Question

我们是一个研究包含C / C ++代码的R包的团队。该软件包可以成功安装在所有机器上，但只能安装一台。这些都运行相同版本的Mac OS X.我已经提供了用于在我的计算机上安装软件包的日志文件（成功）和同事的计算机（错误）。该软件包依赖于Rcpp软件包和GSL库，两者都已成功安装在两台机器上。

首先，我同事的计算机上的安装将导致两个架构的软件包的编译，g ++抱怨一个未知的-arch参数。但是，通过强制定位单个架构x86_64，似乎可以缓解此问题。值得注意的是，由于这些错误，所有计算机现在都有几个版本的R和g ++。这是链接器的问题吗？是否需要为R及其包使用相同的编译器？对于我的计算机，我从未明确要求使用g++-mp-4.5而不是默认的g ++（版本4.2），所以我认为R会自动检测到它。

如果这有任何帮助，这就是我的Makevars包含的内容：

PKG_LIBS=`$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"` $(SHLIB_OPENMP_CFLAGS) -fopenmp
PKG_CPPFLAGS=$(SHLIB_OPENMP_CXXFLAGS) -fopenmp
PKG_CFLAGS=$(SHLIB_OPENMP_CFLAGS) -fopenmp

$(SHLIB_OPENMP_*FLAGS)标志似乎只在我的计算机上定义;明确添加了-fopenmp个标志，以便软件包可以在所有计算机上运行。

有没有人遇到过类似的问题？任何帮助将不胜感激。

我改变了同事的~/.R/Makevars以符合我的配置

LDFLAGS=-L/opt/local/lib
CC=/opt/local/bin/gcc-mp-4.5 -std=gnu99
CXX=/opt/local/bin/g++-mp-4.5
CPP=/opt/local/bin/gcc-mp-4.5 -std=gnu99 -E
CXXCPP=/opt/local/bin/g++-mp-4.5 -E
CFLAGS=-pipe -O2 -m64
CXXFLAGS=-pipe -O2 -m64
SHLIB_CXXLD=/opt/local/bin/g++-mp-4.5
SHLIB_CXXLDFLAGS=-dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress
SHLIB_LD=/opt/local/bin/gcc-mp-4.5 -std=gnu99
SHLIB_LDFLAGS=-dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress

此外，在发出安装命令时使用了--no-multiarch参数。它现在可以在他的电脑上运行。

问题是因为在代码中使用openMP是硬连线（没有检查）而clang在我提出问题的同时不支持openMP。当我们尝试通过Mac端口使用gcc时，我的同事的R是使用默认（Xcode）编译器安装的。

R包安装在所有机器上都成功，但只有一个
