Question

参考URL
https://qiita.com/ma91n/items/e188b0d5d21fe7aa0de7

上記URLを参考に地図経路検索サーバを構築してますが、次の環境でcmakeのコマンドが正しく実行できません。

環境

# cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)

# gcc --version
gcc (GCC) 7.3.0
Copyright (C) 2017 Free Software Foundation, Inc.

# cmake --version
cmake version 3.20.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

コマンド実行結果

上記の環境にてコマンドの事項結果が以下の通りになります。

# cmake ..
CMake Deprecation Warning at CMakeLists.txt:57 (cmake_policy):
  The OLD behavior for policy CMP0048 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

調べた事

GCCのバージョンを5.0以上にアップグレードする旨エラーが出ております。

しかしGCCのバージョンは7.3.0の為、原因が分からない状態です。

Answer 1

もしかしてコンパイラがGCC5未満の状態でCMakeを実行したことがあって、その後GCCをアップデートして、またCMakeを実行したのではないですか？

だとしたらbuildディレクトリにCMakeのキャッシュが残っているせいだと思いますので、buildディレクトリの中身を全部削除してからcmake ..を実行してください。

---

それでもCMakeがコンパイラの検出を誤るようなら...ちゃんとGCC7が検出されるように設定する必要がありますね。この検出の仕組みは定かではありませんが、Unix Makefilesなら多分環境変数PATHの設定だけのような気もするので、見直してください。でもたぶんそれは問題ないのだと思いますが...

コンパイラを環境変数かオプション引数で指定する手段もあります。

How do I use a different compiler?

Your GeneratorのところはUnix Makefilesですね。

もしかしたらCMAKE_CXX_COMPILER_VERSIONやCMAKE_CXX_COMPILER_IDも設定する必要があるかもしれません。

ありがとうございます。

buildディレクトリ内のファイルを削除して実行しましたが症状変わらず次のコマンドを実行しても変化なしでした。
```

ログより何処が原因なのか未だわかりませんが。教えて頂いたCMAKE_CXX_COMPILER_VERSIONの変数によりCMakeLists.txtを確認したところ、
```
if(CMAKE_CXX_COMPILER_ID MATCHES "GNU")
if(CMAKE_CXX_COMPILER_VERSION VERSION_LESS 5.0)
message(FATAL_ERROR "GCC>=5.0 required. In case you are on Ubuntu upgrade via ppa:ubuntu-toolchain-r/test")
endif()
elseif(CMAKE_CXX_COMPILER_ID MATCHES "Clang")
if(CMAKE_CXX_COMPILER_VERSION VERSION_LESS 3.4)
message(FATAL_ERROR "Clang>=3.4 required. In case you are on Ubuntu upgrade via http://apt.llvm.org")
endif()
endif()
```
のコードより
```
GCC>=5.0 required. In case you are on Ubuntu upgrade via ppa:ubuntu-toolchain-r/test
```
のエラーが原因で止まっているように見えないように感じます。

私の認識が間違っているのでしょうか？

ログに
gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
って表示されてますね...

ls -l /usr/bin/cc
/usr/bin/cc --version
してみてください。

ありがとうございます。

教えて頂いたコマンドを実行した結果5.0以下のバージョンが表示されたので原因に近づいてるような気がします。

しかし、

gcc --version
gcc (GCC) 7.3.0
Copyright (C) 2017 Free Software Foundation, Inc.

なのに何故違うバージョンで認識されるのか、また7.3.0をどうすれば認識されるのかその方法を調べますが、今回の「/usr/bin/cc --version」での確認に行き着けなかった事を含め、対応策についてご教授いただけますでしょうか？

[itagagaki]

type gcc
して、そのgcc 7.3.0のパスを確認してください。/usr/local/bin/gcc と仮定すれば、
cmake -D CMAKE_C_COMPILER=/usr/local/bin/gcc -D CMAKE_CXX_COMPILER=/usr/local/bin/g++ ..
で行けるかと。
