' 
     CLIBS="$CLIBS -lstdc++" 
     # 
     # C++keyName: GNU C++ 
     # C++keyManufacturer: GNU 
     # C++keyLanguage: C++ 
     # C++keyVersion: 
     CXX='g++-4.1' #<---------------------------------- CHANGE HERE 
     CXXFLAGS='-ansi -D_GNU_SOURCE' 
     CXXFLAGS="$CXXFLAGS -fPIC -fno-omit-frame-pointer -pthread" 
     CXXLIBS="$RPATH $MLIBS -lm" 
     CXXOPTIMFLAGS='-O -DNDEBUG' 
     CXXDEBUGFLAGS='-g'

PS：你還需要安裝正確版本的gcc
