GCC error: terminate called after throwing an instance of 'std:: regex_ error‘ what(): regex

The reason for this error should be gcc Version problem .

View version commands ：
gcc --version

If there is no accident, it should be 4.8.x Version of

Inquiry gcc4.9 To support c++ Regular expression of , So we need to put gcc upgrade .

Find one first gcc4.9 Install the source package of ( Find one for yourself )

mkdir build
…/./configure
make & make install

perform configure There may be a mistake ：
linux : error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.

It indicates that these three libraries need to be installed ：
wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-6.1.0.tar.bz2
wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-3.1.4.tar.bz2
wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-1.0.3.tar.gz

tar.bz2 Unpack the command tar -jxvf
tar.gz Unpack the command tar -zxvf

./configure
make & make install

perform gmp Of configure There may be a mistake ：
error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons)

Explain the lack of m4 This library
wget http://ftp.gnu.org/gnu/m4/m4-1.4.16.tar.bz2

perform ./configure There may be a mistake ：
./stdio.h:477:1: error: ‘gets’ undeclared here (not in a function)
_GL_WARN_ON_USE (gets, “gets is a security hole - use fgets instead”);

Get into m4/lib Find one stdio.in.h The problem of , If you can't find it, try it find -name stdio.in.h

Comment out the first line

_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

Add the following

#if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#endif

Then compile these libraries all the way

It's time to compile gcc When

configure Wrong again.

I suspect your system does not have 32-bit developement libraries (libc and headers). If you have them, rerun configure with --enable-multilib. If you do not have them, and want to build a 64-bit-only compiler, rerun configure with --disable-multilib.

perform
sudo yum install glibc-devel.i686
sudo yum install libgcc.i686

Oh, finally
perform make
make install Walk up

Oh, I forgot to say , If your machine is multi-core, you can perform parallel compilation make -j8 The following numbers represent the audit

You can watch a movie during this period , Not surprisingly, I've finished reading make We're not done yet .....

I feel that it is not the language itself that persuades people to retreat , indicating contrast linux Environment configuration .
