链接错误安装Rcpp"找不到-lintl的库"

Question

在尝试安装一些Rcpp作为依赖项的R软件包时,我偶然发现了一个链接器错误.我的设置是由Homebrew安装的Mac OS X 10.9.1(Mavericks),R 3.0.2.这是错误输出:

Answer 1

显然,libintl是gettext包的一部分.我做了以下,可能是多余的重新安装,以确保我的副本是最新的:

$ brew install gettext
Warning: gettext-0.18.3.2 already installed
$ brew reinstall gettext
==> Reinstalling gettext 
==> Downloading http://ftpmirror.gnu.org/gettext/gettext-0.18.3.2.tar.gz
Already downloaded: /Library/Caches/Homebrew/gettext-0.18.3.2.tar.gz
==> ./configure --prefix=/usr/local/Cellar/gettext/0.18.3.2 --with-included-gettext --with-included-glib --with-included-libcroco --with-included-libunistring --with-emac
==> make
==> make install
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.

OS X provides the BSD gettext library and some software gets confused if both are in the library path.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/gettext/lib
    CPPFLAGS: -I/usr/local/opt/gettext/include

它在上面的输出中说brew没有符号链接库,这可能解释了为什么install.packages找不到它.诀窍是将库路径添加到〜/ .R/Makevars中,如下所示:

PKG_LIBS=-L/usr/local/Cellar/gettext/0.18.3.2/lib

这个答案是修改Giupo的答案,因为它包含一个拼写错误,但我认为重要的是要比评论更突出.该解决方案是一种非常有效的方法从Homebrew安装Rserve包,而不会在OSX上造成更广泛的问题:

    flags="CPPFLAGS=-I/usr/local/opt/gettext/lib LDFLAGS=-L/usr/local/opt/gettext/include"
    install.packages('Rserve', configure.args=flags)

为了减少命名空间污染,可以在本地包装:

    local({
           flags="CPPFLAGS=-I/usr/local/opt/gettext/lib LDFLAGS=-L/usr/local/opt/gettext/include"
           install.packages('Rserve', configure.args=flags)})
