问题
I want to write a simple program which uses Trilinos. After many problems with configuration script I've managed to write it, so it launches without any problem. The problem is, when I try to compile my own code ( both Makefile and my test program I've rewritten according to the original examples ), it throws the error:
c++: error trying to exec '/usr/lib/gcc/x86_64-linux-gnu/4.9/cc1plus': execv: Argument list too long
So I tried to launch my Makefile with env -i make to make enough space for "the arguments". It worked, but now it throws another error:
c++: error trying to exec 'cc1plus': execvp: No such file or directory
Makefile:62: recipe for target 'test.o' failed
make: *** [test.o] Error 1
My attempts:
I've tried to find any solution to this problem, but I've found nothing which worked so far.
I've checked if my GCC and G++ are the same version and they are:
gcc (Ubuntu 4.9.1-16ubuntu6) 4.9.1
Copyright (C) 2014 Free Software Foundation, Inc.

Copyright (C) 2014 Free Software Foundation, Inc.

warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
Then I've tried to reinstall G++:
sudo aptitude reinstall g++-4.9
Still, no success.
Finally I've checked, if my g++ command points to the correct destination:
martin@martin-Aspire-E1-531:~$ which g++
/usr/bin/g++
/usr/bin/g++ is a link to the file g++-4.9, which is a correct file to launch the compiler.
So, I don't have any idea what should I do know to compile it correctly. Do you?

回答1:
Finally I've found out that the problem was env -i command - it removed even the g++ path, so the makefile must be launched without it.
回答2:
Is GCC_EXEC_PREFIX set in your environment? Check out https://stackoverflow.com/a/15262886 where there was a very similar issue, resolved by not setting GCC_EXEC_PREFIX in the environment.
