我构建了一个R包,它使用Rcpp并链接到第三方共享对象(libbarraopt.so)(它也链接到其他共享对象,例如liboptsrvr.so在它自己的目录中).为了确保它能够找到它链接的那些共享对象,我将以下变量放入~/.Renviron:
BARRA_OPS_HOME=${HOME}/bin/BarraOptimizer8.5
在包中,我创建了以下内容src/Makevars:
BARRA_LIB=$(BARRA_OPS_HOME)/lib/intel64
BARRA_INCLUDE=$(BARRA_OPS_HOME)/include
PKG_CXXFLAGS=-I$(BARRA_INCLUDE)
PKG_CFLAGS=-I$(BARRA_INCLUDE)
PKG_LIBS=-L$(BARRA_LIB) -Wl,-R,$(BARRA_LIB) -lbarraopt
在Ubuntu 16.04下,我可以成功构建,加载和使用包,没有任何问题.但是,当我将操作系统升级到17.10时测试完全相同的软件包时,可以构建软件包,但无法加载,说:
