http://www.netgull.com/gcc/releases/gcc-4.5.0/ 에서 GCC 4.5를 다운로드 했지만 설정 / 빌드하려고하면 아래 오류가 발생합니다.

Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

다음 libs는 각 디렉토리에 있습니다.

/usr/lib/libgmp.a
/usr/lib64/libgmp.a

/usr/lib/libmpfr.a
/usr/lib64/libmpfr.a

상자에 libmpc.a 라이브러리가 설치되어 있지 않습니다.

오류를 기반으로 어떻게 알 수 있습니까?

a) libgmp.a 및 libmpfr.a의 현재 버전이 설치되어 있습니다.

b) 잘못된 버전 인 경우 현재 버전을 방해하지 않고 내 버전을 배포하려면 어떻게해야합니까?

---

해당 라이브러리가 설치된 디렉토리 ( /usr/gnu64/lib) 에는 읽을 수있는 텍스트가 포함 된 libgmp.la파일 (및 libmpc.la및 libmpfr.la파일)도 있습니다. SO 버전 정보는 거기에 있지만 '제품 버전'과는 완전히 다릅니다. 대신 링크 호환성에 대해 알려줍니다.

내가 가지고있는 버전을 조사하려고했는데 내가 생각 해낸 이상한 해결책은 -v옵션으로 구축 한 GCC (4.6.1)를 실행하는 것이 었습니다 . 부분적으로 다음과 같이 말했습니다.

GNU C (GCC) version 4.6.1 (x86_64-apple-darwin11.1.0)
    compiled by GNU C version 4.6.1, GMP version 5.0.1, MPFR version 3.0.0, MPC version 0.8.2
warning: GMP header version 5.0.1 differs from library version 5.0.2.
warning: MPFR header version 3.0.0 differs from library version 3.1.0.
warning: MPC header version 0.8.2 differs from library version 0.9.

따라서 GMP 5.0.2가 설치되어있는 것 같습니다 (하지만 5.0.1로 GCC를 빌드했습니다), MPFR 3.1.0 (하지만 3.0.0으로 GCC를 빌드했습니다) 및 MPC 0.9 (0.8.2로 GCC를 빌드했습니다) ). GCC 4.6.2를 컴파일하고 설치하려고했고 아마도 최신 버전이 필요했기 때문에 불일치가 발생했습니다. (성공하지 못했지만 다른 이야기입니다.)

I install my custom-built libraries in /usr/gnu64/lib, and then tell GCC that's where to find them with the configure options --with-mpfr=/usr/gnu64/lib, --with-gmp=/usr/gnu64/lib, --with-mpc=/usr/gnu/64/lib. These paths are hard-wired into GCC and it works from there.

---

Inside the gcc directory, do this command:

./contrib/download_prerequisites

After that script, GMP, MPFR, and MPC will be ready to use. Continue with ./configure.

---

I had the same problem trying to install/compile GCC 4.8.1. Here is how I solved:

In Debian, just run this two commands:

apt-get install libmpc-dev
./configure

---

I had the same problem compiling GCC 4.9 branch.

For Red Hat and Fedora based systems, run the following command:

sudo yum install gmp gmp-devel mpfr mpfr-devel libmpc libmpc-devel

This will install the GNU multiple-precision (MP) libraries for integer, floating point, and complex numbers.
