[SOLVED] configure error "A compiler with support for C++11 language features is required."

configure error "A compiler with support for C++11 language features is required."

I am trying to build the breakpad libraries based on the documentation from https://chromium.googlesource.com/breakpad/breakpad/ but when I execute ./configure && make, I get an error when checking for c++11, even though I am currently able to compile with c++11.

Here is the output from ./configure:

configure: error: *** A compiler with support for C++11 language features is required.

Here is the output from g++ --version:

And here is a sample application compiling with c++11:

g++ -std=c++11 -g -c -pedantic -Wall -Wextra -I../boost_1_57_0 -L../boost_1_57_0/stage/lib UtilsText.cpp -o UtilsText.o
g++ -std=c++11 -g -c -pedantic -Wall -Wextra -I../boost_1_57_0 -L../boost_1_57_0/stage/lib UtilsWeb.cpp -o UtilsWeb.o
g++ -std=c++11 -g -c -pedantic -Wall -Wextra -I../boost_1_57_0 -L../boost_1_57_0/stage/lib WorkElement.cpp -o WorkElement.o

I don't know why breakpad is complaining about my g++ not having support for c++11, or if there is a way I can override or add extra parameters so that it correctly detects my compiler.

Any hints on what I might be missing or doing wrong? Is breakpad using another gcc that might be installed in my system?

Here is the config.log file: http://pastebin.com/TuHrmiLv

Solution

While GCC 4.7 does have some C++11 capabilities, it is severely lacking most of the features needed. So while the configure script uses the correct option to enable C++11, the compiler can't actually handle the test-program because it uses features not available in the old GCC 4.7 version you have.

If you want to use Breakpad you need either an older version of Breakpad that supports your old compiler, or you need to update your compiler to a more recent release. The 5 series should have full support for C++11.
