MRTGのインストール

 

細々とした、ライブラリのコンパイルって
ほとんどのディストリビューションじゃ必要ないんじゃないかな？
既にインストールされていると思うので

cd mrtg

./configure

make

make install

これだけで動くと思う。

Redhat5やCentOS5の場合UTF-8だから
「env LANG=C」をつけないとダメらしい

まずコンパイル作業用のディレクトリ作成
mkdir /usr/local/src/mrtg

その中に必要なライブラリなどダウンロードしておく。

------------------------------------------------------------
zlibのコンパイル
------------------------------------------------------------
cd zlib ; ./configure ; make ; cd ..

------------------------------------------------------------
libpngのコンパイル
------------------------------------------------------------
cd libpng ; \
make -f scripts/makefile.std CC=gcc ZLIBLIB=../zlib ZLIBINC=../zlib ; \
rm *.so.* *.so ; cd ..

------------------------------------------------------------
gdのコンパイル
------------------------------------------------------------
cd gd ; \
env CPPFLAGS="-I../zlib -I../libpng" LDFLAGS="-L../zlib -L../libpng" \
./configure \
--disable-shared \
--without-freetype \
--without-jpeg ; \
make ; cp .libs/* . ; cd ..
