在CentOS上安裝cairo和libcairo2

Question

我進行了搜索，但找不到真正的答案。 我有一台沒有和RHN連接的CentOS服務器。 我需要安裝cairo和libcairo2才能使rapache正常工作。 我確實找到了cairo tar文件，並成功安裝了它。 當我嘗試安裝R cairo軟件包時，失敗並顯示以下錯誤：

      R CMD INSTALL -l /usr/local/lib64/R/library  Cairo_1.5-1.tar.gz
      error: checking whether Cairo programs can be compiled... configure: error: Cannot compile a simple Cairo program. See config.log for details.

有人建議我缺少libcairo2軟件包。 我到處搜索，找不到此軟件包的centos。 有任何想法嗎？ PS我試圖在R中安裝R cairo軟件包，完全相同的錯誤。

定位libcairo輸出：

    /usr/lib/libcairo.so.2
     /usr/lib/libcairo.so.2.9.2
     /usr/lib64/libcairo.a
     /usr/lib64/libcairo.so
    /usr/lib64/libcairo.so.2
    /usr/lib64/libcairo.so.2.9.2
    /usr/local/lib/libcairo-script-interpreter.a
   /usr/local/lib/libcairo-script-interpreter.la
   /usr/local/lib/libcairo-script-interpreter.so
    /usr/local/lib/libcairo-script-interpreter.so.2
    /usr/local/lib/libcairo-script-interpreter.so.2.11000.0
    /usr/local/lib/libcairo.a
    /usr/local/lib/libcairo.la
    /usr/local/lib/libcairo.so
    /usr/local/lib/libcairo.so.2
    /usr/local/lib/libcairo.so.2.11000.0
    /usr/local/lib/cairo/libcairo-trace.a
    /usr/local/lib/cairo/libcairo-trace.la
   /usr/local/lib/cairo/libcairo-trace.so
   /usr/local/lib/cairo/libcairo-trace.so.0
   /usr/local/lib/cairo/libcairo-trace.so.0.0.0

我在config.log文件中看到以下類型的錯誤：

configure:3631: checking whether Cairo programs can be compiled
configure:3645: gcc -std=gnu99 -o conftest -g -O2  -I/usr/local/include/cairo   conftest.c  -L/usr/local/lib -lcairo >&5

locate可以找到該庫的事實表明該庫已成功安裝。 問題可能是盡管R已安裝，但找不到。 檢查libcairo.so的位置是否在您的LD_LIBRARY_PATH 。

看看有什么問題， config.log文件怎么說？
